Abstract
A system for a touch screen interface that includes a coating including a plurality of a touch activated microchips; and a projector for projecting a light image onto the coating that is applied to a touch screen substrate. The system also includes an image calibrator that calibrates touch activated microchips in the coating to features of the light image projected onto the coating. The system further includes a receiver for receiving signal from the touch activated microchips when said feature of the light image is activated.
Claims18
A method for forming a touch screen comprising:
- applying a coating including a binder, solvent, pigment and a plurality of pressure sensitive microchips, each pressure sensitive microchip including a pressure sensitive capacitor on a semiconductor substrate, to a substrate surface for a touch screen;
- projecting an image for a touch screen interface on the substrate surface for the touch screen;
- and
- calibrating the pressure sensitive microchips to features of the image for the touch screen Interface.
A system comprising:
- a coating including a plurality of pressure sensitive microchips, the plurality of pressure sensitive microchips each include a radio frequency (RF) antenna and are randomly dispersed and embedded in a binder for disposal on an exposed surface, the plurality of pressure sensitive microchips being calibrated to features of a touch screen interface projected onto the coating, wherein the plurality of pressure sensitive microchips have two-way communication with each other via the RF antennas and the plurality of pressure sensitive microchips are calibrated along a path to communicate with adjacent microchips from the plurality of pressure sensitive microchips;
- and
- a processor configured to activate one of the features of the touch screen interface when one of the plurality of pressure sensitive microchips corresponding to that feature is pressure activated.
