자율주행차 내부 편의장치 이동 시스템 개발 및 물리적 움직임 기반알림 사용성 평가

초록

This study proposed and evaluated a movement system for autonomous vehicle interior devices featuring lateral movement, rotation, and detachment capabilities. As Level 4-5 autonomous vehicles transition to passenger-centered living spaces, this system integrates in-vehicle devices with a rail-based mechanism for flexible spatial reconfiguration. Two experiments with 24 participants evaluated system usability and alert effectiveness. Study 1 obtained a SUS score of 76.04 (acceptable), with rotation receiving the highest preference (75.0 %). On the other hand, study 2 compared physical motion versus color-based alerts through eye-tracking, revealing that motion alerts generated significantly more fixations (M = 4.17 vs. 3.15, p = .001), though objective effectiveness did not consistently align with subjective visibility, particularly in simp ler movement scenarios. Ultimately, the findings suggest alert modality should be context-dependent, balancing unconscious attention capture with conscious user perception.
