摘要：

Speed-accuracy tradeoff is a common phenomenon in many types of human motor tasks. In general, the more accurately the task is to be accomplished, the more time it takes, and vice versa. In particular, when users attempt to complete the task with a specified amount of time, the accuracy of the task can be considered as a dependent variable to measure user performance. In this paper we investigate speed-accuracy tradeoff in trajectory-based tasks with temporal constraint, through a controlled experiment that manipulates the movement time (MT) in addition to the tunnel amplitude (A) and width (W). A quantitative model is proposed and validated to predict the task accuracy in terms of lateral standard deviation (SD) of the trajectory.
