The user interface revolution is not limited to surface computing. The emergence of portable video players and video-enabled mobile phones generates demand for a new generation of personal displays.
The challenge is to make it compact and provide high quality image. The Lumus series of eyeglass displays offer this with a nice natural look.
With the Lumus Binocular displays you can use virtual reality applications or play a 3D game anywhere on a large virtual screen in true color and VGA (640x480) resolution.
