1. A method for forming a touch screen comprising:
- applying a coating including a plurality of pressure sensitive microchips to a substrate for a touch screen;
projecting an image for a touch screen interface on the substrate for the touch screen;
calibrating the pressure sensitive microchips to features of the image for the touch screen interface; and
activating one of the features of the image by pressure activating the pressure sensitive microchips that are calibrated to that feature.

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.

10. A microchip comprising:
-
a capacitor sensor formed on a substrate, the capacitor sensor detecting changes in capacitance associated with a pressure activation; a radio-frequency (RF) antenna formed on the substrate; and a memory coupled to the RF antenna, the memory including identification information of the microchip configured to be transmitted via the RF antenna in response to the pressure activation of the capacitor sensor. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17)
