考虑视觉搜索特性的指挥控制系统KLSM

Considering visual search characteristics on command and control system KLSM

传统的击键水平模型(KLM)专注于键盘和鼠标的操作分析,适用于简单软件界面任务完成时间的快速定量评估,但将其迁移到包含复杂信息特征的指控系统软件界面评估时,却会产生较大误差。为此,基于KLM,结合用户视觉特性,面向指挥控制系统典型任务,提出基于用户视觉搜索处理时间的物理操作时间单元指标,并通过实验获取用户视觉搜索处理时间典型参数,建立更精确的指控系统任务操作分析模型—击键和视觉搜索模型(KLSM),即考虑视觉搜索特性因素的影响。选取5类典型指控任务,进行对比实验验证,KLSM对任务完成时间的预测评估更为准确。

The traditional keystroke level model(KLM)focuses on the operation analysis of the keyboard and mouse,which is well-suited for efficiently quantifying job completion time in straightforward software interfaces.However,a significant error occurs when the software interface of the command and control system is transferred to evaluate complicated information characteristics.This paper introduces a physical operation time unit index for the command and control system,based on the visual search processing time of users.The index is derived from experiments that determine the typical parameters of user visual search processing time.Additionally,a more precise task operation analysis model called keystroke level and visual search model(KLSM)is established,which takes into account the impact of visual search characteristic factors.The comparative test examines the accuracy of the KLSM model in forecasting and evaluating the task completion time by using 5 typical command and control tasks as examples.
