Abstract: A method and apparatus for determining a vertical and horizontal (X-Y) target shot position on a Liquid Crystal or Plasma display screen may be adapted to connect to commercially available video game console systems. Upon a trigger event from a light gun when it is pointed at the target shot position, a blanking signal renders the monitor black during a first vertical refresh cycle. During a second vertical refresh cycle, the voltage to each of the red, blue and green channels is increased in three separate screen sections to create a display split between the three colours. The light gun is adapted to be capable of separately detecting a blue, red or green light pulse and the X-Y coordinates of the target shot position is determined on the basis of the colour detected by the light gun and the length of time which elapses between the start of the second vertical refresh cycle and the detection of the red, blue or green light pulse.

Abstract: A video game tactile feedback system includes an electronic circuit for receiving tactile feedback signals from a video game, and generating electronic pulses to a conductive pad forming part of or attached to a video game controller. A video game player may grasp the controller in contact with the conductive pad and experience tactile feedback through the conductive pad.

Abstract: A video game controller device includes a left hand controller having standard left hand video game controls, and a right hand controller having motion detection means to translate game user input into video game movement. Both the left hand and right hand controllers are operatively connected to a video game console.

Abstract: A video game controller includes separate left hand and right hand controller shells. The left hand controller has a conventional joystick movement controller, while the right hand controller has a trackball movement controller. One or both of the left hand and right hand controllers include a sensitivity module which augments or diminishes the movement signal sent by the controller in response to player input.

Abstract: A method and apparatus for producing a stereoscopic 3D image in a video game being displayed on a television or video monitor. The game player look-at position is shifted laterally to the left and right of the actual player look-at position during alternating vertical refresh cycles. A pair of liquid crystal glasses may be synchronized to the vertical refresh cycle such that a player wearing the glasses alternately sees the left-shifted image and the right-shifted image, producing a stereoscopic 3D image.

Abstract: A method and apparatus for projecting two-dimensional laser light images includes rotating horizontal scan and vertical scan mirrors. Each rotating mirror includes a plurality of planar reflecting surfaces arranged such that a cross-section through the mirrors has a regular polygonal shape.

Abstract: 5A method and apparatus for displaying flicker free stereoscopic images on a television monitor whereby Shutter Glasses alternate at three times faster than the refresh rate of display device, including the formatting required to view stereoscopic perspective images on the display device.
