Motion gesture sensing device and vehicle-mounted unit manipulation system having same

A motion gesture sensing device comprising:

• a sensing board including an electrode pattern forming a sensing space with an electric field on a front side of the electrode pattern and detecting a change in the electric field in response to a motion of a user in the sensing space;
• a gesture determination board determining a gesture of the user on the basis of the change in the electric field detected in the sensing space;
• and
• a main board supporting an execution of a specific function of a unit corresponding to the determined gesture,
• wherein the electrode pattern comprises:
• a transmitter electrode disposed in a central region of the sensing board and forming the sensing space;
• and
• receiver electrodes disposed along upper, lower, left, and right outer edges of the sensing board and detecting the change in the electric field,
• wherein the transmitter electrode comprises four elongated sub-transmitter electrodes arranged in a rectangular central region of the sensing board, the four elongated sub-transmitter electrodes extending in parallel with each other, and disposed at equal distances from upper and lower receiver electrodes,
• wherein a first pair of the four elongated sub-transmitter electrodes located in outer portions of the rectangular central region with respect to left and right receiver electrodes are disposed closer to the left and right receiver electrodes than a second pair of the four elongated sub-transmitter electrodes located in a central portion of the rectangular central region,
• wherein the first pair of the four elongated sub-transmitter electrodes located in the outer portions have a stronger output than the second pair of the four elongated sub-transmitter electrodes located in the central portion.
