Enhancing User Experience in Autonomous Driving Levels 4 and Above: A Novel Seat Concept for Motion Sickness Mitigation.

The rapid advancement of technology, particularly in autonomous driving, has brought about a profound transformation in the automotive industry. This paper introduces a research-driven strategy aimed at tackling emerging challenges related to non-driving activities in autonomous vehicles, with a specific focus on mitigating motion sickness. Recognizing the growing prevalence of light usage in the cockpit and the expected rise in non-driving engagements, this study underscores the urgent necessity for innovative solutions. Through comprehensive research on future mobility trends, levels of driving automation, and user experiences, this paper proposes a novel automotive seat concept tailored to alleviate motion sickness arising from increased non-driving activities in autonomous vehicles. The proposed seat design features a wrap-around structure to facilitate enhanced privacy and flexibility in both personal and group activities. A key component of this solution is the Anti-motion Sickness Light Warning System, strategically integrated into the seat’s backrest. Leveraging ISELED technology, this system offers real-time synchronization with autonomous driving systems, issuing light warnings to passengers prior to unexpected movements, thereby minimizing the likelihood of motion sickness. While demonstrating promising outcomes, the paper acknowledges certain limitations. These include the necessity for further exploration of interactive elements within the seat design, research to exploit the potential of advanced lighting effects using ISELED technology and ergonomic considerations for the seat itself. By shedding light on the impact of autonomous driving on user experiences, this study contributes to the ongoing discourse and underscores the pivotal role of technology in shaping the future of automotive design.
