目的 研究听觉、触觉与视觉多感官刺激因素介入阿尔茨海默病老人护理的反馈效果，借助智能软硬件技术增强其对音乐的感知，设计多感官交互的老人智能穿戴产品。方法 根据感知替换及通感原理，创建能够将音乐转化为振动及视觉信息的感官替代方法，并通过实验测试分别验证听–触觉和听–触–视觉两类多感官交互原型的可行性。结果 在融合听–触觉的基础上加入视觉设计，可以更好地激发老人的言语行为能力。在收集被试者使用反馈分析结论的基础上设计了一款指尖振动音乐可穿戴设备——指尖钢琴，通过提供以触觉、听觉、视觉融合的多感官体验来促进患者的主动行为。结论 多感官交互产品的设计对改善阿尔茨海默病患者的情绪和主动行为具有一定的效果，对老年患者身体健康和生活质量的提高具有积极意义。

The work aims to investigate the involvement of auditory, tactile and visual multi-sensory stimuli in the care of the elderly with Alzheimer's disease, to enhance their perception of music with the help of smart hardware and software technologies, and to design a smart wearable product for the elderly with multi-sensory interaction. Based on the principles of perceptual substitution and empathy, a sensory substitution method was created to transform music into vibratory and visual information. And experimental tests were conducted to verify the feasibility of the auditory-tactile and the auditory-tactile-visual multi-sensory interaction prototypes. Adding visual design based on the integration of auditory-tactile senses can better stimulate the speech behavior ability of the elderly. A fingertip vibrating music wearable device, the Fingertip Piano, was designed based on the result of analysis on feedback from the subjects to promote active behavior by providing a multi-sensory experience that integrates touch, hearing and vision. The design of the multi-sensory interactive product is effective in improving the mood and active behavior of Alzheimer's patients and has positive implications for the physical health and living quality of elderly patients.
