Apple has applied for a patent on an interactive device that could project a holographic 3D image into a small space and respond to movements of human hands within that space. The device described in the application includes three parts: a 3D display system, an optical based system that translates 2D images to 3D, and sensors to read hand movements. All of the components would of course connect to a central control mechanism that together would create the illusion of a three dimensional object hovering over a base, that responds to human manipulation.

The image that is projected is created digitally using lasers sent into a medium such as a crystal so that it could be seen by the human eye. Lasers would also be used to follow hand movements, allowing for precise gesture control. The result would be what the Apple team describes as "hologram-like illusions."

The application was submitted by Apple in October of 2012. Whether Apple has been pursuing the project is unknown, though it appears likely as Microsoft, Amazon and other competitors have made clear their intentions to build a similar device.
