目的 提出一种基于认知特性的信息界面布局美度评价方法,提高信息界面布局的合理性及评估结果的客观性。方法 根据视觉信息加工过程和视觉注意原理构建信息界面“布局—认知”的映射关系,结合软件工程领域的质量评估模型的构建逻辑,推导度量指标并建立信息界面布局美度评估模型,利用层次分析法计算各度量指标的权重,构建信息界面美度的综合评价方法。结论 以某数控机床的刀具补偿操作界面为例,通过等级排序法验证了该方法能够准确、客观地反映信息界面布局的美度情况。该方法具有较高的通用性,为信息界面布局方案的选择提供了一套客观量化的决策依据,辅助设计师对界面布局的分析与微调,从而避免设计优化上的盲目修改和创新。

Evaluation of Information Interface Layout Beauty Based on Cognitive Characteristics

The work aims to propose an evaluation method for the beauty of the information interface layout based on the cognitive characteristics to improve the rationality of the information interface layout and the objectivity of the evaluation results. According to the process of visual information processing and the principle of visual attention, the "layout - cognition" mapping relation of information interface was constructed. Combined with the construction logic of quality evaluation model in software engineering field, the metrics were deduced and the beauty evaluation model of information interface layout was established. The weights of metrics were calculated by analytic hierarchy process (AHP), and the comprehensive evaluation method of information interface beauty was constructed. Taking the tool compensation interface of a CNC machine tool as an example, it is verified that the proposed method can accurately and objectively reflect the beauty of the information interface layout by the hierarchical sorting method. The proposed method has high universality, provides a set of objective and quantitative decision-making basis for the selection of information interface layout scheme, and assists designers in analyzing and fine-tuning the interface layout, thus avoiding blind modification and innovation in design optimization.
