Eye tracking in action: A key enabler for next-generation smart glasses

CorinnaR.

Eye tracking is one of the key sensing technologies used in AR/VR headsets and emerging smart-glass platforms. By determining where a user is looking, eye tracking enables gaze-based interaction and supports techniques such as foveated rendering, helping to reduce processing workload and power consumption.

 

In this video, Markus Zieserl demonstrates the main building blocks of an eye-tracking system for wearable devices. The demo shows how infrared illumination, LED driver electronics, and image sensing work together to illuminate the eye, capture eye images, and estimate gaze direction within the tight size and power constraints of a glasses frame.

 

Designing eye-tracking systems for smart glasses requires balancing accuracy, latency, power consumption, eye safety, and miniaturization. The video provides a practical look at the hardware technologies that make compact eye-tracking implementations possible.

    Hi Javagoza, great question!

    Eye safety is one of the most important considerations in eye-tracking design. The infrared LEDs are typically operated in very short, controlled pulses synchronized with the camera, and systems must be evaluated against internationally recognized standards such as IEC 62471 for photobiological safety. In addition, product safety standards require manufacturers to consider fault conditions and implement mechanisms that prevent exposure limits from being exceeded. ams OSRAM addresses this through dedicated eye-safety features in its IR illumination and driver solutions. As with any consumer device, manufacturers are responsible for demonstrating compliance with the applicable regulations in the markets where their products are sold.

  • Interesting video! I have to admit I know very little about eye-tracking systems, so my immediate question is about safety.

    If these glasses are constantly shining infrared light at the user's eyes, what kind of testing is performed to make sure there are no long-term health effects? Are there specific certifications or regulations that manufacturers must comply with, and do these vary between Europe, the US, and other countries?

    I'd love to learn a bit more about that side of the technology.
