Linking Data from Eye-Tracking and Serious Games to NDD Characteristics: A Bibliometric Study

Computer-based applications incorporating eye-tracking technologies (ETs) and serious games (SGs) promise support for managing health problems. ETs can help to understand better how the eyes function, and SGs can contribute to higher user experiences and increased engagement. Collecting and aligning data on eye functions and games can provide evidence for professionals to diagnose or plan rehabilitation. However, it is difficult to understand how data from ET and SG and information on health problems can be combined to provide trustworthy evidence. Solutions that combine these technologies can provide more engaging training and reliable gaze-based measures for a variety of problems. This paper investigates this question for supporting children with neurodevelopmental disorder (NDD). Based on examining the scientific literature indexed in the Web of Science databases for visualizing bibliometric indicators from 2008 to 2023, it identifies promising studies examining research utilizing ET and SG technologies for NDD diagnoses or support. The results highlight an increased interest and publication trends. However, there is no go-to journal for the topic, and reporting of ET aspects varies greatly. There is a distinct lack of reporting on calibration methods and detailed descriptions of connections between major eye movements and specific psychology-based NDD measures.
