Abstract: In order to comprehensively evaluate the smart bracelet for the elderly more thoroughly, an
evaluation model was established, so as to facilitate the evaluation and optimization of the final
scheme. The model was established from such 4 dimensions as product design, user experience,
human-computer interaction and practical production. Firstly, the fuzzy analytic hierarchy process
(FAHP) method was employed based on the triangular fuzzy number to acquire weight values of
every index. Then, the technique for order preference by similarity to ideal solution (TOPSIS) method
was utilized to evaluate and order every scheme. An example could be found in 16 schemes of the
smart bracelet for the elderly of a certain brand and prove the feasibility and practical significance of
this FAHP-TOPSIS method. Such an evaluation and optimization method can help solve problems in
consideration of the fuzzy thinking to systematize, hierarchize and quantify the thinking process. It
can thus ultimately propose a clear evaluation scheme and optimized method for the smart bracelet for the elderly.

Key words: suitable for the elderly, smart bracelet, fuzzy analytic hierarchy process and technique for
order preference by similarity to ideal solution, comprehensive evaluation, scheme optimization
