Episode notes
Theory-Driven Design
- Theoretical models help analyze, characterize, and invent new devices like the mouse.
- Fitts's Law predicts movement time based on target size and distance, enabling optimization.
Spoon-Banging Experiment
- Stu Card and George Lechleider debated a parameter in a model for predicting user action times.
- They conducted an impromptu experiment, banging spoons in the National Academy of Sciences, to resolve the disagreement.
Time Scales of Human Action
- Human actions can be categorized into bands based on time scales (e.g., biological, cognitive, rational, social).
- Understanding these bands aids in theory development and interface design.
