Maps in video games have grown into complex interactive systems alongside video games themselves. What map systems have done and currently do have not been cataloged or evaluated. We trace the history of game map interfaces from their paper-based inspiration to their current smart phone-like appearance. Read-only map interfaces enable players to consume maps, which is sufficient for wayfinding. Game cartography interfaces enable players to persistently modify maps, expanding the range of activity to support planning and coordination. We employ thematic analysis on game cartography interfaces, contributing a near-exhaustive catalog of games featuring such interfaces, a set of properties to describe and design such interfaces, a collection of play activities that relate to cartography, and a framework to identify what properties promote the activities. We expect that designers will find the contributions enable them to promote desired play experiences through game map interface design. 

Wearable computers are poised to impact disaster response, so there is a need to determine the best interfaces to support situation awareness, decision support, and communication. We present a disaster response wearable design created for a mixed reality live-action role playing design competition, the Icehouse Challenge. The challenge, an independent event in which the authors were competitors, offers a simulation game environment in which teams compete to test wearable designs. In this game, players move through a simulated disaster space that requires team coordination and physical exertion to mitigate virtual hazards and stabilize virtual victims. Our design was grounded in disaster response and team coordination practice. We present our design process to develop wearable computer interfaces that integrate physiological and virtual environmental sensor data and display actionable information through a head-mounted display. We reflect on our observations from the live game, discuss challenges, opportunities, and design implications for future disaster response wearables to support collaboration.
