Abstract
Techniques for providing multi-user multi-touch projected capacitive touch sensors are disclosed herein. Some embodiments may include a touch sensor including a touch substrate with a touch surface, a sensing array, and a controller. The sensing array may be configured to provide sense signals indicating a first touch and a second touch occurring concurrently on the touch surface of the touch substrate. The controller may be configured to receive the sense signals from the sensing array and based on the sense signals, determine whether the first touch and the second touch share at least one anti-ghost. In response to determining that the first touch and the second touch share the at least one anti-ghost, the controller may be configured associate the first touch and the second touch with a common touch entity, such as an individual person.
