Augmented Light Bulb Turns a Desk Into a Touch Screen
[Philip Lelyveld comment: How many MIT Media Lab students does it take to change a light bulb?]
The LuminAR device, created by Linder and colleagues at the Media Lab, can project interactive images onto a surface, sensing when a person’s finger or hand points to an element within those images. Linder describes LuminAR as an augmented-reality system because the images and interfaces it projects can alter the function of a surface or object. While LuminAR might seem like a far-fetched concept, many large technology companies are experimenting with new kinds of computer interfaces in hopes of discovering new markets for their products (see “Google Game Could Be Augmented Reality’s First Killer App” and ”A New Chip to Bring 3-D Gesture Control to Smartphones”).
