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.
EyeTechDS Inc.’s 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.
What if your car could tell if you’re happy, sad, or too tired or impaired to drive?
EyeTechDS Inc. visual tracking software uses occulometrics track eye movement and pupil dilation gauging the drivers attention or lack thereof while driving. Noldus Facial recognition software recognizes a smile or slack facial expressions, head pose, eye perclose and many other useful metrics which will be helpful for ADAS. Results are graphed to show a drivers attention and emotions while behind the wheel.
Noldus “FaceReader automatically analyzes 6 basic facial expressions, neutral, contempt, and boredom, interest, and confusion.”1 Widely used in marketing application FaceReader is able to “quickly gain insight into the effects of different stimuli.”1
Potential application include luxury auto manufacturers who will be able to accurately gauge a level of satisfaction and distractions from the driving experience, while restricted drivers could have more than a simple breathalyzer restricting their cars from starting. Further advancements in automated driving could tell the car when it's time to take over driving to deliver passengers to a safe location eliminating falling asleep behind the wheel.

Technology is changing everything from urgent medical diagnostics, how we interact with our screens (Smart Phone, PC, or TV) or monitoring our level of awareness and emotional state while driving our cars. EyeTechDS Inc. will demonstrate new ways of testing for concussions from the sidelines using a VR headset, how cars can read our cognitive and emotional state, and new ways to control our screens using our touch-free eye control technology.

About EyeTech Digital Systems, Inc
Founded in 1996, EyeTech designs algorithms, hardware, and software for eye tracking systems used in speech devices which help paralyzed individuals communicate and control their computer hands-free using only eye movements. The technology is now being incorporated into emerging industrial and consumer applications in medical diagnostic solutions for neurological testing, simulation and training solutions, vehicle safety, security, gaming, wearable VR/AR solutions and more.
Concussion is a traumatic brain injury that affects your brain function. Effects are usually temporary but can include headaches and problems with concentration, memory, balance and coordination.1
Current scientific methods to quickly assess for a potential concussion include the King-Devick Test (K-D Test) of rapid number naming which requires eye movements as well as attention, language, concentration and other areas whose functions correlate with suboptimal brain function.2 Eye tracking technology combined with the K-D Test brings more quantitative tools to brain injury management.3 Utilizing EyeTechDS Inc. technology, the King-Devick Eye Tracking System’s real-time automated data measurement and visualizations of eye movements provides a detailed assessment of oculomotor function during performance of the King-Devick Test allowing for quantification of injury severity and recovery progression.4
