Patent attributes
Devices, systems, and methods of use are presented for a smart shell that can be fitted by an end user to a video game controller that routes signals from various buttons or other sensors on the smart shell to a video game console. Signals can flow from the video game console back to the shell to operate tactile feedback motors, lights, or speakers. The smart shell can be clipped to the game controller by the end user and released after a game is played. The smart shell can be in the shape of a gun with sensors to determine which grips are being held and a sensor to determine if a player is holding the gun's scope to his face. Logic using the three sensors can robustly determine whether the user is holding the gun as a pistol, machine gun, or a sniper rifle, and can reflect the player's choice of style in the video game.
