Participatory design process for an in-vehicle affect detection and regulation system for various drivers

Considerable research has shown that diverse affective (emotional) states influence cognitive processes and performance. To detect a driver's affective states and regulate them may help increase driving performance and safety. There are some populations who are more vulnerable to issues regarding driving, affect, and affect regulation (e.g., novice drivers, young drivers, older drivers, and drivers with TBI (Traumatic Brain Injury)). This paper describes initial findings from multiple participatory design processes, including interviews with 21 young drivers, and focus groups with a TBI driver and two driver rehab specialists. Depending on user groups, there are distinct issues and needs; therefore, differentiated approaches are needed to design an in-vehicle assistive technology system for a specific target user group.
