(Embodiment 1)
Hereinafter, Embodiment 1 will be described with reference to FIGS.
[1-1. Constitution]
FIG. 1 is a diagram illustrating an appearance of the information processing apparatus according to the first embodiment. The information processing apparatus 100 performs predetermined information processing based on an OS (Operating System). In this embodiment, an example in which a notebook computer is applied as an example of an information processing apparatus is shown.

  In FIG. 1, the information processing apparatus 100 includes a housing 110, a keyboard 120, an input / output terminal 130, a touch pad 140, and a touch pad button 150. Hereinafter, each component will be described.

  The keyboard 120 accepts key input from a user of the information processing apparatus 100. The keyboard 120 is disposed on the housing 110.

  An external input device is connected to the input / output terminal 130. The external input device accepts various inputs from the user of the information processing apparatus 100. In this embodiment, a USB (registered trademark) port is used as an example of an input / output terminal. A simple interface may be used.

  The touch pad 140 receives an operation by contact from a user of the information processing apparatus 100.

  The touch pad button 150 transmits various commands to the information processing apparatus 100 by receiving an input from a user of the information processing apparatus 100. The touch pad button 150 is used as an assist for a touch operation by the touch pad 140.

FIG. 2 is an enlarged view of the touch pad 140 and the touch pad button 150 of the information processing apparatus according to the first embodiment. The touch pad 140 has a detection surface as a range for detecting physical coordinates input by the user. In a normal case, the detection surface of the touch pad 140 is an area that occupies almost the entire area of the touch pad 140. When an external input device is connected, the detection surface of the touch pad 140 is limited. The feature region 210 is a region that continues to be a detection surface even when the detection surface is limited. The other area 220 is an area in which input from the user is invalidated when the effective area of the touch pad 140 is limited. In the present disclosure, the other region 220 is formed at the outer edge of the detection surface. In the present disclosure, the range occupied by the other area 220 in the direction in which the keyboard 120 exists (upward in FIG. 2) from the center of the touch pad 140 indicated by the alternate long and short dash line is away from the keyboard 120 from the center of the touch pad ( Wider than the area occupied by
FIG. 3 is a block diagram of the information processing apparatus according to the first embodiment.

  The processor 310 controls other components of the information processing apparatus 100 by executing a program.

  The storage device 320 temporarily or permanently stores data necessary for the processing of the information processing device 100. For example, the storage device 320 stores the OS 325 and programs. As the storage device 320, a volatile memory, a non-volatile memory, a HDD (Hard Disk Drive), or the like is used.

  The bus 330 is a place through which electrical signals transmitted and received by other components of the information processing apparatus 100 pass. Control signals and data are transmitted and received between the components of the information processing apparatus 100 via the bus 330.

  The touch pad controller 340 converts the touched coordinates into a format processed by the processor 310 in response to a touch from the user. The coordinates are converted into a format having a structure such as (X, Y).

  The external input / output device controller 350 is electrically connected to the input / output terminal 130. The external input / output device controller 350 can acquire information related to the connection state of the external input device. The information regarding the connection state includes information regarding the presence / absence of connection. The external input device in the present disclosure refers to a coordinate indicating device that indicates coordinates, such as a mouse or a touchpad.

The processor 310 calculates designated coordinates managed on the OS 325 based on the coordinate history acquired by the external input device and / or the touchpad controller 340. To calculate the instruction coordinates managed on the OS 325 based on the external input device is, for example, when the mouse is connected, the instruction coordinates are calculated based on information obtained based on the movement of the mouse. is there. The processor 310 executes predetermined processing on each component of the information processing apparatus 100 via a program stored in the storage device 320.
[1-2. Operation]
The operation of the information processing apparatus 100 configured as described above will be described.

  FIG. 4 is a flowchart illustrating operations performed by the information processing apparatus according to the first embodiment.

  Each process in the flowchart shown in FIG. 4 is executed by the processor 310.

  Step S400 is started by a pressing event. The press event is an event that the processor 310 recognizes through the touch pad controller 340 that contact has been detected on the detection surface of the touch pad 140. As an example of a specific method for causing the information processing apparatus 100 to recognize the start of a pressing event, there is a method in which the processor 310 acquires the coordinates via the bus 330 every time the touchpad controller 340 acquires the coordinates. As another method, the processor 310 may detect contact based on data obtained from the touchpad controller 340 by using a program (API) prepared by the OS 325.

  In step S <b> 410, the processor 310 confirms whether a coordinate pointing device is connected to the external input / output device controller 350 using a program prepared in the OS 325. If a coordinate pointing device is connected, the process proceeds to step S420. If the coordinate pointing device is not connected, the process proceeds to step S470.

  In step S420, the coordinates acquired by the touchpad controller 340 are stored in the storage device 320.

  In step S430, the processor 310 determines whether or not the coordinates stored in the storage device 320 are coordinates on the feature area 210. Specifically, the processor 310 determines whether or not the coordinates (X, Y) stored in the storage device 320 exist in the coordinate group (X1... Xn, Y1... Yn) occupied by the feature area 210. To do. If the stored coordinates are on the feature area 210, the process proceeds to step S440. If the stored coordinates are not coordinates on the feature area 210 (coordinates on the other area 220), the process proceeds to S460.

  In step S440, processor 310 validates inputs for feature region 210 and other regions 220.

  In step S450, the processor 310 validates the input for the feature region 210 and invalidates the input for the other region 220. As an example of a method for invalidating the input, it is possible to hook the coordinate information acquired by the touchpad controller 340 so as not to transmit it to the OS 325. Here, the hook refers to blocking information transmission by interrupting information between the touchpad controller 340 and the OS 325.

  In step S460, processor 310 validates the input for feature region 210 and other regions 220.

In step S470, the processor 310 ends the process.
[1-3. Effect]
As described above, in the present embodiment, the information processing apparatus 100 according to the present disclosure includes the processor 310, the touch pad 140 that has a detection surface that detects physical coordinates input by the user, and the coordinate instruction that indicates the coordinates. An input / output terminal 130 to which the device is connected and a storage device 320 in which an OS 325 is recorded are included. The processor 310 calculates designated coordinates managed on the OS 325 based on the coordinates detected by the detection surface or the coordinates designated by the coordinate designating device. The processor 310 invalidates the input to a part of the area on the detection surface when the coordinate pointing device is connected.

  In this way, when the coordinate pointing device is connected, even if a part of the touch pad 140 is touched, the touch is not processed by the information processing device 100 as an input. Therefore, the user touches the touch pad 140 by mistake in a situation where the user connects and uses the coordinate pointing device, in other words, there is a high possibility that the touch pad 140 provided in the information processing apparatus 100 is not used. Can reduce the possibility of erroneous input.

  Further, in the information processing apparatus 100 of the present disclosure, the processor 310 invalidates input to the outer edge area on the detection surface when the coordinate pointing device is connected. That is, the other region 220 is formed on the outer edge of the detection surface.

  In this way, it is possible to invalidate only the detection surface of the touch pad 140 that is easily touched particularly when an erroneous input occurs. Therefore, even when the coordinate pointing device is connected, the portion near the center of the touch pad 140 (feature region 210) can be used, so that erroneous input can be prevented while maintaining user convenience. .

  In addition, the information processing apparatus 100 according to the present disclosure has a keyboard 120 at a location adjacent to the touch pad 140, and the direction in which the keyboard 120 exists from the center of the touch pad 140 in another area 220 where input on the detection surface is invalidated. Is wider than the range occupied in the direction away from the keyboard 120 from the center of the touch pad 140.

  By doing so, it is possible to invalidate only the detection surface of the touch pad 140 that is easily touched when erroneous input occurs. In general, a place where an erroneous input is likely to occur on the touch pad is an outer edge of the touch pad and a place near the keyboard. Therefore, even when the coordinate pointing device is connected, the lower portion (feature region 210) of the touch pad 140 can be used, so that it is possible to prevent erroneous input while maintaining user convenience. it can.

  Further, the information processing apparatus according to the present disclosure specifies that contact has been detected on the detection surface of the touchpad by a pressing event (S430). If the detected coordinates are outside a part of the area where the input on the detection surface becomes invalid, the processor 310 enables the input on the entire detection surface even when the coordinate pointing device is connected (S440).

  In this way, the possibility that an input that is not likely to be an erroneous input is determined to be an erroneous input is reduced. The feature region 210 that is the center of the touch pad 140 is likely to be touched by the user with will. If a drag operation is subsequently performed from the feature area 210, there is a high possibility of touching another area 220. In the present disclosure, in consideration of the possibility of continuous input from the feature region 210 to the other region 220 in this way, if contact is detected in the feature region 210 in the press event, the other region 220 is displayed. Do not disable it. Therefore, as long as the user does not remove his / her finger from the feature area 210, the user can continuously input to the other area 220.

  As described above, the embodiments have been described as examples of the technology in the present disclosure. For this purpose, the accompanying drawings and detailed description are provided.

  Accordingly, among the components described in the accompanying drawings and the detailed description, not only the components essential for solving the problem, but also the components not essential for solving the problem in order to illustrate the above technique.
