In a driving simulator study, we investigated two cooperation strategies, differing in terms of the user involvement. In the one strategy with low involvement the users were holding a button to continue driving, whereas in the strategy with high involvement, the user temporarily performs the entire driving task with steering wheel and pedals. Participants experienced these cooperation strategies in five ambiguous scenarios and rated them regarding safety aspects and dimensions of user perception. The strategy with high involvement is associated with more critical encounters including crashes. The strategy with low involvement is among others associated with higher ratings in perceived safety, perceived control and comfort, lower ratings on mental demand and is generally preferred by the participants.

Since motion sickness impedes user experience and the adoption of these technologies, accurate prediction is essential. This necessitates precise measurement of motion sickness variations across different environments to improve predictive model accuracy. However, current questionnaires lack detailed temporal and symptom-specific information, failing to provide accurate real-time data. To address this, we introduce the Real-Time Motion Sickness Scale (RMS), a practical tool designed for continuous monitoring of significant motion sickness symptoms. The RMS was developed by enhancing existing questionnaires through a systematic literature review and pilot tests. We validated its feasibility through a real-driving experiment with 24 passengers in an electric vehicle. The results demonstrated that the RMS accurately describes motion sickness severity and captures real-time changes in detail. Based on these findings, we discuss the applications of the RMS in motion sickness-provocative environments.</div></div>","PeriodicalId":55502,"journal":{"name":"Applied Ergonomics","volume":"128 ","pages":"Article 104507"},"PeriodicalIF":3.1,"publicationDate":"2025-05-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143948699","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
