On-line analysis of rapid motion with a microcomputer

A software package is described, which uses an Apple IIe computer with a digitizing board (Digisector 65) for analysing rapid motions of appendages of small insects from video images. Every 20 ms the program simultaneously analyses the position of two moving appendages after a background correction and the externally applied trigger stimulus. The data may be plotted in high-resolution plots with a matrix printer and evaluated with statistical methods.
