Apple has been working on its own, unique alternative to Kinect for Windows, a newly published patent application shows. Its design for a "three-dimensional imaging and display system" would have a device sit on the desk that would use one of multiple possible methods, such as tracking the reflection time or attenuation in light beams. It could let users get audible feedback on interacting with the environment, navigate a corresponding 3D desktop, and use head tracking for tasks like zooming in or scrolling.
