Sony recently filed a patent that describes a method for determining the location of a PS Move-like controller through a sound capturing device. The patent describes the two-dimensional light-tracking that the current Move device uses in conjunction with sounds emitted from the controller, which would provide a gauge for the controller's "depth" in association with the sound capture device located on the TV.
What's more, the patent includes a number of pictures that show a Move-like controller with swappable face plates for different button setups, as seen after the break, as well as the ability to attach controllers together in a number of ways. Among the patent's illustrations is one depicting a child performing a bicycle kick while playing a soccer game with Move controllers attached to his hands and legs. Simulation sports games may never be the same.
