    Emotion GaRage Vol. II
    Nadri, C.; Li, J.; Bosch, E.; Oehl, M.; Alvarez, I.; Braun, M.; Jeon, Myounghoon (ACM, 2020-09-21)
    Driver performance and behavior can be partially predicated based on one's emotional state. Through ascertaining the emotional state of passengers and employing various mitigation strategies, empathic cars can show potential in improving user experience and driving performance. Challenges remain in the implementation of such strategies, as individual differences play a large role in mediating the effect of affective intervention. Therefore, we propose a workshop that aims to bring together researchers and practitioners interested in affective interfaces and in-vehicle technologies as a forum for the development of targeted emotion intervention methods. During the workshop, we will focus on a common set of use cases and generate approaches that can suit different user groups. By the end of this short workshop, researchers will determine ideal intervention methods for prospective user groups. This will be achieved through the method of insight combination to generate and discuss ideas.

    Investigating the effects of demographics and framing on the robot-theater program
    Nadri, C.; Dong, J.; Swaim, H.; Ko, S.; Sanghavi, H.; Jeon, Myounghoon (SAGE Publications, 2020-01-01)
    While STEAM (Science, Technology, Engineering, Arts and Mathematics) education programs have shown promise in increasing students’ interest in STEM and arts & design fields, the effects of demographic and other contextual factors have not been thoroughly investigated yet. While conducting robot-theater summer youth sessions with forty participants of the TechGirls international summer exchange program, we explored these factors. Participants in teams of four to six students created a script for a theater play that required the use of programmable robots. Results seem to suggest the influence of demographic factors such as nationality, as well as the effect of framing on participant attitudes towards robots and STEAM education. Subsequent validation of these effects in other studies is expected to contribute to refining the design of robot-theater and other STEAM education programs.

    Multimodal Takeover Request Displays for Semi-automated Vehicles: Focused on Spatiality and Lead Time
    Sanghavi, H.; Jeon, Myounghoon; Nadri, C.; Ko, S.; Sodnik, J.; Stojmenova, K. (Springer, 2021-01-01)
    To investigate the full potential of non-speech sounds, this study explored the effects of different multimodal takeover request displays in semi-automated vehicles. It used a mixed design - the visual and auditory notification lead time was within-subjects, whereas the auditory notification spatiality was between-subjects. The study was conducted in a motion-based driving simulator with 24 participants. All participants were engaged in four 9-min driving tasks in level-3 automated vehicle and simultaneously performed a non-driving related task (NDRT, online game). Each driving session contained three hazardous events with takeover request (in total 12 requests per user). The results showed that 3-s lead time evoked the fastest reaction time but caused high perceived workload and resulted in unsafe and non-comfortable maneuver. In terms of workload and maneuver, 7-s lead time showed better results than others. Auditory displays with directional information provided significantly better reaction times and reaction types. Subjective evaluation, on the other hand, did not show any significant differences between non-directional and directional displays. Additionally, the results showed that braking is a more common first reaction than steering, and that the NDRT did not influence the takeover request.
