A new Apple patent filing shows an iPod-like device that would boast a display on one side and a touch-sensitive surface on the other. Apple’s summary of the patent reads: “An electronic device uses separate surfaces for input and output.
One of the surfaces (e.g., the bottom) includes a force-sensitive touch-surface through which a user provides input (e.g., cursor manipulation and control element selection). On a second surface (e.g., the top), a display element is used to present information appropriate to the device’s function (e.g., video information), one or more control elements and a cursor.
The cursor is controlled through manipulation of the back-side touch-surface. The cursor identifies where on the back-side touch-surface the user’s finger has made contact.” [via Gizmodo].
