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 touch panel;

an acceleration sensor detecting an acceleration value;

and a detecting unit detecting a specified operation based on an acceleration value detected by said acceleration sensor while an indication is being detected by said touch panel.

2. The portable device according to claim 1, wherein said detecting unit detects said 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 said detecting unit includes a moving average unit calculating a moving average of differential values output from said acceleration sensor for predetermined period of time to calculate a difference between a local maximum and a subsequent local minimum of calculated moving averages.

4. The portable device according to claim 1, further comprising a signal determining unit determining one out of a plurality of signals based on position information detected by said touch panel and a number of times said specified operation is detected by said detecting unit.

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

6. A method of detecting an operation performed by a portable device including a touch panel, comprising the steps of

detecting an acceleration value;

and

detecting a specified operation based on an acceleration value detected while an indication is being detected by said touch panel.

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

8. The method of detecting an operation according to claim 7, wherein said 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 a local maximum and a subsequent local minimum of calculated moving averages.

9. The method of detecting an operation according to claim 7, further comprising the step of determining one out of a plurality of signals based on position information detected by said touch panel and a number of times said specified operation is detected in said step of detecting.

10. The method of detecting an operation according to claim 7, wherein an acceleration value detected in said step of detecting is in a direction perpendicular to a panel surface of said touch panel.

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

detecting an acceleration value; and

detecting a specified operation based on an acceleration value detected while an indication is being detected by the touch panel.
