<p>A resistive two sheet touchscreen that provides discrimination between objects touching the surface thereof. This is achieved by subdividing one sheet into a selected number of separated portions (50A, 50B, 52A, 52B) of selected configuration. Each of these portions is connected through a switch apparatus to circuitry for evaluating a signal on the separated portions corresponding to the position of touch. This switch can be utilized to deactivate any selected portion (50A, 50B) so that an object contacting this portion provides no signal to the circuitry. Any active portion that remains connected to the circuitry provides position information as with any touchscreen.</p> |
