Exploring the Effects of Interior Design Elements on the Uncertainty of Passengers of Fully Automated Cars

Abstract: Humans are masters in predicting each other’s behaviour and acting relatively appropriately in ambiguous and uncertain situations. Although road accident statistics show a slight decrease in the number of road traffic deaths, these numbers are still very high. Fully automated cars are said to offer the potential to bring everyone everywhere, avoid accidents, and save parking spaces. This does not mean that the objective benefits of fully automated cars are also perceived this way by society. We may feel uncertain about the intentions, behaviour, and reliability of these fully automated cars. Our uncertainty influences our behaviour and interaction. Uncertainty can alter our mental state and, thus, our behaviour. Uncertainty further shapes perceptions of and interactions with fully automated cars. People mustn't feel uncertain about the capability of the fully automated car to prevent misuse. Interior design could play a role in mediating the uncertainty that passengers of fully automated cars perceive. A study was conducted to explore the effects of interior design elements on the uncertainty of passengers of fully automated vehicles. Results of the conducted study, with 113 participants, indicate that factors such as familiarity, trust, and perceived control are significant considerations when addressing perceived uncertainty through interior design. Furthermore, the introduction of unfamiliar design elements and perceived loss of control may lead to an increase in feelings of psychological uncertainty.
