Patent number: 10537814Abstract: Camera base game controller, system and methods for video shooting games. The game controller is gun shaped which comprises a sight, camera, embedded computer, wireless communication, etc. A player aims at a target on TV screen with sight and captures pictures with camera. The sight's central axis points to a point on TV, known as “hit point” which is a point-of-aim on TV screen the player aiming to. The sight will project hit point to the picture center. Several methods, including algorithm with mathematical method, 1D and 2D screen coding methods are described to calculate the hit point coordinate on TV screen. The game controller will send this coordinate wirelessly to game computer, which connects to TV and will determine whether a target on TV is hit or not, and reacts accordingly. An alternative game controller design using smart phones directly for its camera and embedded computer is described also.Type: GrantFiled: December 12, 2016Date of Patent: January 21, 2020Inventors: Liwei Xu, Alan Xu
