Fitts's Law
A predictive model stating that the time to reach a target depends on its distance and size — larger, closer targets are faster.
技術的詳細
Fitts's Law is a foundational concept in visual design theory. It influences how users perceive and interact with interfaces, affecting readability, hierarchy, and aesthetic appeal. The design principles behind fitts's law are codified in systems like Material Design 3, Apple's Human Interface Guidelines, and the W3C's Web Content Accessibility Guidelines. Implementing fitts's law correctly requires balancing aesthetic intent with accessibility requirements and cross-platform consistency.
