This example demonstrates:
  • How to use Invisible Boundary trigger to detect changes in participant's gaze
  • How to use Custom Class to create Interest Areas
Description:

This example comes from the Implementing the Invisible Boundary Crossing Paradigm in Experiment Builder and demonstrates how to use eye position data in real-time to detect when a participant's gaze crosses an invisible boundary in a reading task. Upon crossing the boundary, a component of the text will change to a different state (akin to its unaltered form in a reading experiment).
