Dr. Lori-Ann R. Sacrey, and colleagues compared visual attention patterns in toddlers diagnosed with ASD to their neurotypical (NT) peers using interactive games controlled with their eyes.
Attention has multiple aspects proven to be altered in ASD children compared to NT children. One of them is joint attention, or the ability of a child to coordinate their attention with another individual on the same object or event. Other aspects are the ability to sustain attention to the same stimuli, as well as the ability to disengage from it. Literature supports that ASD children show fewer episodes of joint attention, prolonged sustained attention, and delays in disengaging from a stimulus.
In this study, a group of ASD and NT toddlers was tested using computerized games designed to measure sustained attention, disengagement, and cognitive control in children. The novelty of these games is that they use eye tracking to control the games based on toddler’s eye movements, known as gaze contingency. This method allows the child to interact with stimuli that respond and adapt depending on where the child looks on the screen.
ASD toddlers showed reduced levels of initiating joint attention and longer sustained attention. However, both groups performed similarly on disengaging and cognitive control tasks. These results suggest that autistic toddlers have some attention strengths that could provide a foundation for building attention, communication, and academic skills.
Together, these results pave the path to continue exploring gaze contingency as an attention intervention methodology for enhancing attentional development in very young children with early features of ASD. Enhancing attention could have longstanding impacts on various domains, including language acquisition, initiating and maintaining social interactions, and learning in academic settings.

Biometric and Eye Tracking Specialist, Tobii
As an eye tracking and integration specialist, I get to learn about the needs of scientific researchers regarding eye tracking methodology and multimodal research. My motivation is to help scientific researchers who want to combine eye tracking with other electrophysiological sensors by enabling the best setup for their research.
Hamish Finlayson creates apps and games for kids with autism. Eye tracking is a valuable tool in the research and treatment of people with ASD.
In a research project aimed at developing an objective index to identify autism in patients, subjects were recorded with Tobii Pro eye trackers while viewing video clips. By analyzing gaze patterns, researchers developed a quantitative method to help diagnose autism.
In this brief talk Dr. Thompson shares videos and data of the exploratory and experimental investigations and discuss ways to improve the process in the future.
