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, portable terminals using a touch panel as an input device have become widespread. The touch panel is an input device that combines a display device such as an LCD (Liquid Crystal Display) and an input device such as a touch pad. An operation using a touch panel is often preferred to an operation using buttons because an intuitive and complicated operation is unnecessary.

  In recent mobile terminals, a touch panel is often disposed on substantially the entire front surface of the mobile terminal in order to make 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 touches the touch panel. For example, some portable terminals perform processing that does not accept input from the part touched at the second place when two or more places are touched at the same time in order to prevent erroneous operation. If the hand on the side holding the mobile terminal is in contact with the touch panel, the input by the hand on the operating side will not be recognized. On the other hand, if the hand is held so that it does not touch the touch panel, the handheld terminal becomes unstable and may cause a drop.

  As a method for solving this problem, Patent Document 1 discloses that the function assigned to the touched area is executed and the touch panel is touched when the touched time of the touch panel has not reached a predetermined time. A method is described in which the processing is not executed when the predetermined 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 touches the touch panel for a longer time than the contact by the normal operation. From this, by using the method described in Patent Document 1, erroneous operation of the touch panel can be reduced.

  Further, in Patent Document 2, a grip position in the longitudinal direction of the mobile terminal is detected by 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. Describes a method for facilitating an operation by a grasping hand by displaying on a touch panel.

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 accepts input by touch. As the touch panel 51, a capacitive touch panel 51 or the like that enables multipoint detection is used.
A plurality of menu icons are displayed on the touch panel 51 as an initial screen of the mobile terminal 5.

  A plurality of sensors 52-1 to 52-6 (hereinafter, the 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 contact by gripping by the user, and outputs a voltage indicating ON when the user is in contact and a voltage indicating OFF when the user is not in contact.

FIG. 2 is a schematic block diagram of the portable terminal 5 according to the first embodiment of the present invention.
Although not shown in FIG. 1, the portable terminal 5 has a computer system inside. Then, when the computer system reads and executes a program stored in a computer-readable recording medium, an application execution unit 501, a touch input detection unit 502, a grip detection unit 503, a user determination unit 504, an invalid area specifying 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 means 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 the 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 touches the touch panel 51 and a contact area that is a coordinate area on the touch panel 51 where the user and the touch panel 51 are in contact.
The grip detection unit 503 detects whether or not the terminal is gripped from the output of the sensor 52.
The user discriminating 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 detection unit 502 as an invalid area when the application execution 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 acquired by the user determining 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 determining 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 displays the contact area detected by the touch input detection unit 502 as 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 an invalid area is set.
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 application execution unit 501 starts to execute the invalid area setting application, the application execution unit 501 outputs a display command of a message that prompts the user to hold the terminal, such as “Please hold in hand”. As shown in FIG. 4A, the display control unit 509 causes the touch panel 51 to display the message acquired from the application execution unit 501 (step S1). FIG. 4 is a diagram showing how invalid areas are set.

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

  On the other hand, when the grip detection unit 503 detects that the terminal itself is gripped (step S2: YES), the grip detection unit 503 outputs a signal indicating that the grip is detected by the invalid area specifying unit 505 and the user determination unit 504. 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. To do. In addition, when receiving a signal from the grip detection unit 503, the user determination unit 504 acquires the ON / OFF information of each sensor 52 as user identification information (step S4), and the identification information is stored in the recording unit 507. Output.

The recording unit 507 determines whether or not 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 S5).
Specifically, the recording unit 507 determines whether the ON / OFF matches for each sensor 52, and if the number of mismatches is equal to or less than a predetermined threshold (for example, one), the storage unit 506 It is determined that the identification information to be stored is the same as or close to the identification information received from the user determination unit 504.

When the recording unit 507 determines that 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 (step S5: NO), the invalid area specifying unit The invalid area specified by 505 and the identification information received from the user determination unit 504 are associated and recorded in the storage unit 506 (step S6).
On the other hand, if the recording unit 507 determines that 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 S5: YES), the storage unit 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 to the display control unit 509 a command for displaying a message indicating the end of recording of the invalid area, such as “registration completed”. As shown in FIG. 4B, the display control unit 509 displays the message acquired from the application execution unit 501 on the touch panel 51 (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 invalid area setting is completed by executing the invalid area setting application and an input request is made by the application executed by the application execution unit 501, the touch input detection unit 502 determines whether or not the user touches the touch panel 51. Determination is made (step S11). When the touch input detection unit 502 determines that there is no contact with the touch panel 51 (step S11: NO), the touch input detection unit 502 returns to step S11 and continues the determination process until a contact 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 terminal is gripped by the user (step S12). When the grip detection unit 503 determines that the terminal is gripped (step S12: YES), the user determination unit 504 acquires ON / OFF information of each sensor 52 as user identification information (step S12). S13), the identification information is output to the input unit 508.

The input unit 508 determines whether 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 is the same as or similar to the identification information received from the user determination unit 504 (step S14: YES), from the storage unit 506. The invalid area associated with the identification information is read out. 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 range as an input, returns to step S11, and returns to the touch panel 51. Judgment of contact is made.

  On the other hand, if it is determined in step S12 that the terminal is not gripped, none of the identification information stored in the storage unit 506 in step S14 is the same as or similar to the identification information received from the user determination unit 504. (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).

  Thus, according to this embodiment, even if a user contacts the area previously recorded as the invalid area, the mobile terminal 5 does not regard the contact as an input. Thereby, regardless of the contact time with the touch panel 51, an erroneous operation can be prevented by the hand holding the mobile terminal 5 coming into contact with the touch panel 51.

  Further, according to the present embodiment, the input unit 508 determines whether or not the contact area is included in the invalid area when the grip detection unit 503 detects gripping of the terminal itself. Thereby, when the portable terminal 5 is not gripped, contact with 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. As a result, the input unit 508 can determine the input for each user using the invalid area that matches the user. In this embodiment, the case where the 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 is received from the user and the information is used as the identification information. You can also. However, it is more efficient to use the ON / OFF information as the identification information, as in this embodiment, because the identification information input process can be omitted.

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.
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 the 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 showing the operation of the mobile terminal 5 according to the second embodiment after setting the invalid area.

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

  The inscribed rectangle calculation unit 510 determines whether or not 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). When the inscribed rectangle calculation unit 510 determines that 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: YES), the storage is performed. The invalid area associated with the identification information is read from the unit 506.

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 that is not an invalid area in the touch panel 51 (step S24). Next, the inscribed rectangle calculation unit 510 calculates the coordinates (for example, the upper left coordinates) and the 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 shown 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 the 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 directly displays the display image received from the application execution unit 501 to the display control unit 509. The display control unit 509 outputs the display image on the touch panel 51 (step S29).
