According to a new patent filing, Sony is developing a wireless motion sensitive controller for the PlayStation 3 that will use a new type of “ultrasonic tracking system.”
The controller itself will break apart and combine to perform different actions.
“Game interface tracks the position of one or more game controllers in 3-dimensional space using hybrid video capture and ultrasonic tracking system,” reads the summary at the US Patent & Trademark office.
“The captured video information is used to identify a horizontal and vertical position for each controller within a capture area. The ultrasonic tracking system analyses sound communications to determine the distances between the game system and each controller and to determine the distances among the controllers,” reads the document.
