PORTABLE INFORMATION TERMINAL AND METHOD FOR CONTROLLING SAME
First Claim
1. A portable information terminal equipped with a case that can be held by a user, comprising:
- a display area disposed on a front surface of the case, the display area being provided to display an image;
a rear input section disposed on a back surface of the case on a reverse side from the front surface, the rear input section being provided to receive an operation input resulting from two or more fingers of the user approaching, touching, or pressing the rear input section;
a hold detection section that detects holding of the case by the user; and
a command recognition section that recognizes an operation input resulting from the fingers approaching, touching, or pressing the rear input section, the command recognition section executing a pre-associated process command in response to the recognized operation input made by said finger,wherein, when the hold detection section does not detect holding of the case, the command recognition section switches to a command non-receiving state in which the process command is not executed, and when the hold detection section detects holding of the case, the command recognition section switches to a command receiving state in which the process command can be executed.

Abstract
The disclosed portable information terminal (10) is compact enough to be held in one hand, and when the device is being held in one hand by a user, the thumb of one hand placed on a display area (14) is detected by a transparent touch panel provided on the display area (14). At the time of detection, the terminal returns from standby mode, and therefore, a command will not be erroneously executed. Also, operation input is recognized resulting from a finger (aside from the thumb) approaching, touching, or pressing a touch panel (261) provided on the reverse side from the surface to which the display area (14) is provided, and a pre-associated process command is executed in response to the finger operation input that was recognized, and therefore, a suitable operation input interface for one hand is achieved.

8. A method of controlling a portable information terminal equipped with a case that can be held by a user, the method comprising:
-
a display step of displaying an image on a display area disposed on a front surface that is a prescribed surface of the case; a rear input step of receiving an operation input resulting from two or more fingers of the user approaching, touching, or pressing a rear input section disposed on a back surface that is a surface of the case on a reverse side from the front surface; a hold detection step of detecting holding of the case by the user; and a command recognition step of recognizing an operation input made in the rear input step by the fingers approaching, touching, or pressing the rear input section, and executing a pre-associated process command in response to a recognized operation input made by said finger, wherein, in the command recognition step, when holding of the case is not detected in the hold detection step, the process command is not executed, establishing a command non-receiving state, and when holding of the case is detected in the hold detection step, the process command can be executed, establishing a command receiving state.
