Apple Display Patent Uses Infrared Light to Detect Touch Pressure

By Gary Cutlack on at

A simpler method of measuring how hard children are jabbing their fingers at the "BUY" button inside tawdry free-to-play applications may be on the way from Apple, after patents for a new pressure sensitive touchscreen were unearthed.

The actual patent says Apple's sensitivity system "determines applied force by the user's finger within infrared transmit lines on a touch device," which would make pressure sensing much less a bulky proposition. The concept is quite straightforward, with Apple's engineers outlining a way of positioning IR sensors beneath the display that emit high frequency light. How much of this bounces back lets a future Apple touchscreen decide how hard it's being pressed or licked. Imagine the possibilities. [Apple Insider]
