A Sensacell surface functions is an interactive touchscreen display, but on a large-scale framework.
Individual tile-like modules—each containing LED (Light-emitting diode) lighting and capacitive sensors—are connected in an open-ended array.
A constructed surface essentially functions as a multi-touch 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.
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 y-axis coordinates on a Cartesian grid.
