Video game control unit and attitude sensor

A video game comprising a video display terminal, computer means electrically connected to the video display terminal, player-actuated signal generating means for sending signals to the computer means comprising

• a generally horizontal rigid platform capable of supporting the weight of the user and adapted to receive the user's feet,
• a fulcrum mounted on the platform and adapted to contact a horizontal supporting surface, the fulcrum having a curved exterior surface,
• biasing means for resisting movement of the platform to highly tilted positions,
• gravity-actuated switch means for opening and closing a plurality of attitude-related electrical switches responsive to the direction of tilt of the platform, said switch means comprising a housing having an internal peripheral wall, a plurality of discrete first electrical contacts uniformly spaced around the internal peripheral wall, a solid conductive gravity-actuated switch closure member centrally mounted in the housing and freely movable in all lateral directions such that tilting of the housing causes the switch closure member to more by gravity into contact with at least one of the first electrical contracts, and a second electrical contact member adapted to maintain permanent electrical contact with the switch closure member, and
• transmission means for conveying signals from the electrical switches to the computer means.
