Geneva, July

– STMicroelectronics (NYSE: STM),
a global semiconductor leader serving customers across the spectrum
of electronics applications, has unveiled its latest FlightSense™
Time-of-Flight (ToF) multi-zone sensor. Delivered together with a
suite of valuable software algorithms, the combination provides a
turnkey solution for user detection, gesture recognition, and
intruder alert, specially designed for the PC market.
ST’s FlightSense multi-zone sensors continuously scan their
field of view to map the scene and gather intelligence without
using a camera or recording images. By using 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 can detect
multiple targets in 64 (8x8) zones within a wide 61-degree field of
view. The sensor comes with Presence Premium PLUS, ST’s proprietary
third generation of algorithms dedicated to PC applications,
supporting its advanced and innovative features 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 VL53L5CP and Presence Premium PLUS software are optimized
for PC applications and supported in Windows® 11. PC designers can
thus implement innovative features including smart power
management, enhanced security, and touchless user interaction. ST’s
presence solution has been the pioneer to enable wake-on-approach
and walk-away lock, which enable a seamless “always-on” user
experience while maximizing battery-energy savings. Automatic and
immediate walk-away lock also prevents unauthorized access and data
protection while the user is away.
In addition, multi-human detection (MHD) senses other people in
the field of view and analyzes their position and movements to
assess security risks such as “shoulder surfing.” In relevant
situations, the system alerts the user.
Another breakthrough innovation in the VL53L5CP is robust
touchless gesture sensing, which allows the user to control PC
applications without touching the screen, keyboard, or mouse. The
sensor can detect directional swipes and taps, as well as level
adjustments. With access to such information, developers can easily
implement instructions such as next or previous slide/song/video,
play/pause, and volume control.
Global technology powerhouse and the world’s leading PC company2
Lenovo is integrating ST’s presence solution in select laptops.
Zhaochun Ma, Lenovo Vice President of Consumer and SMB Notebook
Development Center, Intelligent Devices Group commented, “Today’s
flexible, mobile working lifestyles demand privacy and ease of use
to maximize productivity. That’s why we’ve integrated ST’s presence
solution based on camera-free ToF sensing into Lenovo PCs. From
logging into and locking one’s device hands-free based on human
presence detection to using hand gestures to swipe content, we’re
making Lenovo PCs smarter and more adaptive.”
ST’s Presence Premium PLUS software also enables PC designers to
develop custom AI applications in Windows, leveraging the VL53L5CP
sensor’s 8x8 multi-zone data to sense user intent, with continuous
presence detection. In addition, dynamic programming of the
VL53L5CP’s key parameters from Windows allows the end user to
personalize parameters such as timing and lock/wake distances.
By enabling these features using non-vision-based ToF technology
rather than the PC’s webcam, the VL53L5CP enables superior
differentiation in several respects. With no image, it eliminates
any privacy concerns. The sensor is always on, hidden behind the
bezel, thereby removing dependence on the webcam shutter position.
In addition, the sensor integrates a 940nm VCSEL infrared light
emitter, invisible to human eyes, which ensures full performance in
the dark or low-light conditions. In contrast, cameras need a
dedicated power-hungry LED to illuminate the scene.
ST’s FlightSense technology outperforms several other techniques
used for human detection. These include traditional infrared
sensors, which do not measure distance and are affected by the
color and reflectance of detected objects. Ultrasound is sensitive
to noisy environments and may affect pets’ hearing. Radar requires
very complex software development on top of power-hungry signal
processing.
“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.”
The VL53L5CP FlightSense multi-zone ToF sensor is in volume
production and available now with the Presence PREMIUM PLUS
algorithms. Please contact your ST sales office for pricing options
