A Driver Monitoring System (DMS) is designed to monitor and evaluate driver states, including distraction, fatigue, and drowsiness. It issues warnings when necessary and can provide countermeasures to promote driving safety. Our study aimed to gauge the perceptions of Chinese drivers regarding DMS-induced privacy concern and their acceptance of this technology. We conducted a one-way between-subjects design to assess the impact of different DMS types—facial image-based, electroencephalogram (EEG) signals-based, electrocardiogram (ECG) signals-based, and vehicle motionbased—on privacy concern and acceptance via an online survey (N= 486). The findings showed that participants expressed moderate privacy concern but displayed a positive attitude towards DMS. They exhibited a preference for the vehicle motionbased DMS, which uses indirect methods for monitoring. Acceptance of DMS was higher among individuals who perceived the data as sensitive and lower among those with pronounced privacy concern. Our research may provide practical implications for the development of DMS.
