Abstract
Described are methods and devices including a touch sensor layer configured to receive touch input and a force sensor layer stacked with the touch sensor layer, the force sensor layer includes an array of force sensors configured to receive force input. The force sensor array includes individual force sensors. Specific sensors of the disclosed force sensor array are associated with specific locations of the touch screen to add information that can be used to decipher which key is actually being pressed and may avoid falsing. Both a touch signal and a force signal are utilized to determine the validity of a user touch input. In one embodiment each force sensor may operate independently of the others. Particular embodiments are described that utilize a coarse grid to determine valid touch inputs and that make a determination of a centroid location based on a plurality of force sensors to determine valid touch inputs.
