对计算机屏幕光标轨迹的分析可以深入了解限制光标有效定位的因素，并有助于人机界面的设计。因此，在标准设置下，由微软电脑鼠标控制的光标位置每5毫秒采样一次，运动学分析解决了光标定位的起始、加速和最终制导阶段所花费的时间比例。12名参与者使用电脑鼠标将光标移动不同距离（7.5厘米，15厘米），从屏幕中下的位置移动到不同直径的目标（8毫米，16毫米），分别位于电脑屏幕的左边，中间或右边。光标轨迹是不规则的，参与者经常越过他们的目标，花费70%的运动时间在终端制导上。参与者似乎使用他们运动的初始部分来建立控制器和显示器之间的映射。干预措施应设法减少光标定位的末制导阶段。
An analysis of computer screen cursor trajectories can provide insights into the factors limiting efficient cursor positioning and can assist in the design of humancomputer interfaces. Cursor locations as controlled by a Microsoft computer mouse with standard settings were therefore sampled at 5ms intervals and kinematic analyses addressed the proportions of time spent in the initiation, accelerative and terminal guidance phases of cursor positioning. Twelve participants used a computer mouse to move a cursor over different distances (7.5cm, 15cm) from a home location in the lower centre of the screen to targets of different diameters (8mm, 16mm), situated to the left, middle or right of the computer screen. Cursor trajectories were irregular, and participants regularly overshot their targets, spending 70% of movement duration in terminal guidance. Participants appeared to use the initial part of their movement to establish mappings between controller and display. Interventions should seek to reduce the terminal guidance phase of cursor positioning.
