基于特征分析的机电产品交互界面评价模型

An Evaluation Model for the Interactive Interface of ElectroMechanical Products Based on Feature Analysis

将特征元素作为交互界面基础,提出了基于特征分析的机电产品交互界面设计评价模型.对机电产品交互界面进行特征元素分解,运用相似性实验提取典型特征属性,并以层级分析法建立属性特征的语义量化模型,使感性语义词汇以量化的数理形式表达出来.分别建立外观特征与操作行为的映射规则,属性特征与功能部件的映射规则.评价模型以两种映射关系确定整体交互界面的特征表达,以此为基础进行计算,最终得出属性特征、外观特征、操作行为的效用值,以及整体综合效用值4个评价参数.以龙门刨床为实例验证了评价模型的有效性,而且评价参数可以有针对性地评价交互界面各功能部件、操作步骤对属性特征的表达程度.

Based on the features of electro-mechanical products, an evaluation model was proposed for their interactive interface. The features were first decomposed and the typical ones were extracted using similarity experiments. A quantitative semantic model was then built with the hierarchical analysis method and perceptual semantic descriptions can be expressed with quantitative mathematical forms. After that, the mapping between appearance features and operation, and the mapping between property characteristics and functional components were established, respectively. The two mappings determined the expression of the interface features, and the computation over these mappings yields property features, appearance features, utility values of operation, and overall utility values. The evaluation model was proved by the planer machine. The evaluation parameters can help to evaluate the expressiveness degree of the property features by means of the function elements and operation steps.
