Abstract: A pressure sensing device, comprising: a frame work; a capacitive pressure sensor layer, surrounding the frame work; a capacitive touch sensor layer; and a flexible material layer, located between the pressure sensor layer and the touch sensor layer and surrounding the capacitive pressure sensor layer. The capacitive touch sensor layer is above the flexible material layer when the capacitive pressure sensor layer is below the flexible material layer. The capacitive touch sensor layer has a first driving electrode and a first sensing electrode. The capacitive pressure sensor layer has a second driving electrode and a second sensing electrode. A 3D gesture control system and a vehicle control system applying the pressure sensing device are also disclosed. Via the pressure sensing device, the 3D gesture control system and the vehicle control system can generate control commands according to a touch or a pressure provided by a user.

Abstract: An HOD device, comprising: a framework; covering material, covering the frame work; at least one conductive region, provided on or in the covering material; wherein the conductive region is coupled to a capacitance detection circuit or a predetermined voltage level. The HOD device can be a vehicle control device such as a steering wheel. The conductive region comprises conductive wires which can be threads of the covering material. By this way, the arrangements of the conductive wires can be changed corresponding to the size or the shape of the frame work or any other requirements. Also, the interference caused by unstable factors can be improved since the conductive wires can be coupled to a ground source of the vehicle to provide a short capacitance sensing path.
