Description

The present invention relates to an information presentation system, a program, and an information storage medium.

  In recent years, a system has been proposed in which a user's position is specified using a GPS sensor or the like, content is selected based on the specified position, and presented to the user. According to this information presentation system, it is possible to provide the user with appropriate content according to the position of the user, which is highly convenient for the user.

  However, position data (latitude / longitude) obtained by GPS is merely data per se, and does not directly mean the place where the user stays. Therefore, how to identify a place that is meaningful to the user from such position data is an important issue.

  However, conventional information presentation systems do not handle the user's place of stay necessary for content selection hierarchically, but treat it only singly. Therefore, it is impossible to properly detect what the place is meaningful for the user who stays at the place, and therefore, it is possible to provide the user with appropriate content according to the place. could not.

  Moreover, in the information presentation systems so far, there is a problem that information that has become necessary can be presented to the user as push information without operation, but information that is potentially necessary cannot be presented. . It is convenient to continue presenting only the information that reveals the necessity, but it only supports the extension of daily life patterns. There was a problem that it was hard to be born and could not lead to a fulfilling life. On the other hand, there are problems of complexity and anxiety in extraordinary new experiences.

  Therefore, it is desirable to provide an opportunity to change daily life patterns, and to lower the hurdles of extraordinary experiences and realize an information presentation system that can appropriately balance daily and extraordinary in daily life. It is.

  Patent Document 1 discloses a system for monitoring the abnormal behavior of an elderly person living alone, but this system automatically detects when the elderly person living alone becomes abnormal and becomes unable to act. It is not intended to be an inspiring ubiquitous service that gives users awareness and encourages their own growth.

  According to some aspects of the present invention, it is possible to provide an information presentation system, an information processing system, a program, and an information storage medium capable of extracting a place meaningful to a user and realizing appropriate content presentation and the like.

  The present invention relates to a situation estimation unit that estimates a user's situation, a content selection unit that selects content corresponding to a user's place of stay from content that is a candidate for presentation to the user, and information about the selected content. A presentation control unit that performs control for presenting to the user by the presenting unit, the situation estimation unit determines whether the user is staying in an area or a spot narrower than the area, The content selection unit selects content for the area when it is determined that the user is staying in the area, and is the content for spot when it is determined that the user is staying at the spot. It relates to the information presentation system to select. The present invention also relates to a program that causes a computer to function as each of the above-described units, or a computer-readable information storage medium that stores the program.

  According to the present invention, it is determined whether the user is staying in an area or a spot. When the user stays in the area, the area content is selected. When the user stays in the spot, the spot content is selected and presented by the information presenting unit. In this way, areas that have different meanings for the user are extracted as spots that are narrower than the area, for example, and the spot content is selected and presented to the user, or is extracted as an area and the area content is selected. Can be presented to the user. Therefore, it is possible to present appropriate content corresponding to a place that is meaningful to the user.

  Further, the present invention may include an area / spot setting unit that variably sets the width of each area of the plurality of areas and variably sets the width of each spot of the plurality of spots.

  As described above, if the area and the size of each spot are variably set, a place meaningful to the user can be appropriately extracted from the position data of the user.

  In the present invention, the situation estimation unit may determine whether the user is staying in an area or a spot based on a standard deviation of the user's position within a predetermined time.

  In this way, the place where the user is staying can be specified as a meaningful area such as an area or a spot by statistical processing for obtaining the standard deviation of the user's position within a predetermined period.

  In the present invention, the situation estimation unit determines whether the user stays in the area based on whether the standard deviation of the user's position within a predetermined period is equal to or less than a predetermined first threshold value. Whether the user's position standard deviation within a predetermined period is equal to or smaller than a predetermined second threshold value that is smaller than the first threshold value. You may decide whether you are staying in or not.

  In this way, by setting the first threshold value and the second threshold value, it becomes possible to extract an area or spot that is meaningful to the user.

  In the present invention, the content selection unit may select spot content or area content when it is determined that the user is staying at a spot in the area.

  In this way, when the user stays at a spot in the area, it is possible to present spot content or present an area spot according to the user's situation.

  In the present invention, when it is determined that the user is staying at a spot in the area, the content selection unit preferentially selects the content for the spot, and the user places other than the spot in the area. If it is determined that the user is staying in the area, the area content may be selected.

  In this way, it is possible to control such that spot content is preferentially presented when a spot is identified, and area content is presented when a spot is not identified.

  The present invention further includes a dailyness evaluation unit that performs a process for evaluating the dailyness of the user, and the content selection unit may select content based on the evaluation result of the dailyness of the user with respect to the place where the user stays. Good.

  In this way, it is possible to present content that reflects the user's daily life. For example, the user's daily life pattern can be changed or noticed, or the user's complexity and anxiety can be removed in an extraordinary experience. It becomes possible to do.

  Further, in the present invention, when it is determined that the user is staying in the area, the daily life evaluation unit evaluates the user's daily life for the area and determines that the user is staying at the spot. In this case, the user's everydayness with respect to the spot is evaluated, and when the content selection unit determines that the user is staying in the area, the content selection unit determines the content based on the evaluation result of the user's everydayness with respect to the area. When it is determined that the user is staying at the spot, the content may be selected based on the evaluation result of the user's dailyness with respect to the spot.

  In this way, it is possible to evaluate the user's daily level for each spot or area, and present appropriate content to the user based on the evaluation result of the daily level.

  In the present invention, when it is determined that the user is staying at a spot in the area, the dailyity evaluation unit evaluates both the dailyness of the user for the area and the dailyness of the user for the spot, The content selection unit selects the content based on the evaluation result of the user's ordinary degree with respect to the area, selects the content based on the evaluation result of the user's ordinary degree with respect to the spot, and the user places other than the spot in the area If it is determined that the user stays in the area, the daily life evaluation unit evaluates the daily life of the user with respect to the area, and the content selection unit selects the content based on the evaluation result of the daily life of the user with respect to the area. You may choose.

  In this way, areas that have different meanings for the user can be cut out as spots that are narrower than the area and the dailyness can be evaluated, so that content can be selected and presented to the user based on a more accurate and appropriate dailyness. It becomes like this.

  Further, the present invention includes a dailyness information storage unit that stores an everydayness level in association with an area or a spot where the user stays, and the dailyness level evaluation unit includes the dailyness level associated with the area or spot where the user stays. May be read from the daily life information storage unit to evaluate the daily life of the user.

  In this way, the dailyness of the area or spot can be evaluated by a simple process by associating the dailyness with the area or spot in the dailyness information storage unit.

  In addition, the present invention includes a situation estimation unit that estimates a user's situation and a dailyness evaluation unit that performs a process of evaluating the user's everydayness, wherein the situation estimation unit determines whether the user is staying in an area, If the user determines that the user is staying in the area, the daily life evaluation unit evaluates the user's daily life for the area, and the user If it is determined that the user is staying at the site, the present invention relates to an information processing system that evaluates the user's everydayness with respect to the spot.

  According to the present invention, it is determined whether the user is staying in an area or a spot. When the user stays in the area, the user's everyday level with respect to the area is evaluated. When the user stays at the spot, the user's daily level with respect to the spot is evaluated. Therefore, an area having a different meaning for the user can be cut out as a spot narrower than the area, and the everydayness can be evaluated, so that a more accurate and appropriate everydayness evaluation process can be realized.

  In the present invention, the situation estimation unit may determine whether the user stays in an area or a spot based on a standard deviation of the user's position within a predetermined time.

  In the present invention, when it is determined that the user is staying at a spot in the area, the dailyness evaluation unit evaluates both the user's dailyness for the area and the user's dailyness for the spot, When it is determined that the user is staying at a place other than the spot in the area, the user's dailyness with respect to the area may be evaluated.

Built-in external sound microphone. The bone conduction microphone detects a body sound which is a vibration generated from the body during speech and mastication and propagating through the body. The external sound microphone detects sound that is vibration that is conducted outside the body in response to an utterance and external sound including environmental noise. Then, by comparing the power of the sound captured by the bone conduction microphone and the external sound microphone in unit time, etc., the utterance possibility and mastication possibility are measured.

  The GPS sensor 550 is a sensor that detects the position (location) of the user. Instead of the GPS sensor 550, a location information service of a mobile phone or location information of a wireless LAN in the vicinity may be used. The face color sensor 560, for example, arranges an optical sensor near the face, and measures the face color by comparing the light intensity after passing through a plurality of optical bandpass filters. The pupil size sensor 561, for example, places a camera near the pupil and analyzes the camera signal to measure the size of the pupil.

2. Configuration Example FIG. 2 shows a system configuration example of the information presentation system (information processing system) of this embodiment. The information presentation system in FIG. 2 can be realized by, for example, the portable electronic device 100 in FIG.

  The processing unit 102 performs various processes based on operation information from an operation unit (not shown), sensor information acquired from the wearable sensor 150, and the like. For example, sensor information acquisition processing, various types of calculation processing, evaluation processing, and information presentation control processing by the information presentation unit 142 such as a display are performed. The function of the processing unit 102 can be realized by hardware such as various processors (CPU, etc.), ASIC (gate array, etc.), a program stored in the information storage medium 130 (optical disc, IC card, HDD, etc.), and the like.

  The storage unit 120 serves as a work area for the processing unit 102, the communication unit 138, and the like, and functions thereof can be realized by a memory such as a RAM or an HDD (hard disk drive). The storage unit 120 includes a content information storage unit 122, an area / spot information storage unit 123, a dailyness information storage unit 124, and a schedule information storage unit 126.

  The content information storage unit 122 (content database) stores content information such as images, video, music, audio, text (characters, sentences), or various data. This content may be generated in real time, or may be downloaded from the outside via the communication unit 138, for example. The content information storage unit 122 can store meta information (additional information) associated with the content.

  The area / spot information storage unit 123 stores various types of information related to areas and spots. For example, location information and area information (standard deviation threshold information and distribution range information) indicating the area and spot size are stored.

  Dailyness information storage unit 124 (dailyness database) stores dailyness information. For example, the ordinary degree is stored in association with the area or spot where the user stays. Alternatively, the dailyness is stored in association with the stay location (area, spot) and stay time zone. For example, the dailyness information storage unit 124 stores the dailyness corresponding to each of a plurality of staying places where the user has stayed in the past in association with each other. Alternatively, for each combination of staying place and staying time zone, the corresponding dailyness is stored in association with each other. The schedule information storage unit 126 stores user schedule information (schedule data, schedule information).

  The information storage medium 130 (a computer-readable medium) stores programs, data, and the like, and its function can be realized by an optical disk (CD, DVD) or the like. The processing unit 102 performs various processes of the present embodiment based on a program (data) stored in the information storage medium 130. That is, in the information storage medium 130, a program for causing a computer (an apparatus including an operation unit, a processing unit, a storage unit, and an output unit) to function as each unit of the present embodiment (a program for causing the computer to execute processing of each unit). Is memorized.

  The processing unit 102 includes a sensor information acquisition unit 104, a situation estimation unit (location specifying unit) 106, an area / spot setting unit 108, an everydayness evaluation unit 110, a content selection unit 112, and a presentation control unit (display control unit) 118. . Note that various modifications may be made such as omitting some of these components (for example, the dailyness evaluation unit, the content selection unit, and the presentation control unit) or adding other components.

  The sensor information acquisition unit 104 acquires sensor information from the wearable sensor 150 (sensor in a broad sense). Specifically, the wearable sensor 150 is a behavior sensor that measures user behavior (walking, conversation, meal, limb movement, emotional expression, sleep, etc.), user status (fatigue, tension, hunger, mental status, body Including at least one of a state sensor for measuring a state or an event occurring in the user) and an environment sensor for measuring the user environment (location, time, brightness, temperature, humidity, etc.) The unit 104 acquires sensor information from these sensors.

  The sensor may be the sensor device itself, or may be a sensor device including a control unit, a communication unit, and the like in addition to the sensor device. The sensor information may be sensor primary information obtained directly from the sensor, or sensor secondary information obtained by processing (information processing) the sensor primary information.

  The situation estimation unit (situation identification unit) 106 is based on the information including the sensor information acquired by the sensor information acquisition unit 104, and the user's situation such as the user's stay location (at least one of the user's behavior, state, and environment). ) Is estimated (identified). Specifically, multiplication processing or addition processing of the acquired sensor information is performed to realize various calculation processing for sensor information filtering processing (selection processing) or analysis processing. And the situation identification process which is a process which estimates a user's present condition is performed. Alternatively, a situation prediction process that is a process for estimating the future situation of the user is performed.

  Note that the user situation estimated by the situation estimation unit 106 is, for example, the user's behavior, state, or environment. The estimation of the user's behavior is based on the information of the behavior sensor worn by the user, and the state of the user's stationary / walking / running / sitting / laying down / stepping up / down the stairs is determined, or sensors (external) This can be realized by determining the user's action / posture state using a camera or a home sensor), or determining the user's staying / moving state based on the position locus obtained by the position detection sensor. The user's state is a user's mental state or physical state. The estimation of the user's state can be realized by discriminating stress, excitement, tension, health condition, etc. based on the information of the biosensor worn by the user. The user environment includes user location information, time information, ambient environment information, and the like. The user's environment is estimated by using the position detection sensor to determine where the user is staying (current location), using the clock to obtain the year, month, date, day of the week, and time, and using the surrounding environment sensor to detect the temperature, atmospheric pressure, illuminance, This can be achieved by acquiring noise. In this case, since it is difficult to completely and accurately specify the user situation based on the sensor information, the certainty of situation estimation by the situation estimation unit 106 has a certain range.

  Information other than sensor information may be used for estimating the user situation. Specifically, the user situation is estimated using the user's schedule information (schedule data, schedule information) stored in the schedule information storage unit 126, or external information acquired through the communication unit 138 or the like. Also good. For example, the user's future schedule is estimated based on the schedule table input by the user, or an incidental schedule is estimated from the input schedule. Alternatively, based on external information such as information acquired from the web information or external database via the Internet (for example, today's weather / traffic information) or information acquired from other users (for example, contact information from other users). To estimate the user situation.

  If such schedule information or external information is used, the accuracy of situation estimation can be improved as compared with the case where the user situation is estimated using only sensor information. For example, by estimating the user's behavior by combining the sensor information and the schedule information, it is possible to estimate the user's behavior more reliably.

  In this embodiment, the situation estimation unit (location specifying unit) 106 specifies the place where the user stays. For example, an area and a spot narrower than the area are specified as the user's staying place, and it is determined whether the user is staying in the area or a spot narrower than the area. Specifically, the standard deviation of the user's position within a predetermined time is obtained. Based on this standard deviation, it is determined whether the user is staying in the area or spot. More specifically, it is determined whether or not the user stays in the area based on whether or not the standard deviation of the user's position within a predetermined period is equal to or less than the first threshold value. Whether or not the user stays in the spot based on whether or not the standard deviation of the user's position within a predetermined period is equal to or smaller than a second threshold value that is smaller than the first threshold value. Determine whether. The predetermined period for obtaining the area and the predetermined period for obtaining the spot may be the same or different. Further, instead of a two-stage section (granularity) such as an area and a spot, a three-stage or more section may be used. The spot may be a place in the area or a place outside the area.

  The location of the user's stay (area, spot) is determined using a GPS sensor, a location information service of a cellular phone or location information of a wireless LAN in the vicinity, and map information, etc. Can be used to identify the location.

  An area / spot setting unit (place setting unit) 108 performs an area or spot setting process. For example, the width of each area of the plurality of areas is variably set. In addition, the size of each spot of the plurality of spots is set variably. Specifically, when the situation estimation unit 106 compares the standard deviation of the user position with the first and second threshold values, the first threshold value is varied for each of the plurality of areas. Set to. The second threshold value is variably set for each spot of the plurality of spots. As described above, the setting information (first threshold value, second threshold value, etc.) of the area and spot whose width is variably set is stored in the area / spot information storage unit 123.

  The everyday degree evaluation unit 110 performs an evaluation process of the daily degree (unusual degree) of the user. For example, the everyday degree of the user is evaluated (determined) based on the acquired sensor information and the like. For example, when a user's stay location is specified based on latitude and longitude information from GPS or the like, the dailyness is evaluated from the frequency of past stay experience at that location.

  Specifically, when it is determined that the user is staying (positioning) in the area, the everydayness evaluation unit 110 evaluates the everydayness of the user with respect to the area. For example, the dailyness is evaluated from the frequency of past experience of the user in the area. Further, when it is determined that the user is staying (positioning) at the spot, the user's everydayness with respect to the spot is evaluated. For example, the usualness level is evaluated from the frequency of the past stay experience of the user at the spot.

  When it is determined that the user is staying in the area, the content selection unit 112 selects content for the area. On the other hand, if it is determined that the user is staying at the spot, the content for the spot is selected. Here, the area content is, for example, content associated with the area, and is information that arouses the user's interest in the area or information that supports the user's activities in the area. Similarly, the spot content is, for example, content associated with a spot, such as information that arouses the user's interest in the spot or information that supports the user's activities in the spot.

  The content selection unit 112 may select spot content or area content when it is determined that the user is staying at a spot in the area. For example, when it is determined that the user is staying at a spot in the area, the spot content is preferentially selected. On the other hand, when it is determined that the user is staying at a place other than the spot in the area, the content for the area is selected. For example, when the user stays at a spot in the area, first, an appropriate content is selected from the content for the spot and presented. After that, the area content is selected, or the area content is not selected. On the other hand, when the user is staying at a place other than the spot in the area, the content for the area is selected and presented.

  In addition, when the dailyness level of the user is evaluated by the dailyness level evaluation unit 110, the content selection unit 112 may select content based on the evaluation result of the dailyness level. For example, when it is determined that the user is staying in the area, the content selection unit 112 selects the content based on the evaluation result of the user's dailyness with respect to the area. For example, if staying in the area is daily for the user, select content that leads the user to an extraordinary, and if staying in the area is unusual for the user, Select content that leads to.

  If it is determined that the user is staying at the spot, the content is selected based on the evaluation result of the user's dailyness with respect to the spot. For example, if staying at the spot is everyday for the user, select content that leads the user extraordinarily, and if staying at the spot is unusual for the user, Select content that leads to.

  Note that the content that guides the user extraordinarily is, for example, content that is intimate to the user, and the content that guides the user to everyday is, for example, content that is highly intimate for the user. Specifically, the content information storage unit 122 stores the closeness of the user for the content in association with each content. For example, the user's intimacy is stored as content tag information. When it is evaluated that the user stays in the area or the spot is high in everydayness, the content selection unit 112 is associated with a low familiarity among the contents in the content information storage unit 122. Select content. On the other hand, when it is evaluated that the user staying in the area or the spot is less usual for the user, the content selection unit 112 is associated with a high familiarity among the contents in the content information storage unit 122. Selected content.

  In addition, when it is determined that the user is staying at a spot in the area, the dailyness evaluation unit 110 evaluates both the user's dailyness with respect to the area and the user's dailyness with respect to the spot. If it is determined that the user is staying at a place other than the spot, the user's everydayness with respect to the area is evaluated. That is, when the user is located in a place where the area and the spot overlap, the dailyness is evaluated for both the area and the spot. When the user is located in a place where the area and the spot do not overlap, only the area is evaluated. Evaluate everydayness.

  When the content selection unit 112 determines that the user is staying at a spot in the area, the content selection unit 112 selects content based on the evaluation result of the user's daily level for the area, and the user's daily level for the spot. The content is selected based on the evaluation result. That is, when the user is located at a place where the area and the spot overlap, the content is selected according to the everydayness of the area and the content is selected according to the everydayness of the spot.

  On the other hand, when it is determined that the user is staying at a place other than the spot in the area, the content selection unit 112 selects the content based on the evaluation result of the user's dailyness with respect to the area. That is, when the user is located in a place where the area and the spot do not overlap, the content is selected only by the ordinary degree of the area.

  The dailyness information storage unit 124 (dailyness database) stores the dailyness in association with the area or spot where the user stays. For example, for each of a plurality of staying places where the user has stayed in the past, the corresponding ordinary degree is stored in association with each other. Specifically, when the frequency of the user's past stay experience with respect to the area or spot is high, a high level of everydayness is associated with the area or spot. On the other hand, when the frequency of the user's past stay experience with respect to the area or spot is low, a low ordinary degree is associated with the area or spot.

  The dailyness information storage unit 124 may store the dailyness in association with not only the user's staying place but also the user's staying place and staying time zone. For example, for each combination of a stay place and a stay time zone, a corresponding ordinary degree may be stored in association with each other.

  Then, the dailyness evaluation unit 110 reads out the dailyness associated with the area or spot where the user stays from the dailyness information storage unit 124 to evaluate the dailyness of the user. For example, the everydayness associated as tag information of each area or each spot is read, and the everydayness about staying in the area or spot is evaluated.

  Note that the dailyness is a parameter indicating the degree to which the user's current situation is normal (normal, common, mediocre), for example, in comparison with the user's past situation (situation history). It is. Also, the process for evaluating the user's daily level and the process for evaluating the extraordinary level (unusual, abnormal level) can be treated as equivalent processes.

  The presentation control unit 118 performs control for presenting the selected content to the user by the information presentation unit 142. For example, when the information presentation unit 142 is a wearable display or a digital photo frame, control is performed to present (display) the selected content (content image) from the wearable display or the digital photo frame.

3. Spots and Areas Now, in order to provide appropriate and timely content to the user, the user's position is specified using a GPS sensor or the like, and the content is selected and presented based on the specified position. Is desirable.

  However, the position data (latitude / longitude) obtained by the GPS sensor is merely data per se, and does not directly mean the place where the user stays. For this reason, it is necessary to extract a place meaningful to the user from these position data.

  For example, if the user's whereabouts are categorized based on the staying time, a place meaningful to the user can be extracted. In FIG. 3, a user who got off a station in a city such as Shinjuku walked around the station and stayed at a department store A, a crepe store B, a movie theater C, a family restaurant D, a general store E, and a bookstore F at each time zone. A heat map is shown as an example. If a GPS sensor or the like is used, the distribution of the user's position at each staying place can be known, and the size and concentration (density) of this distribution vary depending on the staying place. In this heat map, the place where the stay time is long is dark, and the places accompanied by the movement in the place are distributed over a wide range.

  As is apparent from FIG. 3, in a city such as Shinjuku, for example, there are a plurality of locations (for example, department store A, crepe store B, movie theater C, etc.) having different meanings for the user. Therefore, in the case of FIG. 3, it is not possible to present content that is really meaningful to the user simply by specifying that the user stays in Shinjuku and selecting and presenting content related to Shinjuku. That is, when the user is staying at the department store A, floor information and bargain information of each floor of the department store A should be presented. When the user is staying at the crepe shop B, the crepe shop B Recommended crepe information should be presented. Further, when the user stays in the movie theater C, the movie show time information and the hall information should be presented. However, if the user can only specify that he / she is in Shinjuku, such timely information according to the place where the user stays cannot be provided.

  On the other hand, for places visited for the purpose of taking a walk without staying at a specific place for a long time, such as a sightseeing spot, a meaningful place cannot be extracted in a narrow area. For example, when the user visits Mt. Takao, it is considered that the user strolls around various places on Mt. Takao, so the user's movement range is not a narrow range as shown in FIG. 3 but a wide range. Therefore, if the user's stay range is narrowed down as shown in FIG. 3, it cannot be extracted that the user is visiting Mt. Takao, and content related to Mt. There is a problem that it cannot be done.

  Therefore, in this embodiment, as shown in FIGS. 4A and 4B, the concept of area and spot is introduced as a place where the user stays. As shown in FIG. 4A, the area is an area wider than the spot, and as shown in FIG. 4B, for example, a spot narrower than the area exists in each area. In the present embodiment, such spots and areas are extracted by the method described below.

  For example, the area is an area where the standard deviation σ of the position within the predetermined period T1 is equal to or less than the first threshold value Sth1 (several hundreds to 1000 m). On the other hand, the spot is a region where the standard deviation σ of the position within the predetermined period T2 is equal to or less than a second threshold value Sth2 (for example, several tens to 100 m). In this embodiment, an area and a spot are extracted by statistically processing information of a position detection sensor such as a GPS sensor worn by the user. That is, based on the standard deviation σ of the user's position within a predetermined time, it is determined whether the user is staying in the area or spot.

  Specifically, it is assumed that the average of latitude and longitude in a predetermined period T1 (for example, 4 hours) is (Nμ, Eμ) and the standard deviation is (Nσ, Eσ). In this case, by converting (Nσ, Eσ) into distances and extracting regions where the standard deviations of the north-south and east-west distances are each Sth1 (for example, 1 km) or less, as shown in FIG. An area that is meaningful to the user can be extracted. On the other hand, by making the distance threshold as small as Sth = Sth2 (for example, several tens of meters) and performing the same processing as described above, spot extraction as shown in FIG. 4B becomes possible.

  Thus, in this embodiment, whether or not the user stays in the area based on whether or not the standard deviation σ of the user's position within the predetermined period T1 is equal to or less than the first threshold value Sth1. Determine whether. On the other hand, the user stays in the spot based on whether or not the standard deviation σ of the user's position within the predetermined period T2 is equal to or smaller than the second threshold value Sth2 that is smaller than the first threshold value Sth1. It will be judged whether or not.

  For example, at time t, statistical processing is performed on the position (latitude / longitude) of the user from time (t−T1) to time t to obtain the standard deviation σ of the position. If the standard deviation σ at that time is equal to or smaller than the first threshold value sth1, the user can determine that he / she has stayed in the area during the time period (t−T1) to t. Similarly, statistical processing is performed on the position of the user from time (t−T2) to time t to obtain the standard deviation σ of the position. If the standard deviation σ at that time is equal to or smaller than the second threshold value sth2, the user can determine that he / she stayed at the spot during the time period (t−T2) to t. It may be T1 = T2. In addition, the extraction of areas and spots may be realized by observing the position of a single user over a long period of time and processing it statistically, or by observing the positions of a large number of users and statistically processing them. It may be realized by processing.

  In the present embodiment, the width of each area of the plurality of areas is variably set, and the width of each spot of the plurality of spots is variably set. This can be realized by variably setting the first threshold value Sth1 for each area and variably setting the second threshold value Sth2 for each spot.

  For example, as shown in FIG. 5, each spot and each area are characterized by a distance range that is the size of the spot or area and an average stay time. Accordingly, by appropriately setting the distance range and the staying time, it is possible to classify the characteristics of spots and areas to some extent. That is, since the granularity (section) of the meaning area differs depending on the place and the genre, such genre division is effective for content selection based on the place where the user stays. For example, in FIG. 5, a coffee shop has a distance range (spot size) of about 10 m and a staying time of about 30 minutes, and a movie theater has the same distance range of about 10 m, but the staying time is about 2 hours. And longer than a coffee shop. In addition, the general store has a longer distance range than the coffee shop, which is about 100 m, and the staying time is about 30 minutes, while the shopping mall has a longer staying time, which is about 4 hours. Further, the area has a longer distance range (the area becomes wider) and the staying time is relatively longer than the spot. Thus, by appropriately setting the distance range (spot, area size) and staying time, it is possible to extract the meaning of the place that cannot be extracted only by the position data.

  For example, in FIG. 5, if Sth2, which is the threshold value of the spot, is set to about several meters to several tens of meters, spots such as coffee shops, family restaurants, movie theaters, offices, homes, convenience stores, etc. can be extracted. On the other hand, if the threshold value Sth2 is set to about several tens to 100 meters, spots such as general stores, department stores, shopping malls can be extracted, and if the threshold value Sth2 is further increased, spots of amusement facilities such as amusement parks are extracted. it can.

  If the threshold value Sth1 of the area is set to about 1 km to 10 km, areas such as Kichijoji and Shibuya can be extracted, and if the threshold value Sth1 is further increased, a larger area such as Mt. Takao can be extracted. .

  If the threshold values Sth1 and Sth2 are set variably in this way, the width of each area or each spot can be set variably. As a result, a place meaningful to the user can be appropriately extracted from the position data of the user.

4). Processing Example Next, a processing example of the present embodiment will be described using the flowcharts of FIGS. 6 and 7.

  First, sensor information from a behavior sensor, a state sensor, and an environment sensor is acquired (step S1). Then, based on the acquired sensor information, schedule information, external information, and the like, the user's situation (TPOF) such as the user's staying place is estimated (step S2).

  Next, it is determined whether or not the user is staying at the spot (step S3). If it is determined that the user is staying at the spot, the content for the spot where the user is staying is selected from the contents that are candidates for presentation (step S4). Then, the selected content is presented to the user by the information presentation unit 142 such as a wearable display (step S7).

  On the other hand, if it is not determined that the user is staying at the spot, it is determined whether or not the user is staying in the area (step S5). That is, it is determined whether the user is staying at a place other than the spot in the area. If it is determined that the user is staying in the area, the content for the area where the user is staying is selected from the contents that are candidates for presentation (step S6). Then, the selected content is presented to the user by the information presentation unit 142 (step S7).

  As shown in FIG. 6, when it is determined that the user is staying at a spot in the area (step S3), the spot content is preferentially selected (step S4), and the user is in the area. When it is determined that the user is staying at a place other than the spot (step S5), the area content is selected (step S6). That is, when the spot where the user stays is specified, the content related to the spot is selected, and when the spot where the user stays is not specified, the content related to the area is selected for the first time.

  FIG. 7 is a flowchart showing a specific example of the user staying location specifying process.

  First, the position of the user is specified based on information from a GPS sensor or the like (step S11). Then, the standard deviation σ of the user's position within the predetermined period is obtained (step S12).

  Next, it is determined whether or not the standard deviation σ is equal to or less than a spot threshold value Sth2 (step S13). If the standard deviation σ is equal to or smaller than Sth2, it is determined that the user stays at the spot (step S14). On the other hand, when the standard deviation σ is larger than Sth2, it is determined whether or not the standard deviation σ is equal to or smaller than the area threshold value Sth1 (step S15). If the standard deviation σ is equal to or smaller than Sth1, it is determined that the user is staying in the area (step S16).

5. Specific Example of Content Presentation FIGS. 8 and 9 show specific examples of content presented based on areas and spots. 8 and 9, the user situation (event) is determined based on the sensor information or the like, and it is determined whether or not the user is staying in an area or a spot. Then, the area content or the spot content is selected.

  FIG. 8 is an example of content presented when the user goes to Kichijoji from his home in the A street. For example, when it is determined that the user is at a spot at home in the area of street A, a weather forecast as home content is displayed on, for example, a wearable display. When it is determined that the user goes out and is in a place other than his home in the A street, the content of local news related to the A street is displayed.

  Next, when the user moves to the vicinity of the spot at station A, the train timetable corresponding to station A is displayed on the wearable display. When the user arrives at the A station, the transfer guidance that is the content associated with the A station is displayed. Thus, in each spot, content related to each spot is presented.

  Next, when the user moves to the area of D Street by train, contents about the famous spots of D Street and recommended spots are displayed. When the user approaches the spot of D station and arrives, a D station guide such as an introduction of “Echinaka” such as a famous cake shop is displayed.

  Next, when the user moves toward the area of Kichijoji, recommended spots of Kichijoji are displayed. A Kichijoji station guide is displayed near the spot of Kichijoji, and when you arrive at Kichijoji station, you will see recommended information such as recommended spots and meal guides.

  Next, when the user leaves the spot at Kichijoji Station, a map of Kichijoji and recommended spots are displayed. And in the vicinity of the spot of the G bookstore in the Kichijoji area, G bookstore information (events, introduction of hot selling books, etc.) is displayed, and in the vicinity of the spot of the E department store, E department store information (events, bargains, etc.) is displayed. . When the user arrives at the E department store, a floor guide for the E department store is displayed. As described above, contents corresponding to each area and each spot are displayed.

  FIG. 9 is an example of content presented when a user goes out to Mt. Takao from his home in A street.

  As shown in FIG. 9, at home, a weather forecast for confirming today's weather is displayed, and content indicating a seasonal flower or the like is displayed when the user leaves the home. When you drop in at a convenience store, advertisements for healthy drinks sold at convenience stores are displayed, and content related to each is displayed at stations A and B.

  As you approach the spot at Takao Yamaguchi Station, a guide to Takao Yamaguchi Station is displayed, and when you arrive at Takao Yamaguchi Station, content that informs you of mountain climbing preparations such as lunch purchase, toilet, and course introduction is displayed. When mountain climbing is started after leaving Takao Yamaguchi Station, a mountain climbing course guide that is content related to the Mt. Takao area is displayed.

  Next, when the user approaches the observatory, guidance for the observatory is displayed, and when the user arrives at the observatory, a guide for the scenery seen from the observatory is displayed. Then, away from the viewing platform, where there is no spot, content related to the Mt. Takao area such as seasonal flowers and wild birds is displayed.

  Next, at Yakuoin and a store, corresponding contents are displayed, and in the vicinity of the summit, the user is encouraged and the remaining distance to the summit is displayed. At the summit, information on the summit and scenery, and information on the amount of exercise and time required for climbing are displayed. Information about Shimoyama is also displayed.

  As described above, in FIGS. 8 and 9, when the user stays at a spot in the area, the content for the spot is presented, and when the user stays at a place other than the spot in the area, Are presented.

  Further, in the vicinity of the spot, for example, information for arousing interest in the spot is presented, and in the spot, for example, information for supporting activities in the spot is presented. If none of these is the case, information related to the area (map) that is likely to be of interest to the user is presented. 8 and 9 show examples of content presented at each timing (time), and other content is also presented as appropriate.

6). In the above, an example in which content is directly selected based on the area or spot where the user stays has been described. However, the everyday degree is evaluated based on the area or spot where the user stays. Content may be selected based on the evaluation result. FIG. 10 shows a flowchart of a processing example in this case.

  First, sensor information from a behavior sensor or the like is acquired, and a user's situation such as a staying place is estimated (steps S21 and S22). If it is determined that the user is staying at the spot, the user's everydayness about the spot is evaluated (steps S23 and S24). In other words, the daily degree of the user staying at the spot is obtained from the past stay history or the like. Then, the content is selected based on the evaluation result of the ordinary degree of the spot, and the selected content is presented by the information presentation unit 142 (steps S25 and S29).

  On the other hand, if the user is not staying at the spot, it is determined whether or not the user is staying in the area (step S26). If it is determined that the user is staying in the area, the user's everydayness for the area is evaluated (step S27). That is, the degree of everydayness about the user staying in the area is obtained from the past stay history and the like. Then, the content is selected based on the evaluation result of the ordinary degree for the area, and the selected content is presented by the information presentation unit 142 (steps S28 and S29).

  For example, when the spot or area where the user is staying has a high degree of everydayness for the user, in order to guide the user extraordinarily, the content with low intimacy for the user is selected and presented. On the other hand, when the spot or area is less common for the user, in order to reassure or support the user, content that is close to the user is selected and presented.

  For example, suppose that it is specified that the user is staying at a company spot during the daytime on weekdays. The situation in such a spot is an ordinary situation, and it is evaluated that the daily life of the user is high. Therefore, content that guides the user extraordinarily is presented. Specifically, when presenting the contents of lunch guidance to such a user, guidance information of a store that does not usually go or a store that has not been entered is presented.

  Further, for example, it is assumed that it is specified that the user is staying in an area of a foreign tourist spot that is visited for the first time during the daytime on a holiday. The situation in such an area is different from the usual situation, and it is evaluated that the ordinary degree of the user is low and that it is unusual. Therefore, the content for reassuring or supporting the user is presented. More specifically, when presenting lunch guidance content to such a user, information on fast food stores and chain stores that are usually used in Japan is presented.

  In addition, when evaluating everydayness, it is desirable to evaluate each of 5W1H (Who, What, When, Where, Why, How). For example, if the user is in the office on weekdays, it is evaluated that the ordinary degree is high. On the other hand, if the user is in the company on a holiday, it is evaluated that the ordinary degree is low. That is, even if the place is the same, if the time and date are different, the evaluation result of the ordinary degree will be different. Therefore, when evaluating the ordinary degree, the evaluation process of the ordinary degree can be made appropriate by evaluating not only the staying place of the user but also the combination of the staying place and the staying time zone. .

  When the user is staying at a spot in the area, the user evaluates both the everydayness of the area and the everydayness of the spot, selects the content based on the everydayness of the area, and selects the content based on the everydayness of the spot. Select. On the other hand, when the user is staying at a place other than the spot in the area, only the user's everyday level with respect to the area is evaluated, and the content is selected based on the daily level with respect to the area.

  For example, in FIG. 11, it is specified that the user is staying at the spot of the department store H1 in the Shinjuku area. In this case, both the everydayness of staying at the spot of the department store H1 and the everydayness of staying in the Shinjuku area are evaluated.

  In the case of FIG. 11, the content is selected based on the ordinary degree with respect to the spot of the department store H1, and the content is selected based on the ordinary degree with respect to the Shinjuku area.

  For example, it is assumed that the department store H1 is a spot that the user has visited for the first time, and is a spot that is less common for the user. In this case, in order to support a user in an extraordinary situation, the department store sales information as shown in FIG. 12A is presented. In this way, even if the user visits a department store for the first time, the user can easily find a sales floor for the desired product.

  On the other hand, it is assumed that the department store H1 is a spot that the user always visits and is a spot with a high degree of everydayness for the user. In this case, in order to guide the user extraordinarily, the information on the hole in the department store, the sale information, etc. are presented.

  In addition, it is assumed that the area of Shinjuku is an area that the user usually visits and is an area that is highly common for the user. In this case, content that leads the user to extraordinary is presented. Specifically, as shown in FIG. 12 (B), a display indicating that a store of a category different from usual (a store having high freshness for the user) is provided as a store visiting on the way back from the department store H1. In this way, it is possible to create a new awareness, discovery, and excitement by creating an opportunity to change the daily life that somehow behaves without thinking, and accepting this and experiencing new experiences by the user. Can be expected.

  On the other hand, it is assumed that the area of Shinjuku is an area that the user visits for the first time and is an area that is less common for the user. In this case, for example, guidance information on the way back from Department Store H to Shinjuku Station is displayed. In this way, it is possible to give a sense of security to a user who is in an uneasy situation rather than everyday.

  For example, it is assumed that the user is in the Shinjuku area but has not stayed at any of the spots A1, B1, C1, D1, E1, F1, and G1 in the Shinjuku area. In this case, content related to the Shinjuku area, such as Shinjuku road guidance and sight-seeing guidance, is selected and displayed.

  In this way, if the user's dailyness is evaluated separately for each spot or area and the content is selected, the user can select an appropriate content according to the dailyness for each spot or each area. It is possible to provide a content presentation system that is highly convenient for the user.

  In the above description, the method for selecting content based on the user's everydayness with respect to a spot or area has been described. However, the method of the present embodiment is not limited to this. For example, the dailyness obtained for a spot or area can be used for other purposes than content selection. For example, the content obtained for the spot or area may be recorded in the information storage unit in association with other information such as media information.

  For example, when shooting with a digital camera or the like, the user's everyday level is obtained for a spot or area that is a shooting location, and the determined daily level is recorded in association with a captured image that is media information. In this way, when the captured image is played back, the captured image is searched based on the everyday level associated with the captured image, or the captured image is deleted or organized based on the daily level. It becomes possible. For example, preferentially play back images shot at spots or areas with a low degree of everydayness, delete shot images at spots or areas with a high degree of everydayness, transfer them to an external media information storage unit, etc. Is possible.

  In the present embodiment, since the method of performing the evaluation of the ordinary degree for the area and the evaluation of the ordinary degree for the spot is adopted separately, there is an advantage that a more appropriate evaluation process of the ordinary degree can be realized.

  For example, in Shinjuku, where the user's office building is located, if the dailyness is judged in a wide area such as an area, the user can distinguish whether the user is at the office building or a hotel near the office. I can't. That is, a plurality of places having different meanings are mixed in the area, and there is a possibility that the evaluation of dailyness becomes inaccurate.

  On the other hand, with respect to places that are visited for the purpose of taking a walk without staying at a specific place for a long time, such as a sightseeing spot area, in a narrow area such as a spot, it is impossible to extract a meaningful place and it is impossible to evaluate the degree of daily life There is a fear.

  In this regard, in the present embodiment, it is determined whether the user is staying in the area or a spot in the area, and if the user is staying in the area, the daily life of the user about the area is determined. If you are staying at a spot, you are looking for the degree of everydayness about the spot. Therefore, since a region having a different meaning for the user can be cut out as a spot narrower than the area and the dailyness can be evaluated, a more accurate and appropriate dailyness evaluation process can be realized. Also, even when a meaningful place cannot be extracted in a narrow area such as a spot, an area having a different meaning for the user is cut out as an area wider than the spot, and the ordinaryness can be evaluated.

  In addition, various processes can be considered for the dailyness evaluation process. For example, the user's daily life at a staying place such as an area or a spot may be evaluated based on the existence probability of the user at the staying place.

  For example, in FIG. 13, at home, the existence probability of a user at noon on weekdays is low, but the existence probability at morning and evening on weekdays is high. In addition, the existence probability increases to some extent during the daytime of holidays, and the existence probability further increases in the morning and evening of holidays.

  On the other hand, in offices where employees work, the probability of existence is high on weekday noon, but the probability of existence is small on weekday mornings and evenings. In addition, a holiday office has a low existence probability both in the daytime and in the morning and evening.

  As shown in FIG. 14 (A), the existence probability obtained in FIG. 13 can be assigned to the everydayness N (value that is a calculation base of the everydayness). The ordinary degree may be calculated by taking into consideration the situation and emotions to such existence probability.

  In addition, for example, the ratio of the staying time in each area and each spot can be normalized by the average staying time of the place, and the dailyness of the user with respect to the place can be evaluated. In this way, it is possible to prevent a situation in which the dailyness of a place such as a convenience store that originally has a short stay time is calculated to be low.

  Alternatively, as shown in FIG. 14B, based on the number of times a user has existed in the spot area (number of times of entry) during a predetermined period (eg, 1-3 months), not based on the presence probability based on the stay time. The daily probability N may be calculated by defining the existence probability.

  The daily life information storage unit 124 (daily life database) can be realized by a combination of FIGS. 13 and 14A or a combination of FIGS. 13 and 14B. For example, the everydayness information storage unit 124 stores the everydayness as shown in FIGS. 14A and 14B in association with the user's staying place such as the area or spot of FIG. Alternatively, the ordinary degree is stored in association with the staying place of the user such as an area or a spot and the staying hours such as weekday noon, weekday morning / night, holiday noon, holiday morning / night. When a staying place such as a user's area or spot is specified, or in addition to this, a staying time zone such as a weekday daytime or a weekday morning / night time is specified, FIG. 13, FIG. 14A or FIG. 13 and FIG. ), The ordinary degree of the user can be evaluated by reading out the ordinary degree from the ordinary degree information storage unit 124.

7). Details of Spots and Areas Next, the meanings of spots and areas will be described in more detail. For example, FIG. 15 shows areas such as Mt. Takao, D street, E street, F street, G street, Kichijoji, and spots in these areas. Here, conventionally, a place having a certain size and the same meaning is treated as a “point”. For example, the location of Mt. Takao in FIG. 15 is associated with the latitude and longitude of the summit of Mt. Takao as position data, so the whole area where people who go on vacation to Mt. Takao take a walk cannot be treated as Mt. It was. Therefore, even if the user tries to present information about Mt. Takao when he approaches Mt. Takao, only the method of presenting at a timing when the user approaches a predetermined distance from the summit set as the position of Mt. .

  In this case, an appropriate predetermined distance may be 5 km for Mt. Takao, for example, but it may vary to 100 m for a department store in Shibuya. Also, the walking area is not necessarily circular, and if it is Mt. Takao, it will be distributed along the mountain trail, so inconvenience will arise if it is uniformly 5 km from the summit.

  Therefore, in the present embodiment, a method is adopted in which the location is treated as a single region based on the stay time and distribution of many users (users) who visit the location. Furthermore, this area is divided into a hierarchy of areas and spots, and areas that are visited for specific purposes are spots, and areas that are wide areas such as towns and sightseeing spots that are visited for higher purposes are areas. Information can be presented.

  Specifically, a spot is a relatively small area where you will stay for some time for a specific purpose, such as shopping or watching a movie. Specific examples of the spot include a coffee shop, a department store, a movie theater, and Kiyomizu Temple.

  On the other hand, an area is an area including a plurality of spots suitable for a certain purpose, such as a city or a sightseeing spot, and the user exists in the area for a certain period of time while moving to inquire about those spots. It is a relatively wide area that will do. Alternatively, it is a relatively wide area that does not include a specific spot, such as a resort area, and will exist within that area for some time while moving for the purpose of walking. Specific examples of areas include Kichijoji, Shibuya, Kyoto, and Mt. Takao.

  In the present embodiment, the attribute of the place where the user currently stays is described as both the area and spot attributes, and appropriate content is presented according to each attribute. For example, if the area where the user stays is Shibuya and the spot is a department store L, the content related to Shibuya and the content related to the department store L are candidates for presentation content to the user. Then, when providing lunch guidance to the user, contents recommending a restaurant in the department store L that suits the user's preference, a restaurant popular in Shibuya, and the like are presented.

  For example, if the user is moving in the gap between spots while walking around the city, only the attributes of the area can be described, and at that time, only the content related to the area becomes the presentation content candidate. On the other hand, if the location is a spot but not an area, only the content related to the spot is a presentation content candidate.

  Detailed information about the spot (for example, department store sales information) may be presented after the user enters the spot, but recommended information about the spot (for example, department store bargain information, etc.) It is preferable to present it when heading to the spot. The same applies to the area.

  For example, in FIGS. 16A and 16B, when a user enters a predetermined area including a spot called coffee shop I (in the circle with a predetermined radius in the figure), as shown in FIG.
