Information Visualization Using 3D Interactive Animation

1
Information Visualization Using 3D Interactive
Animation

• George G Robertson, Stuart K Card, and Jock D.
  MacKinlay
• Presented by
• David Wang

2
Goal and Motivation

• Seek successor to UI using Desktop metaphor
• Hardware prices dropping, performance rising
• What is there aside from WIMP

3
Strategies

• Making User workspace larger
• Enabling user interaction with multiple Agents
• Increasing real-time interaction rate between
  user and system
• Provide visual abstraction to speed information
  assimilation and retrieval

4
Identified Problems

• Multiple Agent Problem
• Animation Problem
• Interaction Problem
• Viewpoint Movement Problem
• Object Movement Problem
• Small Screen Space Problem

5
Workspace

• More screen space. Rooms. Multiple desktops.
• Denser screen space. Animation and 3D.

6
Agents

• Search Agents
• Clustering Agent
• Interactive Objects

7
Real-time Constraints

• Tune to Human Constants
• Cognitive Coprocessor Scheduler and Governor

8
Visual Abstractions

• Hierarchical Structure -gt Cone Tree
• Linear Structure -gt Perspective Wall
• Continuous Data -gt Data Sculpture
• Spatial Data -gt Office Floor plan

Strengths

• Formalizes and defines tasks that a
  next-generation 3D Animated UI would have to
  perform.

14
Weaknesses

• Sorry. The future didnt happen as envisioned.
  ?
• The desktop paradigm, augmented with the web
  paradigm survives. WIMP still rules. ?

15
Favorite Sentence

• In the 1990s, it is likely that information
  access will be a primary force in shaping the
  successor to the desktop metaphor.

16
Update to the UI Paradigm

• Web Book and Web Forager.
• Card, Robertson, York. 1996.
