Ring-type Indirect Pointing Device for Large Displays using Three-axis Pressure Sensor

We present a ring-type pointing device that uses a three-axis pressure sensor for controlling a two-dimensional cursor shown on a large display. The pressure sensor attached to the ring measures the force applied to each axis to control the cursor. Specifically, the movement of the cursor is controlled on the basis of the forces applied on the x and y-axis, whereas tapping is controlled on the basis of the force applied on the z-axis. The cursor’s speed is controlled along with force on either axis: when applying a slight force, the cursor can be moved at a slower speed, which would be suitable for moving short distances; a stronger force can be applied for longer distances.
