System Design Of Human Factors Engineering Teaching Platform For Wearable Devices Based On Virtual Fit Experiments

With the rapid development of the current wearable device market,the needs for smart wearable devices are no longer limited to functionality,and comfortable wearing experience has also become an important factor in purchasing decisions.Therefore,more and more design teams focus on the fit design of wearable devices.In contrast to the design trends in the industry,design education in colleges and universities is still limited to purely stylistic design,and the concept of Human Factors Engineering is rarely implemented.Students lack access to data on product dimensions and ergonomic dimensions for their wearable device design practice,as well as quick fit testing aids.so it is difficult to obtain effective design guidance on Human Factors Engineering.Based on the above situation,a wearable device human factors teaching platform system based on virtual fit experiments is designed and developed to provide theoretical basis,design assistance and design verification solutions for wearable device design practice for students of industrial design,human factors engineering and related disciplines.The system is highly integrated with online courses on ergonomics and wearable device design,high-precision anthropometric data,algorithm fitting models,fit experiments and related algorithm research to assist student users with wearable device design and fit verification.In terms of algorithm research,the interference-gap algorithm traditionally used for reverse engineering is improved to make it more applicable to the wearable device fitness check.The results of the interference-gap calculation between the human fit model and the wearable device model are used to give relevant design evaluation and optimization suggestions to guide the design practice and design improvement work with a more scientific and theoretical approach.The innovation of this paper is to build a teaching platform system that integrates theoretical learning,design assistance and design verification around the human factors design of wearable devices,which provides scientific and accurate data support for student users’ wearable device design practice;at the same time,a virtual simulation experiment module is built based on the virtual fit experimental process of different wearable devices,which provides advanced and fast fit test for design and provides scientific guidance for size and form design improvement of wearable devices through calculation data.
