融合认知负荷的用户界面布局优化

为了优化项目管理系统界面, 提升界面的可用性, 提出一种融合认知负荷的界面布局优化设计方法. 该方法将客观认知规律与用户主观认知相结合, 形成布局设计原则, 并转化为可计算的界面布局多目标优化函数. 在此基础上, 利用麻雀搜索算法对目标函数编码, 寻求空间最优解, 得到布局优化方案. 为验证本文方法的有效性, 以某铁路项目管理平台首页为例, 使用该方法对其进行优化, 并将眼动生理测量方法引入评价过程中, 以测量眼动负荷大小为目标进行可用性测试. 实验结果表明优化后的界面布局相较于初始界面可用性指标有了明显提升, 证明了该方法的有效性且具有一定的实用性.

User Interface Layout Optimization Incorporating Cognitive Load

A design method integrating cognitive loads is proposed to optimize the interfaces of project management systems and improve the usability of the interfaces. This method combines objective cognition laws with subjective cognition of users to form layout design principles and then transform them into a calculable multi-objective optimization function for interface layout. On this basis, the sparrow search algorithm (SSA) encodes the objective function to seek the optimal solution in space and obtain the layout optimization plan. The homepage of a railway project management platform is taken as an example to verify the effectiveness of the method in this study. Specifically, apart from the optimization of the proposed method, the physiological measurement method of eye movement is introduced into the evaluation process, and the usability test is carried out to measure eye movement loads. The experimental results show that the optimized interface layout has been significantly improved regarding the interface usability index, which proves the effectiveness and practicability of the method.
