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 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.

This Reference Design is a solution combines multiple capacitive proximity sensors to detect hand gestures such as holding for a certain period of time or moving a hand over from the electrode to other electrode for realizing simplified gesture operations.

Features

  • Based on Renesas' high sensitivity, noise-tolerant capacitive touch solution
  • Recognize the position of a hand up to 200mm above a sensor
  • Up to 1mm accuracy
  • High noise tolerance and works with shielding
  • Sensing can be carried out with any nonconducting material - thus can be embedded inside a wall, etc.
  • Realize system control and gesture operation for your product using a high-performance, low power 32-bit microcontroller and touch IP
  • Also possible to use gestures in combination with touch buttons
  • Support for IEC 61000 4-3 Level3

Can gesture recognition be used with infrared (pyroelectric sensor), sound wave devices, or cameras?

e-AI x 3D gesture recognition

You can develop a gesture application that reacts "by anyone's hand" without any specialized skills just by actually performing the gesture that you want AI to remember on the capacitance sensor.
