Research On Product Design Of Multi Sensory Music Therapy For The Elderly With Alzheimer’s Disease

Alzheimer’s disease is a neurodegenerative disease,commonly known as Alzheimer’s disease.The elderly suffering from Alzheimer’s disease will have multiple cognitive,behavioral and emotional disorders.Due to the untimely discovery and intervention of the disease,the quality of life of the elderly will decline.According to statistics,there are about 10 million patients with Alzheimer’s disease in China,ranking the first in the world,and it is expected to exceed 40 million by 2050.The goal of this study is to improve the emotional,behavioral and cognitive abilities of patients by analyzing the characteristics of Alzheimer’s disease and designing.As a kind of non drug therapy that can effectively delay the development of Alzheimer’s disease,music therapy has some shortcomings,such as lack of multi sensory assisted music therapy experience,lack of classification verification of music from the perspective of professional utility,excessive dependence on music therapists,inconvenience to carry out in the family pension model,etc.From the perspective of experience level of music therapy,effectively improving music experience at all levels can maximize the effectiveness of music therapy.It is found that multi sensory design has a positive effect on the physiological,emotional,behavioral and cognitive levels of users,and the design principles of multi sensory products based on music therapy are proposed,which are consistency,music subjectivity,interaction,innovation and ease of use.This thesis innovatively puts forward a new idea that vibration tactile and vision should be involved in three levels of music therapy,namely,the premusical level,musical level and extra musical level.Through the design of tactile and visual sensory stimulation which are consistent with music characteristics,the experience of music activities can be improved,and then the effectiveness of music therapy can be improved.Through the analysis of sensory characteristics,the mapping design of music loudness/rhythm to vibration intensity/ rhythm is constructed,and verified by listening and tactile experiments,and effective conclusions such as the best vibration position,the best music type,the best finger movement are obtained.Because of the limitation of the combination of the two senses in improving the experience of the extra musical level,the music visualization design is carried out based on the conclusion of the auditory and tactile experiment,which is to establish the mapping design of the music loudness/ rhythm/ content to the static variables of the visual image/ the movement rhythm and the symbol semantics,and the mapping design between the behavior interaction and the change of the visual image.The positive effects of the three sensory forms on the emotion,behavior and cognition of patients were verified by the experiment of auditory,tactile and visual multi sensory music activities.Two groups of experiments provide the core function basis for product design.Based on the principles of multi sensory design,product design needs investigation and two groups of experimental conclusions,this thesis designs the domestic multi sensory music therapy products for the elderly with Alzheimer’s disease,and focuses on the function,modeling and CMF design of hand wearable products.In this thesis,through the combination of theoretical research and experimental design,vibration touch and vision are integrated into music therapy to help patients with different pension modes to carry out effective and interesting music activities conveniently by design.It provides a new idea of multi sensory design for exploring the combination of music therapy and personal products.At the same time,it has a certain guiding significance for the evaluation of product design for patients with Alzheimer’s disease.
