Powerful computers are becoming small and cheap enough to cram into all sorts of everyday objects. 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, 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
Linder’s system uses a camera, a projector, and software to recognize objects and project imagery onto or around them, and also to function as a scanner. It connects to the Internet using Wi-Fi. Some capabilities of the prototype, such as object recognition, rely partly on software running on a remote cloud server.
