Abstract: In a system and method for simulating a ball movement game, the system includes an input ball adapted to enable movement of a simulated ball in a graphical representation of the simulated game, responsive to movement of the input ball imparted by the player. The system further includes an air bearing for supporting the input ball so as to enable the player to directly impart movement to the input ball. The system also includes an optical encoder for generating the parameters of movement of the simulated ball responsive to detecting the parameters of movement of the input ball imparted by the player. The system still further includes a processor and software adapted to simulate a ball and movement of the simulated ball, responsive to the parameters of movement of the input ball detected by the optical encoder, and to simulate a game environment for movement of the simulated ball therein.

Abstract: Multiple large screens on movable arms form a gateway beneath which viewers may walk. The screens slide up or down, i.e., toward or away from, the viewers walking below. The screens also pivot in a circular arc to sweep toward, or away from, the viewers. In one embodiment a number of vertical support beams are employed. Elongated arms are attached to the support beams at one end so that the arms can each be rotated about their attached ends. The arms also slide up and down the length of the support beams. Projection screens are attached to the arms so that the screens move as the arms move. In a more specific embodiment each screen is provided with a rear-projection projector for displaying images onto the screens. A computer is used to control the sliding and rotating of the support beams so that preprogrammed patterns can be executed. A computer is also used to control the projectors so that coordinated patterns of images are displayed on the screens.
