One of the challenges of the early detection of dementia is the lack of a simple screening method to detect cognitive impairment. A simple non-invasive screening test, when established, will greatly motivate patients to receive the test and thus bring the full benefits of early diagnosis.
Eye tracking-based cognitive assessment (ETCA) is a method with scientific and medical foundation that is accessible to everyone, enabling patients to make the best of early diagnosis.
The assessment uses data obtained from biological movements, namely, of the eyes, toward images or videos, such as the percentage of fixation duration on the correct images, percentage of successful gaze detection, and gaze plot statistics and graphs. This innovative method enables the non-invasive, simple, objective, and quantitative determination of cognitive functions. Users simply look at the monitor screen and follow the instruction displayed to obtain their cognitive assessment.

“Cognitive assessment simply by looking” method
based on the eye movements
Cognitive task images
(question / answer)
displayed on the monitor.
Continuous recording of movements of the
subject’s eyes
looking at the task images
(eye tracking)
Scoring based on the eye fixation rate
on a specific element
(ex. correct image)
This technology is a fruit of the project “Reduction of burden to the social system by developing a simple cognitive screening system using eye tracking technology”, which was launched in the framework of the Program for Creating STart-ups from Advanced Research and Technology (START)of the Japan Science and Technology Agency (JST). To implement the technology, Ai-BrainScience Inc. was established in November 2019 as a venture originated from Osaka University.
