Eye movement as a predictor of cognitive ability

With aging population, neurodegenerative disorder is becoming health issue and hence early screening tools to prevent adverse effects are critical. Early screening may help to detect such disorder at a nascent stage which can be clinically addressed thereby delaying its progression. With technological progress, brain scanning can identify such disorders. However, access to such tools are restricted due to high cost and necessity of technical skills to operate that are limited to specialized health centers. Tracking one's eye movement in response to a visual task can be cost-effective alternative for developing screening platform. Motivated by this, we have designed computer-based visual tasks and exposed participants to these tasks. Our system captured one's eye movement to quantify gaze in terms of reaction time and % correct fixations in response to visual stimuli presented on computer monitor. The preliminary results of our experimental study with 10 healthy participants are promising.
