Human Factors of Computer Graphics Interaction

Techniques

The Research

The Goal of Interactive Graphics Systems

“We expect it to be benign and responsive in the same sense a trusted servant is expected to be”

The worker “wants the system to virtually disappear from his consciousness so that only his work and its ramifications have a claim on his energy”

The Problem

“For the system designer, the choices are bewildering How does one put together, from a multitude of techniques and devices, the combination best suited to meet the needs of a human being who must perform real work?”

Potential Sources of Guidance

Experienced-based guidance

Experiments with interaction techniques

Human factors literature, especially dealing with equipment design

“A SIGNIFICANT AND USEFUL BODY OF THE EXPERIENTIAL AND EXPERIMENTAL

CONCLUSIONS DRAWN FROM ALL THESE SOURCES”

The Solution

A Sample of the Catalog

Extra Details

Pull the most useful data from a variety of sources

Use consistent terminology

Simplify the options for the designer

Conclusions

Future Work

A model of user-computer interaction that can predict the performance of both new and skilled users of various interaction techniques.

Discussion Questions

1. Would you find this catalog useful when choosing interaction techniques today?

2. What interaction techniques do we use now that were not included in this catalog? Do these techniques fit into the authors’ organizational structure?

3. Are there other factors for evaluating the interaction techniques that the author did not include?

4. Can we achieve the authors’ goal of a predictive model of user-computer interaction? (or have we already)
