EyeTech Digital Systems is excited to collaborate with Mayo Clinic in the development of the OCAT, Oculo Cognitive Addition Test. Working in oculometrics where direct physiological signs of cognitive activity have been identified, the team of scientists at Mayo Clinic’s Aerospace Medicine & Vestibular Research Laboratory (AMVRL) developed OCAT which now enables researchers to quantify and detect alterations in cognitive and oculometric performance.
Administered using a Virtual Reality (VR) headset or on a standard laptop, OCAT works by showing a test subject one stimulus at a time in specific, seemingly random locations.
EyeTech DS’ eye tracker detects where the eye is focusing from one fixation point to the next. A normal test subject will show results of straight lines efficiently connecting one fixation point to another. In a patient with signs of impairment, these lines become altered due to changes in oculometric and cognitive performance.
