A finger actuated display peripheral interface input device having a first axis roller for inputting positional information for a first axis and coupled to a transducer for producing a first signal indicative of the rotation of said first axis roller.

A first switch is adapted to produce a first switch signal upon actuation of said first switch. Both of the rollers can be rotated simultaneously or selectively. The miniature size rollers are located so close to each other that both axis rollers can be rotated simultaneously by a touch a finger pad of a distal phalanx of one finger to simultaneously change positional information in said first and second axes.
