Description

This disclosure relates to an information processing device or the like that controls changing the display state of displayed information.

In the technology for operating information processing devices, there are known information processing devices that change the display state of information displayed on the screen.

An example of an information processing device is described in Patent Document 1. The cursor control device described in Patent Document 1 includes a trackball mouse. Display control means causes display means to display data from a partial area within a data storage area. When the cursor is moved to the edge of the screen in response to operation of the trackball mouse, an image indicating the location of the displayed partial area within the entire data storage area is displayed at the cursor display position by the display control means.

Furthermore, the aerial survey system described in Patent Document 2 displays survey data as two-dimensional and three-dimensional images, and displays images at different altitudes by operating an input unit including a trackball or detecting eye movements.

Japanese Patent Application Laid-Open No. 2002-049454 JP 2012-047866 A

There is a demand for switching the method of changing the display state of information on a display screen in response to mouse or other device operations. For example, a user may operate the mouse to move the image display area and display images for different times on the screen. As an example, let's consider a case where a user references weather maps displayed on a screen, viewing weather maps for multiple regions, multiple times, and multiple altitudes. Generally, on a screen displaying a weather map, the displayed area is changed by dragging the cursor using a pointing device such as a trackball mouse. On the other hand, when changing the display to a weather map for a different time or altitude, a menu with multiple sliders or buttons must be displayed on the screen to display images for different altitudes or times. This requires a display area for the sliders or buttons on the screen, which reduces the display area for the weather map image and reduces visibility. Furthermore, when changing the display state, the user must move the cursor over the display area of the slider or menu displayed on the screen and change the display state while operating the slider or multiple buttons on the menu.

As such, when changing the display state of information, a display area is required to display multiple sliders or menus with multiple buttons for on-screen operation, posing the problem of reduced visibility. Furthermore, after moving the cursor to a display area such as a slider or menu, i.e., a specific area on the screen, it becomes necessary to operate the cursor within that specific area, posing the problem of reduced operability.

Patent Document 1 does not disclose the above-mentioned problem, nor does it describe a means for solving the problem. Patent Document 2 discloses displaying two-dimensional and three-dimensional images and changing the display state to images of different heights, but does not disclose the specific operation of the input unit for this purpose. Therefore, Patent Document 2 also does not disclose the above-mentioned problem or a means for solving the problem.

The present disclosure aims to solve the above problems and provide an information processing device or the like that can improve the visibility of the screen display and the operability of changing the display state.

An information processing device according to one aspect of the present disclosure includes a detection means for detecting input from an input unit in a first operation mode for changing the display state of information displayed on a screen, and a control means for switching the operation mode from the first operation mode to a second operation mode in response to a predetermined event, and for controlling the display state of the information in response to the detection of the input in the second operation mode.

An information processing method according to one aspect of the present disclosure detects input from an input unit in a first operation mode for changing the display state of information displayed on a screen, switches the operation mode from the first operation mode to a second operation mode in response to a predetermined event, and controls the display state of the information in response to the detection of the input in the second operation mode.

An information processing program according to one aspect of the present disclosure causes a computer to execute the following processes: detecting input from an input unit in a first operation mode for changing the display state of information displayed on a screen; switching the operation mode from the first operation mode to a second operation mode in response to a predetermined event; and controlling the display state of the information in response to the detection of the input in the second operation mode.

One of the effects of this invention is that it improves the operability of operations to change the display state. Furthermore, since there is no need to display buttons, sliders, etc. on the screen to change the display state, the visibility of the display area can be improved.

Next, the embodiment will be described in detail with reference to the drawings.

[First embodiment]
Fig. 1 is a block diagram showing the configuration of an information processing device 100 according to the first embodiment. Referring to Fig. 1, the information processing device 100 includes a detection unit 101 and a control unit 102. The input unit 103 may be located within the information processing device 100, or may be separate from the information processing device 100 and connected to the information processing device 100 via wired or wireless communication so as to be able to communicate with the information processing device 100.

Next, the configuration of the information processing device 100 in the first embodiment will be described in detail.

The detection unit 101 detects input from the input unit 103 to change the display state of information displayed on the screen.

The control unit 102 controls the display state of information displayed on the screen in response to the input detected by the detection unit 101. The information whose display state is controlled may be information stored within the device or information received via wired or wireless communication. Hereinafter, the setting that combines the input via the input unit 103 and the control of the display state performed in response to the input will be referred to as the operation mode.

The input unit 103 is, for example, a trackball mouse, touch panel, camera, etc., and is used by the user to make inputs. For example, a camera can be used as the input unit 103, and the detection unit 101 can detect eye movement from the camera, and the control unit 102 can use information representing the eye movement as input to control changing the display state of the information displayed on the screen. Alternatively, if a camera is used as the input unit 103, the detection unit 101 can detect finger movement from an image of the finger movement.

Next, the control unit 102 will be described. For example, a case will be described in which a mouse is used as the input unit 103. A cursor indicating the mouse operation point is displayed on the screen of a display (not shown), and an operation for selecting an object (operation A) is performed by clicking a button, icon, or the like on the screen. An operation for moving an object or display area by dragging and dropping (operation B) is also performed, and an operation for scrolling or zooming in and out of the screen (operation C) is performed by rotating the mouse wheel upward or downward with a finger (moving the mouse wheel up or down). Alternatively, the display state of information displayed on the screen may be changed by operating various menu buttons or sliders (operation D). Such operation control using operations A to D is referred to as the first operation mode. Of course, the first operation mode is not limited to operation control using operations A to D. Furthermore, the operation in the first operation mode is not limited to operation using a mouse, and may also be the aforementioned operation mode using non-contact input or an operation mode using a touch panel, etc.

When a predetermined event occurs, the control unit 102 switches the operation mode from the first operation mode to the second operation mode and controls the display state of information displayed on the screen in response to detection of an input in the second operation mode. The detection of an input is detection by the detection unit 101.

The specified event may be, for example, selecting an operation mode switching button displayed in a small area on the screen. In this case, it may be possible to switch between the first operation mode and the second operation mode each time the operation mode switching button is selected. Alternatively, the specified event may be selecting a menu for switching the operation mode from a pop-up menu that is temporarily displayed by right-clicking the mouse. The specified event may also be, but is not limited to, detecting that the cursor is over the information whose display state you want to change, or that the information whose display state you want to change is displayed.

The second operation mode can perform operation control that is partially or completely different from the operation control performed in the first operation mode. For example, the control unit 102 performs control to change the display state of information in response to input detected by the detection unit 101, and the control unit 102 sets the control content for the first operation mode and the second operation mode, respectively. In the second operation mode, the control unit 102 performs control to change the display state without displaying a menu with multiple sliders or buttons for changing the display state on the screen. Furthermore, one or more display state changes can be set for input from the input unit 103. For example, when the detection unit 101 detects input of moving the trackball of a trackball mouse used as the input unit 103 up or down, the control unit 102 controls the display of information with a first variable of the information displayed on the screen changed. Alternatively, when the detection unit 101 detects input of moving the trackball left or right, the control unit 102 controls the display of information with a second variable of the information displayed on the screen changed. The first variable may be, for example, the altitude of the weather chart to be displayed, and the second variable may be, for example, the time of day of the weather chart to be displayed, and may be set according to the information to be displayed.

Furthermore, the operation modes are not limited to the first operation mode and the second operation mode, but three or more operation modes may be set.

The operation of the information processing device 100 configured as described above will be explained with reference to the flowchart in Figure 2.

Figure 2 is a flowchart showing an overview of the operation of changing the display state of information displayed on the screen of the information processing device 100 in the first embodiment. Note that the processing according to this flowchart may be executed based on program control by the CPU of the hardware that constitutes the information processing device 100.

As shown in FIG. 2, first, the control unit 102 detects that a predetermined event has occurred that switches the operation mode from the first operation mode to the second operation mode (step S101).

Next, the control unit 102 changes the operation mode from the first operation mode to the second operation mode (step S102).

Next, the detection unit 101 detects input from the input unit 103 (step S103).

Next, the control unit 102 controls the change of the predetermined display state set as the second operation mode in response to the input detected by the detection unit 101 (step S104).

As an example of steps S103 and S104, we will explain a case where the display state of the weather map is controlled in the second operation mode in response to input detected by the detection unit 101. In step S103, when the user uses a trackball mouse as the input unit 103 and rotates the trackball of the trackball mouse upward (hereinafter referred to as moving the trackball up), the detection unit 101 detects the input resulting from that operation. Also, when the user rotates the trackball of the trackball mouse downward (hereinafter referred to as moving the trackball down), the detection unit 101 detects the input resulting from that operation. In step S104, the control unit 102 controls the display state of the weather map in response to the input detected by the detection unit 101 in the second operation mode. In this case, the altitude of the weather map is increased in response to the operation of moving the trackball up, and the altitude of the weather map is decreased in response to the operation of moving the trackball down, thereby changing the display state so that a weather map showing the weather conditions at the altitude corresponding to the movement of the trackball is displayed. Note that this control by the control unit 102 is merely an example and is not limited to this.

Furthermore, the switching of the operation mode between steps S101 and S102 may be performed multiple times, and the input and control of steps S103 and S104 may also be repeated. This makes it possible to set three or more operation modes, rather than limiting the operation modes to the first and second operation modes.

This completes the operation of the information processing device 100 to change the display state of the information displayed on the screen.

Next, we will explain the effects of the first embodiment of the present disclosure.

In the information processing device of this embodiment described above, the control unit 102 switches the operation mode from the first operation mode to the second operation mode in response to a predetermined event, and controls the change of the display state in the second operation mode in response to input detection. Therefore, in the second operation mode, it is possible to set operations that are not possible in the first operation mode. For example, it is possible to change the display state using only the movement of the trackball, i.e., to display a weather map showing weather conditions at an altitude corresponding to the movement of the trackball, or a weather map showing weather conditions at a time corresponding to the movement of the trackball. As a result, the user no longer needs to input using menus with multiple sliders or buttons, thereby improving operability. Furthermore, since there is no need for a display area on the screen to display menus with multiple sliders or buttons for changing the display state of information, the information display area can be expanded, improving visibility.

Second Embodiment
Next, a second embodiment of the present disclosure will be described in detail with reference to the drawings. Below, the description of the second embodiment will be omitted to the extent that it does not make the description of the present embodiment unclear.

In the second embodiment, as a specific example of the present disclosure, a case will be described in which the information to be displayed on the screen and the display state of which is changed is a weather map. In this embodiment, the weather map is information that can display multiple weather maps showing weather conditions at different altitudes and multiple weather maps showing weather conditions at different times, i.e., weather maps for each past and present point in time and forecast weather maps for each future point in time. This information may be generated internally by the control unit 102, or may be obtained from a weather database (not shown).

Figure 3 is a block diagram showing the configuration of an information processing device 200 according to the second embodiment of the present disclosure.

Referring to FIG. 3, compared to that of the first embodiment, the information processing device 200 of this embodiment includes a detection unit 201 instead of the detection unit 101, a control unit instead of the control unit 202, a trackball mouse 203 instead of the input unit 103, and further includes a display unit 204. The trackball mouse 203 and the display unit 204 may be located within the information processing device 200, or may exist separately from the information processing device 200 and be communicatively connected to the information processing device 200 via wired or wireless communication.

The detection unit 201 detects input from the trackball mouse 203.

The control unit 202 switches the operation mode in response to a predetermined event. Furthermore, the display state of the weather map is changed according to the operation mode in response to input from the trackball mouse 203 detected by the detection unit 201. An event that triggers switching of the operation mode is, for example, the control unit 202 detecting that a weather map has been displayed by a website or app. When the predetermined event is detected, the control unit 202 switches the operation mode from the first operation mode to the second operation mode. Alternatively, the predetermined event may be the detection by the detection unit 201 that an input has been made to display the weather map, and the control unit 202 determining this detection.

Furthermore, when the detection unit 201 detects that the specified event is, for example, right-clicking the trackball mouse 203 to display a context menu and selecting to switch the operation mode, the control unit 202 switches the operation mode. If the operation mode before the switch was the first operation mode, it may be switched to the second operation mode, and if the operation mode before the switch was the second operation mode, it may be switched to the first operation mode. Furthermore, when the detection unit 201 detects that a selection to end the display of the weather map has been made, for example by right-clicking the trackball mouse 203 to display a context menu, the control unit 202 may end the display of the weather map and switch the operation mode from the second operation mode to the first operation mode.

Next, examples of the first and second operation modes in this embodiment will be described with reference to Figure 4. Note that the correspondence between inputs in the first and second operation modes and changes to the display state is not limited to the contents of Figure 4.

In the first operation mode of this embodiment, the control unit 202 controls changes to the display state based on the control reference data shown in FIG. 4. First, when the detection unit 201 detects a drag input on the map, the control unit 202 changes the latitude and longitude of the display area of the weather map in the direction of the drag. Furthermore, when the detection unit 201 detects an input to move the mouse wheel up or down, the control unit 202 changes the display state to a weather map enlarged by a predetermined magnification corresponding to the amount of rotation of the mouse wheel. Furthermore, when the detection unit 201 detects an input to operate a button or slider displayed on the screen displaying the weather map to change the altitude of the displayed weather map, the control unit 202 changes the display state to a weather map showing weather conditions at a different altitude in the same display area as the currently displayed weather map. Similarly, when the detection unit 201 detects an input to operate a button or slider displayed on the screen to change the displayed time, the control unit 202 changes the display state to a weather map showing weather conditions at a different time, i.e., a past weather map or a future forecast weather map, in the same display area as the currently displayed weather map.

In the second operation mode, the control unit 202 also controls changes to the display state based on the control reference data shown in Figure 4. Mouse drag inputs and mouse wheel inputs, and the changes to the display state, are the same as in the first operation mode in this example, and therefore will not be described here. In the second operation mode, first, the trackball is moved up or down to change the display state to a weather map with a changed altitude. When the detection unit 201 detects an input moving the trackball up, the control unit 202 changes the display state to a weather map with the altitude increased by a predetermined amount according to the amount of rotation of the trackball. Similarly, when the detection unit 201 detects an input moving the trackball down, the control unit 202 changes the display state to a weather map with the altitude decreased by a predetermined amount according to the amount of rotation of the trackball. Next, the trackball is moved left or right to change the display state to a weather map with the time changed. When the detection unit 201 detects an input moving the trackball left, the control unit 202 changes the display state to a past weather map with the time reversed by a predetermined amount according to the amount of rotation of the trackball. Similarly, when the detection unit 201 detects an input moving the trackball to the right, the control unit 202 changes the display state to a future weather forecast map with the time advanced by a predetermined amount according to the amount of rotation of the trackball. This second operation mode is one example, and the above-mentioned content is not limiting; for example, the altitude of the weather map may be lowered according to an input moving the trackball up, and the altitude of the displayed weather map may be raised according to an input moving the trackball down. In addition, the user may be able to change the control reference data for the operation mode according to their own preferences.

The above explains how to set the correspondence between inputs in the first and second operation modes and changes to the display state when the information to be displayed is a weather map and a trackball mouse is used as the input device.

The second operation mode can be set by changing the information to be displayed and the input unit, and the correspondence between the input in the second operation mode and the changes to the display state can be changed as needed. For example, when the information to be displayed is a weather map and a touch panel is used as the input unit, instead of input by moving a trackball mouse up and down or left and right, the detection unit 201 can detect input by moving two fingers up and down or left and right on the touch panel, and the display state can be changed to a weather map with a different predetermined altitude or time depending on the input. Also, for example, when the information to be displayed is a screen for editing images and videos, the brightness of the images and videos to be edited can be set to change by moving a trackball mouse up and down or two fingers up and down on the touch panel.

Next, the operation of the information processing device 200 will be described with reference to the flowchart shown in Figure 5.

As shown in FIG. 5, first, the control unit 202 detects the display of a weather chart as a predetermined event for switching the operation mode (step S201). Note that the predetermined event may be at least one of the events described above.

Next, the control unit 202 changes the operation mode from the first operation mode to the second operation mode (step S202).

Next, the detection unit 201 detects input from the trackball mouse 203 (step S203).

Next, the control unit 202 performs control to make a predetermined change to the display state of the weather chart set in the second operation mode in response to the input detected by the detection unit 201 (step S204).

This completes the operation of the information processing device 200 to change the display state of the weather chart.

Next, we will explain the effects of the second embodiment of the present disclosure.

In the information processing device of this embodiment described above, the control unit 202 switches the operation mode from the first operation mode to the second operation mode in response to a predetermined event, and controls the change of the display state in the second operation mode in response to input detection. Therefore, in the second operation mode, it is possible to set operations that are not possible in the first operation mode. For example, it is possible to change the display state using only the movement of the trackball, i.e., to display a weather map showing weather conditions at an altitude corresponding to the movement of the trackball, or a weather map showing weather conditions at a time corresponding to the movement of the trackball. As a result, the user does not need to input using a menu with multiple sliders or buttons, thereby improving operability. Furthermore, since there is no need for a display area on the screen to display a menu with multiple sliders or buttons for changing the display state of information, the information display area can be expanded, improving visibility.
