So we’re able to both measure your cornea and pupil thousands of times per second with the sensor.” But sometimes we receive pulses when the beam crosses the threshold between your iris and your pupil. “Sometimes we receive pulses from corneal glints, which are just like reflections off the surface of your cornea. “Any time the beam hits a part of the eye, that reflects it onto a photo detector, and we receive a pulse,” Sarkar said. Once the patient is wearing the AdHawk MindLink glasses, they launch the app and tap “start tracking.” The system is so fast it can accurately predict where a user will look next - up to 20 milliseconds before their eyes fixate - and gaze is captured 500 times per second with better than one degree of accuracy, according to AdHawk. So that’s what the MindLink is - lightweight glasses that have eye tracking.” How it worksĪdHawk replaces cameras with ultra-compact MEMS that eliminate power-hungry image processing, thereby improving speed and energy efficiency by more than twice its nearest competitor, the company claims. So we decided to just launch our own product.
“But because of the timelines, for some of the products that will ship, we don’t want to have to be at the mercy of a for our tech to actually see the light of day. “We’ve been integrating our eye tracking solution into products like VR and AR headsets,” Sarkar said. The company has 35 people, with a fabless semiconductor model, which means it designs its components and has them manufactured by contractors.

“Today, we really think of ourselves as a full stack eye-tracking solutions provider, because roughly half our company has software, working on everything from the embedded system, all the way up to applications that make use of eye tracking,” Sarkar said. The company is now augmenting its eye-tracking technology for clinical research where traditional practices have relied on qualitative measurements of eye movement as indicators of neurological health. The company raised additional money in 2019 from Samsung Venture Investment Corp., HP, Essilor International, Sony Innovation Fund, Intel Capital, Brightspark Ventures, and Silicon Valley Bank.ĪdHawk powers immersive experiences in AR and VR by enabling faster gaming, more effective training, and effortless user interfaces. And that’s really been the bread and butter for the company.” That made it very suitable for AR and VR products. “You can actually operate at very high speeds with low latencies and very little compute. “We had this solution for eye tracking that didn’t require any cameras or any heavy-duty processing,” Sarkar said. He spun the company out of the University of Waterloo with funding from Intel Capital. The sensors he studied have actuators that can operate on sub-nanometer levels of precision, and they scan a beam of light across your eye. He had a background as a chip engineer and studied MEMS in graduate school. Sarkar started AdHawk Microsystems in 2017 in Kitchener, Ontario, in Canada.
