Abstract: A compact game controller incorporates an efficient and compact force feedback mechanism. Forces are generated at one of the controls of the controller in reaction to an action in a video game. The type of controller that can be held with two hands is limited in terms of size and internal space and in wireless versions is limited in terms of battery power. Efficient power consumption in the controller enables considerable usage time between battery replacement or recharging in wireless versions. The force feedback mechanism incorporates a double reduction gear system with a unique geometry which enables usage of a compact and energy efficient motor. The efficient force feedback mechanism and assembly can therefore be packaged within a compact ergonomic controller.

Abstract: A video game controller for home video game systems is situated between a player's feet and is used to detect positions outside the footprint of the controller. The controller transmits the position data to the video game system and enables game play. In dance games, the controller detects dance steps when the player dances around the controller. A signal is transmitted from locations at the perimeter of the controller, reflected by the player's foot, and then received back at the controller. In a preferred embodiment the location is detected as a function of the time the signal is transmitted/received and by the matrix of signals received. Modulation of the transmission and reception minimizes detection of noise and distant reflections and therefore minimizes or eliminates false position detection.
