| * ++ Click to read description of work | A novel and systematic psychophysical experiment for human-multirobot interaction, involving simulated search mission, was designed to study the role of system and human factors on the collaborative task efficiency in an H-MRI search mission scenario within the context of cooperative perception. In this scenario, a human operator could control a team of robots performing cooperative perception in order to search for survivors in a disaster-like arena. While the system factors included the type of high-level control and the number of robots in the team, the human factors included skills and experience with video games, gender and age. Based on the results from 35 human participants, the first main finding of our study is that the collaborative task is performed much better in a scenario where the robots are fully autonomous in performing exploration of the world while the human operators are tasked only with searching for survivors in the explored regions of the world. When human operators are additionally tasked with controlling the robots, they perform significantly poorer unless they possess good video gaming experience. With such experience operators quickly adapt to the high-level control mechanism and apply good exploration strategies. Gaming experience could be interpreted as a proxy for operator training but the latter would need further experimental evaluation.++ | * ++ Click to read description of work | A novel and systematic psychophysical experiment for human-multirobot interaction, involving simulated search mission, was designed to study the role of system and human factors on the collaborative task efficiency in an H-MRI search mission scenario within the context of cooperative perception.

| - | * ++ Click to read about the results | Our second main finding is that there is only a slight benefit in increasing the number of robots in the team performing the collaborative task under the assumption that a single human operator is responsible for the actual survivor search and classification task. In fact, increasing the number of robots in a scenario where the robots together maintain certain optimal formations becomes detrimental to exploration as it rapidly increases the computational overhead. | + | * ++ Click to read about the result (1) | Our second main finding is that there is only a slight benefit in increasing the number of robots in the team performing the collaborative task under the assumption that a single human operator is responsible for the actual survivor search and classification task.

| - | * Based on these findings we could infer certain guidelines for developing an effective architecture for human-multirobot search missions. Clearly, cooperative perception speeds up the exploration process. However, to make the best use of the explored world regions, it might be beneficial to split a large number of robots into several small-size teams. A small set of such teams should be assigned to a separate human operator who in turn could be responsible for the search and classification task only in a specific region. Our future work includes developing such an architecture for search and rescue missions. We also intend to study how operator training could improve the collaborative task efficiency.++ | + | * ++ Click to read about the result (3) | Based on these findings we could infer certain guidelines for developing an effective architecture for human-multirobot search missions.
