Abstract :
A Macintosh program that has been developed to perform data acquisition and analysis of eye movements and related signals during vestibular testing is discussed. The program is designed for studies of visual tracking and vestibulo-ocular reflex function. The software controls digitization of test data, with interactive calibration and calculation of eye and head velocities from sampled position data. A selection of digital filters and plot scale factors is provided. Saccades, blinks, and artifacts can be removed easily during the interactive data reduction process. Comparison of eye and head movements is performed using nonlinear least squares curve fitting of the reduced data
