1. A portable electronic apparatus comprising:
- a touch sensor configured to detect a touch position;
a supporting-point position detecting unit configured to detect a supporting-point position of a user'"'"'s finger when the finger moves in a state in which the portable electronic apparatus is held;
a user'"'"'s finger length acquiring unit configured to acquire the length of the finger; and
a touch region setting unit configured to set a touch region in which a touch operation serving as a predetermined input operation is received within a movable range of the finger obtained based on the supporting-point position of the finger and the length of the finger in a region in which the touch sensor is able to detect a touch.

Abstract
A supporting-point position detecting unit detects a supporting-point position of a thumb when the finger moves in a state in which a portable electronic apparatus (portable information apparatus) is held, and a finger length acquiring unit acquires a length of the thumb. Then, an application processing unit sets a touch region (for example, a display region of an icon of a push button) in which a touch operation serving as a predetermined input operation is received within a movable range of the finger obtained based on the supporting-point position of the thumb and the length of the thumb in a region in which the touch sensor is able to detect a touch.
