Abstract
Touch input devices are provided with the capability of sensing a capacitive load in a two-dimensional array while also being able to sense deflection or movement of the input device in multiple different locations under an input pad. A touch input device can beneficially be used in a remote control device and can be used with multiple input buttons or platforms overlaying multiple capacitive touch input regions on a capacitive touch sensor substrate. Movement and position of a capacitive load can be tracked and calculated via output signals from a set of electrodes or other capacitance sensors with irregular shapes, with inconsistent distances from the capacitive load, and which are positioned below variable materials and material compositions. Thus, tracking gestures and taps can be detected using the capacitance sensing devices, and deflection input can be detected using switches or other actuators situated under the capacitance sensing devices.
