InBCT 2.1 Information Management and Sharing Team Leader: Dr. Tuomas Lukka, Agora Center General Description We investigate hyperstructure and flexible user interfaces together as a solution to the information flood. A free software framework to base further research on gradually forms from our production quality subsystems. Goals - interactive hyperstructure: the user can connect any two items which will then be near each other in hyperspace, easily visible and accessible from one to the other. - novel interfaces taking advantage of modern graphics capabilities as well as new types of controllers, all built from commodity parts - ad hoc teamwork: non-centralized P2P version control of structured data. Two or more persons can form a small team to change an object and subsequently submit those changes for consideration by a larger group. The software will manage all versioning. Results Software: - Storm: distributed storage framework - fillets: a perceptually motivated improvement to graph drawing (see report) - identity visualization using procedural textures - irregular viewport edges distinguishable from document edges - prototype for browsing and collaborative annotation of PDF documents - Loom: Focus&Context RDF data browser Plan - individually usable, clearly separated subsystems - collaborative hyperstructure authoring in Loom - usability tests for several subtopics - unconventional controlling devices (e.g. game controllers) - true P2P networking using Storm Topic Map - object/document identity in user interfaces - P2P ad hoc networking for teamwork support - interactive creation of hyperstructure - bi-directional linking - Xanalogical hypertext - document management Research Reports Published: - Fillets: Cues for Connections in Focus+Context Views of Graph-like Diagrams - Freenet-like GUIDs for implementing xanalogical hypertext Submitted for peer review: - Buoys, break lines, and unique backgrounds: techniques for non-disruptive bidirectional spatial links - Storm: Supporting data mobility through location-independent identifiers - Bridging Javadoc and design documentation via UML diagram image maps In preparation: - procedural textures - explanation of the urn-5 namespace registered to our group - irregular edge shapes for visual clarity InBCT 2.1 Uudet tiedonhallintamenetelmät Tutkimme hyperrakenteen ja joustavien käyttöliittymien yhdistelmää ratkaisuksi informaatiotulvaan. Käyttövalmiista osajärjestelmistämme kasvaa tutkimusta tukeva vapaaohjelmistokehys. Tavoitteena on, että järjestelmässä erilaiset tiedot ovat yhdisteltävissä ja versionhallinta tukee tilapäistäkin ryhmätyöskentelyä. Vastuuhenkilö: FT Tuomas Lukka, Agora Center
