# AR Presentation of Team Members' Performance and Inner Status to Their Leader: A Comparative Study
## 7 Discussion
### Study Outcomes  
Results showed that stress feedback significantly improves user performance, supporting **H1**. Stress feedback also resulted in changes in the participants' task assignment strategy. Participants mainly focused on the stress level of operators as it was their primary way to ensure better performance. When the participants did not have stress feedback, they had to conjecture the stress level of operators, using their judgment based on other indicators. With stress feedback, the participants found the process easier to manage the stress level of operators. Overall, most participants could monitor their operators' well-being, which led to better team performance in our system. Providing operators' status feedback to team leaders is more direct and efficient than having them assess how well their team is via performance measures. For future AR information displays to team leaders, the AR information should contain the stress level information of the team members who could potentially receive workload.  
Given that a stress indicator improves team performance, the question is which stress presentation provides the most improvement. The results showed that the textual presentation of stress gave a better score, but the participants preferred the graphical presentation, supporting **H2**. Based on user feedback, some of the AR information (the Success and Score components) presented to the team leader is more understandable with a textual presentation due to the presence of numbers and the accuracy they bring. Other AR information, such as stress, was easier to understand with a graphical presentation because it gives a better understanding of the evolution of the value and a global idea of the value. The _Textual Stress_ condition was the best performance without the downside of being longer than the _Graphical Stress_ condition. Indeed, the analysis of the participants' strategy explanations revealed that while participants did not focus on time, the graphical presentation of the stress component was easier and quicker for them to comprehend and complete their tasks. Thus, before assigning tasks, participants waited for the stress level of operators to become lower than with the textual presentation. Another factor is that the graph takes more time to read than the _Textual Stress_ panel and the other textual indicators. Our experiment did not put time pressure on participants to allow inexperienced people to take part in the study with only basic training for the task. To further study the effect of the presentation style and the presence of stress feedback on the trial duration, a future study would propose a similar task to people with a managing background.  
We recommend that collaborative setting designers provide both textual and graphical presentations of information to team leaders. Indeed, the textual information leads to better performance, being more precise and processed faster, and the graphical presentation of information is preferred and is enough to obtain a rough idea of the information at a glance. Pursuing research on sharing people's status should investigate hybrid presentations to take advantage of both textual precision and graphical abstraction.
