Cognitive Science and Design
summary
Covers concrete cognitive findings and how they change UI choices: human vision favors edge detection and simple silhouettes (research suggests ~24 geons yield >306 billion combos), peripheral motion fires faster (roughly 190 ms central vs 80 ms peripheral in threat tests), color is a fast selector while shape requires linear scanning, and perceived progress can shift time judgments by ~10%. Shows implementations and tradeoffs in Google Now, Glass, Android icons, Gmail grouping and Docs walkthroughs, and reports a 34% increase in correct recycling when affordances match objects.
