156w ago - Just over a month ago Adafruit Industries offered and paid a bounty for an Open Kinect Driver, and today German site VideoGamesZone.de (linked above) reports that running homebrew Kinect applications may soon be possible on PS3 via OtherOS and API OpenNI drivers.
To quote, roughly translated: "Kinect for Xbox 360 might also operate on the PlayStation 3. Thanks to recent API OpenNI Drivers for Windows and Linux could allow PS3 consoles with older firmware with the OtherOS function also Kinect Underground.
The drivers allow access to all Kinect functions. Both the depth sensor and the audio and video capabilities of Kinect would theoretically available on the PlayStation 3.
So far, we have some Kinect videos from amateur hobbyists found, do the fun things with Kinect on the PC. Below are videos of a cool Minority Report-application and a player to come out with invisible Kinect makes.
A video to a Kinect application on the PlayStation 3 we have not found, yet."
160w ago - While Sony is currently promoting Move, today Siliconera.com (linked above) has uncovered a patent for a Kinect-like PlayStation device filed by Sony Computer Entertainment America.
While it's not a controller-free environment, the new controller device does track the location of players.
To quote: It's equipped with a gyroscope, accelerometer, magnometer, and most interestingly an ultrasonic transmitter. The controller uses this to communicate with another device to determine the location of the controller and player through echolocation.
The controller is half of the gizmo. Users also place this device on the floor and it communicates with a console via radio signals.
Sony equipped the floor sensor with a motion detector, cameras, sound processor, and another ultrasonic processor. Image detection lets it know where players are and if it has been moved.
Like the PlayStation Move controller, it has LEDs on top that provide visual feedback for in-game events and when your batteries are low. An onboard sound processor and microphone are present for voice control."
