Effect of Speech Display on Team Mutual Awareness and Diagnosis Performance
In many complex industrial systems, a team works together on digital systems. Team members need to gather information efficiently to maintain mutual awareness and do well in dealing with what may happen in the system. This research studies the effect of speech display in mutual awareness tools on team mutual awareness, individual performance, mental workload and team performance in simulated emergent diagnosis tasks of nuclear power plants at different task complexity levels. An experiment was conducted with 48 subjects (24 teams). Every team completed two scenarios. The results showed that speech display improved team mutual awareness in the low-complexity scenario. However, the teams without speech display did better in analyzing the accident than the teams with speech display in the low-complexity scenario. Furthermore, the teams with speech display were under higher workload.
