An On-Road Study in Mitigating Motion Sickness When Reading in Automated Driving

Abstract
This on-road study explores the effect of a visual (VPIS) and haptic peripheral information system (HPIS) on a user’s level of motion sickness when engaging in reading activity while being driven in a fully automated vehicle (AV). Both systems notify the user regarding the upcoming navigational information in the lateral direction, and HPIS also supports the user from being involuntarily moved by the lateral acceleration when cornering. It was hypothesized that both systems would reduce the experienced motion sickness compared to those without any intervention. Eighteen participants with severe motion sickness susceptibility were exposed to low-frequency lateral acceleration that induces a moderate-to-severe dose of motion sickness. The automated driving was simulated by an automated-like instrumented vehicle and performed with the Wizard-of-Oz approach. The participants were asked to perform reading while being exposed to three different conditions (control-, VPIS-, and HPIS-condition), each for about 15-minutes. Results from a self-rating questionnaire indicated statistically significant decreases in motion sickness found with the presence of HPIS but not with VPIS. Results showed HPIS produced the least experienced motion sickness while VPIS exacerbated the symptoms of motion sickness. Adaptation effects were also found due to the repetitive exposure to the same route of automated driving. Keywords: automated driving, peripheral information system, motion sickness.
