论文摘要
Fitts的定律是一个线性方程，将运动时间与运动难度指数有关。 FITTS定律的最近发现适用于声带的自愿运动，提出了一个问题，即言语生产理论是否意味着Fitts的定律。本字母在FITTS定律与语音生产的任务动态模型之间建立了理论上的联系。我们得出了FITTS定律的变体，其中截距和斜率是任务动力学模型参数的函数，难度索引是乘积对数或Lambert W功能，而不是对数。
Fitts' law is a linear equation relating movement time to an index of movement difficulty. The recent finding that Fitts' law applies to voluntary movement of the vocal tract raises the question of whether the theory of speech production implies Fitts' law. The present letter establishes a theoretical connection between Fitts' law and the Task Dynamics model of speech production. We derive a variant of Fitts' law where the intercept and slope are functions of the parameters of the Task Dynamics model and the index of difficulty is a product logarithm, or Lambert W function, rather than a logarithm.
