Description

  The present invention relates to a portable terminal capable of shifting to an operation invalidation mode that invalidates an operation input, a portable terminal control method, and a program.

  One of functions required for a portable terminal such as a cellular phone is an information protection function that prevents information stored in the terminal from being seen by a third party. Another function required for the portable terminal is an erroneous operation prevention function that prevents an operation input different from the user's intention. Hereinafter, the information protection function and the erroneous operation prevention function are collectively referred to as a terminal protection function.

  As one of the methods for realizing the terminal protection function, there is a method in which the portable terminal shifts to an operation invalid mode in which an operation input to the portable terminal is invalidated. By disabling the operation input, it becomes impossible for a third party to steal information by operating the mobile terminal, and an operation input not intended by the user is not performed.

  As an opportunity for the mobile terminal to shift to the operation invalidation mode, various things have been studied according to the usage mode of the user, such as a change in the open / close state of the mobile terminal configured to be openable and closable. In particular, while the user is walking, the mobile device may not be noticed even if the mobile device is dropped, or buttons may be pressed while the mobile device is put in a bag, etc. It is desirable to have migrated.

  Therefore, in Patent Document 1 (Japanese Patent Application Laid-Open No. 2003-298690), it is detected whether or not the user is walking, and the operation invalidation mode is entered upon detection that the user is walking. A portable terminal that cancels the operation invalidation mode by a predetermined operation input is disclosed.

  According to the portable terminal disclosed in Patent Document 1, since the portable terminal shifts to the operation invalid mode while the user is walking, a third party who has picked up the portable terminal dropped by the user while walking is stealing information. In addition, even if a button or the like is pressed, it is not treated as an effective operation.

  However, in the portable terminal disclosed in Patent Document 1, since the portable terminal always shifts to the operation invalid mode during walking, it is inconvenient that the user cannot perform the operation input even when the user wants to input the operation while walking. There's a problem.

  Therefore, Patent Document 2 (Japanese Patent Application Laid-Open No. 2006-053740) discloses a technique in which the mobile terminal shifts to the operation invalid mode when a non-operation state in which no operation input is performed continues for a predetermined time or longer. . If this technology is applied to the portable terminal disclosed in Patent Document 1, the user can perform an operation input even while walking unless the no-operation state continues for a predetermined time or longer.

JP 2003-298690 A JP 2006-053740 A

  In the portable terminal disclosed in Patent Document 1 to which the technology disclosed in Patent Document 2 is applied, when the non-operation state continues for a predetermined time or longer, the operation shifts to the operation invalidation mode. For example, the user uses the playback application while walking. When listening to music and listening to music continuously for a predetermined time or longer, even if you try to perform operations such as fast-forwarding, the mobile terminal is in the operation invalid mode and you can perform operation input There are things that cannot be done. Therefore, when the user is walking while using the application, the mobile terminal described above has a problem that the operation cannot be shifted to the operation invalidation mode according to the application being used.

  EMBODIMENT OF THE INVENTION Below, the form for implementing this invention is demonstrated with reference to drawings.

(First embodiment)
FIG. 1 is a block diagram showing the configuration of the mobile terminal 10 according to the first embodiment of the present invention.

  The mobile terminal 10 is a mobile phone, a portable game machine, a notebook personal computer, etc. that is carried by the user.

  A mobile terminal 10 illustrated in FIG. 1 includes an operation unit 11, a walking determination unit 12, a control unit 13, a storage unit 14, and a display unit 15.

  The operation unit 11 outputs a control signal corresponding to the operation input from the user to the control unit 13. Specific examples of the operation unit 11 include a keyboard, a mouse, and a touch panel.

  The walking determination unit 12 includes an acceleration sensor 121 that detects acceleration. Based on the acceleration detected by the acceleration sensor 121, the walking determination unit 12 performs walking determination to determine whether the user is walking, and the determination result is transmitted to the control unit. 13 is output.

  The control unit 13 activates an application provided in the mobile terminal 10 in response to an operation input via the operation unit 11.

  Moreover, the control part 13 memorize | stores in the memory | storage part 14 whether it can be used during a user's walk about the application with which the portable terminal 10 is provided. Hereinafter, an application stored in the storage unit 14 that can be used while the user is walking is referred to as an available application.

  In addition, when a determination result indicating that the user is walking is output from the walking determination unit 12, the control unit 13 indicates that the active application can be used while the user is walking. 14 shifts to the operation invalid mode depending on whether or not it is stored in the memory 14. In addition, when a predetermined operation input is performed during the transition to the operation invalid mode, the control unit 13 cancels the operation invalid mode.

  The memory | storage part 14 memorize | stores whether it can use during a user's walk about the application with which the portable terminal 10 is provided.

  The display unit 15 displays various screens.

  Next, the operation of the mobile terminal 10 of this embodiment will be described.

  In the present embodiment, it is assumed that the user sets whether or not the application included in the mobile terminal 10 can be used during walking, and the operation at the time of setting is described with reference to FIGS. 2A and 2B. To do.

  First, the control unit 13 causes the display unit 15 to display a screen 21 for selecting whether or not to enable the terminal protection function that shifts to the operation invalid mode while the user is walking as illustrated in FIG.

  When the effect of enabling the terminal protection function is input, the control unit 13 causes the display unit 15 to display a screen 22 showing a list of applications included in the mobile terminal 10 illustrated in FIG. Allow the user to enter whether or not it can be used.

  When it is input for each application whether or not it can be used during walking, the control unit 13 stores the input content in the storage unit 14 in association with each application.

  Next, the operation of the mobile terminal 10 when the terminal protection function is valid will be described with reference to the flowchart shown in FIG.

  When the effect of enabling the terminal protection function is input, the control unit 13 instructs the walking determination unit 12 to perform the walking determination, and the walking determination unit 12 receives the instruction and periodically walks. Make a decision and output the decision result.

  When a determination result indicating that the user is walking is output from the walking determination unit 12 (step S31), the control unit 13 determines whether or not the mobile terminal 10 is unused (step S32). .

  Here, the control unit 13 determines that the mobile terminal 10 is in use when the active application is an available application, and even if the application is in operation when it is not an available application, It is determined that the mobile terminal 10 is unused.

  When the portable terminal 10 is in use (step S32: No), the control unit 13 ends the process. That is, when the running application is a usable application, the control unit 13 ends the process without shifting to the operation invalid mode.

  When the portable terminal 10 is unused (step S32: Yes), the control unit 13 indicates that the determination result of the walking determination that is periodically output indicates that the user is walking. Depending on whether or not, it is determined whether or not the user's walking is continued (step S33).

  When a user's walk is not continuing (step S33: No), the control part 13 complete | finishes a process.

  When the user's walking continues (step S33: Yes), the control unit 13 determines whether or not the user's walking state exceeds a predetermined threshold value α (step S34).

  Note that the walking state of the user includes the number of steps, walking time, walking distance, and the like.

  When setting the number of steps to the walking state, the control unit 13 compares the number of steps obtained based on the acceleration detection result with a threshold value α (for example, 100 steps). When the walking time is set to the walking state, the control unit 13 compares an elapsed time after the user starts walking with a threshold value α (for example, 5 minutes). When the walking distance is set to the walking state, the control unit 13 calculates the walking distance obtained by multiplying the previously stored stride (for example, 70 cm) by the number of steps obtained based on the acceleration detection result and the threshold α ( For example, 70m) is compared.

  When the walking state does not exceed the threshold value α (step S34: No), the control unit 13 returns to the process of step S32.

  When the walking state exceeds the threshold value α (step S34: Yes), the control unit 13 shifts to the operation invalidation mode and invalidates the operation input via the operation unit 11.

  As described above, according to the present embodiment, the portable terminal 10 shifts to the operation invalid mode if the usable application is not operated while the user is walking, and operates if the usable application is activated. The operation input remains valid without shifting to the invalid mode.

  Therefore, it is possible to shift to the operation invalid mode according to the usage status of the application while the user is walking.

(Second Embodiment)
FIG. 4 is a block diagram showing the configuration of the mobile terminal according to the second embodiment of the present invention. In FIG. 4, the same components as those in FIG.

  Compared with the mobile terminal 10 of the first embodiment, the mobile terminal 40 of the present embodiment is different in that the proximity determination unit 41 is added and the control unit 13 is changed to the control unit 42.

  The proximity determination unit 41 performs proximity determination for determining whether or not an object is in proximity to the mobile terminal 40, and outputs the determination result to the control unit 42.

  In addition to the operation of the control unit 13, the control unit 42 causes the proximity determination unit 41 to perform proximity determination, and shifts to the operation invalid mode according to the determination result of the proximity determination.

  Next, the operation of the portable terminal 40 when the terminal protection function is valid will be described with reference to the flowchart shown in FIG. In FIG. 5, the same processes as those in FIG.

  When the determination result indicating that the user is walking is output from the walking determination unit 12 (step S31), the control unit 13 instructs the proximity determination unit 41 to perform the proximity determination, and the proximity determination unit 41 Receives the instruction, performs proximity determination, and outputs a determination result (step S51).

  The proximity determination unit 41 includes, for example, a camera, and performs proximity determination based on a captured image captured by the camera. The proximity determining unit 41 includes, for example, a light emitting unit that outputs infrared light or the like to the outside of the mobile terminal 40, and a light receiving unit that receives reflected light reflected by an external object. And the proximity determination is performed based on the light receiving state in which the light receiving unit receives the reflected light.

  When the determination result indicating that the object is approaching the portable terminal 40 is output from the proximity determination unit 41, the control unit 52 proceeds to step S35 and transitions to the operation invalid mode.

  On the other hand, when the determination result indicating that the object is not approaching the portable terminal 40 is output from the proximity determination unit 41 (step S51: No), the control unit 52 proceeds to the process of step S32.

  When the user puts the portable terminal 40 in a bag or pocket, the necessity of operating the portable terminal 40 immediately is often low. In this case, the terminal protection function can be realized by the mobile terminal 40 shifting to the operation invalid mode.

  As described above, according to the present embodiment, when the object is close, the portable terminal 40 shifts to the operation invalidation mode even when the usable application is in operation.

  When an object is close to the mobile terminal 40, it is often less necessary for the user to operate the mobile terminal 40 immediately. Therefore, the terminal protection function is realized by shifting to the operation invalid mode. Can do.
