Process and export Tobii gaze vector data

Reprocessing of gaze vector data

The Gaze vector data can be reprocessed in a file, both in reprocessing and batch processing. This is useful if you need to update the gaze vector data because of changed 6DOF data.

If you have changed the 6DOF data then you need to reprocess the Gaze vector data to update it. Follow these steps to reprocess it.

1. Click on Reprocess on the Capture menu.
2. Then select Calculate gaze vectordata in the Processing steps.
   • If you need to change the rigid body that is associated with the gaze vector, then go to the Gaze vector page and double click on the gaze vector in the list.
3. Click OK in the File reprocessing dialog.

Export formats for gaze vector and eye tracker data

The gaze vector and eye tracker data can then be exported and analyzed in external programs. You can either export it to TSV or MAT files.

• The Tobii eye tracker data is exported as analog data, see chapters Analog data (_a.tsv) and Analog/EMG for the format description. For more information about the Tobii eye tracker device data, see chapter Eye Tracker data.

• The processed gaze vectors are exported as gaze vector data, see chapters Gaze vector data (_g.tsv) and GazeVector for the format description.
