Apple has filed a patent for a keyboard that uses proximity sensors and tactile feedback to detect user input.

A concept design for a new type of keyboard was revealed this week, when a patent application filed by Apple was made public. The design aims to solve the problem of input quality with keyboards getting smaller and more compact. Apple’s proposal would improve the typing experience for the user so they aren’t negatively impacted by thinner keyboards and tiny keys.

Proximity sensors in each key would detect which one you are about to press and air would flow from the device to provide you with tactile feedback. Apple also mentions a pneumatic system that pulls a key down in response to detecting that a person has selected it. Using this method, you would hardly have to touch the key in order for it to be pressed.
