The term "touchpad" is actually a misnomer. The capacitive touchpads in current notebooks use an electrical field to track finger positioning. It doesn't take a true touch to move the cursor-mere proximity of a finger will do it. Interlink Electronics (800-340-1331, 805-484-1331) has a new semiconductive touchpad based on the company's Force Sensing Resistor that uses physical touch to move the cursor. Interlink's VersaPad should start showing up in notebook computers later this year.
