Abstract: The finger-operated input device connectable to a digital device is disclosed. The aforesaid input device comprises (a) a sensing pad being responsive to displacement of the finger substantially parallel to the pad in a reach range thereof and transmitting electrical signals in response thereto; and (b) an analyzing unit arranged to receive said electrical signals and calculate a data defining trajectory of the finger and transmit the data to the digital device; The sensing pad comprises at least three sensors perceptive to motion of the finger relative to the sensors.
