Simulator for Individualized and Adaptive Driving (SIAD)

Outline:

Driving is an essential part of life for over 200 million people in the United States, where vehicle crashes are the number one killer of teenagers. While neurotypical drivers must be vigilant in an environment of distracted, aggressive, or inebriated motorists, drivers with neurodevelopmental disorders may present characteristics unconducive to optimally safe driving, exacerbating the challenge of driving. In the case of individuals with ASD, aspects such as atypical gaze processing and impaired motor coordination are likely to influence driving performance. However, it is only recently that researchers have begun to investigate driving performance in the ASD population. Given the risks of on-road driving assessment, driving simulators are a convenient alternative. Commercial driving simulation systems do not currently offer closed-loop adaptivity from modalities other than performance, such as eye gaze or physiology. To fill this gap, we developed SIAD – a virtual reality-based driving simulator that provides driving practice in a safe and encouraging environment with both real-time and offline feedback based on quantitative metrics.

SIAD presents various driving scenarios designed to challenge drivers on basic tasks, including turning, merging, and speed maintenance. Importantly, SIAD can be configured to adapt its internal parameters (e.g., difficulty) according to measured features of the driver’s physiological state or gaze patterns.
