An inexpensive, microcomputer-based system was developed for recording movements in real time. The positions of 5 serially illuminated, infrared emitting diodes fixed on the object of interest were tracked by a remote, position-sensing photodiode. Positional information from the photodetector was digitized by an LSI 11/23+ microcomputer (sampling rate = 50/s/channel) and stored for subsequent analysis. Any microcomputer equipped to perform analog-digital conversion is compatible for use with this system. The small size of the components that are mounted on the animal allows movement to occur virtually unimpeded and makes this recording system especially suited for small animal observation.
开发了一种基于微型计算机的廉价系统，用于实时记录运动。通过一个远程位置感应光电二极管跟踪固定在感兴趣物体上的5个串联发光红外二极管的位置。来自光电探测器的位置信息由LSI 11/23+微型计算机数字化（采样率=50次/秒/通道）并存储以供后续分析。任何配备模拟数字转换功能的微型计算机都可与该系统兼容使用。安装在动物身上的部件体积小，几乎不妨碍动物运动，使得该记录系统特别适合用于小动物观察。
