The work aims to construct a multi-sensory interaction design framework from a design perspective, to deal with the sensory experience fragmentation and technological fragmentation issues in public restrooms under the backdrop of deep aging in smart cities, and promote the transformation of public restrooms from functional spaces to emotional spaces. By integrating literature analysis and comprehensive on-site research with Tianjin as a model, a visual-auditory-tactile collaborative optimization strategy was proposed, and intelligent technology was applied for design practice verification. The research revealed that public restrooms in Tianjin had core issues such as widespread distribution but significant imbalance, insufficient emotional care in barrier-free design, and the need for improvement in the intelligent level of sanitary facilities. In conclusion, as an emotional medium, multi-sensory interaction design significantly enhances the user experience of elderly users in the process of urban elderly-friendly renovation, providing an innovative path that integrates humanistic care for the design of elderly-friendly public restrooms in smart cities and contributing to the construction of inclusive cities.
