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

3
Document Triage

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

4
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)

8
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.

Recent Directions

• Music Summarization and Management
• Multi-Application User Interest Models
• Effect of Opinion Expressions on Social Network
  Dynamics
• User Interaction History Interpretation
• Assistive Video Surveillance Systems
