Abstract
In various embodiments, a touch surface may comprise multiple individual sensors, each of which is capable of mechanical deflection in a direction parallel to the surface, with the device using the touch surface being able to detect such deflection in each sensor. With this capability, the device may be able to detect intended movement of a touch over the touch surface even if no additional sensors are activated by that movement. Such sensors may be useful for detecting very small motions, and may be especially useful for motions in which the shape of the user's thumb results in the same touch area being in contact with the thumb even though the thumb is executing an extension or retraction movement.
