Description

  The present invention relates to a portable terminal that accepts an input operation by touching a touch panel, an invalid area specifying method, and a program.

  In recent years, mobile terminals using a touch panel as an input device have become widespread. The touch panel is an input device in which a display device such as an LCD (Liquid Crystal Display) and an input device such as a touch pad are combined. The operation using the touch panel is often preferred to the operation using the buttons because intuitive and complicated operations are not required.

  In recent mobile terminals, a touch panel is often provided on substantially the entire front surface of the mobile terminal in order to take a large screen. However, since the entire display screen of the touch panel is an input device, there is a possibility that an erroneous operation may be performed when a hand holding the mobile terminal contacts the touch panel. For example, in some portable terminals, for example, in order to prevent an erroneous operation, when two or more places are touched at the same time, a process that does not accept an input by a part touched at the second place is performed. If the hand holding the mobile terminal is in contact with the touch panel, input by the operating hand will not be recognized. On the other hand, if the hand is held so as not to touch the touch panel, the holding of the mobile terminal becomes unstable, which may cause a drop.

  As a method for solving this problem, Patent Literature 1 discloses that when the time of touching the touch panel does not reach a predetermined time, the function assigned to the touched area is executed and the touch panel is touched. A method is described in which the processing is not executed when the elapsed time reaches a predetermined time. When the hand holding the mobile terminal is in contact with the touch panel, it is predicted that the hand will be in contact with the touch panel for a longer time than the contact by a normal operation. Thus, by using the method described in Patent Document 1, erroneous operation of the touch panel can be reduced.

  Further, in Patent Document 2, a longitudinal grip position of the mobile terminal is detected based on detection outputs of a plurality of sensors provided in the mobile terminal, and the key display area is shifted in the longitudinal direction in accordance with the grip position. There is described a method of displaying an image on a touch panel to facilitate operation by a grasping hand.

However, the method described in Patent Literature 1 can be used for an input method by a short-time contact such as an input by a key touch, but can be applied to an input method such as a handwriting input, in which a contact time on a touch panel is long. There is a problem that can not be.
The present invention has been made in view of the above-described problem, and has as its object to prevent an erroneous operation by a hand holding a mobile terminal touching a touch panel regardless of a contact time with the touch panel.

  The present invention has been made to solve the above-described problems, and has a contact detection unit that detects a contact region of a touch panel, an identification information acquisition unit that acquires identification information, and a contact region that is detected by the contact detection unit. An invalid area specifying unit that specifies an invalid area that does not accept a user's input operation based on a recording unit that records the identification information and invalid area information indicating the invalid area in a storage unit in association with each other. And a portable terminal that rewrites the invalid area information associated with the identification information recorded in the storage unit to the specified invalid area information when the invalid area is specified by the invalid area specifying unit.

  The present invention also includes a step of detecting a contact area of the touch panel, a step of acquiring identification information, and a step of identifying an invalid area that does not accept a user's input operation based on the detected contact area; Recording the identification information in association with the invalid area information indicating the invalid area; and, when the invalid area is specified in the step of specifying the invalid area, the invalid area associated with the recorded identification information. Rewriting information with the specified invalid area information.

<< 1st Embodiment >>
Hereinafter, a first embodiment of the present invention will be described in detail with reference to the drawings.
FIG. 1 is an external view of a portable terminal 5 according to the first embodiment of the present invention.
The mobile terminal 5 is provided with a touch panel 51 on the front surface, which is a surface facing the user during use. The touch panel 51 includes a display device such as an LCD and an input device such as a touch pad, and displays a screen and receives an input by touch. As the touch panel 51, a touch panel that can perform multi-point detection, such as a capacitive touch panel 51, is used.
As the initial screen of the mobile terminal 5, a plurality of menu icons are displayed on the touch panel 51.

  A plurality of sensors 52-1 to 52-6 (hereinafter, sensors 52-1 to 52-6 are collectively referred to as sensors 52) are provided on the side surface and the back surface of the mobile terminal 5. The sensor 52 detects a contact caused by the user's grip, and outputs a voltage indicating ON when there is contact, and a voltage indicating OFF when there is no contact.

FIG. 2 is a schematic block diagram of the mobile terminal 5 according to the first embodiment of the present invention.
Although not shown in FIG. 1, the mobile terminal 5 has a computer system inside. Then, the computer system reads and executes the program stored in the computer-readable recording medium, whereby the application execution unit 501, the touch input detection unit 502, the grip detection unit 503, the user determination unit 504, the invalid area identification unit 505, a storage unit 506, a recording unit 507, an input unit 508, and a display control unit 509. Here, the computer-readable recording medium refers to a magnetic disk, a magneto-optical disk, a CD-ROM, a DVD-ROM, a semiconductor memory, or the like.

The application execution unit 501 executes an application program stored in a storage medium of the mobile terminal 5. The application program includes at least an invalid area setting application.
The touch input detection unit 502 detects whether or not the user has touched the touch panel 51 and detects a contact area that is a coordinate area on the touch panel 51 where the user has touched the touch panel 51.
The grip detection unit 503 detects whether or not the own terminal is gripped from the output of the sensor 52.
The user determination unit 504 acquires ON / OFF information of the sensor 52 as user identification information.

The invalid area specifying unit 505 specifies the contact area detected by the touch input detecting unit 502 as an invalid area when the application executing unit 501 executes the invalid area setting application.
The storage unit 506 stores the invalid area specified by the invalid area specifying unit 505 and the identification information obtained by the user determination unit 504 in association with each other.
When the invalid area specifying unit 505 specifies the invalid area, the recording unit 507 records the identification information acquired by the user determination unit 504 in the storage unit 506 in association with the invalid area specified by the invalid area specifying unit 505. .

When the contact area detected by the touch input detection unit 502 is not included in the invalid area stored in the storage unit 506, the input unit 508 converts the contact area detected by the touch input detection unit 502 into the application execution unit 501. Output to
The display control unit 509 receives a display image from the application execution unit 501 and causes the touch panel 51 to display the display image.

Next, the operation of the mobile terminal 5 according to the present embodiment will be described.
First, the operation of the mobile terminal 5 when setting the invalid area will be described. FIG. 3 is a flowchart showing the operation of the mobile terminal 5 according to the second embodiment when setting an invalid area.
When the menu icon indicating the invalid area setting application displayed on the touch panel 51 is touched, the application execution unit 501 executes the invalid area setting application. When the execution of the invalid area setting application is started, the application execution unit 501 outputs to the display control unit 509 a display instruction of a message that prompts the user to hold the terminal, such as “hold in hand”. The display control unit 509 causes the message acquired from the application execution unit 501 to be displayed on the touch panel 51 as shown in FIG. 4A (step S1). FIG. 4 is a diagram showing a state of setting an invalid area.

  When the display control unit 509 displays the message, the grip detection unit 503 determines whether the user has gripped the terminal (step S2). Specifically, the determination as to whether or not the grip has been made is made based on whether or not any of the sensors 52 outputs a voltage indicating ON. When the grip detection unit 503 determines that the own terminal is not gripped (step S2: NO), the process returns to step S2 and continues the determination process until the grip is detected.

  On the other hand, when the grip detection unit 503 detects that the own terminal is gripped (step S2: YES), the invalid area identification unit 505 and the user determination unit 504 output a signal indicating that the terminal is gripped. When receiving the signal from the grip detection unit 503, the invalid area specifying unit 505 acquires the contact area currently detected by the touch input detection unit 502 (Step S3), and outputs the contact area as an invalid area to the recording unit 507. I do. Further, upon receiving the signal from the grip detection unit 503, the user determination unit 504 acquires ON / OFF information of each sensor 52 as user identification information (step S4), and stores the identification information in the recording unit 507. Output.

  The recording unit 507 determines whether or not any of the identification information stored in the storage unit 506 is the same or similar to the identification information received from the user determination unit 504 (Step S5). Specifically, the recording unit 507 determines whether or not the ON / OFF matches for each sensor 52. If the number of unmatched ones is equal to or smaller than a predetermined threshold (for example, one), the storage unit 506 determines It is determined that the stored identification information is the same or similar to the identification information received from the user determination unit 504.

If the recording unit 507 determines that none of the identification information stored in the storage unit 506 is identical or similar to the identification information received from the user determination unit 504 (step S5: NO), the invalid area identification unit The invalid area specified by 505 and the identification information received from the user determination unit 504 are associated with each other and recorded in the storage unit 506 (step S6).
On the other hand, when the recording unit 507 determines that some of the identification information stored in the storage unit 506 is the same or similar to the identification information received from the user determination unit 504 (step S5: YES), the storage unit 507 506 rewrites the invalid area stored in association with the identification information to the invalid area specified by the invalid area specifying unit 505 (step S7).

  When the recording unit 507 records the invalid area, the application execution unit 501 outputs a display instruction of a message indicating the end of the invalid area recording, such as “registration completed”, to the display control unit 509. The display control unit 509 causes the message acquired from the application execution unit 501 to be displayed on the touch panel 51 as shown in FIG. 4B (step S8). Then, the application execution unit 501 ends the execution of the invalid area setting application.

Next, the operation of the mobile terminal 5 after setting the invalid area will be described. FIG. 5 is a flowchart showing the operation of the mobile terminal 5 according to the second embodiment after setting the invalid area.
When the setting of the invalid area is completed by executing the invalid area setting application and an input request is made by the application executed by the application executing unit 501, the touch input detecting unit 502 determines whether or not the user touches the touch panel 51. A determination is made (step S11). When the touch input detection unit 502 determines that there is no touch on the touch panel 51 (step S11: NO), the touch input detection unit 502 returns to step S11 and continues the determination process until the touch is detected. .

  On the other hand, when the touch input detection unit 502 determines that the touch panel 51 has been touched (step S11: YES), the touch input detection unit 502 outputs the coordinates of the contact area to the input unit 508. Next, the grip detection unit 503 determines whether or not the user's terminal is gripped by the user (step S12). When the grip detection unit 503 determines that the own terminal is gripped (step S12: YES), the user determination unit 504 acquires ON / OFF information of each sensor 52 as identification information of the user (step S12). S13), and outputs the identification information to the input unit 508.

The input unit 508 determines whether or not any of the identification information stored in the storage unit 506 is the same as or similar to the identification information received from the user determination unit 504 (Step S14). When the input unit 508 determines that the identification information stored in the storage unit 506 includes the same or similar identification information as the identification information received from the user determination unit 504 (step S14: YES), the input unit 508 returns to the storage unit 506. The invalid area associated with the identification information is read. Next, the input unit 508 determines whether or not the contact area received from the touch input detection unit 502 is included in the read invalid area (step S15).
When the input unit 508 determines that the contact area received from the touch input detection unit 502 is included in the read invalid area (step S15: YES), the input unit 508 does not treat the contact area as an input and returns to step S11 to the touch panel 51. Is determined.

  On the other hand, if it is determined in step S12 that the own terminal is not gripped, there is no identification information stored in the storage unit 506 that is the same as or similar to the identification information received from the user determination unit 504 in step S14. (Step S14: NO), or when it is determined that the contact area received from the touch input detection unit 502 is not included in the read invalid area (step S15: NO), the input unit 508 detects the touch input. The contact range received from the unit 502 is output to the application execution unit 501 (Step S16).

  As described above, according to the present embodiment, even if the user makes contact with an area recorded in advance as an invalid area, the portable terminal 5 does not regard the contact as an input. Thereby, regardless of the contact time with the touch panel 51, erroneous operation due to the hand holding the mobile terminal 5 touching the touch panel 51 can be prevented.

  Further, according to the present embodiment, when the grip detection unit 503 detects the grip of the own terminal, the input unit 508 determines whether the contact area is included in the invalid area. Thus, when the mobile terminal 5 is not held, the touch on the invalid area can be regarded as an input.

  Further, according to the present embodiment, the storage unit 506 stores an invalid area for each user in association with the identification information. Thus, the input unit 508 can determine an input for each user by using an invalid area that matches the user. In the present embodiment, the case where ON / OFF information of the sensor 52 is used as the identification information has been described. However, the present invention is not limited to this. For example, information such as a user ID may be received from a user and the information may be used as the identification information. Can also. However, when the ON / OFF information is used as the identification information as in the present embodiment, the input processing of the identification information can be omitted and the processing is more efficient.

The ratio calculation unit 511 calculates a ratio between the size of the rectangle calculated by the inscribed rectangle calculation unit 510 and the size of the touch panel 51.
The reduction unit 512 receives a display image to be displayed on the touch panel 51 from the application execution unit 501, and reduces the display image to a ratio calculated by the reduction ratio calculation unit.

Next, the operation of the mobile terminal 5 according to the present embodiment will be described.
The operation of the mobile terminal 5 when setting the invalid area is the same as that of the mobile terminal 5 according to the first embodiment. Therefore, here, the operation of the mobile terminal 5 after setting the invalid area will be described. FIG. 7 is a flowchart illustrating the operation of the mobile terminal 5 according to the second embodiment after setting the invalid area.

  When the setting of the invalid area is completed by executing the invalid area setting application, the grip and hold detection unit determines whether or not the user terminal is gripped by the user (step S21). When the grip detection unit 503 determines that the own terminal is gripped (step S21: YES), the user determination unit 504 acquires ON / OFF information of each sensor 52 as identification information of the user (step S21). S22), and outputs the identification information to the inscribed rectangle calculation unit 510.

  The inscribed rectangle calculation unit 510 determines whether or not any of the identification information stored in the storage unit 506 is the same as or similar to the identification information received from the user determination unit 504 (Step S23). If the inscribed rectangle calculation unit 510 determines that the identification information stored in the storage unit 506 includes the same or similar identification information as the identification information received from the user determination unit 504 (step S23: YES), the storage unit 510 stores the information. An invalid area associated with the identification information is read from the unit 506.

FIG. 8 is a diagram illustrating a state of reduction of a display image.
As shown in FIG. 7A, the inscribed rectangle calculation unit 510 generates a rectangle having the same aspect ratio as the touch panel 51 and inscribed in an area of the touch panel 51 that is not an invalid area (step S24). Next, the inscribed rectangle calculation unit 510 calculates coordinates (for example, upper left coordinates) and a size of the rectangle (step S25). Next, as shown in FIG. 7B, the ratio calculation unit 511 calculates the ratio between the size of the rectangle calculated by the inscribed rectangle calculation unit 510 and the size of the touch panel 51 (step S26). Then, as illustrated in FIG. 7C, the reduction unit 512 receives a display image to be displayed on the touch panel 51 from the application execution unit 501, and reduces the display image to a ratio calculated by the reduction ratio calculation unit (Step S27). ). Then, the display control unit 509 receives the reduced display image from the reduction unit 512, and displays the display image at the coordinates calculated by the inscribed rectangle calculation unit 510 (step S28).

  On the other hand, when the grip detection unit 503 determines in step S23 that the own terminal is not gripped (step S21: NO), the reduction unit 512 sends the display image received from the application execution unit 501 to the display control unit 509 as it is. Then, the display control unit 509 causes the display image to be displayed on the touch panel 51 (step S29).

  As described above, according to the present embodiment, the mobile terminal 5 can display the display image on the touch panel 51 so as not to overlap the invalid area. Thereby, the mobile terminal 5 can make the part which is normally hidden by the grasping hand visible to the user.
