Understanding Trust in Automated Vehicles

Abstract

Autonomous vehicles (AVs) are developed to increase safety, and bring environmental benefits. Nevertheless, there is growing skepticism in society regarding these technologies, a tendency that centres issues of trust in research and design of future AVs. In this paper, we raise the question of how trust has been understood and researched in relation to automation within the field of Human-Computer Interaction (HCI) thus far and what has been identified as key issues to deepen our understanding of personal trust in contemporary AVs. To answer this question, we systematically reviewed 232 HCI research articles on trust in automation and AVs to identify a) key aspects of contemporary trust research theories and methodologies, and b) what dimensions of trust are in need of further investigation in relation to UX perspectives on trust. Based on the review, we discuss methodological implications of focusing on the experience of trust in future research.
