자율주행 자동차 eHMI의 설계 공간에 대한 체계적 문헌 연구

초록

Objective: We aimed at a better understanding and analyzing the design space of external human-machine interfaces (eHMIs). Background: Autonomous vehicles are expected to become major components in future transportation system. The eHMIs can be widely utilized to interact with road users instead of drivers. Despite of their potential applicability, a holistic understanding of research method and design features for eHMIs remains limited. Method: We applied a systematic review method to achieve the research objective. A total of 26 articles were finally included for the review process. The selected articles were analyzed depending on the research questions we elicited. Results: As a result, we provided the results on design space including design variables and levels. Conclusion: According to our work, it reveals that different considerations should be integrated for developing and testing eHMIs. Application: Our work provides insights into the development and design of eHMIs, particularly for both practitioners and researchers to conceptualize, implement, and develop their own eHMIs.
