Extending research possibilities

Integrating E-Prime® with our eye trackers expands your research possibilities:

  • Train subjects to fixate and control eye movements
  • Give feedback on vigilance or attentive behaviors
  • Create interactive eye tracking paradigms
  • Create paradigms which change based on subject's eye gaze data, region of interest (ROI) hit tests, fixation, and user interaction

Comprehensive software package 

E-Prime® and E-Prime® Extensions can be purchased through our team. The E-Prime® Extensions software package includes:

  • E-Prime® Extensions
  • A library of sample paradigms for learning and paradigm adaptation
  • E-Prime® support and Tobii Pro hardware support

A starter program is offered by PST for E-Prime® Extensions customers. The goal of this program is to assist EET customers implement their first EET/E-Prime eye tracking experiment.
