  Emergency response events are fast-paced, noisy, and they require teamwork to
accomplish the mission. Furthermore, the increasing deployment of Unmanned
Aerial Vehicles (UAVs) alongside emergency responders, demands a new form of
partnership between humans and UAVs. Traditional radio-based information
exchange between humans during an emergency response suffers from a lack of
visualization and often results in miscommunication. This paper presents a
novel collaboration platform: RescueAR, which utilizes the paradigm of
Location-based Augmented Reality to geotag, share, and visualize information.
RescueAR aims to support the two-way communication between humans and UAVs,
facilitate collaboration across diverse responders, and visualize scene
information relevant to the rescue team's role. According to our feasibility
study, a user study, followed by a focus group session with police officers,
RescueAR can support rescue teams in developing the spatial cognition of the
scene, facilitate the exchange of geolocation information, and complement
existing communication tools during the UAV-supported emergency response.
