Abstract
Techniques for providing multi-user multi-touch projected capacitive touch sensors are disclosed herein. Some embodiments may include a method that includes receiving a first sense signal from a first sensing array, the first sensing array configured to provide the first sense signal indicating a first touch on a first touch surface of a touch substrate as well as receiving a second sense signal from a second sensing array, the second sensing array configured to provide the second sense signal indicating a second touch on a second touch surface of a second touch substrate occurring concurrently to the first touch. The method may further include determining whether the first touch and the second touch share at least one anti-ghost. The method may also include associating the first touch and the second touch with a common touch entity in response to determining that the first touch and the second touch share the at least one anti-ghost.
