Dementia is a syndrome caused by various brain-damaging diseases, with Alzheimer’s disease being the most common.  Other types includes vascular dementia, Lewy body dementia and frontotemporal dementia. Dementia is strongly associated with various oculomotor (eye movement) abnormalities. Eye tracking is emerging as a digital biomarker that objectively captures subtle changes in brain function by analysing eye movements. […]

Early diagnosis of Alzheimer’s Disease is very difficult because current diagnostic methods such as neuroimaging and lumbar puncture are quite invasive, expensive and time consuming. In contrast, eye tracking offers a non-intrusive, quick and potentially low cost screening tool. Eye movements and cognitive alterations occur at early disease stages and can be gauged through simple, […]

Why Blink Metrics? Blinks are temporary closing and opening of the eyelids and we can easily measure it with the help of eye trackers. Each blink temporarily obstructs the pupil and corneal reflections due to the closed eyelids. On average, people blink approximately 17 times per minute, which leads to missing data points for both […]

Eye Openness (EO) is a new eye tracking signal developed by Tobii for researchers, the EO represents a measure of the largest sphere that can fit between the upper and lower eyelids. The EO signal provides the basis for accurate eyelid movement detection, including different types of blinks. EO in Cognitive and Physiological processes The […]
