Sharing Multimedia Content with Interactive Displays: A Case Study


The Plasma Posters are large screen, digital, interactive posterboards designed for informal content sharing within teams, groups, organizations and communities. Leveraging the fact that the physical world is often used as a canvas for asynchronous information exchange via paper fliers and posters, the Plasma Posters provide a platform for sharing interactive digital content in public places. People serendipitously encounter multimedia content usually only encountered from the desktop, while going about their daily business. In this paper we describe the Plasma Poster interface in detail, and offer and overview of the underlying information authoring, parsing, storage, distribution and publishing infrastructure, the Plasma Poster Network. We report qualitative and quantitative data collected over 14 months of use that demonstrate the Plasma Posters have become an integral part of information sharing within our organization. We conclude the paper by reflecting on the patterns of adoption, and speculate on factors that have contributed to the system’s success. Finally we briefly describe three other installations of the Plasma Poster Network and new interfaces that have been designed.
