Real-time and high-intensity teamwork management is complex, as team leaders must ensure good results while also considering the well-being of team members. Given that stress and other factors directly impact team members’ output volume and error rate, these team leaders must be aware of and manage team stress levels in combination with allocating new work. This paper examines methods for visualizing each team member’s status in mixed reality, which, combined with a simulated stress model for virtual team members, allows the team leader to take into account team members’ individual statuses when choosing whom to allocate work. Using simulated Augmented Reality in Virtual Reality, a user study was conducted where participants acted as team leaders, putting simulated team members under stress by allocating several required work tasks while also being able to review the stress and status of each team member. The results showed that providing Augmented Reality feedback on team members’ internal status increases the team’s overall performance, as team leaders can better allocate new work to reduce team members’ stress-related errors while maximizing output. Participants preferred having a graph representation for stress levels despite performing better with a text representation.
