Introduction to Wireless Gesture Sensors (Use Cases for Analog Devices Products) | NEXTY Electronics, a trading company for electronic components and semiconductors.

Wireless Gesture Sensor Overview

NEXTY Electronics, having previously developed optical gesture sensor solutions, has now created a wireless gesture sensor to meet high market demand.
Its control board interface supports BLE and Wi-Fi systems, allowing connection to applications using similar communication methods.
We developed this wireless gesture sensor to handle the growing demand for remote control of home appliances and display products.
Like our optical gesture sensor, it uses an infrared LED-based gesture recognition system, enabling the addition of gesture functionality at a lower cost than infrared or camera-based solutions.

Wireless Gesture Sensor Evaluation Kit

Board Size
Wireless Board: 28 × 100mm
Sensor Main Board: 180 × 180mm
Wireless Board Communication Interface: Wi-Fi / BLE
Features
Up to 120 LED boards can be inserted into this board. While the required gesture patterns and shape recognition depend on the customer's specific system, LEDs can be flexibly placed for evaluation purposes.

About Shape Recognition

NEXTY Electronics' developed software can extract shape features even from low-pixel sensor data to estimate shapes.

Use examples include system activation or mode changes based on specific shape detection.
Another use example is implementing a rock-paper-scissors function in amusement or arcade games.
