JP6863441B2 - Mobile terminal, invalid area identification method and program - Google Patents

Description

The present invention relates to a mobile terminal that accepts an input operation by touching a touch panel, an invalid area identification 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 that combines a display device such as an LCD (Liquid Crystal Display) and an input device such as a touch pad. Touch panel operations are often preferred over button operations because they are intuitive and do not require complicated operations.

In recent years, mobile terminals often have a touch panel arranged 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 risk that an erroneous operation may be performed when the hand holding the mobile terminal comes into contact with the touch panel. For example, in some mobile terminals, for example, in order to prevent erroneous operation, when two or more places are touched at the same time, a process of not accepting input by the touched part at the second place is performed. If the hand holding the mobile terminal is in contact with the touch panel, the input by the operating hand will not be recognized. On the other hand, if the hand is gripped so as not to touch the touch panel, the grip of the mobile terminal becomes unstable, which may cause a fall.

As a method for solving this problem, in Patent Document 1, when the time of contact with the touch panel has not reached a predetermined time, the function assigned to the contacted area is executed and the touch panel is in contact with the touch panel. A method of not executing the process when the specified time is reached is described. 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. Therefore, by using the method described in Patent Document 1, it is possible to reduce erroneous operation of the touch panel.

Further, in Patent Document 2, the gripping position in the longitudinal direction of the mobile terminal is detected by the detection outputs of a plurality of sensors provided in the mobile terminal, and the key display area is shifted in the longitudinal direction according to the gripping position. , A method of facilitating the operation by the grasping hand by displaying it on the touch panel is described.

Japanese Unexamined Patent Publication No. 2011-039990 JP-A-2010-154090

However, although the method described in Patent Document 1 can be used as an input method by short-time contact such as input by key touch, it can be applied to an input method such as handwriting input in which the contact time with the touch panel is long. There is a problem that it cannot be done.
The present invention has been made in view of the above problems, and an object of the present invention is to prevent erroneous operation by contacting the touch panel with a hand holding a mobile terminal regardless of the contact time with the touch panel.

It has an application execution unit that executes an invalid area setting application for specifying the invalid area, and when an invalid area is specified during execution of the invalid area setting application, it is associated with the identification information recorded in the storage unit. It is a mobile terminal that rewrites the invalid area information into the specified invalid area information.

Further, the present invention includes a step of detecting a contact area of a touch panel, a step of acquiring identification information, and a step of specifying an invalid area that does not accept a user's input operation based on the detected contact area. The step of associating and recording the identification information with the invalid area information indicating the invalid area, the step of executing the invalid area setting application for specifying the invalid area, and the invalid area being specified during the execution of the invalid area setting application. If this is the case, it is an invalid area identification method including a step of rewriting the invalid area information associated with the recorded identification information into the specified invalid area information.

The sensor 52 detects the contact caused by the grip of the user, and outputs a voltage indicating ON when the sensor 52 is in contact and a voltage indicating OFF when the sensor 52 is not in contact.

FIG. 2 is a schematic block diagram of the mobile terminal 5 according to the first embodiment of the present invention.
Further, 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, so that the application execution unit 501, the touch input detection unit 502, the grip detection unit 503, the user determination unit 504, and the invalid area identification unit are executed. It includes 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 the 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 has touched the touch panel 51, and a contact area which is a coordinate area on the touch panel 51 where the user and the touch panel 51 have come into contact with each other.
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 identification unit 505 identifies the contact area detected by the touch input detection unit 502 as an invalid area when the invalid area setting application is executed by the application execution unit 501.
The storage unit 506 stores the invalid area specified by the invalid area identification unit 505 and the identification information acquired by the user determination unit 504 in association with each other.
When the invalid area identification unit 505 identifies 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 identification unit 505. ..

When the contact area detected by the touch input detection unit 502 is not included in the invalid area stored by the storage unit 506, the input unit 508 sets 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 the display image from the application execution unit 501 and displays the display image on the touch panel 51.

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 the invalid area is set will be described. FIG. 3 is a flowchart showing the operation of the mobile terminal 5 according to the second embodiment when the 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 executing the invalid area setting application, the application execution unit 501 outputs a display command of a message prompting the user to grasp the terminal, such as "Please hold it in your hand", to the display control unit 509. As shown in FIG. 4A, the display control unit 509 displays the message acquired from the application execution unit 501 on the touch panel 51 (step S1). Note that FIG. 4 is a diagram showing a state of setting the invalid area.

When the display control unit 509 displays a message, the grip detection unit 503 determines whether or not the user has gripped the terminal (step S2). Specifically, the determination as to whether or not the sensor 52 is gripped is determined by 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 grip detection unit 503 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 has been gripped (step S2: YES), the invalid area identification unit 505 and the user determination unit 504 output a signal indicating that the terminal has been gripped. When the invalid area identification unit 505 receives a 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 to the recording unit 507 as an invalid area. To do. When the user discrimination unit 504 receives a 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 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 or not the ON / OFF matches for each sensor 52, and when the number of non-matching ones is equal to or less than a predetermined threshold value (for example, one), the storage unit 506 sets the storage unit 506. It is determined that the stored identification information is the same as or similar to the identification information received from the user discrimination unit 504.

When the recording unit 507 determines that none 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 S5: NO), the invalid area identification unit The invalid area specified by 505 is associated with the identification information received from the user determination unit 504 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 as or similar to the identification information received from the user determination unit 504 (step S5: YES), the storage unit 507 determines. 506 rewrites the invalid area stored in association with the identification information with 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 display command 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.

Determine (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 the 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 own 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 user identification information (step S12: YES). S13), the identification information is output to the input unit 508.

The input unit 508 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 S14). When the input unit 508 determines that some 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: YES), the storage unit 506 starts the storage unit 506. Read the invalid area associated with the identification information. 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 invalid area read out (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.

On the other hand, when it is determined in step S12 that the own 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 identification 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).

As described above, according to the present embodiment, even if the user comes into contact with the area previously recorded as the invalid area, the mobile terminal 5 does not consider the contact as an input. As a result, erroneous operation can be prevented by the hand holding the mobile terminal 5 coming into contact with the touch panel 51 regardless of the contact time 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 the grip of the own terminal. As a result, when the mobile terminal 5 is not gripped, the 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 by using the invalid area that matches the user. In the present embodiment, the case where the ON / OFF information of the sensor 52 is used as the identification information has been described, but the present invention is not limited to this, and 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 ON / OFF information as the identification information as in the present embodiment because the input processing of the identification information can be omitted.
