Deiml-Seibt, Tina, Pschetz, Larissa and Mller, Boris (2009): A conversational model to display user activity. In: Proceedings of the HCI09 Conference on People and Computers XXIII 2009. pp. 318-323. http://doi.acm.org/10.1145/1671011.1671051

The creation of mechanisms to motivate user participation became a necessary strategy for evolution and sustainability of many online systems. Nowadays, most of these mechanisms are based on a form of displaying user activity, e.g. through badges or ranking scores. In this paper we discuss the current use of activity displays as incentives for user participation, and present IntroText, an alternative conversational approach. Based on the metaphor of introducing someone, IntroText sketches a behavioral portrait of users in an individual and non-competitive way. We describe the implementation of this feature pointing out to its potential to influence online behavior.

Pschetz, Larissa (2008): (hi}stories: supporting user generated history. In: Proceedings of ACM CHI 2008 Conference on Human Factors in Computing Systems April 5-10, 2008. pp. 3693-3698. http://doi.acm.org/10.1145/1358628.1358915

With more and more digital information being produced by individuals every day, we will soon be able to use it to understand the past. Based on this premise this paper presents {Hi}Stories, a system to support the creation and access of user generated contents as historical evidences. In {Hi}Stories users aggregate contents from Internet and are invited to contribute their own material. It combines a number of research themes: collaborative information structuring, combination of contents from online services, and visualization and browsing of structured information collections.
