Abstract: A position sensing system enabling dynamic adjustment of the sensing by dynamically adjusting amplifier gain or comparator thresholds in response to received signals. The system compares the time a signal takes to travel from a transmitter in a mobile component to a plurality of receivers in a fixed component and, adjusts the amplifier gain or comparator thresholds if the difference in times measured by the receivers is large or at least one receiver does not detect a signal.

Abstract: According to various embodiments, the invention provides a method for establishing communication between a computer program in a computing system and a controller held in a hand of a user, comprising: capturing image data in a capture area in front of a display, the capturing configured to identify a two-dimensional location of the controller in the capture area; and capturing one-way sound communication between a location proximate to the display and a location at the controller, the sound communication being used to compute a third-dimensional location of the controller in the capture area.

Abstract: According to some embodiments of the invention, a controller attachment apparatus is provided, comprising: a handle portion configured to accept and hold a controller; and an attachment portion affixed to the handle portion such that it allows a covering to be diposed over the handle portion once the controller is placed into the handle portion. For such an embodiment, the attachment portion may be in the shape of a sporting good or a weapon. For example, with respect to sporting goods, the attachment portion may take the shape of a tennis racket, paddle tennis racket, golf club, baseball bat, hockey stick, lacrosse stick, or fishing rod. Alternatively, with respect to weapons, the head portion may take the shape of a sword, dagger, blade, a light saber, a gun, or a phaser.

Abstract: Systems and methods for generating special effect are provided. In one embodiment, the method includes: receiving an input information from a game controller; generating an output data set based on the input information received by the game controller at a game console; transmitting the output data to a stage kit; and generating special effects at the stage kit based on the output data received from the game console.
