E-Prime® Extensions for Tobii

Powerful experimental design

Overview

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 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. 

Simplified 2 in 1 solution

Tobii Pro Lab and E-Prime Extensions 3.2 together offer a simplified solution to combine Pro Lab and E-Prime from PST. The 2 in 1 solution enables researchers to process the raw gaze data in Pro Lab with dedicated gaze data analysis tools while using E-Prime's powerful design and stimulus presentation features for the creation of sophisticated eye tracking experiments (including gaze-contingency).

Among other things, E-Prime features programmable experiments, precise stimulus timing, and integration with various data sources, such as response boxes and EEG devices. E-Prime Extensions is intended for research use only.

Tobii E-Prime Extensions

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

Features
