菲茨定律及其若干修正版極限不適用性分析

劉嘉奕

【摘? 要】菲茨定律及其修正版被越來越多的設計師所接受，目前已被廣泛應用于交互設計的各個領域。論文通過對菲茨定律及其若干較有代表性的修正版的極限分析，證明了這些定律在極限狀態——目標區域寬度趨近于無窮大時不適用，為提出在極限狀態與普通狀態都較為適用的新公式建立了目標，從而為在常見的目標區域尺寸范圍內與實驗數據更契合、能夠更好地指導計算機交互界面設計的公式的提出提供了有較大潛力的研究方向。

【Abstract】Fitts' Law and its modified versions are accepted by more and more designers. At present， they have been widely applied in various fields of interaction design. Through the limit analysis of Fitts' Law and several of its more representative modified versions， the paper proves that these laws are not applicable in the limit state， that is， when the width of the target area approaches infinity. The paper establishes a goal for proposing new formula that is more applicable for both limit state and normal state， and then provides a research direction with great potential for proposing the formula which is more consistent with the experimental data and can better guide the computer interaction interface design within the range of common target area size.
