Interactive Floating Displays and 3D LCDs
IO2 Technology has released HelioDisplay, a device which projects a 2D image into mid-air. Not only this, but a user can manipulate the image by sticking his or her fingers into it, Minority Report style. The image projected can be viewed from both sides, and the image’s translucency can be adjusted. It’s like a video projector, without the screen. Manipulating stuff “on screen” will be weird without tactile feedback, but think of the coolness factor!
Sharp in Japan is also releasing a laptop with a 3D LCD display. I read something about this a little while ago while it was still a prototype, but here it is on the market (albeit only in Japan). It doesn’t require special glasses (which filter out light so a different image goes to each eye), but employs another method to somehow trick each of our eyes into seeing separate images, which, slightly offset, give the impression of depth.
