Abstract: Based on the principle of barrier free design and combined with the characteristics of the elderly user group, this paper analyzes the physical, cognitive and emotional factors that affect the interaction of intelligent medical products for the elderly. In view of the interaction behavior, interaction interface and interaction situation of the elderly intelligent medical products, three barrier free interaction design strategies including inclusiveness, aging adaptability and emotional interaction are proposed respectively. Furthermore, the characteristics of the elderly group, the interaction needs and the correlation of the interactive interface are further integrated to construct the barrier free interactive design model of intelligent medical products for the elderly.
