He invented the capacitive touch screen. The resistive touch screen was in many devices long before smart phones (bank machines being a common example). The resistive touch screen was fine for those applications but it was useless for the smart phone (too slow to respond). The capacitive touch screen’s first killer app was the smartphone, namely the iPhone.
