Visual Knowledge Builder Communicate relationships between documents using visual and spatial cues and evolving visual languages. Features Implicit structure recognition Navigable history Links between spatial hypertexts via http

Document Triage Too much information, not enough time Searching, reading, and organizing tools share and provide support based on inferred user interest.

Web-based Adaptive Spatial Hypertext Information needs to be adapted based on the use context Information systems can employ multiple models in order to adapt content and presentation. Conflict occurs as different models propose contradicting changes. Conflict management Conflict avoidance Conflict recognition Conflict resolution WARP Web-based spatial hypertext Multi-model adaptation Fuzzy-logic spatial parser

VITE : Manipulating Structured Information in a Visual Workspace Problem: computers use formally-represented information but people work better with natural representations Approach: 2-way mappings in a visual workspace Combines: (1) information visualization and (2) visual parsing Editable visualization and mapping Direct manipulation of content in the workspace

Distributed Collection Manager Identifying important changes within Web- based collections Examples: bookmark lists, Yahoo! categories, paths Cannot control what happens to materials Requires ongoing maintenance to counteract change Human effort is expensive (Yahoo! surfers)

Design Exploration (DE) Software design is enhanced by input from a wide variety of users. DE Tools allow end users to create annotated partial designs, and provide searching and browsing opportunities for software designers.

Hyper-Hitchcock (FX Palo Alto Laboratory) Hitchcock video editor Automatic segmentation Initial shot selection Authoring via keyframes Hypervideo Editing Workspace for arranging clips Sequence information recognized with simple spatial parser Links expressed explicitly

XLibris (FX Palo Alto Laboratory) People annotate documents as they read for many reasons. Annotations can be used to help people return to parts of documents that they find important.
