Smart glasses are moving closer to becoming everyday companions. But for truly intuitive interaction, the device needs more than an understanding of what is around the wearer. It also needs to know where the wearer is looking.
Eye tracking provides this information by illuminating the eye with infrared light and using inward-facing cameras to determine gaze direction. This can support intuitive user interaction and, in AR glasses, help reduce computing and power requirements through techniques such as foveated rendering.
A design blueprint for immediate implementation
Smart glasses manufacturers can accelerate the product development process by adopting a ready-made design template for safe eye tracking. Ganzin Technology's Aurora IIS eye tracking reference design combines the AS1181 driver IC with SFH 4030B LEDs to enable reliable eye tracking even outdoors in bright daylight. The reference design features synchronized binocular camera driving, complemented by additional driver-based eye-safety protection in the AS1181. This solution powers Ganzin Technology's AI glasses reference designs and is ready to enable next-generation partner platforms, such as those from its ODM partners, including Jorjin and Quanta.
System expertise for the next generation of smart glasses
Reliable eye tracking requires more than individual components. Infrared illumination, driver electronics, cameras, and algorithms must work together within the tight constraints of smart glasses. ams OSRAM combines compact infrared emitters and dedicated driver technology with deep optical and system expertise, helping manufacturers address key design challenges including size, power consumption, performance, and eye safety.
