Aiming at the realistic challenges of high frequency and high complexity of public security events, the interaction mode and functional attributes of intelligent emergency equipment in China and abroad are systematically combed. Combined with intelligent technologies such as digital twin technology, intelligent wearable technology and sensor technology, the work aims to construct a three-dimensional design framework from scene requirements to technical empowerment and then to experience optimization to improve the functional reliability and humanistic attributes of emergency products in the disaster environment. Through literature review and case analysis, the core principles of interaction design were summarized, and the research hotspots of multi-modal fusion interaction, digital twin technology and human-computer collaboration mechanism were revealed. The research shows that the intelligent emergency equipment is evolving from single physical control to natural interaction. Through multi-modal collaboration such as voice, touch, vision and brain-computer interface, it significantly improves operational reliability and rescue efficiency in complex scenes, provides theoretical support and technical path for industrial design to empower public safety governance, and helps realize a new intelligent emergency ecology of human-computer collaboration.
