在本研究中，我们实证检验了两种类型的共享展示和不同的工作量水平对团队情境意识（SA）形成的影响。结果支持使用某些类型的共享显示器来提高团队绩效。人们使用共享显示的方式实际上相当复杂，并且与工作负载级别有关。研究发现，使用抽象的共享显示有利于提高团队绩效，而使用完全复制其他团队成员显示的共享显示则是有害的。在低工作负载级别下，没有发现与任何一种共享显示类型相关的性能增强或问题。在高负载和中等负载条件下，抽象共享显示的显著优势最为明显。团队互动风格的变化伴随着不同类型的共享展示的使用。本研究支持团队SA模型，并扩展了先前关于共享显示的研究。
In this study, we empirically tested the effects of two types of shared displays and varying workload levels on the formation of team situation awareness (SA). Results support the use of certain types of shared displays for enhancing team performance. The way in which people use shared displays is actually quite complex and related to the workload level. The use of an abstracted shared display was found to be beneficial for enhancing team performance/while the use of shared displays that completely duplicated the other team members displays were found to be detrimental. Under low workload levels, no performance enhancements or problems were found associated with either shared display type. In high and moderate workload conditions, the significant benefits of the abstracted shared display were most apparent. Changes in team interaction style were found to accompany the use of the different types of shared displays. This study supports a model of Team SA and expands on previous research on shared displays.
