This Learn article will show you how to configure your hardware and Tobii Pro Lab to record E-Prime using an External presenter project.
The External presenter project enables you to use Pro Lab to record E-Prime's experiment runs* and later use it to pre-process and analyze eye tracking data, allowing you to combine Pro Lab's analysis tools with the power of E-Prime's experiment design components.
*Unlike the E-Prime and Tobii Pro Studio integration, Tobii Pro Lab does not perform a screen capture the stimulus display but rather recreates the stimulus display based on the stimulus/event related information that is sent to it by E-Prime.
To be able to run E-Prime together with a Tobii Pro eye tracker and Pro Lab you need to use E-Prime 3.0 together with the E-Prime Extension for Tobii Pro 3.2. This extension adds two package calls and two devices to the standard E-Prime package call and Device selection:
To build the E-Prime experiment you will use a combination of these two types of packages. The TobiiEyeTracker routines will be used mainly to manage and perform the eye tracker calibration, whereas the TobiiProLab routines will be used to trigger the Pro Lab recording and send the relevant experimental design information.
|Implement your experimental design||E-Prime||TobiiProLab|
|Implement and run gaze contingency/interaction components**||E-Prime||TobiiEyeTracker|
|Implement and run the eye tracker calibration||E-Prime||TobiiEyeTracker|
|Run the stimulus presentation, trigger the Pro Lab recording, and send stimulus/event information||E-Prime||TobiiProLab, TobiiEyeTracker**|
|Record the eye tracking data and E-Prime stimulus/event information||Pro Lab|
|Data pre-processing and analysis||Pro Lab, Matlab, R|
This integration supports a single computer hardware configuration, where both E-Prime and Pro Lab are installed and running on the same machine.
In the next section, you will learn how to set up the hardware configuration and install the software. These instructions assume that you will use a single eye tracker connected to your test computer.
Before installing your software and configuring the eye tracker, please make sure that:
Once you have confirmed this information and downloaded the necessary applications. Start by setting up and configuring your hardware system.
Make sure you have downloaded and installed the latest Tobii Pro Eye Tracker Manager. You will use this application to configure and update your eye tracker firmware.
Before installing make sure your test computer is connected to the internet. You will need the connection to activate the Tobii Pro Lab license. If your lab setup requires that your data collection computer is disconnected from the internet, you can disconnect it once the activation is done.
Next, you will learn how to prepare Pro Lab to record the E-Prime stimulus presentation and associated information.
Once your Pro Lab project is ready, open your E-Prime eye tracking experiment and connect E-Prime to Pro Lab and your eye tracker:
