A humanistic-care factors application hierarchical design-model for intelligent elderly products

At present, many countries and regions around the world have entered an aging society, so the demand intelligent elderly product has begun to double. However, in the design process of intelligent elderly products, there is a lack of a set of perfect method model and evaluation criteria for the application of humanistic care factors in intelligent elderly products. To standardize the use of humanistic care factors in the design of intelligent elderly products. Firstly, this study uses grounded theory to code and analyze the humanistic care factors. Secondly, the analytic hierarchy process (AHP) and analytic network process (ANP) are used for comparative study to obtain the sensitivity priority of the application of humanistic care factors, and a new design method model is proposed. Finally, the fuzzy evaluation method is used to verify the rationality of the design method model. The study shows that the use of humanistic care factors has the greatest impact on emotion, especially in the consideration of Interactivity, followed by Color mildness and Companionship. The results are divided in the form of a hierarchical demand tower, to establish a new Humanistic-care Factors Application Hierarchical Design-model (HFAHD) for intelligent elderly products. The HFAHD can not only help designers to improve the design efficiency in the design of intelligent elderly products, but also further standardize the use of humanistic care factors in the design of intelligent elderly products. Through the combination of quantitative research and qualitative research, it is proposed to divide the use of humanistic care factors into hierarchical models to help designers better use the HFAHD. This study not only improves the design standards of intelligent elderly products, but also extends to other design fields in further research, and promotes the more rational use of humanistic care factors in design.
