The concept of turning any surface into a computational interface continues to bubble up. Natan Linder a student at MIT’s Media Lab, thinks that fitting one inside a light bulb socket, together with a camera and projector, could provide a revolutionary new kind of interface—by turning any table or desk into a simple touch screen. The LuminAR device under development at MIT's 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. Click on the image or the title to learn more.
