Abstract

A mobile telephone includes a touch panel, an acceleration sensor which detects an acceleration, and an operation detection unit which detects a predetermined operation in accordance with the acceleration detected by the acceleration sensor while an instruction made by the touch panel is being detected. For this, it is possible to detect an operation to press the touch panel while a user finger is in contact with the touch panel.

Claims

1. A portable device comprising:

a display configured to display a plurality of keys, a plurality of characters being allocated to each of the plurality of keys;

a touch panel configured to detect whether each of the plurality of keys is touched;

an acceleration sensor that detects an acceleration value; and

a detecting module that detects a specified operation based on the acceleration value detected by the acceleration sensor, wherein

when the specified operation is detected one or more times by the detecting module while the touch panel detects that one of the plurality of keys is continued to be touched, the display displays a character selected from the plurality of characters based on the key continued to be touched and the number of times of the specified operation.

2. The portable device according to claim 1, wherein the detecting module detects the specified operation when a difference between a local maximum and a local minimum of differential values of acceleration values is equal to or larger than a predetermined threshold value.

3. The portable device according to claim 2, wherein the detecting module includes a moving average module that calculates a moving average of differential values output from the acceleration sensor for predetermined period of time to calculate a difference between the local maximum and a subsequent local minimum of calculated moving averages.

4. The portable device according to claim 1, wherein the acceleration sensor detects the acceleration value in a direction perpendicular to a panel surface of the touch panel.

5. A method of detecting an operation performed by a portable device including a display and a touch panel, comprising the steps of:

displaying a plurality of keys, a plurality of characters being allocated to each of the plurality of keys;

detecting whether one of the plurality of keys is touched, the step being performed by the touch panel;

detecting an acceleration value;

detecting a specified operation based on the acceleration value detected; and

when the specified operation is detected one or more times by the detecting step while it is detected that the one of the plurality of keys is continued to be touched, displaying a character selected from the plurality of characters based on the key continued to be touched and the number of times of the specified operation, the displaying step being performed by the display.

6. The method of detecting the operation according to claim 5, wherein the step of detecting includes the step of detecting the specified operation when a difference between a local maximum and a local minimum of differential values of acceleration values is equal to or larger than a predetermined threshold value.

7. The method of detecting the operation according to claim 6, wherein the step of detecting includes the steps of:

calculating a moving average of differential values of acceleration values for a predetermined period of time; and

calculating a difference between the local maximum and a subsequent local minimum of calculated moving averages.

8. The method of detecting the operation according to claim 6, wherein the acceleration value detected in the step of detecting is in a direction perpendicular to a panel surface of the touch panel.

9. A non-transitory computer-readable storage medium storing a program for detecting an operation executed by a portable device including a display and a touch panel, for causing a computer to execute the steps of:

displaying a plurality of keys, a plurality of characters being allocated to each of the plurality of keys;

detecting whether one of the plurality of keys is touched, the step being performed by the touch panel;

detecting an acceleration value;

detecting a specified operation based on the acceleration value detected; and

when the specified operation is detected one or more times by the detecting step while it is detected that the one of the plurality of keys is continued to be touched, displaying a character selected from the plurality of characters based on the key continued to be touched and the number of times of the specified operation, the displaying step being performed by the display.
