  abstract = {In groupware or community based applications the user
 interface is usually static or tailored to the individual user’s
 needs. Newer developments try to adapt the user interface
 automatically in regard to user contexts. Even though these
 techniques are proven useful, there exists no contextadaptive
 system taking the current context of a group or
 community in regard. In this paper, we briefly discuss the
 problems of defining context and present our understanding
 of context as a subset of the current information state. We
 provide an exemplary scenario to present different
 approaches how to compute group contexts based on
 semantic models and user contexts, and the consequences
 for the adaptation goals - in the interface or through
 changes at system functionalities or tools. We additionally
 discuss the problems occurring at evaluating adaptations
 and the value of group context for collaborative work.},

As experimental conditions we consider the role of textual context and linguistic complexity classes. Still preliminary in nature, our data suggests that semantic complexity is much harder to deal with than syntactic one, and that full-scale textual context is negligible for annotation, with the exception of semantic high-complexity cases. We claim that such observational data might lay the foundation for empirically grounded annotation cost models and the design of cognitively adequate annotation user interfaces.},

  abstract = {This pilot study investigates an experimental methodology for gathering data to create correlations between experiential factors measured by a gameplay experience questionnaire and player quality measures, such as playing frequency, choice of game, and playing time. The characteristics of two distinct games were examined concerning the aspects of game experience, subjective game quality, and game usability. Interactions within the three aspects were identified. The results suggest that gameplay experience dimensions flow and immersion are similarly motivating in different game genres, which however might not be equally enjoyable. On the one hand, usability ratings may be positively influenced when a game provides immersion and flow or on the other hand, flow and immersion may be negatively influenced by poor usability ratings. These results emphasize the need for an approach to classify games based on correlation patterns involving game experience, quality, and usability.},

In diesem Artikel werden vier Use-Cases vorgestellt, mit denen derartige Ansätze auf ihre allgemeine Anwendbarkeit hin untersucht werden können. Ist es möglich, alle vier Szenarien mit dem Ansatz abzubilden bzw. umzusetzen, so kann der Anspruch auf allgemeine Anwendbarkeit aufrecht erhalten werden.}

Context views aim at identifying the most important elements within an application in a generic way by exploiting context information.}
