ABSTRACT:
An information input device has a device body made of an elastically deformable material. The device body can be held in a palm and operated with one hand. The device body is provided in its face with a touchpad. A pressure sensor and an acceleration sensor are independently provided in the device body. The device body includes therein an RF module for transmitting a sensor signal from each sensor to a personal computer. By a control unit (CPU) in the device body, for example, a determination signal for determining an operation on the touchpad as input data is assigned to the pressure sensor, and a canceling signal for canceling the determination signal is assigned to the acceleration sensor. Thus, the user need not operate the device body on a desk or the like. The user can easily hold and operate the device body with one hand, without restriction of place to operate.
