Haptic technology allows users to "feel" buttons on a touch-screen device by providing localized feedback when users' fingers touch button or control areas. A patent application filed in late March showed Apple's version of haptic technology, a process that would use piezoelectric actuators under the display to provide feedback.
A new patent application, uncovered by Patently Apple, shows that Apple is taking its haptic inquiry a step further. Apple's new displays for touch-screen devices would be flexible, allowing for a layer of the screen to actually raise itself when a button or control area is available for use.
This multitiered haptic system would allow for an even smoother user experience, especially for users who are visually impaired.
