Desk lamp enhances multitouch table top display
Dr. Li-Wei Chan and researchers from National Taiwan University (NTU) have developed a lamp that enhances interactivity on a multitouch table display. The lamp has infrared cameras to see hidden markers to compute its position in three dimensions. The calculated position would control how it projects additional high-resolution information onto correct places on the multitouch table top. More information is available in a NewScientist article.
