An Eye-Tracking Toolkit for Evaluating Memory in Epilepsy Patients Open Access

Abstract

Epilepsy affects 50 million people worldwide and has profound implications in

many facets of everyday life. For example, learning can be impaired in people with

epilepsy, as children with the disease have a higher risk for learning disabilities. Eye tracking

has been shown to be an effective measure in both assessing and improving

memory in an academic setting. In this thesis, we focus on assessing memory, an

important aspect of learning. Specifically, we explore differences in memory performance

between neurotypical individuals and individuals with epilepsy within a task

that involves the addition of objects from a scene.

We created a task where participants watched a series of similar short videos.

Later, videos were replayed with the addition of certain objects that appeared in

earlier videos. Data analysis in python was done to calculate the duration of time a

participant spent looking at these added objects. An initial test-run of this toolkit

with neurotypical individuals shows the possibility of using a toolkit such as this to

assess memory. Our hope is that this toolkit can inform technologies that lead to

better learning outcomes for individuals with epilepsy.
