Abstract

Recently technological drive on autonomous vehicle is on the rush. Along with the trend, researches on driver's perspective are increasing. However, previous studies have limitations in terms of study period and rich experience. In this paper, we conducted an ethnographically inspired fieldwork to observe human-autonomous car interaction. We had six participants to ride a prototype autonomous car on the real road for six days. After, we generated trust, distrust factors according to Lee & See's categorization of trust dimension: process, performance, and purpose. We derived eight distrust factors that saliently influences passenger's experience in autonomous vehicle. Our research broadens trust model into autonomous driving context based on real road field study and contributes to automotive community with design guidelines to increase trust toward autonomous vehicle.

최근 자율주행 자동차에 대한 관심이 높아짐에 따라 자율주행 자동차 관련 기술 개발에 대한 활발한 연구가 진행되고 있다. 이에 따라 자율주행 환경에서의 운전자 관점에 대한 연구도 조금씩 늘어나고 있는 추세이다. 그러나 일부 연구들은 자율주행 자동차에 대한 낙관적인 입장만을 보이고 있다. 하지만, 선행 연구에서는 실제 자율주행 자동차를 태우지 않았다는 한계가 있다. 따라서, 본 연구에서는 자율주행 자동차를 기반으로 인간과 차량 간 상호작용을 알아보고자 에스노그라피 접근을 통한 질적 연구를 진행하였다. 그 결과, 자율주행 환경에서 운전자의 경험에 영향을 미치는 8개의 불신 요소를 도출하였다. 결과적으로 본 연구는 기존 신뢰 모형을 통해 자율주행 맥락에 적용하여 확장하였다는 점과 결과를 바탕으로 자율주행 환경에서 불신을 낮추고 신뢰를 높여줄 디자인 가이드를 제시했다는 점에서 이론적 및 실용적 의의가 있다.
