摘要：
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.
