Development of a Questionnaire to Understand Future Users’ Preferences About Human-Centric Autonomous Car Interior

Recent technological news and developments demonstrate that autonomous cars and their interior will have the potential to offer numerous advantages to passengers and, consequently, it will affect their daily routines. Therefore, it is crucial to monitor the opinion of the population on this issue. The main objective of this study was to construct a questionnaire to evaluate the preferences of Portuguese users about human-centric car interiors and apply a pilot test to understand possible corrections that should be considered. The questionnaire was constructed based on a literature review and applied to a sample of 12 volunteers. According to the pilot test results, three questions need some improvements, and the participants made several suggestions. Overall participants’ evaluations of the questionnaire showed that the duration, structure, clarity of the text and relevance of the questions are adequate. The revised questionnaire will be an essential tool to collect the preferences of possible users of autonomous cars.
