Description

Portable terminal, operation processing method, program, and recording medium

The present invention mainly relates to a portable terminal that receives an operation on a display screen, and an operation processing method using such a portable terminal.

Various portable terminals equipped with a touch panel (for example, tablet terminals, smartphones, etc.) are widely used. Such a portable terminal can accept an input operation with a finger on the display screen of the touch panel. Examples of such portable terminals include the portable terminals disclosed in Patent Documents 1 to 4.

In a mobile terminal equipped with a touch panel (particularly, a mobile terminal with a narrow frame area and a mobile terminal as shown in FIG. 13 without a frame area), the user touches the end of the touch panel unintentionally with the hand holding the terminal, Although the user may unintentionally perform an erroneous operation, the portable terminals disclosed in Patent Documents 1 to 4 can prevent such an erroneous operation to some extent.

For example, in the portable terminal of Patent Document 1, when a user sets an area on the touch panel that the user touches as an invalid area using an invalid area setting application, the invalidation by a user whose identification information is the same as or similar to that user The touch of the hand to the area is not treated as an input (see paragraphs 0016 to 0028 of FIG. 3, FIG. 3 and FIG. 5).

Thereby, the portable terminal of patent document 1 has a terminal, for example, when the user is operating the touch panel with the thumb of the hand holding the terminal while holding the terminal with one hand as shown in FIG. It is possible to prevent an erroneous operation due to the middle finger, ring finger, pinky finger, and / or thumb ball of the hand unintentionally touching the touch panel.

Japanese Patent Publication “JP 2012-234386 A” (published on November 29, 2012) Japanese Published Patent Publication “JP 2011-28603 A” (published on February 10, 2011) Japanese Patent Publication “JP 2013-69190 A” (published April 18, 2013) Japanese Patent Publication “JP 2000-39964 A” (published on February 8, 2000)

However, the portable terminal of Patent Document 1 cannot activate the above-described erroneous operation prevention function unless the user operates the invalid area setting application in advance. In addition, when a user with a terminal operates an invalid area setting application so that only a partial area of the touch panel is touched, the portable terminal of Patent Document 1 is another user whose identification information is similar to that user. May not prevent the above-described erroneous operation. This is because the size of the area on the touch panel where the hand holding the terminal can be touched unintentionally when holding the portable terminal depends on the characteristics of the hand (the size of the hand, the length of the finger, etc.). .

In addition, the portable terminal of Patent Document 2 is in a specific situation where it is easy to perform an erroneous operation (specifically, the user touches the thumb ball on the right side as shown in FIG. While holding the terminal with one hand so that the user's finger is in contact), the erroneous operation prevention function cannot be used because it is erroneously recognized as being operated with both hands.

Also, the portable terminal of Patent Document 3 cannot activate the erroneous operation prevention function when the user unintentionally touches the corner of the touch panel while performing a continuous touch operation. Furthermore, although the portable terminal of Patent Document 4 can operate the erroneous operation prevention function in the handwriting input mode, it cannot operate the erroneous operation prevention function in the normal display mode.

The present invention has been made in view of the above problems, and its main object is to realize a portable terminal capable of reliably operating an erroneous operation prevention function under a specific situation in which an erroneous operation is likely to occur. There is.

In order to solve the above-described problem, a mobile terminal according to an aspect of the present invention includes a display screen that receives an operation for designating coordinates, a contact detection unit provided on each of a plurality of side surfaces of the terminal, and a contact object. A determination unit that determines whether or not a plurality of the contact detection units are detecting, and when the determination unit determines that the plurality of contact detection units detect a contact object, And an invalidating unit for invalidating an operation for designating coordinates in a specific area.

In order to solve the above-described problem, an operation processing method according to an aspect of the present invention provides an operation process performed by a mobile terminal in which a display screen that receives an operation for specifying coordinates is provided and a contact detection unit is provided on a side surface of the terminal itself. In the method, the contact detection unit is provided on each of the plurality of side surfaces of the mobile terminal, and a determination step of determining whether or not the plurality of contact detection units detect a contact object; and An invalidation step of invalidating an operation of designating coordinates in a specific area in the display screen when it is determined in the determination step that the plurality of contact detection units detect a contact object. Contains.

The portable terminal according to one aspect of the present invention has an effect that the erroneous operation prevention function can be surely operated under a specific situation in which an erroneous operation is easily performed.

Next, the configuration of the main part of the smartphone 1 will be described with reference to FIG.

[Configuration of smartphone 1]
FIG. 1 is a block diagram showing a main configuration of the smartphone 1. As illustrated in FIG. 1, the smartphone 1 includes a storage unit 11, a control unit 12, two contact sensors (

contact sensors

13R and 13L), and a display unit 14.

(Storage unit 11)
The storage unit 11 stores an OS (Operating System) program, various application programs, various control programs, various data, and the like.

(Control unit 12)
The control unit 12 is a CPU that controls the smartphone 1 as a whole. The control unit 12 also functions as the application execution unit 121, the touch event control unit 122, and the sensor state detection processing unit 123 by reading the corresponding program from the storage unit 11.

(App execution unit 121)
The application execution unit 121 performs processing according to an application read from the control unit 12 (hereinafter, “application”). For example, the application execution unit 121 displays a user interface screen (UI screen) of the application on the display unit 14.

(Touch event control unit 122)
The touch event control unit 122 issues a touch event with the contact coordinates on the display screen as an argument to the foreground application.

In this regard, the touch event control unit 122 is configured to invalidate the touch operation that specifies the coordinates in the operation invalid area when both of the two contact sensors detect the touch of the hand. That is, the touch event control unit 122 does not issue a touch event even when a touch operation that specifies only coordinates in the operation invalid area is detected when both of the two contact sensors detect a hand contact. It has become.

In addition, the touch event control unit 122 includes an operation invalid area specifying unit 1221.

(Operation invalid area specifying unit 1221)
When both of the two contact sensors detect contact with the hand, the operation invalid area specifying unit 1221 reads data indicating the position and size of the operation invalid area and identifies the operation invalid area.

(Sensor state detection processing unit 123)
The sensor state detection processing unit 123 determines whether or not both of the two contact sensors are detecting the contact of the hand (contact object).

(Contact sensor 13R and contact sensor 13L)
The contact sensor 13R notifies the sensor state detection processing unit 123 that the contact of the hand is detected when the contact of the hand is detected. Similarly, the contact sensor 13L notifies the sensor state detection processing unit 123 that the hand contact is detected when the hand contact is detected.

(Display unit 140)
The display unit 140 is a touch panel display that displays a user interface screen of the application.

[Operation of smartphone 1]
Next, an operation performed by the smartphone 1 when the user touches one point on the touch panel (display screen) will be described with reference to FIGS. 3 and 4. FIG. 3 is a flowchart showing the operation, and FIG. 4 is a diagram illustrating an operation invalid area of the smartphone 1.

First, as shown in FIG. 3, the smartphone 1 checks the states of the two contact sensors (S1). Specifically, the touch event control unit 122 specifies the coordinates (touch coordinates) with which the hand on the touch panel is in contact, and determines whether or not both of the two contact sensors are touched with respect to the sensor state detection processing unit 123. Inquire.

In response to this, the sensor state detection processing unit 123 determines whether or not the notification that the contact of the hand is detected is received from both of the two contact sensors (S2).

When it is determined in S2 that both of the two contact sensors are touched (that is, the notification is received from both of the two contact sensors), the sensor state detection processing unit 123 displays the determination result as a touch event control unit. 122 is notified. When the smartphone 1 determines in S2 that one or both of the two contact sensors are not touched (that is, the notification is not received from one or both of the two contact sensors), the smartphone 1 proceeds to S6 described later. .

The operation invalid area specifying unit 1221 of the touch event control unit 122 that has received the notification reads data indicating the position and size of the operation invalid area from the storage unit 11. For example, the operation invalid area specifying unit 1221 includes the coordinates of the four corners of the rectangular operation invalid area (see FIG. 4) near the left end of the touch panel and the four corners of the rectangular operation invalid area (see FIG. 4) near the right end of the touch panel. Data indicating the coordinates is read (S3).

And the touch event control part 122 determines whether a touch coordinate is located in an operation invalid area | region based on the read data (S4).

The touch event control unit 122 displays information indicating that the touch operation is invalid on the display unit 140 when it is determined that the touch coordinates are located within the operation invalid region (S5). That is, the touch event control unit 122 ends the operation according to the flowchart of FIG. 3 without issuing a touch event having the touch coordinates as an argument to the application execution unit 121.

On the other hand, if the smartphone 1 determines that the touch coordinates are not located within the operation invalid area, the process proceeds to S6.

In S6, the smartphone 1 validates the touch operation and performs an operation according to the touch event. Specifically, the touch event control unit 122 issues a touch event with the touch coordinates as an argument to the application execution unit 121, and the application execution unit 121 executes processing corresponding to the touch event. The smart phone 1 complete | finishes the operation | movement according to the flowchart of FIG. 3 after S6.

(Advantages of smartphone 1)
As described above, the smartphone 1 includes the display screen (display unit 140) that accepts an operation for specifying coordinates, the contact sensors (contact sensor 13R and contact sensor 13L) provided on each of both side surfaces of the terminal, A sensor state detection processing unit 123 that determines whether or not both of the two contact sensors have detected the contact of the two, and a display screen when it is determined that both of the two contact sensors have detected the contact of the hand And a touch event control unit 122 that invalidates the operation on the operation invalid area.

According to the above configuration, for example, when the user places the smartphone 1 on the palm of one hand (that is, the user does not hold the smartphone 1 and one or both of the two contact detection units are hands). If no contact is detected, the malfunction prevention function will not work. That is, the smartphone 1 does not allow the erroneous operation prevention function to work under a situation where it is difficult to perform an erroneous operation. On the other hand, when the smartphone 1 is operated with the thumb of the hand holding the smartphone 1 and the hand (portion such as a thumb ball or little finger) holding the smartphone 1 during operation is unintentionally touching the operation invalid area, The touch operation that specifies the coordinates in the operation invalid area is invalidated. That is, the smartphone 1 activates an erroneous operation prevention function under a specific situation where an erroneous operation is easily performed. The erroneous operation prevention function works reliably regardless of the type of user who uses the smartphone 1 (for example, a user who does not know that the smartphone 1 has the erroneous operation prevention function).

Therefore, it can be said that the smartphone 1 does not operate the erroneous operation prevention function under a situation where it is difficult to perform an erroneous operation, and can reliably operate the erroneous operation prevention function under a specific situation where the erroneous operation is easily performed.

(Appendix 1 of Embodiment 1)
In the first embodiment, when the user touches one point on the touch panel with the hand, the smartphone 1 receives notification from both the two contact sensors that the hand contact is detected in S2. It was judged. However, the present invention is not limited to this.

In other words, the smartphone 1 periodically determines whether or not the user has received notification from both of the two contact sensors whether or not the user has touched the touch panel. The information indicating the determination result may be cached for each determination. And the smart phone 1 may perform the process after S3, without performing the process of S1 and S2, when a user makes a hand contact one point on a touch panel. In this case, the smartphone 1 may first determine whether to proceed to S3 or S6 based on the most recently cached information, and then execute the process of S3 or S6 based on the determination.

The smartphone 1B according to this modification is configured to dynamically change the size of the operation invalid area provided on the display screen while both of the two contact sensors detect contact with the hand.

Specifically, the smartphone 1B defines the first region in the display screen so that the position corresponds to the contact position detected by the contact sensor regardless of the presence or absence of a finger indicating the coordinates in the display screen. More specifically, the smartphone 1B defines the first area by using the same method as the method for defining the operation invalid area in FIG. Furthermore, when the finger points to the coordinates in the first area, the smartphone 1B defines a second area corresponding to the position of the coordinates in the display screen.

Then, the smartphone 1B defines the first area as an operation invalid area when the finger does not point to the coordinates in the first area, and when the finger points to the coordinates within the first area. An area including the first area and the second area is defined as an operation invalid area.

Since the configuration of the smartphone 1B according to the present modification is the configuration shown in FIG. 8 already described, the configuration of the smartphone 1B according to the present modification will not be touched again. Hereinafter, the operation of the smartphone 1 </ b> B according to this modification will be described with reference to FIGS. 11 and 12.

[Operation of Smartphone 1B according to Modification]
FIG. 11 is a flowchart showing the operation, and FIG. 12 is a diagram illustrating an operation invalid area of the smartphone 1B at the left end of the display screen. In FIG. 12, an area on the display screen and surrounded by a wavy line indicates an operation invalid area.

As shown in FIG. 11, first, the smartphone 1B performs the same process as S1 in S31, and performs the same process as S2 in S32.

When it is determined in S32 that both of the two contact sensors are touched, the contact position specifying unit 1232 determines the coordinates of the upper end and the lower end of the contact area between the contact sensor 13AR and the hand, and the contact sensor 13AL and the hand. The coordinates of the upper end and the lower end of the contact area are specified. Then, the operation invalid area determination unit 1221B determines the touch coordinates on the touch panel (target) that are located within a certain distance r (within the above-described first area) from any of the four specified coordinates. It is determined whether or not there is one or more (touch coordinates) (S33). In the example of FIG. 12, since the touch coordinates A and the touch coordinates B are located in the first area, it is determined that one or more target touch coordinates exist. If the smartphone 1B determines that one or both of the two contact sensors are not touched in S32, the process proceeds to S36.

When it is determined in S33 or S35 described later that one or more target touch coordinates exist, the touch event control unit 122B determines not to include all target touch coordinates in the argument of the touch operation event (S34). If the smartphone 1B determines that the target touch coordinates do not exist in S33, the process proceeds to S36.

After that, the operation invalid area determination unit 1221B is located on the touch panel such that the operation invalid area determination unit 1221B is located within a certain distance r from any one of the one or more coordinates determined not to be included in the argument of the touch operation event in S34. It is determined whether one or more touch coordinates (target touch coordinates) exist (S35). The smartphone 1B returns to S34 when it is determined that one or more target touch coordinates exist, and proceeds to S36 when it is determined that no target touch coordinates exist. In the example of FIG. 12, in the first time S35, the touch coordinate C is located within the fixed distance r (within the second region) from the touch coordinate A, and the touch coordinate D is within the fixed distance r (the second distance) from the touch coordinate B. 2), it is determined that one or more target touch coordinates exist. In S35 of the second time, since the touch coordinates E are located within a certain distance r from the touch coordinates D, it is determined that one or more target touch coordinates exist. On the other hand, in the third S35, since no remaining touch coordinates are located within the predetermined distance r from the touch coordinates E, it is determined that the target touch coordinates do not exist.

In S36, the touch event control unit 122B determines whether there is touch coordinates (target touch coordinates) that are not determined to be included in the argument of the touch event. In the example of FIG. 12, since the touch coordinates F correspond to the target touch coordinates, it is determined that the target touch coordinates exist.

When the touch event control unit 122B determines that the target touch coordinates exist in S36, the touch event control unit 122B issues a touch operation event having all the target touch coordinates as arguments to the application execution unit 121. And the application execution part 121 performs the process according to the issued touch operation event (S37). After S37, the smartphone 1B ends the operation according to the flowchart of FIG. On the other hand, when it is determined in S36 that the target touch coordinates exist, the touch event control unit 122 does not issue a touch event with the touch coordinates as an argument to the application execution unit 121, and performs the operation according to the flowchart of FIG. Exit.

(Additional notes of Embodiment 3)
A mobile terminal provided with a frame area may be used instead of the smartphone 1B. In this case, the operation invalid area determination unit of the mobile terminal determines that the area in the display screen adjacent to the “contact area with the finger in the contact sensor” is set as the operation invalid area, similarly to the operation invalid area determination unit 1221B. . Here, the contact area and the area in the display screen are “adjacent” means that the shortest distance between the contact area and the “area in the display screen” is the difference between the contact area and the entire area of the display screen. It is equal to the shortest distance between.

Although the mobile terminal according to the present invention can take various forms, the operation invalid area adjacent to the “contact area with the finger in the contact sensor” in each form by taking four types of mobile terminals as examples. The position of is shown in FIG.

FIG. 15 is a cross-sectional view of an outer edge portion of each mobile terminal (specifically, “parallel to the bottom surface” separated from the bottom surface by a distance d between the bottom surface of the mobile terminal and the center of the contact area of the contact sensor with the finger. It is the figure which showed typically the cross section cut off by the "face." As shown in FIG. 15, in any form of mobile terminal, an “area in the display screen” adjacent to the “contact area with the finger in the contact sensor” is set as an operation invalid area.

(Appendix 1 of Embodiments 1 to 3)
The smartphone according to each embodiment may be configured to display an image in the operation invalid area, but may be configured not to display an image in the operation invalid area.

Also, the portable terminal according to the present invention is not limited to a terminal whose front surface is covered with a touch panel and contact sensors are provided on two opposing side surfaces (left side surface and right side surface). That is, the mobile terminal according to the present invention may be a terminal provided with a touch panel that covers the left side, the front side, and the right side and is not provided with the two contact sensors described above. In this case, the portion of the touch panel that covers the left side surface and the portion of the display unit that covers the right side surface serve as a contact detection unit in the claims.

(Appendix 2 of Embodiments 1 to 3)
The portable terminal which concerns on this invention should just be provided with the contact sensor in the some side surface. For example, the mobile terminal according to the present invention may be a terminal A in which contact sensors are provided on two opposing side surfaces (upper side surface and lower side surface), or a contact sensor may be provided on each of four upper, lower, left, and right side surfaces. The terminal B provided may be used.

The touch event control unit of the terminal A performs a touch operation for designating coordinates in an operation invalid area including the upper end area and the lower end area of the display screen when both of the two contact sensors detect a hand contact. It may be made invalid. In this case, the terminal A is displayed unintentionally by the user's hand when the user is holding the upper and lower ends of the terminal A with both hands so that the left side or the right side of the terminal A faces upward. It is possible to prevent an erroneous operation caused by touching the screen.

Further, the touch event control unit of the terminal B displays the display screen when the contact sensor provided on the upper side and the contact sensor provided on the lower side of the four contact sensors detect the hand contact. The touch operation for designating the coordinates in the operation invalid area including the upper end area and the lower end area may be invalidated. Similarly, the touch event control unit of the terminal B displays when the contact sensor provided on the right side and the contact sensor provided on the left side of the four contact sensors detect a hand contact. The touch operation that specifies the coordinates in the operation invalid area including the right end area and the left end area of the screen may be invalidated.
