Abstract
A computing device configured detect a user input. The computing device includes a processor, a touch interface in communication with the processor and configured to detect a touch signal corresponding to an object approaching or contacting a surface, and at least three force sensors in communication with the processor and configured to detect a force signal corresponding to an object exerting a force on the surface. In response to the force the at least processor determines a force centroid location and the touch signals are processed by the processor by analyzing the force centroid location.
