This paper presents a new interaction metaphor we have termed "god-like interaction".

People working out in the field act as sensors and have a more local understanding of the situation but may not be aware of the bigger picture as it develops. Currently, communication between participants is typically achieved using basic verbal communication via radio. With a large number of people in the field, managing this communication is quite complex, and tools to make this more effective are always desired. With the availability of outdoor augmented reality (AR) systems and indoor tabletop projector display systems, how can we combine these technologies to improve collaboration between indoor and outdoor users? AR systems are mainly focussed on presenting information to a single user, and to be used as a tool for collaboration, appropriate interaction metaphors and user interfaces need to be developed.In this paper, we propose a new interaction metaphor god-like interaction that facilitates improved communication of situational and navigational information between indoor users equipped with tabletop displays, and outdoor users equipped with mobile AR systems. We have based our interactions on the capabilities of mythical god-like characters portrayed in popular culture such as the computer game Populous, where a god-like creature controls a miniature isometric view of the world, and the mini-series The Stand, in which the hand of god comes out of the sky to interact with the environment. With our new AR metaphor, indoor users work with a tabletop display that is a miniature virtual representation of the outdoor world with the same top-down perspective a god-like character would possess. Indoor users use their god-like powers to point to objects in the tabletop world, and place physical props on the table to create new life-sized objects to be experienced by AR users outdoors. Outdoor users see these changes in real-time and experience these interactions as though they are
