Virtual Fitness Coach App Interaction Design by Using Kano-AHP-QFD Model

Abstract

As people become increasingly health-conscious and their living standards improve, fitness has become an important part of daily life. However, due to limitations such as time, location, and cost, many people are unable to go to the gym for regular fitness training. Therefore, designing a virtual fitness coach mobile application that caters to the fitness community is of practical significance. The purpose of this study is to improve fitness effectiveness by determining and quantifying the demands and weights of fitness enthusiasts in the interaction of a virtual fitness coach mobile application, transforming them into design elements, and enhancing user experience and satisfaction through their appearance in the app. To this end, this study proposes a virtual fitness coach mobile application design method based on the Kano-AHP-QFD model. First, a questionnaire survey was used to obtain 20 requirements for virtual fitness coach mobile application design from the fitness community, and the Kano model was used to classify them according to attributes. Secondly, the Analytic Hierarchy Process (AHP) was used for weight analysis, revealing that user fitness instruction and user life guidance needs are the most critical design requirements for the mobile interaction design of virtual fitness coaches. Finally, Quality Function Deployment (QFD) was used to transform customer needs and expectations into product or service design characteristics, ensuring that these characteristics are met. This paper combines three classic quality management tools to design and study the mobile virtual fitness coach application, verifying the feasibility of this method in solving similar design problems. This method not only provides practical design for the fitness community but also provides reference for the design of other mobile applications.
