Dual-Sided Touch Panels for iPhones, MacBooks, Tablets?
Apple introduces the idea of a double-sided translucent touch surface. This touch surface would be sensitive to touch on both sides. When placed as the bottom half of a traditional laptop...
... it could function as a multi-touch keyboard including the use of multi-touch gestures. When the user closed the laptop, however, the other side of the touch screen could act as a multi-touch overlay to the screen -- giving the device a tablet-like form factor.
Apple also explores the possibilities of incorporating a similar translucent touch pad to offer a mobile phone with similar capabilities.
