Jazz Companion

Jazz Companion measurement system is dedicated to human eye movement acqusition with high temporal and spatial resolution. The signals measured by Jazz Companion include: - eye movement (horizontal and vertical) - head rotation velocity (3 axes) - head tilt (3 axes) - operator's speech / background sound - external digital / analog synchronization signals - visual stimuli status via light-based screen sensor Information about eye movement is acquired by analyzing the infrared light reflected from eye surface (1k samples/s). The system is powered through USB data link. It features 5kV optical isolation from host computer system, as well as external synchronization sources.
