Abstract

[Object]

To provide a portable terminal device accepting an input operation in accordance with acceleration, which is less prone to cause incorrect input and allows a user to perform easily an input operation.

[Constitution]

A mobile phone includes an acceleration sensor 13 for detecting acceleration produced on a mobile phone main body; a cumulative value calculating section 100a for calculating a cumulative value of detected acceleration; a comparing section 100b for comparing the cumulative value with a threshold value; and a CPU 100 for controlling a security lock mode in accordance with a result of comparison by the comparing section 100b. When the cumulative value has exceeded the threshold value by a user shaking the mobile phone, the CPU 100 cancels the security lock mode.

Claims

1. A portable terminal device, comprising:

an acceleration detecting section that detects acceleration produced when a user shakes the portable terminal device as an input operation;

a comparing section that compares the acceleration detected by the acceleration detecting section with a threshold value;

a counter that counts the number of times the acceleration detected by the acceleration detecting section has exceeded the threshold value in accordance with a result of comparison by the comparing section;

a display section that displays a notification to inform the user that the user is performing the input operation; and

a control section that controls a corresponding function when the number of times counted by the counter has reached a prescribed number of times.

2. The portable terminal device according to claim 1, wherein

the input operation is an operation for authentication.

3. The portable terminal device according to claim 1, wherein

the control section cancels a lock function for disabling key operations as the control of the corresponding function.

4. The portable terminal device according to claim 1, wherein

the control section switches an display on the display section from an off state to an on state as the control of the corresponding function.

5. The portable terminal device according to claim 1, wherein

the control section changes an image on a standby screen displayed on the display section as the control of the corresponding function.

6. A non-transitory storage medium for storing a program, the program providing a computer of a portable terminal device including an acceleration detecting section, a display section, and a counter with functions of:

comparing acceleration detected by the acceleration detecting section with a threshold value, the acceleration being produced when a user shakes the portable terminal device as an input operation;

causing the counter to count the number of times the acceleration detected by the acceleration detecting section has exceeded the threshold value;

causing the display section to display a notification to inform the user that the user is performing the input operation; and

controlling a corresponding function when the number of times counted by the counter has reached a prescribed number of times.

7. A control method of a portable terminal device including an acceleration detecting section that detects acceleration produced when a user shakes the portable terminal device as an input operation, a display section, and a counter, the method comprising steps of:

comparing acceleration detected by the acceleration detecting section with a threshold value, the acceleration being produced when a user shakes the portable terminal device as an input operation;

causing the counter to count the number of times the acceleration detected by the acceleration detecting section has exceeded a threshold value, and the display section to display a notification to inform the user that the user is performing the input operation; and

controlling a corresponding function when the number of times counted by the counter has reached a prescribed number of times.
