Abstract: Files such as musical pieces are represented in symbols such as a star, and are clustered based on the attribute of each file so as to be allocated in an information space. An impression, such as “refreshing”, on the musical piece corresponding to the file is represented and given in the form of emotion. The initial search for a file is carried out by roughly cutting out a marked-out space. When narrowed down, the file is linearly developed so as to support a user selection.

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.
