A new type of computer input device is described. It consists of two oppositely facing touch -and position- sensitive panels (5) which are set in a suitable mounting. Most usually, the mounting (1) is held or supported in one hand of the user while the opposed thumb and a finger (usually the forefinger) of that hand touch one or both panels. Depending upon the position and, e.g., relative movements of positions of the contact points of thumb and forefinger with the respective panels, a wide variety of different manipulative commands may be distinguished by suitable circuitry and translated, e.g., into analogous manipulative commands to change the position of a representation of a three-dimensional object viewed on the computer screen. |
