WHITE BOARD OPERABLE BY VARIABLE PRESSURE INPUTS
First Claim
1. A dry erase whiteboard, comprising:
- a) a substrate having a surface;
b) a pressure sensitive composite layer supported by the surface of the substrate, the pressure sensitive composite layer having an electrical characteristic that is variable in response to application of pressure to a contact surface of the composite layer; and
c) a control system coupled to the composite layer to generate different input commands for a computer system based on varying values of the electrical characteristic resulting from the application of differing pressure applied to the contact surface.

Abstract
A dry erase whiteboard, or other writing or projection surface assembly, is formed from a substrate having a surface and a pressure sensitive composite layer supported by the surface of the substrate. The pressure sensitive composite layer has an electrical characteristic that varies in response to the application of pressure to a contact surface of the composite layer. A control system coupled to the composite layer generates input commands for a computer system based on varying values of the electrical characteristic resulting from the application of pressure to the contact surface. Different input commands may be generated based on the number of currently applied pressures, as well as the degree of applied force associated with each different touch.
