“…Advances in single display groupware (SDG) technology (Stewart et al, 1999), have enabled the development of collaborative search systems for the co-located environment. The advantages of such systems are that they improve the awareness of collaborating searchers by bringing them together in a face-to-face environment.…”

Traditionally information retrieval (IR) research has focussed on a single user interaction modality, where a user searches to satisfy an information need. Recent advances in both Web technologies, such as the sociable Web of Web 2.0, and computer hardware, such as tabletop interface devices, have enabled multiple users to collaborate on many computer-related tasks. Due to these advances there is an increasing need to support two or more users searching together at the same time, in order to satisfy a shared information need, which we refer to as Synchronous Collaborative Information Retrieval. Synchronous Collaborative Information Retrieval (SCIR) represents a significant paradigmatic shift from traditional IR systems. In order to support an effective SCIR search, new techniques are required to coordinate users’ activities. In this chapter we explore the effectiveness of a sharing of knowledge policy on a collaborating group. Sharing of knowledge refers to the process of passing relevance information across users, if one user finds items of relevance to the search task then the group should benefit in the form of improved ranked lists returned to each searcher.In order to evaluate the proposed techniques the authors simulate two users searching together through an incremental feedback system. The simulation assumes that users decide on an initial query with which to begin the collaborative search and proceed through the search by providing relevance judgments to the system and receiving a new ranked list. In order to populate these simulations we extract data from the interaction logs of various experimental IR systems from previous Text REtrieval Conference (TREC) workshops.

“…However with large shared displays it is difficult to have equal collaboration when only one of the users has the input device, or the software doesn't support parallel input. In recent years, Stewart et al coined the term Single Display Groupware (SDG) to describe groupware systems which support multiple input channels coupled to a single display [6]. They have found that SDG systems eliminate conflict among users for input devices, enable more work to be done in parallel by reducing turn-taking, and strengthen communication and collaboration.…”

Abstract. Collaborative Augmented Reality (AR) setups are becoming increasingly popular. We have developed a collaborative tabletop environment that is designed for brainstorming and discussion meetings. Using a digital pen, participants can annotate not only virtual paper, but also real printouts. By integrating both forms of physical and digital paper, we combine virtual and real 2d drawings, and digital data which are overlaid into a single information space. In this paper, we describe why we have integrated these devices together in a unique way and how they can be used efficiently during a design process.

“…Researchers in Computer Supported Cooperative Work (CSCW) are now paying considerable attention to the design of single display groupware (SDG) i.e., applications that support the work of co-located groups over a physically shared display [16]. Our own work in SDG began with an investigation of transparent menus as an interaction technique that would minimize how people working close together would interfere with each other [19].…”

Groupware: Design, Implementation, and Use

Abstract. Effective groupware toolkits not only make it possible for average programmers to develop groupware, but also enhance their creativity. By removing low-level implementation burdens and supplying appropriate building blocks, toolkits give people a 'language' to think about groupware, which in turn allows them to concentrate on creative designs. This is important, for it means that programmers can rapidly generate and test new ideas, replicate and refine ideas presented by others, and create demonstrations for others to try. To illustrate the link between groupware toolkits and creativity, I describe example toolkits we have built and how others have leveraged them in their own work.
