Future Devices Will Have Touch-Sensitive Cases

In a new patent, Apple has revealed plans for new devices without any buttons at all: using technologies like capacitive sensing, resistive sensing, and surface acoustic wave sensing, the device's case would respond to touch and hand gestures. "The touch sensing devices may for example be selected from touch panels, touch screens or touch sensitive housings," according to the patent, entitled "Hand held electronic device with multiple touch sensing devices". You'd be able to control an iPhone with the same hand you hold it in, and secure it to your unique hand print.
