title: Applicability of standard eye-tracking technique in people with intellectual disability: methodological conclusions from a series of studies.
abstract: Although considerable amount of evidence suggest that info-communication technologies have important potential to promote higher level of adaptive functioning and more efficient learning in people with intellectual disability (ID), very little is known about how people with ID scan visually the visual user interfaces of digital tools. Eye-tracking technique is widely used to study visual scanning processes and is used more and more extensively in assistive and educational technologies, too. Therefore, it is important to explore and understand the limitations and potentials of applying eye-tracking technique in people with ID. The present paper aims this by analyzing data from 4 studies (n=38/38 and n=15/30), via contrasting data from people with ID with data from neurotypical (NT) control subjects along 3 variables, indicative of the applicability of eye-tracking technique. Results strongly suggest that there are specific difficulties in using eye-tracking in people with ID, showing considerable individual variability but depending also on the nature of the actual task. Consequentially, using eye-tracking in this group expectedly requires special considerations and specific solutions.
