Definitions

  • the present invention relates generally to a system and method for controlling a cursor on a display screen, and more particularly to use of an acoustic based pointing device for controlling the cursor on the display screen.
  • a commercially available wireless pointing device exploits the gyroscopic effect. Consequently, such commercially available wireless pointing devices rely on the rotation of the pointing device which makes these pointing devices very unintuitive and inhibits the ability to track the positions of these pointing devices. Additionally, these pointing devices are fundamentally heavy since they need a large mass in order to exploit conservation of angular momentum.
  • the computing system is adapted to compute a position vector Pc for the cursor such that Pc depends on: P 0 , a scale vector A, and a shape function of the display screen; and means for positioning the cursor at a position Pc associated with the position vector Pc.
