Portable Terminal Apparatus, Portable Terminal Control Method, And Program
A portable terminal apparatus includes object display section which causes at least one operation target object to be displayed on a display unit, gripping force detecting section which detects a gripping force added to a casing, and display position control section which controls a display position of the operation target object on the display unit according to the gripping force detected by the gripping force detecting section. Accordingly, when a fingertip of a hand gripping the casing cannot reach an operation target object, the display position of the object is controlled to allow the fingertip to reach the object.
1 . A portable terminal apparatus comprising:
an object display section which causes at least one operation target object to be displayed on a display unit;
gripping force detecting section which detects a gripping force added to a casing; and
display position control section which controls a display position of the operation target object on the display unit according to the gripping force detected by the gripping force detecting section.
2 . The portable terminal apparatus according to claim 1 , wherein the display position control section moves the display position of the operation target object on the display unit to a position where an operation with one hand can be performed when the gripping force exceeds a predetermined threshold, and moves the display position of the operation target object for return to an original position when a state in which the gripping force exceeds the predetermined threshold is changed to a state in which the gripping force becomes below the predetermined threshold.
3 . The portable terminal apparatus according to claim 2 , wherein
the display position control section moves the display position of the operation target object to the position where the operation with one hand can be performed, at a constant speed or a variable speed.
4 . The portable terminal apparatus according to claim 3 , wherein
the display position control section changes a movement characteristic of the display position of the operation target object correspondingly to the gripping force detected by the gripping force detecting section.
5 . The portable terminal apparatus according to claim 2 , wherein
the display position control section changes a position of a move destination of the display position of the operation target object correspondingly to the gripping force detected by the gripping force detecting section.
6 . A portable terminal control method comprising:
an object display step of causing at least one operation target object to be displayed on a display unit;
a gripping force detecting step of detecting a gripping force added to a casing; and
a display position control step of controlling a display position of the operation target object on the display unit according to the gripping force detected in the gripping force detecting step.
7 . A non-transitory computer-readable storage medium having a program stored thereon that is executable by a computer in a portable terminal apparatus to perform functions comprising:
object display section which causes at least one operation target object to be displayed on a display unit;
gripping force detecting section which detects a gripping force added to a casing; and
display position control section which controls a display position of the operation target object on the display unit according to the gripping force detected by the gripping force detecting section.
