| The work of CWI will focus on the presentation aspects of personalized, media-centric hypermedia interfaces. The Cuypers proof-of-concept prototype, constructed in the first phase of ToKeN2000, currently focuses on the adaptation of hypermedia presentations to various end user devices. For example, a desk top computer, a hand-held device or a mobile phone. This device-driven approach was developed to validate our constraint-driven approach to hypermedia presentation generation. In the following phase of ToKeN2000, the device-driven approach will be integrated with a more user-centric approach, based on explicit user profile information. In order to adapt hypermedia presentations to an individual user's task and preferences, adequate user models need to be developed. Research to address this issue will be carried out in cooperation with KI/RUG in the context of the Optima project. To be able to convey the results of a multimedia database query to a user effectively, the individual multimedia objects need to be related by placing them in the context of a unified hypermedia presentation. This process of enriching the database content requires a number of steps. First, research is needed into appropriate rhetorical and narrative structures to guide the overall flow of the presentation. Second, research is needed into the process of mapping the rhetorical and narrative structures onto hypermedia presentation patterns. This process is driven by high-level hypermedia design rules which also have to be developed. Finally, research is needed into the realization of these hypermedia patterns in terms of a concrete hypermedia presentation format driven by lower-level design rules and qualitative and quantitative presentation constraint processing. |
