Apple Investigating Keyboards with Proximity Sensors, Tactile Feedback
Posted on May 12, 2011 by vincent oliver
A recent patent application discovered by AppleInsider reveals that Apple is showing interest in creating a keyboard that can provide tactile feedback to users using proximity sensors and air vents on individual keys.
The patent filing describes a system that would “flow air from the input device,” perhaps through openings in the surface of an individual key on a keyboard. This would provide tactile feedback to the user before they make physical contact with the key surface.
This air pressure could be used to apply air pressure against a user’s fingertips, giving tactile feedback even though the key may not move as much as a key on a more traditional keyboard.
