This 3D gesture reference design is a solution that can detect the position (x, y, and z coordinates) of a hand in space using Renesas' capacitive touch solution. The position of a hand up to 200 millimeters above a panel surface is converted to x, y, and z coordinates. Moreover, since sensing of coordinate data can be carried out at high speed, gestures (up and down, right and left, and front and behind) and simple pattern recognition can be used to operate a device.
