Apple Patents Hover-Sensing Multi-Touch Display for Macs and iPhones

The United States Patent and Trademark Office today published a patent filed by Apple last March, which details how inline proximity sensors could be used in tandem with a touchscreen display to detect non-contact hover gestures (via AppleInsider). The patent, titled "Proximity and multi-touch sensor detection and demodulation", reveals how photodiodes or other proximity hardware work in parallel with traditional multitouch displays to extend user interaction beyond the screen surface. One embodiment of the patent describes a capacitive sensing element, using a range of proximity sensors and an LCD display, that would let users deploy gestures above a traditional keyboard, resulting in a "virtual keyboard". With multiple proximity arrays deployed on every touch sensor or pixel of the panel, the system can detect a finger, palm or other object hovering over the display surface. The detected motion is then translated to a GUI by which users can "push" virtual buttons, trigger functions without physical touc
