Automotive driver monitoring systems (DMS) are in-cabin safety technologies utilizing infrared cameras and computer vision to track eye gaze, head pose, and eyelid closure. Primarily used to detect fatigue and distraction, they trigger escalating alerts. Key market drivers include stringent global safety mandates, demand for ADAS, and fleet safety needs. Core strengths involve significant accident reduction and compliance with Euro NCAP. However, the sector faces major challenges like high system integration costs, false alert management, and in-cabin privacy concerns
