Overview
Description
The 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 sensing (CTSU) solution. The position of a hand up to 200mm 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.
The 2D Gesture reference design uses a combination of multiple capacitive proximity sensors to detect hand movements such as placing a hand over or approaching an electrode for a certain period of time, or straddling multiple electrodes, making it easy to perform gesture operations.
