Abstract: In order to improve the usability of multi-joint active and passive trainer, the usability evaluation index system of multi-joint active and passive trainer was constructed based on the user experience theory, and the usability evaluation model of multi-joint active and passive trainer was constructed through the fuzzy analytic hierarchy process (FAHP) and the membership quantitative processing method. Taking a multi-joint active and passive trainer produced by some company as an example, the evaluation index was determined by expert evaluation and the weight value of each index factor was calculated. Then the evaluation grade of each usability evaluation index was generated after the product was operated by the scoring team, and the final evaluation result was yielded based on the usability evaluation model of multi-joint active and passive trainer. The results show that the product usability can be evaluated comprehensively and accurately using the model, and then the usability problems can be identified and improvements can be proposed, thus informing the upgrading and innovation of products.
