A Case Study of Multi-Display Transition Seams in the Mars Exploration Rover Missions Elaine M. Huang GVU Center, Georgia Institute of Technology 85 5 th St. NW Atlanta, GA 30313 +1 404 385 1102 elaine@cc.gatech.edu ABSTRACT In this position paper, we suggest that seams between devices in a multi-device ubiquitous computing environment can take on many forms, notably explicit UI interactions, physical interactions outside of user interfaces, and social coordination steps necessary to appropriate devices within the environment. We describe our research in the area of shared, flexibly appropriable large display groupware. Specifically, we consider the multi-display environment used by scientists for the Mars Exploration Rover (MER) missions, and our observations of how these three types of overhead play out as users transition between MERBoard displays and other devices and display technologies available in the environment. INTRODUCTION The primary focus of our research is to understand the value, use, and adoption of large display groupware applications (LDGAs) that are casually appropriable within a workgroup. In undertaking our investigations, it has become clear that the content that resides on these displays and the ways in which users interact with them are highly dependent on how users migrate their work to them from the computational equipment on which they are resident, such as laptops, PDAs, and desktop machines. The “spaces between devices” can be as tight and straightforward as the effort necessary to display the content of a laptop on a projector onto a screen in the environment, or as wide and loose as moving from a conversation around a webpage on a desktop PC to a freeform, open-ended collaboration on an electronic whiteboard. In the former case, there is a lossless, one-to-one mapping of content from one device to another, and a clear set of interactions that support this task. The latter is considerably more abstract in nature- the migration of a concept, possibly with no actual transfer of digital content. Support for this migration may be entirely social with no explicit technical connection between the devices. In addressing the question of whether and to what extent migrating between multiple displays and devices within an environment should be seamless, it makes sense to consider not only the technical interactions that these devices require for these migrations, but also the broader issue of what constitutes these seams from interactional, social, and cognitive perspectives. Within a work multi-device work environment, “seams” should be considered not only insofar as the physical steps in an interface that users must perform, but also in how the broader interactions fit with the social context of an environment and whether they make sense in light of existing tasks and work practices.
