Anthropomorphic External Human-Machine Interface Design of Autonomous Vehicles in Roblox to Change Road Users' Behavior

초록

Can autonomous vehicles (AVs) interact emotionally with other road users to influence their behavior? To address this question, we developed an AV with external human-machine interfaces (eHMIs) in Roblox. The anthropomorphic facial expressions of the AV which conveyed the emotional state of the AV were designed. We assumed that people would behave better with an anthropomorphic AV, resulting in better traffic flow. In this paper, the late-breaking results of our pilot A/B test conducted to select appropriate emojis are presented. The results show that participants felt positive about the anthropomorphic eHMI because of the intuitiveness of the emojis, which made them feel better and less stressed in traffic situations. © 2023 IEEE.
