Three healthy individuals participated in a laboratory experiment that required routing a thin continuous thread through a series of pulleys mounted on a vertical work surface. Task precision demand was manipulated by altering pulley outer diameter (38 mm, 76 mm, and 152 mm) and groove width (3 mm, 6 mm, and 9 mm). The target location of each destination pulley relative to the origin at the mid-sagittal plane was also manipulated. These factors were hypothesized to influence hand motion trajectories, peak speed, and task completion time. Smaller pulley diameters and larger groove widths, representing lower precision demands, were associated with smoother trajectories and a faster task completion time. These preliminary findings suggest a systematic influence of task precision demands on movement kinematics and task performance.
三名健康个体参与了一项实验室实验，该实验要求将一根细的连续线穿过安装在垂直工作面上的一系列滑轮。通过改变滑轮外径（38毫米、76毫米和152毫米）和凹槽宽度（3毫米、6毫米和9毫米）来控制任务精度要求。每个目标滑轮相对于矢状面中点处原点的目标位置也进行了控制。这些因素被假设会影响手部运动轨迹、峰值速度和任务完成时间。较小的滑轮直径和较大的凹槽宽度代表较低的精度要求，与更平滑的轨迹和更快的任务完成时间相关。这些初步发现表明任务精度要求对运动运动学和任务表现有系统性影响。
