부분적으로 감지영역을 활성화하는 터치스크린 단말기Touch screen terminal to partially activate the detection area
본 발명은 부분적으로 감지영역을 활성화하는 터치스크린 단말기에 관한 것으로서, 보다 상세하게는 정전용량 전극채널이 형성된 단말기에 자기력 센서를 설치하고, 자기력 펜이 터치스크린에 접근하면 자기력 펜이 위치한 영역만 활성화하여 접촉을 감지하도록 하는 부분적으로 감지영역을 활성화하는 터치스크린 단말기에 관한 것이다.The present invention relates to a touch screen terminal that partially activates a sensing area. More particularly, a magnetic force sensor is installed in a terminal on which a capacitive electrode channel is formed, and when a magnetic pen approaches a touch screen, only a region in which a magnetic pen is located is activated. The present invention relates to a touch screen terminal that partially activates a sensing area for sensing a contact.
터치 디스플레이는 마우스와 키보드 등의 입력장치를 대체할 수 있는 입력방식으로서, PDA, LCD, CRT, 은행, 관공서, 각종 의료장비, 관광 및 주요 기관의 안내, 교통안내 등 다양한 분야에서 적용되고 있다.The touch display is an input method that can replace an input device such as a mouse and a keyboard, and is applied in various fields such as PDA, LCD, CRT, banks, government offices, various medical equipments, tourism and major organizations, and traffic guidance.
도 1은 종래기술에 따른 터치 감지를 무효화하는 방법을 나타낸 개념도이다.1 is a conceptual diagram illustrating a method of invalidating touch sensing according to the prior art.
종래기술의 디바이스는 사용자로부터 터치 형태의 사용자 신호를 입력받고, 사용자 신호에 대응되는 처리결과를 디스플레이를 통해 출력한다. 디바이스의 입력수단과 출력수단은 물리적으로 동일한 공간에 형성되는 패널 형태의 터치 디스플레이다.The prior art device receives a user signal in the form of a touch from a user and outputs a processing result corresponding to the user signal through a display. The input means and output means of the device are panel-type touch displays formed in the same physical space.
터치 디스플레이가 풀 스크린 형태임에 따라 사용자 터치 신호를 입력받을 수 있는 영역은 증가하지만, 자연히 터치 가능한 면적이 증가하게 되고, 활성화 영역을 제외한 영역 중에 디바이스를 파지 또는 그립할 수 있는 면적인 배젤 영역은 줄어들게 된다. 따라서 이전에는 사용자가 디바이스 사용시에 터치용도가 아닌 그립 또는 파지 동작에서 발생하지 않던 터치이슈가 발생하게 된다. 예를 들어, 사용자는 단순히 디바이스를 그립할려고 했으나, 의도하지 않게 배젤 영역을 벗어나 활성화 영역을 터치하게 될 수 있다. 이때, 디바이스가 사용자의 원래 의도와는 상관없는 터치동작으로 인해 다른 동작을 수행하게 된다.As the touch display is in the form of a full screen, an area in which a user touch signal can be input increases, but an area in which touch is naturally increased increases, and an area of the bezel area in which the device can be gripped or gripped is excluded. Will be reduced. Therefore, a touch issue that has not occurred in a grip or grip operation that is not a touch purpose when a user uses the device occurs. For example, a user may simply want to grip the device, but may inadvertently leave the bezel area and touch the activation area. In this case, the device performs another operation due to a touch operation irrelevant to the user's original intention.
도 1의 9-1은 디바이스의 세로 모드에서 사용자의 부주의한 파지의 한 예를 도시한 것이고, 9-2 및 9-3은 가로 모드에서 사용자의 부주의한 파지의 예를 도시한 것이다.9-1 of FIG. 1 shows an example of careless gripping of a user in a portrait mode of a device, and 9-2 and 9-3 illustrate examples of careless gripping of a user in a landscape mode.
사용자의 손가락이나 손바닥의 접촉으로 인해 부주의한 터치 이벤트가 발생하고 있는 중에 사용자가 실제로 원하는 터치 이벤트를 수행하고 하는 경우에 해당 터치 이벤트는 처리되지 못하여, 디바이스가 잠금되는 것과 같은 현상이 생긴다.If a user actually performs a desired touch event while an inadvertent touch event occurs due to a touch of a user's finger or palm, the touch event is not processed and a device is locked.
이를 해결하기 위해 터치 디스플레이의 일정 영역을 비활성화시켜 터치를 감지하지 못하도록 하기도 하는데, 이럴 경우에는 비활성화된 영역에 글을 쓰거나 터치를 하기 위해서 비활성 영역을 매번 수정해야 하는 불편함이 있었다.In order to solve this problem, some areas of the touch display may be deactivated so that a touch cannot be detected. In this case, it is inconvenient to modify the inactive area every time in order to write or touch on the deactivated area.

It is an object of the present invention to provide a touch screen terminal which partially activates a sensing area.
또한 본 발명은 자기력 펜의 동작을 자기력 센서가 인식하여 특정 동작이 이루어지면 특정 입력모드로 변경되도록 하여 다양한 효과를 낼 수 있도록 하는 부분적으로 감지영역을 활성화하는 터치스크린 단말기를 제공하는 것을 목적으로 한다.In addition, an object of the present invention is to provide a touch screen terminal that partially activates the sensing area to recognize the operation of the magnetic pen by the magnetic force sensor to change to a specific input mode when a specific operation is made to produce a variety of effects. .

그리고 본 발명의 터치단말기(100)에는 자기력 센서(110)가 설치된다. 자기력 센서(110)는 자기장의 변화(세기, 방향 등)를 감지하여 자기장 발생장치의 위치나 이동방향, 속도 등을 파악하는 수단으로서, 자기력 디지타이저 장치에 사용되는 구성과 유사하다. 본 발명의 도면에서는 직사각형인 터치스크린(104)의 네 군데 모서리 부근에 네 개의 자기력 센서(110)가 각각 설치되는 것으로 도시하지만, 자기력 센서(110)는 한 개 또는 두 개 이상 자유롭게 설치할 수 있다.The magnetic force sensor 110 is installed in the touch terminal 100 of the present invention. The magnetic force sensor 110 is a means for detecting a change in the magnetic field (strength, direction, etc.) to grasp the position, the moving direction, the speed, and the like of the magnetic field generator, and is similar to the configuration used in the magnetic force digitizer device. In the drawings of the present invention, four magnetic force sensors 110 are respectively installed near four corners of the rectangular touch screen 104, but one or more magnetic force sensors 110 may be freely installed.
제어부(112)는 전극채널(106, 108)이나 자기력 센서(110)가 감지하는 신호를 분석하여 적절한 동작명령을 각 구성부품에 전달한다.The controller 112 analyzes a signal sensed by the electrode channels 106 and 108 or the magnetic force sensor 110 and transmits an appropriate operation command to each component.
한편, 사용자가 자기장 발생기능이 있는 자기력 펜(200)을 손에 쥐고 터치스크린(104) 위에서 글자를 쓰거나 그림을 그리면, 자기력 펜(200)을 쥐고 있는 손의 손가락이나 손바닥이 터치스크린(104)의 표면에 닿으면서 오작동을 일으킬 수 있다. 본 발명의 상세한 설명이나 도면에서는 자기력 펜(200)의 위치가 아닌 오작동을 일으킬 수 있는 접촉이 일어나는 부분을 '접촉영역'이라고 정의한다. 도 3과 같이 손의 접촉에 의해 접촉영역이 발생하과, 이로 인해 사용자가 의도하지 않았던 신호의 입력이 발생한다.On the other hand, when a user holds a magnetic pen 200 having a magnetic field generating function in his hand and writes letters or draws on the touch screen 104, the finger or palm of the hand holding the magnetic pen 200 is touch screen 104. It may cause a malfunction by touching the surface of the camera. In the detailed description or drawings of the present invention, a portion in which contact occurs that may cause a malfunction instead of the position of the magnetic pen 200 is defined as a 'contact area'. As shown in FIG. 3, a contact area is generated by the touch of a hand, and thus a signal input that is not intended by the user is generated.
본 발명에서는 접촉영역의 신호로 인한 오작동이 일어나지 않도록 사용자가 잡고 있는 자기력 펜(200)의 주위에만 감지영역(120)을 형성한다. 본 발명에서 설명하는 '감지영역'은 전극채널(106, 108)이 신호의 입력을 유효하게 감지할 수 있는 영역을 말하며, 감지영역(120)의 바깥에서 일어나는 접촉신호는 제어부(112)가 무시하도록 설정된다. 따라서 감지영역(120)이 아닌 곳에서 일어나는 손가락이나 손바닥의 접촉 신호는 제어부(112)에 의해 무시된다.In the present invention, the sensing region 120 is formed only around the magnetic force pen 200 held by the user so that a malfunction due to the signal of the contact region does not occur. The 'sensing area' described in the present invention refers to an area in which the electrode channels 106 and 108 can effectively detect a signal input, and the control unit 112 ignores a contact signal occurring outside the sensing area 120. Is set to. Therefore, the contact signal of the finger or the palm occurring in the non-sensing area 120 is ignored by the controller 112.
도 5에 도시된 바와 같이, 사용자가 자기력 펜(200)을 잡고 터치스크린(104)에 접근시키면, 자기력 센서(110)는 자기장의 세기나 방향 등을 고려하여 자기력 펜(200)의 위치를 파악한다. 그리고 파악된 위치에 자기력 펜(200)이 있는 것으로 가정하고, 그 주위의 일정한 면적의 영역을 감지영역(120)으로 설정한다. 이후에는 감지영역(120) 안에서 이루어지는 접촉신호만을 유효한 신호로 간주하여 저장하고, 그 이외의 영역에서 이루어지는 접촉은 무효한 신호로 간주하여 무시한다. 따라서 감지영역(120) 이외의 영역에서 사용자가 손을 접촉시키거나 다른 펜을 접촉시켜도 터치단말기(100)에 입력되지 않는다.As shown in FIG. 5, when the user grabs the magnetic pen 200 and approaches the touch screen 104, the magnetic force sensor 110 determines the position of the magnetic pen 200 in consideration of the strength or direction of the magnetic field. do. In addition, it is assumed that the magnetic force pen 200 is located at the identified position, and a region of a constant area around the magnetic force pen 200 is set as the sensing region 120. Thereafter, only the contact signal made in the sensing area 120 is regarded as a valid signal and stored, and the contact made in other areas is regarded as an invalid signal and ignored. Therefore, even if the user touches a hand or touches another pen in an area other than the sensing area 120, the touch terminal 100 is not input to the touch terminal 100.
만약 자기력을 발생시키지 않는 펜을 사용하는 경우에는 자기력 센서(110)가 펜의 위치를 파악할 수 없기 때문에 별도의 감지영역(120)을 형성하지 않는다.If a pen that does not generate magnetic force is used, the magnetic force sensor 110 does not form a separate sensing area 120 because the magnetic force sensor 110 cannot detect the position of the pen.
경우에 따라서는 특별한 조건에서만 감지영역(120)을 설정하도록 할 수도 있다. 가령, 자기력 펜(200)이 일정한 속도나 가속도 이상으로 움직이는 경우에만 감지영역(120)을 형성할 수도 있고, 다른 명령어와 함께 입력이 이루어진 때에만 감지영역(120)을 설정하도록 할 수도 있다. 바람직하게는 사용자가 미리 정해놓은 동작을 하면 자동으로 감지영역(120)이 설정되도록 하여 그 부분의 신호만 입력되도록 한다.In some cases, the sensing region 120 may be set only under special conditions. For example, the sensing region 120 may be formed only when the magnetic force pen 200 moves above a certain speed or acceleration, or the sensing region 120 may be set only when an input is made with other commands. Preferably, when the user performs a predetermined operation, the detection area 120 is automatically set so that only the signal of the part is input.
제어부(112)에 의해 형성되는 감지영역(120)의 모양이나 크기는 사용환경에 따라 다양하게 변화될 수 있다. 일반적으로는 자기력 펜(200)이 위치한 곳을 중심으로 하는 원형의 감지영역(120)을 설정하게 된다. 그러나 자기력 펜(200)이 기울어진 정도에 따라서 타원형이 되도록 하거나, 직사각형 모양으로 설정할 수도 있다.The shape or size of the sensing region 120 formed by the controller 112 may vary depending on the usage environment. In general, the circular sensing region 120 is set around the magnetic force pen 200. However, the magnetic pen 200 may be elliptical or set in a rectangular shape according to the degree of inclination.
한편, 사용자가 자기력 펜(200)을 움직이는 동작을 감지하여 특정 입력모드를 확인하는 방법을 추가로 적용할 수도 있다. 예를 들어 자기력 펜(200)을 원형이나 8자로 회전하면, 펜 설정을 연필에서 붓으로 바꾼다거나 할 수 있다. 자기력 센서(110)는 자기력 펜(200)위치와 이동방향 등을 파악할 수 있기 때문에 미리 설정된 방식의 움직임에 따라 입력모드를 변경하도록 제어할 수 있다.Meanwhile, a method of detecting a specific input mode by detecting a motion of the user moving the magnetic pen 200 may be further applied. For example, if the magnetic force pen 200 is rotated in a circle or eight characters, the pen setting can be changed from a pencil to a brush. Since the magnetic force sensor 110 may grasp the position and the moving direction of the magnetic force pen 200, the magnetic force sensor 110 may control to change the input mode according to a movement of a preset method.
또한 자기력 펜(200)을 기울인 정도에 따라 자기장의 세기나 방향이 달라진다. 자기력 센서(110)는 기울어진 정도를 감지하고, 제어부(112)는 기울어진 정도에 따라 입력되는 글자나 그림의 굵기를 변화시킨다. 예를 들어 자기력 펜(200)이 많이 기울어진 상태에서 글자를 쓴다면, 입력되는 글자의 굵기를 크게 변화시킨다. 이로 인해 마치 사용자가 실제 연필을 기울여서 쓰면서 굵기가 달라지는 것과 유사한 효과를 낼 수 있을 것이다.In addition, the strength or direction of the magnetic field varies depending on the degree of inclination of the magnetic force pen 200. The magnetic force sensor 110 detects the degree of inclination, and the control unit 112 changes the thickness of an input letter or a picture according to the degree of inclination. For example, if the magnetic pen 200 is written in a state inclined a lot, the thickness of the input letter is greatly changed. This will produce a similar effect as if the user tilted the actual pencil while writing.
