Abstract: In urban search and rescue (USAR) situations resources are limited and workload is high. Robots that act as team players instead of tools could help in these situations. A Virtual Reality (VR) experiment was set up to test if team performance of a human-robot team increases when the robot act as such a team player. Three robot settings were tested ranging from the robot as a tool to the robot as a team player. Unexpectedly, team performance seemed to be the best for the tool condition. Two side-effects of increasing robot's teammembership could explain this result: Mental workload increased for the humans who had to work with the team-playing robot, whereas the tendency to share information was reduced between these humans. Future research should, thus, focus on team-memberships that improve communication and reduce cognitive workload.

Abstract: A convenient way to test Urban Search And Rescue (USAR) robots would be in virtual environments (VEs). Evaluations in VEs are generally accepted as alternative for real scenarios. There are obvious differences between operation in a real and virtual environment. Nonetheless, the current experiment showed no significant differences in situation awareness (SA) and performance during several elementary tasks (e.g. slalom) between a virtual world and a previous experiment in reality (Mioch, Smets, & Neerincx, 2012). Only small dependencies between the unit tasks were found. The effect of individual differences (like gender, km driven per year, and gaming experience), were significant for certain elementary tasks. Testing robots in virtual environments could still be useful even if differences between VE and reality exist, since comparisons of different conditions in VE seems to have the same results as the same comparison in the field (Bishop & Rohrmann, 2003; Van Diggelen, Looije, Mioch, Neerincx, & Smets, 2012).

Abstract: In the near future, first responders may become equipped with mobile devices providing navigation, decision and communication support. Because of the complex and chaotic circumstances in which these devices will be used, the devices should support the creation and maintenance of adequate situation awareness. Extensive testing of such devices for crisis management in real-life is expensive, complex, risky and only possible for specific settings. Therefore, we developed a synthetic task environment that is suited for developing and evaluating new concepts. In this paper, we present the results of the first experiment in this environment. Participants had to rescue victims in a synthetic world, and were supported by a map of the area showing the location and orientation of the participant and the victims. The experiment focused on the effects of map size and user's spatial ability on the quality of the situational awareness that was developed by the first responders. Besides the results of the experiment, experiences with the use of a synthetic environment for evaluation and development purposes are presented.
