Sweden-based eye-tracking wearables specialist Tobii has announced its new Tobii Pro Glasses 3, which have better recording technology than their predecessors along with being smaller, to about the same size as a regular pair of aviator-style sunglasses.
Tobii is touting the Pro Glasses 3 as an ideal solution for outdoor visual attention research due to their small form factor packed with real world scene-recording hardware. On the matter of hardware, the glasses come equipped with four eye cameras and 16 illuminators that are built into the lenses without obstructing the wearer’s view.
As VentureBeat reports, a wide-angle camera mounted on the exterior of the glasses’ frame captures the wearer’s environment with low light capabilities and a greater field of view than the previous generation glasses, and users can control the recordings captured using both Android and Windows devices.
With their ability to record eye movements at a rate of roughly 50-100 updates per second, the glasses have a number of use cases for research, from tracking a driver’s focus in heads-up-display testing, to calculating which packaging and product designs attract the most attention for marketing purposes.
The Tobii Pro Glasses 3 differ from the company’s consumer hardware in that they are designed specifically for use by researchers and enterprises, whereas the consumer products have mostly been sold as accessories, often as a part of mixed reality headsets.
Apart from the analytical uses of the eye tracking data captured using the glasses, the technology in the hardware also allows users to control interfaces with their eyes, where a fixed gaze on a point is a signal to accept or move forward, while a change of gaze moves a cursor.
