VIVA develops VCSEL smart glasses
The VIVA project is developing photonics-enabled smart glasses that use VCSEL-based eye tracking without cameras.
An EU-funded research project is developing a new generation of smart glasses that use photonics-based eye tracking to create more intuitive and privacy-focused wearable devices.
The project, called VIVA, is using VCSEL technology to monitor eye movements without cameras, enabling lightweight smart glasses capable of responding to a user’s gaze in real time.
The system is designed to support applications in automotive safety, industrial environments and future consumer wearables.
Unlike conventional eye-tracking systems that rely on cameras and image processing, the VIVA platform uses laser-based sensing to detect microscopic eye movements through reflected light signals.
The approach aims to reduce hardware size, improve wearer comfort and enhance privacy by avoiding image capture altogether.
One of the project’s first demonstrators includes auto-focal smart glasses that automatically adjust lens focus depending on where the user is looking.
The system is designed to recognise reading behaviour and other gaze patterns with high-speed detection and low false-trigger rates.
The consortium is also integrating meta-optics and fast signal-processing technologies to support compact, low-power operation suitable for all-day wearable use.
Coordinated by Bosch Sensortec, the VIVA project brings together partners across Europe specialising in photonics, sensing, optics, AI and advanced manufacturing.
The initiative reflects growing interest in photonics-enabled human-machine interfaces and next-generation wearable sensing technologies.
