摘要
为提高产品造型特征交互效果评价系统中手势识别技术的绩效可用性,文中设计一种基于VR技术的产品造型特征交互效果评价系统。设计系统分硬件和软件两部分。硬件部分选择虚拟现实头盔的型号并配套搭配PC机的硬件设施。软件部分构建软件整体框架,搭建产品外观模型,经过渲染和格式转换以提高兼容性;构建交互效果评价的隶属度函数,采用10种手势作为交互效果评价对象指标,建立手势识别绩效度量的模糊矩阵。实验结果表明,所提系统在绩效度量时间、错误次数、度量效率等方面的指标均优于原有系统,具有一定的实用性。
In order to improve the performance usability of the gesture recognition technology in the interaction effect evaluation system of product modeling features,a product modeling feature interaction effect evaluation system based on VR technology is designed in this paper.In the hardware part of the system,the model of virtual reality helmet is selected and matched with the hardware facilities of PC.In the software part of the system,the overall framework of the software is constructed,the product appearance model is built,and the compatibility is improved by means of rendering and format conversion;the membership function of interaction effect evaluation is constructed,and ten gestures are used as the index of interaction effect evaluation object,and the fuzzy matrix of gesture recognition performance measurement is established.The experimental results show that the designed system is better than the original system in performance measurement time,mistake number and measurement efficiency.Therefore,it has a certain practicability.
