Compare two eye trackers

Review the same text recorded with two trackers or setups.

These steps use the Full mode: switch to it in the top bar of the Scanpath view, or add ui=full to the app's address (Essentials and Full).

  1. Import each recording as a separate dataset, each with the Recording setup of its tracker.
  2. Open the first dataset in the Scanpath view and pick a trial.
  3. Turn on Compare. In scanpath B's row, choose the second dataset in Dataset B and a trial of the same text in Trial B.
  4. Compare fixation placement, spread and missing stretches. An overlay needs both datasets recorded on the same screen size. Otherwise the app shows the two scanpaths side by side.

This recording compares two participants in the bundled demo. For two trackers, choose the second recording in Dataset B.

Use the session-review steps to save observations.
