虚实结合的可穿戴产品适合性检验研究

目的 为了更科学地研究和检验可穿戴产品的适合性,提出一种适合性检验方法,能够精确保留现实环境中的产品佩戴关系,并能将现实与虚拟的适合性检验研究相结合,得到合理的适合性检验结果.方法 以虚拟现实眼镜的适合性检验为例,通过高精度的三维测量技术将现实环境中的人、产品以及人—产品佩戴关系转化为三维虚拟信息,并以人—产品佩戴三维模型为参考基准对齐人和产品的虚拟模型,得到保留现实佩戴关系的人—产品佩戴模型组,再应用偏差分析法得出人—机佩戴区域的可视化适合性结果和统计数据,结合主观评价方法进一步分析产品的适合性.结论 虚实结合的产品适合性检验方法可在虚拟环境中高精度地保留现实环境中的人—产品佩戴关系,并能得到可视化的适合性检验结果,为检验和指导产品的适合性提供依据.

Fit Test Method Study of Wearable Products by Combining Virtuality and Reality

In order to study and test the fit of wearable products more scientifically, a fit test method need to be proposed, which can accurately retain the wearing relationship from real environment, and combine the fit test research both virtuality and reality to get reasonable fit test results. Then a fit test of thevirtual reality headset was taken as an example to illustrate the method. By using high-precision three-dimensional measurement technology, human, products and human- product wearing relationship from reality were transformed into 3D virtual information. By using the three-dimensional model of human-product wearing as a referencetoestablishthevirtual modelofhuman and products, the model group of human-product wearing which containing realwearing relationship was obtained. And visualized fit results and statistical data of human-productwearing area were obtained by deviation analysis method. Then combined with the subjective evaluation method,fit of the products was analyzedfurther. The fit test method of products by combining virtuality and reality can obtain the human-product wearing relationship from reality with high precision in virtual environment. And it can obtain the visual fit test results and provides basis for the test and guidance of product suitability.
