Eye Tracking in Tallahassee, FL
What is eye tracking?
Eye tracking is about where we look, what we look at, how much time we spend looking, how our pupils react to different kinds of visual stimulation and when we blink. Put most simply, eye tracking refers to the measurement of eye activity. Over the past 30 years, eye tracking has become an increasingly popular tool in clinical practice and research for understanding brain function and eye health.
How does eye tracking work?
Eye tracking implies the recording of eye position (point of gaze) and movement on a screen or in environments based on the optical tracking of corneal reflections. Infrared technology illuminates the eyes, creating a glint. Sensors take the image of the eye at high speed, and in real time provide X and Y coordinates for each eye.
What are the benefits of eye tracking?
Eye tracking technology has been used to examine clinical conditions and provide indicators for Autism Spectrum Disorder, Attention Deficit Hyperactivity Disorder, Parkinson’s disease, essential tremors, stroke, small vessel ischemia, reading disorders, dyslexia, binocular vision issues such as convergence, divergence, amblyopia, depth perception; drug and alcohol levels, concussion, and brain injury.
Eye tracking software is highly specific, capturing pictures of the eye many times (30-1000) a second to provide output and assist with a diagnosis. Data output from eye tracking is quantitative, allowing both the practitioner and patient to receive numbers that can then be compared to a general population as well as to the individual patient over time.
How is eye tracking important in everyday use?
Think of all the ways that you will use your eyes today. Driving a car, reading a book, surfing the internet, searching the aisles of a store, playing a video game, completing a training exercise, watching a movie, or looking at pictures on your mobile device.
Whether we realize it or not, these are all applications of eye tracking. With very few exceptions, anything with a visual component can be eye tracked. By using eye tracking we can not only improve our everyday lives but provide early diagnosis for many neurological disorders which can lead to earlier recovery.
