Cancellation tests have been widely used in clinical practice and in research to evaluate visuospatial attention, visual scanning patterns, and neglect problems. The aim of the present work is to present a visualized interface for the visuospatial attentional assessment system that can be employed to monitor and analyze attention performance and the search strategies used during visuospatial processing of target cancellation. We introduce a pattern identification mechanism for visual search patterns and report our findings from examining the visual search performance and patterns. We also present a comparison of results across various cancellation tests and age groups. The present study demonstrates that our system can obtain more processing data about spatiotemporal features of visual search than can conventional tests.
取消测试已广泛应用于临床实践和研究中，以评估视觉空间注意力、视觉扫描模式和忽视问题。本研究的目的是为视觉空间注意力评估系统提供一个可视化界面，该界面可用于监测和分析注意力表现以及目标取消的视觉空间处理过程中使用的搜索策略。我们引入了一种用于视觉搜索模式的模式识别机制，并报告了我们在检查视觉搜索性能和模式方面的发现。我们还比较了各种取消测试和不同年龄组的结果。本研究表明，我们的系统比传统测试能够获得更多关于视觉搜索时空特征的处理数据。
