Enhancing human-robot interaction in restaurants: The impact of anthropomorphic features on perceived attractiveness
研究了餐厅服务机器人的拟人化特征（人形外观、感知性别、语音音调）如何影响顾客对其吸引力的感知，发现低音调语音显著提升吸引力，而外观和性别影响不大。
This study explores the impact of anthropomorphic features, specifically humanlike appearance, perceived gender, and voice pitch, on the perceived attractiveness of service robots in restaurant environments. Using between-subjects experimental design, participants were exposed to representations of robot servers with varying levels of human likeness, gender, and voice pitch. Results indicate that voice pitch—specifically low-pitched voice—significantly influences attraction toward service robots, while humanlike appearance and gender of the robots have minimal impact. This study is among the first to examine communicative characteristics like voice pitch in hospitality contexts, integrating it with Interpersonal Attraction Theory to understand attractiveness as a multi-dimensional construct.
