To develop demonstration technology that can overlay hand videos on spatial images such as traffic
maps, and assess the impact of this technology on virtual collaboration. This work explores to what degree
gestures impact collaboration effectiveness in the task of traffic incident management, with the goal of informing
design of tools to support virtual collaboration in this domain. Methods: Eighteen participants worked in pairs to
solve three traffic incident scenarios using three different interaction approaches: 1) face-to-face: participants
worked together by marking up an electronic map projected on the table in front of them; 2) separated: participants
were separated by a soft wall while they worked together on the electronic map with electronic drawing tools; or 3)
hand images: same as 2 with the addition of the partner’s hand images projected on the map. Participants were
video recorded. The questionnaires were given to participants after each trial to evaluate workload, positive
interactions, team behaviors, connection to teammate, and frustration. Results: Participants spent more time on
the task and perceived a higher level of time pressure when using hand images than when working face-to-face.
When working face-to-face, participants felt more like their teammate was at the same table and felt less
disconnected from their teammate than when working separately or using hand images. Conclusions: The results
indicate that adding hand videos to a virtual drawing tool for the task of traffic incident management can increase
team behaviors and change the way in which team members communicate information.
