The Inquisit 5 Tobii Plugin allows you to record gaze-point data and program gaze-contingent tasks with Inquisit 5 and Tobii eye trackers. The plugin communicates directly with your Tobii eyetracker to receive real-time gaze data including gaze point and pupil size. These gaze data are logged to a local file on your computer where they can be loaded into analysis packages such as MatLab to create heat maps and gaze plots. Your scripts can now programmatically access gaze data for using in gaze-contingent branching and task flow using the new eyetracker element. The Inquisit 5 Tobii Plugin uses the Tobii Analytics SDK 3.0 - see Tobii's SDK page for a list of compatible eye tracker models.

Affordable solution for eye tracking research

The Inquisit 5 Tobii Plugin provides a powerful, cost-effective alternative to Tobii Studio for conducting psychological research with Tobii eye trackers. The plugin allows you to leverage Inquisit's broad and flexible capabilities for presenting stimuli or administering cognitive/neuropsychological tests. In addition, you can program your presentation scripts with gaze-contingent logic such as that used in research involving parafoveal stimulus presentation and reading window tasks. The plugin records gaze data to a tab-delimited text file that can be imported into analysis packages such as MatLab, SPSS, and Excel for posthoc analyses such as gaze plots and heat maps.

Single computer for stimulus presentation and gaze-point logging

The Inquisit 5 Tobii plugin enables you use a single computer for stimulus presentation and gaze point logging. You can also use Inquisit's built-in screen capture feature to save snapshot of composed visual scenes for use in heat maps and gaze plots.

Combine Inquisit's powerful presentation features with Tobii eye tracking capabilities

Leverage Inquisit's wide range of features in your eye tracking research. Inquisit supports a wide range of presentation paradigms, from simple image and video displays to complex reaction time tasks and decision making paradigms. Leverage any of the paradigms in our test library, or program your own. Runs on both Windows and Mac OS X.

Download and Install

The Inquisit 5 Tobii Plugin is built into Inquisit 5 Lab, so if you have downloaded and installed Inquisit 5 lab, there's is nothing further to do. To enable the plugin, you'll need a registration key for the plugin, which you obtain by purchasing a plugin license. (Note - this is a different registration key than the one used to register Inquisit 5 Lab.)

Documentation and samples

Please visit our Tobii test library page for sample scripts demonstrating gaze-contingent tasks using Tobii eye trackers.
