Abstract
For operational units in the security domain that work together in teams, it is important to quickly and adequately exchange context-related information to ensure well-working collaboration. Currently, most information exchange is based on oral communication. This paper reports on different scenarios from the security domain in which augmented reality (AR) techniques are used to support such information exchange. The scenarios have been designed with a User Centred Design approach, in order to make the scenarios as realistic as possible. To support these scenarios, an AR system has been developed and evaluated in two rounds. In the first round, the usability and feasibility of the AR support has been evaluated with experts from different operational units in the security domain. The second evaluation round then focussed on the effect of AR on collaboration and situational awareness within the expert teams. With regard to the usability and feasibility of AR, the evaluation shows that the scenarios are well defined and the AR system can successfully support information exchange in teams operating in the security domain. The second evaluation round showed that AR can especially improve the situational awareness of remote colleagues not physically present at a scene.
Highlights
Operational units in the security domain can be considered as action or performing teams (Sundstrom 1999). Sundstrom (1999) describes such teams of highly trained professionals as often facing complex and time-limited assignments with audiences, adversaries or challenging environments, all while being regularly confronted with unpredictable behaviour that requires a quick and effective response
We explore whether the visual information in augmented reality (AR) impacts the collaboration quality and individual situational awareness of team members in the security domain
This paper reports on the evaluation of an AR system that is being developed to promote information exchange as well as situational awareness for teams within the security domain
Summary
Operational units in the security domain can be considered as action or performing teams (Sundstrom 1999). Sundstrom (1999) describes such teams of highly trained professionals as often facing complex and time-limited assignments with audiences, adversaries or challenging environments, all while being regularly confronted with unpredictable behaviour that requires a quick and effective response. Operational units in the security domain can be considered as action or performing teams (Sundstrom 1999). Action teams can further be considered as extreme work teams that are highly interdependent, whose performance can save or cost lives (Jones and Hinds 2002). Action teams are dependent on external support from inside and outside their organization (Sundstrom 1999). For operational teams in the security domain, the external support needs to provide relevant and up-to-date information to facilitate and maintain situational awareness (Straus et al 2010). 4.14 I would like to use more AR supported scenarios for training purposes 4.13 I would like to experience more interaction with objects and other characters in the scenario.
