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.

Abstract: A flexible capacitive touch sensing device comprising a first, a second sensing region and a capacitance detection circuit. Each of the first, second sensing region comprises: flexible material; and electrodes, in or on the flexible material. Capacitance sensed by the capacitance detection circuit is used for detecting if an object causes capacitance variation to the first sensing region and the second sensing region. The first sensing region comprises a first side region with a first side which is adjacent to a second side of the second sensing region Shapes of the electrodes are changeable after provided on the flexible material. The electrodes are overlapped in normal directions of the first side region and the second side region. An angle which is not 0 degree exists between the electrodes which are overlapped. Such flexible capacitive touch sensing device can be applied to generate a HOD device with different sizes.
