This paper presents a survey of research papers, within the research field of single display groupware, dealing with utilization of large screens for collaboration. The papers have been selected from three different digital libraries. An explorative study of these papers has been performed to decide upon a meaningful way of categorizing research within the field, and unite the lessons learned by previous contributors to the field. The contribution is an overview of the research field and in particular a resource for a practitioner within the field to consult when designing such systems. The overview is provided through a matrix classifying 30 papers dealing with an actual system in accordance with the input devices applied and the system level interface. In addition to this a listing of design challenges associated with employing large screens for collaboration is presented along with references to papers providing proposed solutions. We conclude that there is a tendency towards utilizing touch screens in pervasive systems and remote input devices in ubiquitous systems while there is a lack of research regarding the combination of remote and direct input devices for ubiquitous systems. Furthermore we conclude that the main design challenges researchers report relates to issues of concurrent interaction with the system. 1.
