Overview
Description
The 3D Gesture reference design detects the position of a hand in space by measuring its x-, y-, and z-coordinates using Renesas' Capacitive Touch Sensing Unit (CTSU). The system can track hand movement up to 200mm above the panel surface and convert it into precise spatial coordinates. High-speed coordinate sensing enables reliable gesture recognition, such as up and down, left and right, and forward and backward motions, as well as simple pattern recognition for intuitive device control.
Features
- Based on Renesas' high‑sensitivity, noise‑tolerant capacitive touch technology
- Touch sensing through any non‑conductive material, enabling hidden or embedded designs (e.g., behind walls or panels)
- Enables system control and gesture operation using a high‑performance, low‑power 32‑bit microcontroller with integrated touch IP
- Supports combined use of gesture recognition and capacitive touch buttons
- Compliant with IEC 61000‑4‑3 Level 3 immunity standards
