Abstract

An electronic device (1) prevents unintended operations when a contact position shifts, by having a display unit (20) that displays an object, a contact detection unit (10) that detects contact by a contacting body, a pressure detection unit (30) that detects pressure on the detection unit (10), and a control unit (60) that performs processing associated with the object displayed on the display unit (20) in accordance with a contact position of the contacting body in a region of the detection unit (10) corresponding to an receiving region of the object and with data based on pressure on the detection unit (10) acquired from the pressure detection unit (30), such that when the contact position of the contacting body changes as the data based on pressure increases, the control unit (60) changes the receiving region of the object in a direction of change of the contact position.

Claims

1. An electronic device comprising:

a display unit configured to display an object;

a contact detection unit configured to detect contact by a contacting body;

a pressure detection unit configured to detect pressure on the contact detection unit; and

a control unit configured to perform processing associated with the object displayed on the display unit in accordance with a contact position of the contacting body in a region of the contact detection unit corresponding to a receiving region of the object and in accordance with data based on pressure on the contact detection unit acquired from the pressure detection unit, wherein

when the contact position of the contacting body detected by the contact detection unit changes as the data based on pressure increases, the control unit changes the receiving region of the object in a direction of change of the contact position.

2. The electronic device according to claim 1, wherein the control unit changes the receiving region of the object in accordance with the direction of change of the contact position detected by the contact detection unit and with one of an amount of change of the contact position and the data based on pressure.

3. The electronic device according to claim 1, wherein the control unit dynamically changes the receiving region of the object.

4. The electronic device according to claim 1, wherein the control unit performs at least one of expanding and moving the receiving region of the object.
