Despite the widespread application of Autonomous Vehicles (AV) to various services, there has been relatively little research carried out on pedestrian-AV interaction and trust within the context of service provided by AV. This study explores the communication design strategy promoting a pedestrian's trust and positive attitude to driverless services within the context of pedestrian-AV interaction using non-verbal social cues. An empirical study was conducted with an experimental VR environment to measure participants' intimacy, trust, and brand attitude toward AV. Further understanding of their social interaction experiences was explored through semi-structured interviews. As a result of the study, the interaction effect of social cues was found, and it was revealed that brand attitude was formed by the direct effects of intimacy and trust as well as the indirect effects of intimacy through trust's mediation. Furthermore, 'Conceptual Definition of Space' was identified to generate differences in the interplay among intimacy, trust, and brand attitude according to social cues. Quantitative and qualitative results were synthesized to discuss implications considering the service context. Practical implications were also addressed suggesting specific design strategies for utilizing the sociality of AV.
尽管自动驾驶汽车 (AV) 在各种服务中得到了广泛应用,但在 AV 提供服务的背景下,针对行人和 AV 之间的互动和信任问题的研究相对较少。本研究通过非语言的社会线索,探讨了在行人和 AV 互动的背景下促进行人对无人驾驶服务的信任和积极态度的沟通设计策略。通过实验性虚拟现实环境进行了一项实证研究,以衡量参与者对 AV 的亲密感、信任和品牌态度。通过半结构化访谈进一步探讨了他们的社会互动体验。研究结果发现了社会线索的交互效应,揭示了品牌态度是由亲密感和信任的直接效应以及亲密感通过信任的中介效应的间接效应形成的。此外,还确定了“空间的概念定义”,根据社会线索产生亲密感、信任和品牌态度之间相互作用的差异。综合了定量和定性结果,讨论了考虑服务背景的意义。还提出了一些实际意义,为利用 AV 的社交性提出了具体的设计策略。
