Prophesee’s partner Zinn Labs announces event-based eye-tracking system for AI-enabled smart frames and VR/MR systems

Breakthrough event based eye tracking system leverages ultra-low-power, low-latency of event-based vision sensors from Prophesee enables new levels of intuitive, seamless user experiences

MENLO PARK, California – January 30, 2024 – Today, Zinn Labs is introducing the industry’s first event-based eye-tracking system for VR/MR headsets and smart frames. The core enabling feature of event-based sensing is the faster and more efficient capture of the relevant signals for eye tracking.

Kevin Boyle, CEO of Zinn Labs, explains, “Zinn Labs’ event-based gaze-tracking reduces bandwidth by two orders of magnitude compared to video-based solutions, allowing it to scale to previously impractical applications and form factors.”

The low compute footprint of Zinn Labs’ 3D gaze estimation gives it the flexibility to support low-power modes for use in smart wearables that look like normal eyewear. In other configurations, the gaze tracker can enable low-latency, slippage-robust tracking at speeds above 120 Hz for high-performance applications.

Gaze-tracking Applications

Smart eyewear is a rapidly emerging category that can serve as an always-there portal to access generative AI. The attention signal provided by gaze seamlessly connects AI output to the user’s intentions in a variety of application demos provided by Zinn Labs.

As AR and MR computing devices move toward increasingly more intuitive user interfaces, gaze tracking is a prerequisite for several component technologies. For example, gaze is the most natural method of interacting with the digital environment. Zinn Labs leverages the Prophesee GenX320 sensor to offer a high-refresh-rate and low-latency gaze-tracking solution that makes an attractive solution for those looking to push the boundaries of responsiveness and realism of head-worn display devices.

Zinn Labs DK1 available soon

The Zinn Labs DK1 Gaze-enabled Eyewear Platform is a development kit equipped with a binocular event-based gaze-tracking system and outward-facing world camera and is powered by Zinn Labs’ 3D gaze estimation algorithms. The DK1 is equipped with Prophesee GenX320 event-based Metavision® sensors, the smallest event-based sensors on the market.

“Frame-based acquisition techniques don’t meet the speed, low latency, size and power requirements of AR/MR wearables and headsets that are practical to use and provide a realistic user experience. Our GenX320 was developed specifically with these real-time and processing efficiency needs in mind, delivering the advantages of event-based vision to a wide range of products, such as those that will be enabled by Zinn Labs’ breakthrough AR/MR platform,” said Luca Verre, CEO and co-founder of Prophesee.

The DK1 supports sub-1°, slippage-robust gaze tracking accuracy and runs at 120 Hz with 10 ms end-to-end latency. The development kit comes with demo applications, such as the wearable AI assistant featured here, and can be used for performance evaluation or customer proof-of-concept integration projects.

Zinn Labs will be presenting the technology and demonstrating the DK1 at SPIE AR | VR | MR 2024 on January 30th and 31st in San Francisco, CA. Check out for more information or contact to inquire about development kits and licensing.


Zinn Labs, Inc. designs pupil and gaze tracking systems for head-worn devices, as well as novel user interfaces that only gaze can enable. Zinn Labs’ technologies combine cutting-edge computer vision research with a deep understanding of the human visual system and how user attention, captured through gaze, can bring a vision-first neural interface to a new generation of consumer devices.
