After completing the first prototype of the Prospero system I interned with Joe McCarthy at Nokia Research Palo Alto. During this internship Max Harper, Jiang Bian, and I built the C4 (Context, Content, and Community Collage) which was deployed a Nokia Research for about 9 months. The C4 system detected nearby users by detecting nearby Bluetooth devices, and then displaying photos from a user specified information feed (i.e. RSS, Flickr, Picasa) on nearby public display, augmenting the physical work with social media.
The ProD framework builds upon the lessons learned from Prospero and C4 providing an opensource public display framework designed to simplify the task of building audience-aware public display applications. Prospero provides abstractions for both the social and technical concerns for public display development, including extendable user profiles, context, privacy, and governance. The ProD framework uses SSAPP to maintain awareness of users in it's environment.
This research has resulted in a paper about our experiences deploying C4 at Nokia research, which was nominated for best of CSCW 2008, and a paper on the ProD framework to be presented at UIST 2008. I continue to be interested in both the design and development of proactive displays, there are currently two displays running a rewritten version of the C4 application using the ProD framework.
This project has been funded by STIET, GROCS, and Nokia. And would not have been possible without the help from Joe McCarthy, Mark Ackerman, Mark W. Newman, Michael Butler, David Hutchful, Hung Troung, Mouly Kumaraswamy, Perry Wong, Max Harper, and Jiang Bian.
