  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

(Embodiment 1)
FIG. 1 is a block diagram showing a schematic configuration of the information processing terminal according to Embodiment 1 of the present invention.

  As shown in FIG. 1, the information processing terminal according to Embodiment 1 of the present invention includes an attitude sensor unit 2, an input control unit 3, a touch sensor unit 4, a timer unit 5, an application unit 6, a display control unit 7, and a display unit. 8 is provided.

  The posture sensor unit 2 is an input device such as an acceleration sensor, for example, and transmits the terminal posture information to the input control unit 3.

  When receiving the input information from the touch sensor unit 4, the input control unit 3 determines a case where the terminal is at a predetermined angle or more from the horizontal based on the input information of the posture sensor unit 2. When the angle is equal to or larger than a predetermined angle from the horizontal, input information from the touch sensor unit 4 (for example, coordinates of a place where the touch sensor is touched) is transmitted to the application unit 6 and waits for the next input. If the angle is not greater than a predetermined angle from the horizontal, it is determined whether the input information from the touch sensor unit 4 points to a designated area, for example, the lower left portion of the screen. In this case, it is determined whether or not the input information from the touch sensor unit 4 continues to indicate a predetermined screen area even after a predetermined time has elapsed. At that time, time lapse information is acquired from the timer unit 5, and a lapse of a predetermined time or more is determined. In this case, even if the input information from the touch sensor unit 4 is transmitted to the input control unit 3, the input control unit 3 does not transmit the input information to the application unit 6 (touch operation prohibited state, the same applies hereinafter). Further, when the input information from the touch sensor unit 4 deviates from a predetermined screen area, the input control unit 3 can transmit the information input from the touch sensor unit 4 to the application unit 6 again. Note that the predetermined angle in the case where the angle is greater than or equal to the predetermined angle from the horizontal can be set by the user. In addition, the user can set a predetermined time when time elapse information is acquired from the timer unit 5 and the elapse of a predetermined time or more is determined.

  When the touch sensor unit 4 detects contact with a finger, a stylus pen, or the like, the touch sensor unit 4 notifies the input control unit 3 as input information indicating a position (coordinates or the like) on the screen.

  The timer unit 5 has a role of transmitting the passage of time to the input control unit 3 as input information. In the case of the present invention, for example, when it is determined that the lower part of the screen is pointed, the input control unit 3 instructs the timer unit 5 to start measurement, and when the predetermined time has elapsed, the timer unit 5 notifies the input control unit 3. .

  The application unit 6 receives input information (for example, coordinates of a place where the touch sensor is touched) transmitted from the touch sensor unit 4 transmitted by the input control unit 3, and executes an application program or the like on the information processing terminal. Depending on the application program, a user interface or the like is displayed on the display unit 8 through the display control unit 7.

  The display control unit 7 creates a screen based on the information received from the application unit 6 and causes the display unit 8 to display the screen.

  The display unit 8 is various display devices such as an LCD (Liquid Crystal Display), and performs various displays when the display control unit 7 is used.

  FIG. 2 is a flowchart for explaining the operation of placing a predetermined screen area in a touch operation prohibited state in the information processing terminal according to Embodiment 1 of the present invention.

  First, the information processing terminal 1 stands by until there is an input from the touch sensor unit 4 (step S201).

  When the input information from the touch sensor unit 4 is detected (step S202), the input control unit 3 determines whether the information processing terminal 1 is at a predetermined angle or more from the horizontal based on the information of the posture sensor unit 2. (Step S203).

  When the angle is not greater than the predetermined angle from the horizontal (that is, when the angle is less than the predetermined angle from the horizontal) (No at Step S203), the input information of the touch sensor unit 4 is notified to the application unit 6 (Step S206). If the angle is greater than or equal to a predetermined angle from the horizontal (step S203, Yes), based on the input information from the touch sensor unit 4, the input control unit 3 determines whether or not a predetermined predetermined screen area is touched. Judgment is made (step S204).

  When the predetermined screen area set in advance is not touched (step S204, No), the input information of the touch sensor unit 4 is notified to the application unit 6 (step S206). When the predetermined screen area set in advance is touched (step S204, Yes), is the input control section 3 touching the predetermined screen area for a predetermined time or more based on the input information of the timer unit 5? It is determined whether or not (step S205).

  When the touch has not been made for a predetermined time (step S205, No), the input information of the touch sensor unit 4 is notified to the application unit 6 (step S206). When the predetermined screen area is touched (step S205, Yes), the input information from the touch sensor unit 4 is not notified to the application unit 6 (step S207). As a result, the application unit 6 cannot accept an operation from the user, and when the user holds the information processing terminal, an operation unintended by the user when the touch sensor is accidentally touched is performed. Can be prevented (touch operation prohibited state).

  In the case of the touch operation prohibited state, when the predetermined screen area is continuously touched (step S208), the state where the input information from the touch sensor unit 4 is not notified to the application unit 6 is continued (in the touch operation prohibited state). (Continuation) (step S207). If the predetermined screen area is not touched, the input information from the touch sensor unit 4 is again waited, and the application unit 6 can be notified (cancellation of the touch operation prohibition state) (step S201).

  FIG. 3 is not intended by the user when the user touches the touch sensor unit 4 accidentally by holding the information processing terminal with one hand (left hand) in the information processing terminal according to Embodiment 1 of the present invention. It is a figure which shows the operation | movement image when preventing operation. If the user keeps a predetermined screen area 302 set in advance when the inclination of the information processing terminal is greater than or equal to a predetermined angle from the horizontal and continues for a predetermined time or longer, the information processing terminal touches that area. However, the touch operation prohibition state is set so as not to react. Since the area 301 other than the predetermined predetermined screen area 302 is not in a touch operation prohibition state, the user can perform a touch operation, and even if the touch sensor unit 4 is touched, the information processing terminal does not malfunction and is stable. The area 301 other than the predetermined predetermined screen area 302 can be touched. 3 shows the case of the left hand, the same applies to the case of the right hand.

  As described above, according to the information processing terminal of the first embodiment, the operability of the information processing terminal is reduced by reducing the erroneous operation of the user touching the touch sensor accidentally by holding the information processing terminal. Can be improved. In particular, it is possible to reduce erroneous operations such as the case of holding with one hand.

(Embodiment 2)
A second embodiment of the present invention will be described. The configuration (block diagram) is the same as FIG. 1 in the first embodiment.

  FIG. 4 is a flowchart for explaining the operation for prohibiting the touch operation on the entire screen area in the information processing terminal according to Embodiment 2 of the present invention.

  First, the information processing terminal 1 stands by until there is an input from the touch sensor unit 4 (step S401).

  When input information from the touch sensor unit 4 is detected (step S402), the input control unit 3 determines whether or not the information processing terminal 1 is at a predetermined angle or more from the horizontal based on the information of the posture sensor unit 2. (Step S403).

  When the angle is not greater than a predetermined angle from the horizontal (No at Step S403), the input information of the touch sensor unit 4 is notified to the application unit 6 (Step S406). If the angle is greater than or equal to a predetermined angle from the horizontal (step S403, Yes), based on input information from the touch sensor unit 4, the input control unit 3 determines whether or not a predetermined screen area set in advance is touched. Judgment is made (step S404).

  When the predetermined screen area set in advance is not touched (No at Step S404), the input information of the touch sensor unit 4 is notified to the application unit 6 (Step S406). When a predetermined screen area set in advance is touched (step S404, Yes), is the input control section 3 touching the predetermined screen area for a predetermined time or more based on the input information of the timer unit 5? It is determined whether or not (step S405).

  If the touch has not been made for a predetermined time (step S405, No), the input information of the touch sensor unit 4 is notified to the application unit 6 (step S406). When the predetermined screen area is touched (step S405, Yes), the input information from the touch sensor unit 4 is not notified to the application unit 6 (step S407). As a result, the application unit 6 cannot accept an operation from the user, and when the user holds the information processing terminal, an operation unintended by the user when the touch sensor is accidentally touched is performed. Can be prevented (touch operation prohibited state).

  In the case where the touch operation is prohibited, if the predetermined screen area is continuously touched (step S408), the input information from the touch sensor unit 4 is not continuously notified to the application unit 6 (continuation of the touch operation prohibited state). (Step S407). If the predetermined screen area is not touched, the input information from the touch sensor unit 4 is again waited, and the application unit 6 can be notified (cancellation of the touch operation prohibition state) (step S401).

  FIG. 5 is a diagram showing an operation image when preventing an erroneous operation in which the user touches the touch sensor unit 4 accidentally by holding the information processing terminal with both hands in the information processing terminal according to Embodiment 2 of the present invention. is there. It is the figure which assumed the image at the time of holding with both hands based on the image of FIG. If the user continues to hold the predefined areas 502 and 503 for a predetermined time or more in a state where the attitude of the information processing terminal is greater than or equal to a predetermined angle from the horizontal, the information processing terminal may touch the predetermined screen area. Disable touch operation so that operation is not possible. In this case, since the user holds with both hands, the area 501 in which the user can perform a touch operation is also considered to be a case where the touch operation is not performed, and even if all the screen areas (501, 502, 503) are touched, The entire screen area can be in a touch operation prohibition state so that the operation cannot be performed. For example, a viewing-only mode can be set. In this case, by preventing the input control unit 3 from notifying all the input information from the touch sensor unit 4 to the application unit 6, when the user holds the information processing terminal with both hands, the touch sensor unit 4 Even if touched by mistake, the terminal does not malfunction, and the information processing terminal can be held stably.

  As described above, according to the information processing terminal of the second embodiment, it is possible to reduce an erroneous operation in which the user touches the touch sensor accidentally by holding the information processing terminal, and the operability of the information processing terminal. Can be improved. In particular, it is possible to reduce erroneous operations when both hands are held.

(Embodiment 3)
Embodiment 3 of the present invention will be described. The configuration (block diagram) is the same as FIG. 1 in the first embodiment.

  FIG. 6 is a flowchart for explaining the operation of disabling the touch operation at the upper part of the screen and displaying the user interface at the lower part of the screen in the information processing terminal according to Embodiment 3 of the present invention.

  First, the information processing terminal 1 stands by until there is an input from the touch sensor unit 4 (step S601).

  When input information from the touch sensor unit 4 is detected (step S602), the input control unit 3 determines whether or not the information processing terminal 1 is at a predetermined angle or more from the horizontal based on the information of the posture sensor unit 2. (Step S603).

  If the angle is not greater than a predetermined angle from the horizontal (step S603, No), the input information of the touch sensor unit 4 is notified to the application unit 6 (step S606). If the angle is greater than or equal to a predetermined angle from the horizontal (step S603, Yes), based on the input information from the touch sensor unit 4, the input control unit 3 determines whether or not a predetermined predetermined screen area is touched. Judgment is made (step S604).

  When the predetermined screen area set in advance is not touched (No at Step S604), the input information of the touch sensor unit 4 is notified to the application unit 6 (Step S606). If the predetermined screen area set in advance is touched (step S604, Yes), is the input control section 3 touching the predetermined screen area for a predetermined time or more based on the input information of the timer section 5? It is determined whether or not (step S605).

  When the touch has not been made for a predetermined time (step S605, No), the input information of the touch sensor unit 4 is notified to the application unit 6 (step S606). If the predetermined screen area is touched (step S605, Yes), if the input information from the touch sensor unit 4 is within the predetermined screen area, the application unit 6 is not notified (step S607). However, if the input information from the touch sensor unit 4 is outside the predetermined screen area, the application unit 6 is notified. As a result, the application unit 6 becomes unable to accept an operation from the user regarding the predetermined screen area, and the user touches the touch sensor accidentally when holding the information processing terminal. An operation unintended by the user can be prevented (touch operation prohibited state). In addition, input information outside the predetermined screen area can be notified to the application unit 6.

  If the predetermined screen area is continuously touched in the touch operation prohibited state (step S608), the input information from the touch sensor unit 4 is not continuously notified to the application unit 6 (continuation of the touch operation prohibited state). (Step S607). If the predetermined screen area is not touched, the input information from the touch sensor unit 4 is again waited, and the application unit 6 can be notified (cancellation of the touch operation prohibited state) (step S601).

  FIG. 7 shows a case where the touch sensor unit 4 is touched when a terminal other than those shown in FIGS. 3 and 5 is held, and an application example of screen display in that case.

  For example, in the case of holding the upper part of the terminal, the user does not react even if the user defines the area 701 at the upper part of the terminal in advance and touches the area 701 like the areas 302 and 502 and 503 in FIG. Touch operation can be disabled. Further, in this case, since a screen operation other than the area 701 can be touched, the application unit 6 prepares a user interface 702 such as a menu and can be displayed on the display unit 8 through the display control unit 7. . The user can operate this user interface using the other hand that is not touched. As described above, the user interface can be switched by using the opportunity of the touch operation prohibition state.

  Note that the touch sensor unit 4 may have a function of sending a touch press event when it detects that a finger or a stylus pen is touched, and a touch release event when it detects that it has left. .

  In that case, the expression that the user keeps touching for a predetermined time or more as shown in S205 in FIG. 2 starts measuring the time from when the input control unit 3 receives the touch press event from the touch sensor unit 4, and the predetermined time or more has passed. This represents an operation in which the input control unit 3 determines this through the timer unit 5.

  Similarly, when it is determined whether or not the touch is continued as in FIG. 2, S208, it can be determined by a touch release event.

  Thus, since it is possible to use a touch release event when determining that a predetermined time or more has elapsed, when the touch press event is sent as input information from the touch sensor unit 4 in FIG. 3 may notify the application unit 6 that a touch press event has been sent.

  As described above, according to the information processing terminal of the third embodiment, it is possible to reduce an erroneous operation in which the user touches the touch sensor accidentally by holding the information processing terminal, and the operability of the information processing terminal. Can be improved. In particular, it is possible to reduce an erroneous operation when holding the device.

  The information processing terminal according to the present invention can reduce an erroneous operation in which the user touches the touch sensor accidentally by holding the information processing terminal in his hand and can improve the operability of the information processing terminal. This is useful for mobile phones, smartphones, PCs, etc. that may touch the touch sensor screen accidentally.
