A Webcam-Based Adhd Screening Tool using Eye-Tracking and Behavioral Tests

Attention-Deficit Hyperactivity Disorder, commonly abbreviated as ADHD, is a neurological disorder commonly associated with restlessness, difficulty maintaining attention spans, and difficulties maintaining interpersonal relationships [1]. Screening for ADHD is difficult and costly, and a more accessible and affordable option for getting tested for ADHD is necessary. As such, we created the website named NeuroGaze, which offers a non-intensive way to get tested for ADHD [2]. It utilizes the user’s webcam to use eye-tracking software across multiple tests. Three tests are employed by the website. First, a visual attention go/no-go test will generate 10 images for a user and they must only interact if they spot a certain image. Second, a continuous inhibition CPT (continuous performance test) will display random characters on a screen and the user is tasked with interacting with all non-’X’ characters [4]. Lastly, an interference test will have the user read a passage with distractions intermittently appearing, focusing on eye-tracking movement results. A screening survey follows, and the test concludes with the results screen with a potential diagnosis. To test our website’s accuracy, we created an experiment involving 12 individuals, half of which had ADHD [3]. Testing showed that our website is 75% accurate in its diagnoses, which leaves a solid foundation to further iterate on in the future.
