It’s therefore diffi- cult to understand what constitutes a successful large- display groupware application and what affects their adoption. Although large-display groupware faces many of the same adoption and use challenges as convention- al desktop groupware, how people perceive and interact with large-display groupware yields some unique chal- lenges. We’ve built and evaluated several large-display groupware systems that address various workgroups, functions, and environments. This experience has given us broad expertise regarding the social dynamics and technical challenges surrounding large-display group- ware’s design. To enhance our understanding of these challenges, we’ve also undertaken a broad survey of exist- ing large-display groupware systems to understand how their purpose, design, and deployment affect the success of their integration into everyday tasks and practices. Large-display applications exist for many purpos- es from single-user desktop workspace (such as for magazine layout) to output-only information displays in highly public locations such as airports. Our study examines an emerging subclass of large-display appli- cations that seek to enhance workgroup interaction by supporting informal, nonurgent communication, col- laboration, and awareness. Unlike more formal large- display applications, such as meeting room or classroom systems, 1,2 the systems we consider here are designed for casual, ad hoc use and are persistently available to workgroup members. We’re especially interested in sys- tems that exploit the physical properties of large dis- plays, such as size and visibility, that make them appealing for multiuser interaction as well as for pas- sive or opportunistic information display. We therefore focus on the subset of large-display applications encom- passing groupware systems that use wall displays. Wall displays, including vertically oriented free-stand- ing, wall-mounted, and wall-projected configurations, foster a combination of interactive use and passive value. Unlike desktop displays, they offer content visibility from a distance and can therefore benefit users through ambi- ent or opportunistic information even when users aren’t directly in front of the display or actively interacting with it. The systems we examine in this article were deployed in a variety of office environments, targeting workgroup communication, information sharing, or work tasks....
