Fitts' Law
费茨定律，HCI 中的经典指向运动模型，预测用户移动到目标所需时间与目标距离和目标宽度之比的对数成正比。
English Definition
"A predictive model of human motor behavior stating that the time to move to a target area is a logarithmic function of the distance to the target divided by the target's width (index of difficulty)."
用法说明 · 针对中文母语者
中文译名常见「费茨定律」和「菲茨定律」两种拼法，源自 Paul Fitts。是评估指向交互性能的基准模型。
常见错误
- ·把 Fitts' Law 仅理解为「距离越远越慢」，忽略 width 对难度的影响
- ·拼写为 Fitt's Law 或 Fitts Law（正确为 Fitts' Law，带 s）
