Abstract

In an electronic device, a pressure correcting unit corrects press pressure of a contact object on a touch panel unit based on a parameter of a contact area of the contact object on the touch panel unit, to thereby calculate a corrected pressure parameter. A process control unit determines whether confirmation operation is performed based on the corrected pressure parameter and a threshold.

Claims

1. An electronic device comprising:

a touch panel;

a memory; and

a processor that is connected to the memory, calculates a corrected pressure parameter by correcting a parameter of pressure applied by a contact object to the touch panel based on a parameter of a contact area of the contact object on the touch panel, and determines whether certain operation is performed based on the corrected pressure parameter and a threshold.

2. The electronic device according to claim 1, wherein

the parameter of the contact area is a long diameter of a contact region of the contact object on the touch panel, and

the processor calculates the corrected pressure parameter by reducing the parameter of the pressure as the long diameter increases.

3. An electronic device comprising:

a touch panel;

a memory; and

a processor that is connected to the memory, calculates a corrected threshold by correcting a reference threshold based on a parameter of a contact area of a contact object on the touch panel, and determines whether certain operation is performed based on a parameter of pressure applied by the contact object to the touch panel and the corrected threshold.

4. The electronic device according to claim 3, wherein

the parameter of the contact area is a long diameter of a contact region of the contact object on the touch panel, and

the processor calculates the corrected threshold by reducing the reference threshold as the long diameter increases.

5. A computer-readable, non-transitory, recording medium having stored therein a control program for causing an electronic device including a touch panel to execute a process, the process comprising:

calculating a corrected pressure parameter by correcting a parameter of pressure applied by a contact object to the touch panel based on a parameter of a contact area of the contact object on the touch panel; and

determining whether certain operation is performed based on the corrected pressure parameter and a threshold.
