Abstract
An input device configured to communicate with a computing device includes at least one keycap, a support mechanism operably connected to the keycap and configured to move the keycap from a first position to a second position, a feature plate operably connected to the support mechanism, and a sensing member. The sensing member is configured to detect at least one of a change of position of the at least one keycap, a speed of the at least one keycap, an amount of force applied to the at least one keycap, or a location of a finger. The sensing member may be a capacitive sensor. In some embodiments, the input device may not include the support mechanism and the sensing member may be configured to detect the location of a finger regardless whether or not the keycap moves.
