Apple’s patent application for dual-sided track pad
Title: DUAL-SIDED TRACK PAD
Abstract:
A system including a capacitive array element capable of sensing touch from either side is described. A connected processor unit, either in the device or the host system, may be adapted to interpret signals from the capacitive array element as a cursor or view movement with six degrees of freedom. The track pad device may include a display element and the capacitive array element may be translucent. The display element and the array element may be configured with respect to each other, where different configurations can be associated with different operating modes. For example, when the array element lies over the display screen so that the display screen is viewable through the array element, the array element can function as a touch screen. In another configuration, the array element may generate signals indicating a user’s touch from one or the other or both sides of the array element.
