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 that take 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

• Bridging Javadoc and design documentation via UML diagram image maps
• procedural textures
• explanation of the urn-5 namespace registered to our group
• irregular edge shapes for visual clarity

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.
