Kotaku discovered a patent listing a ton of possibilities. One idea adds “ultrasound communication” to the controller which helps the console locate the motion controller. Another draft gives the controller its own camera turning it into a magic wand camcorder. There’s even a potential baseball attachment and an illustration depicting two linked controllers.
There are expansions like maracas, a biometric reader, and (probably the most practical on the list) a two-handed controller for driving or “playing interactive games.” Perhaps, the sphere is removable and the key to converting the PS3 motion controller to a lite-up PS3 karaoke mic.
Sony also detailed what they consider to be a “fully loaded” controller.
Controller A includes a Clock Synchronization (CS) module used for clock synchronization with the base computing system; a Sound Receiver (SRx) for receiving ultrasonic data; a Sound Transmitter (SRx) for sending ultrasonic data; a WiFi (WF) module for WiFi communications with computing system 700; an Acoustic Chamber (AC) for conducting sound to and from the front and/or the sides of the controller; an Image Capture (IC) device, such as a digital video camera, for capturing image data; and a Light Emitter (LE) in the infrared or visible spectrum for easier image recognition from the image processing module at computing system 700.
So, how much is this thing going to cost?
