touchscreen, but with additional capabilities due to the nature of the capacitive sensors used in the tiles. The sensing electrodes can detect, without physical contact, persons and objects moving in proximity to the surface, to a distance of 150mm. The ability to detect proximity provides a third variable of user input. A traditional touchscreen collects information on the two-dimensional plane of the surface itself; a “touch” or other input is translated into x-axis and
