1. A method for forming a touch screen comprising:
- applying a liquid coating including, suspended therein, a plurality of radio frequency (RF) sensitive microchips to a substrate for a touch screen, each of the microchips including an antenna structure and a memory containing a chip identification;
projecting an image for a touch screen interface on the substrate for the touch screen;
calibrating the radio frequency sensitive microchips to features of the image for the touch screen interface; and
activating the radio frequency sensitive microchips that are calibrated to the features of the image to activate said feature of an interface.

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.

8. A system for a touch screen interface comprising:
-
a projector for projecting at least one light image onto a liquid coating that is applied to a touch screen substrate that includes, suspended therein, a plurality of touch activated microchips, each including an antenna and a memory containing a chip identification, wherein the at least one light image includes a touch screen image including activation fields for a function; an image calibrator that calibrates touch activated microchips in the coating to said at least one light image projected; a receiver for receiving signal from the touch activated microchips when said feature of the light image is activated; an activated microchip to selected feature actuator to correlate a signal received by the receiver from a touch activated microchip that a user of the touch screen interface has selected the activation field for the function; and a transmitter of an activated feature signal from the touch activated microchips that sends a signal to a computer interfacing with the touch screen interface instructing that said activation field for the function has been selected. - View Dependent Claims (9, 10, 11, 12)
