Multi-zone ToF sensor for gesture recognition and human presence detection

26-07-2022 | STMicroelectronics | Test & Measurement

STMicroelectronics has released its latest FlightSense ToF multi-zone sensor. Provided with a suite of valuable software algorithms, the combination offers a turnkey solution for user detection, gesture recognition, and intruder alert, especially developed for the PC market.

The multi-zone sensors continuously scan their FoV to map the scene and gather intelligence with no camera or recording images. By employing ToF technology, the sensors can detect and track multiple targets, calculating at high speed their X/Y/Z coordinates and motion.

The latest VL53L5CP FlightSense multi-zone sensor is able to detect multiple targets in 64 (8×8) zones within a wide 61-degree field of view. The sensor is provided with Presence Premium PLUS, the company’s proprietary third generation of algorithms dedicated to PC applications, supporting its advanced and innovative elements and enhancing data protection. Interacting with native aspects of the PC hardware and OS, this turnkey solution is certified at the highest level by Intel.

The device and software are optimised for PC applications and supported in Windows 11. PC designers can, therefore, implement innovative features including smart power management, enhanced security, and touchless user interaction. Its presence solution has been the pioneer to facilitate wake-on-approach and walk-away lock, which provides a seamless 'always-on' user experience while maximising battery-energy savings. Automatic and immediate walk-away lock also stops unauthorised access and data protection while the user is away.

Also, multi-human detection senses other people in the field of view and analyses their position and movements to evaluate security risks such as 'shoulder surfing'. In relevant situations, the system alerts the user.

Another breakthrough innovation in the device is robust touchless gesture sensing, which enables the user to control PC applications without touching the keyboard, screen, or mouse. The sensor is able to detect directional swipes and taps, and level adjustments. With access to this information, developers can readily implement instructions such as next or previous slide/song/video, play/pause, and volume control.

“We continue to unleash more of the extraordinary potential from our FlightSense ToF technology to enable imaginative features across a full range of smart products,” said Eric Aussedat, ST’s executive VP, Imaging Sub-Group General Manager. “Now entering the fourth generation, our latest ToF sensor enables PCs to understand their users, creating a stronger connection and more rewarding ownership experience.”
