显微仪器产品美度指标构建及评价方法研究

Beauty indexes and evaluation method of microscopic instruments

显微仪器外观美感能体现其产品的高端品质,同时提升操作者使用体验的愉悦性。建立显微仪器产品美度指标及评价方法能够量化显微仪器的外观美感,便于客观的形式美与人主观的感受美达成一致,从而有效指导显微仪器产品的美学设计。首先针对显微仪器产品的特点,基于形式美法则,依据Ngo和Birkhoff美度计算模型构建了显微仪器产品美度评价的7个量化指标,即平衡度、对称度、比例度、节奏度、整体度、秩序度、色彩美度;然后分析了7个美度指标间的相关性,建立了计算产品美度模糊评价矩阵R;最后以四款激光扫描共聚焦生物显微镜为样本,采用美度评价指标与模糊综合评价方法对其外观美感进行了主客观综合评价,结果显示哈工大设计的样本4的模糊综合评价向量B 4=[0,0.3534,1.0425,0.8883,1.2562],表明其美度等级较高,具有更好的整体感与秩序性。

The aesthetic appearance of the microscopic instruments can reflect the advanced qualities,while improving the pleasure of the operation experience.The establishment of aesthetics indexes and evaluation method of microscopic instruments can quantify the beauty degree of instruments’appearance,and make the objective formal beauty correspond with the subjective feeling beauty,so as to effectively guide the aesthetic design of microscopic instruments.First,based on the features of microscopic instruments,the rules of beautiful form,and the beauty calculation model of Ngo and Birkhoff,seven quantitative indicators for the beauty evaluation of microscopic instruments were constructed such as Balance,Symmetry,Proportion,Rhythm,Unity,Order and Color.Then,the correlation among 7 beauty indexes was analyzed,and the fuzzy evaluation matrix R for calculating products’beauty was established.Finally,taking four types of laser scanning confocal biological microscopes as samples,the subjective and objective comprehensive evaluation was made by applying aesthetics indexes and the fuzzy comprehensive evaluation method.The results show that the fuzzy comprehensive evaluation vector of the sample 4 designed by Harbin Institute of Technology is B 4=[0,0.3534,1.0425,0.8883,1.2562],which indicates that its beauty grade is higher than others,and it has a better performance of unity and order.
