Microsoft Surface-How it works
How does Microsoft Surface work? Surface uses cameras to sense objects, hand gestures and touch. This user input is then processed and displayed on the surface using rear projection. Specifically: Surface uses a rear projection system which displays an image onto the underside of a thin diffuser which is the table's surface. Infrared light is also projected onto the underside of the diffuser. Objects such as fingers are visible through the diffuser by series of infrared–sensitive cameras, positioned underneath the surface of the tabletop. An image processing system processes the camera images to detect fingers, custom tags and other objects such as paint brushes when touching the display. The objects recognized with this system are reported to applications running in the computer so that they can react to object shapes, 2D bar codes (tags), movement and touch.
