How Shared Screen Affected Team Collaboration Task, A Case Study of Ergonomics Experiment on Team Situation Awareness

摘要

Team situation awareness (TSA) had significant influence on collaboration work. As the essential interface of human computer interaction (HCI), visual display terminal was helpful for task performance enhancement. This study developed ergonomics experiment to investigate the impact of shared screen through team work and decision-making task. Three-member team played different roles on experiment task, and caption of the team was required to complete extra task based on others' report. During the experiment, both behavior performance and physiological measurements were recorded was indices of team situation awareness. And each team member was demanded to complete subjective rating scales to evaluate TSA afterwards. The results analysis revealed strong correlation between team situation awareness and collaborate work, while insignificant effect of shared screen usage on individual task.
