from appleinsider.com: Apple is famous for its pioneering touchscreen devices, but a new patent shows the company has also dabbled behind the scenes in touch-sensitive buttons that would be able to distinguish between accidental activation and an actual finger press. The concept comes from a patent continuation published this week by the U.S. Patent and Trademark Office and discovered by AppleInsider. Entitled “Configurable Buttons for Electronic Devices,” Apple’s invention describes a physical button with an associated touch sensor that could detect when a user’s finger is touching it.
