STMicroelectronics intros advanced human presence detection solution

STMicroelectronics has introduced a new Human Presence Detection (HPD) technology for laptops, PCs, monitors and accessories, delivering more than 20% power consumption reduction per day in addition to improved security and privacy.

ST’s proprietary solution combines market-leading FlightSense Time-of-Flight (ToF) sensors with unique AI algorithms to deliver a hands-free fast Windows Hello authentication; and delivers a range of benefits such as longer battery lifetime, and user-privacy or wellness notifications.

“Building on the integration of ST FlightSense technology in more than 260 laptops and PC models launched in recent years, we are looking forward to see our new HPD solution contributing to make devices more energy-efficient, secure, and user-friendly,” said Alexandre Balmefrezol, Executive VP and GM of the Imaging Sub-Group at STMicroelectronics.

“As AI and sensor technology continue to advance, with greater integration of both hardware and software, we can expect to see even more sophisticated and intuitive ways of interacting with our devices, and ST is best positioned to continue to lead this market trend.”

Florian Domengie, Principal Analyst, Imaging at Yole Group, noted: “Since 2023, 3D sensing in consumer applications has gained new momentum, driven by the demand for better user experiences, safety, personal robotics, spatial computing, and enhanced photography and streaming.

"Time-of-Flight (ToF) technology is expanding beyond smartphones and tablets into drones, robots, AR/VR headsets, home projectors, and laptops. In 2024, ToF modules generated $2.2 billion in revenue, with projections reaching $3.8 billion by 2030 (9.5% CAGR). Compact and affordable, multizone dToF sensors are now emerging to enhance laptop experiences and enable new use cases.”

Fifth generation turnkey ST solution
By integrating hardware and software components by design, the new ST solution is a readily deployable system based on FlightSense 8×8 multizones Time-of-Flight sensor (VL53L8CP) complemented by proprietary AI-based algorithms enabling functionalities such as human presence detection, multi-person detection, and head orientation tracking. This integration creates a unique ready-to-use solution for OEMs that requires no additional development for them.

This fifth generation of sensors also integrates advanced features such as gesture recognition, hand posture recognition, and wellness monitoring through human posture analysis.
