A very unique Apple patent has been discovered which has started rumours of Apple developing a new a new, low-profile keyboard equipped with perforated keys. The Patently Apple website has discovered the Apple Patent which explains a new design that uses air pressure and proximity sensors.
Once a users finger is registered by the new device to be above a key the keyboard then emits a light stream of air to provide the user with pre-press feedback. The Apple Patent also describes that flowing of air could also be implemented in a virtual keyboard.
With the virtual keyboard “each key location is merely a defined region on a solid surface, where contact with that surface region will generate a defined input signal.” as such the new virtual keyboards may not have any moveable surfaces at all. More information and a full run down of the newly discovered Apple Patent can be found over on the Patently Apple website.
