这项工作的主要目标是确定计算机鼠标是否可以作为一种低成本的设备，用于在心理物理学研究和生物医学应用的背景下采集二维人体运动速度信号。本文在综述相关文献的基础上，对鼠标运动获取的特征化问题进行了分析和讨论。然后，通过将鼠标数据与由视频运动跟踪系统和数字化输入板同时获取的信号进行比较，在水平振荡运动上测量用这种设备获取的速度信号的质量。在这项工作中收集的信息的合成表明，计算机鼠标可以用于可靠的采集生物信号的背景下，人体运动的研究，特别是对于许多应用程序处理的上肢末端执行器的速度。本文最后讨论了这种使用的可能性和局限性。
The main goal of this work is to determine whether a computer mouse can be used as a low-cost device for the acquisition of two-dimensional human movement velocity signals in the context of psychophysical studies and biomedical applications. A comprehensive overview of the related literature is presented, and the problem of characterizing mouse movement acquisition is analyzed and discussed. Then, the quality of velocity signals acquired with this kind of device is measured on horizontal oscillatory movements by comparing the mouse data to the signals acquired simultaneously by a video motion tracking system and a digitizing tablet. A synthesis of the information gathered in this work indicates that the computer mouse can be used for the reliable acquisition of biosignals in the context of human movement studies, particularly for many applications dealing with the velocity of the end effector of the upper limb. This paper concludes by discussing the possibilities and limitations of such use.
