Combining eye tracking and motion capture

The use of eye tracking devices with motion capture allows you to combine eye and body movement data to help understand human interaction or improve athletic performance. Qualisys supports different eye trackers, both head mounted and desktop mounted. Eye trackers are either fully integrated with QTM partially integrated through the QTM real-time protocol or frame-synced with Qualisys camera system.

The eye tracker data is visualized as a gaze vector with a maneuverable vector trace. If used together with a Qualisys video camera, 3D overlay is also possible. Gaze vector data can be plotted and smoothed1 in QTM or exported as a TSV or MATLAB file for further data analysis.
