A computer interface system that is worn on the middle fingers of both hands of the computer operator for controlling cursor movement is disclosed. The system includes a left and right hand fixed inner ring, the inner rings being of a dimension suitable to be worn on a portion of the middle fingers of the computer operator, and a left and a right rotatable outer ring. The system includes sensing elements disposed between each of the corresponding inner and outer rings for producing horizontal movement signals in response to the rotation of the left outer ring in relation to the left inner ring, and for producing vertical movement signals in response to the rotation of the right outer ring in relation to the right inner ring. The system also includes a pressure sensitive element disposed between corresponding inner and outer rings that produces an entry signal in response to the application of pressure on the outer ring toward the inner ring.
