E-Prime® Extensions for Tobii Pro

Extending research possibilities

E-Prime 3 and E-Prime Extensions for Tobii Pro 3.2 can be used in two ways with our products.

In combination with:

• our screen-based Tobii Pro eye trackers for recording raw eye tracking data with E-Prime
• Tobii Pro Lab (version 1.111 or higher) which offers a simplified 2 in 1 solution for recording raw eye tracking data with Pro Lab and the possibility to replay and visualize gaze data, apply fixation filters and calculate meaningful AOI gaze data metrics.

Seamless E-Prime® integration

• Simplified setup: one-computer solution running both Pro Lab and E-Prime without timing constraints (two-computer solution optional)
• New External presenter project type in Pro Lab enables recording of the E-Prime stimulus presentation and eye tracking data
• Stimulus onset events and media files containing AOIs and associated tags are transferred from E-Prime to Pro Lab and automatically generated in Pro Lab
• Transfer of response and custom events that can be used for Times of Interest (TOI) creation

In Tobii Pro Lab:

• Replay stimulus presentation sessions with gaze data in Pro Lab
• Apply fixation filters to raw data
• Create visualizations of the recorded gaze data and calculate meaningful gaze data metrics in Pro Lab

In E-Prime Extensions 3.2:

• Complete of all communication with Pro Lab from E-Prime directly:
  • Perform calibration (regular, manual, infant)
  • Start and stop recording
  • Send media files with specified AOIs and Tags
  • Send stimulus and response events
  • Send custom events for Times of Interest (TOI) creation
• Auto-detect Tobii Pro eye tracker within E-Prime
• Give feedback based on gaze behaviors
• Create interactive and passive eye tracking paradigms with gaze-contingent functionalities
