在人为因素和人体工程学研究中，眼球运动分析作为一种获取有关操作员认知策略的信息和推断个人认知状态的方法而受到欢迎。例如，最近的研究表明，眼睛注视点的分布对精神工作量的变化很敏感——工作量高时分散，工作量低时集中。空间统计算法可用于获取有关分布类型的信息，并可应用于在小时期内记录的注视，以评估个体所经历的心理负荷水平的在线变化。为了简化统计指数的计算并鼓励对视觉扫描的空间特性的研究，开发了一种用于检查注视的简单工具。该软件应用程序实现注视可视化、管理和分析功能，并包括用于根据原始注视点数据进行注视识别的工具。更新的信息可以在 www.astef.info 上在线获取，安装包可以免费下载。
In human factors and ergonomics research, the analysis of eye movements has gained popularity as a method for obtaining information concerning the operator's cognitive strategies and for drawing inferences about the cognitive state of an individual. For example, recent studies have shown that the distribution of eye fixations is sensitive to variations in mental workload-dispersed when workload is high, and clustered when workload is low. Spatial statistics algorithms can be used to obtain information about the type of distribution and can be applied over fixations recorded during small epochs of time to assess online changes in the level of mental load experienced by the individuals. In order to ease the computation of the statistical index and to encourage research on the spatial properties of visual scanning, A Simple Tool for Examining Fixations has been developed. The software application implements functions for fixation visualization, management, and analysis, and includes a tool for fixation identification from raw gaze point data. Updated information can be obtained online at www.astef.info, where the installation package is freely downloadable.
