Tobii Pro Lab makes it simple for beginners to get started with screen-based eye tracking and offers a large degree of flexibility as you grow your research ambitions.
Tobii Pro Lab offers four project types tailor-made for your screen-based eye tracking experiments:
Screen – beginner-friendly experiment designs set up.
Advanced Screen – for advanced experimental designs.
External presenter – integration of third-party presentation software
Scene Camera – enables video feed from an external camera as a stimulus
Each project type has a specific set of modules providing various functions to ease your experiment flow. These modules include Design, Record, and Analyze.
The Screen project is for eye tracking studies on a computer screen. It has an intuitive interface and allows you to control the flow of your experiment with ease. You can group and randomize stimuli in various formats, such as videos, images, web pages, and text or record the whole screen. You can edit stimulus presentation settings like display position, background color, presentation time, and stimulus advancement methods. Available modules are Design, Record, and Analyze.
The Advanced Screen project type allows you to create screen-based eye tracking studies using more complex stimuli such as multiple images or image/audio combinations. Templates indicate where stimuli should appear and when audio should be played. The attributes of your stimuli, such as presentation location and time, are stored in a table, which is then imported to Tobii Pro Lab. This gives you much flexibility when designing your experiment and makes it easy to change trials. Available modules are Design, Record, and Analyze.
The External presenter project allows you to use third-party software and comes with the Record and Analyze modules. Use the External presenter project when using third-party software such as E-Prime to present stimuli and Tobii Pro Lab to analyze the eye tracking data. For a more consistent workflow, we recommend using the Advanced Screen Project in Tobii Pro Lab. Refer to the Tobii E-Prime web page or Tobii developer web page for additional information.
The Scene camera project enables you to use a video feed from an external camera as your stimulus. Thus, this project comes with the Record and Analyze modules. Use a Scene camera project when you use an external video camera to record events in the real world using a screen-based eye tracker.
Orduna-Hospital and colleagues (2023) combined Tobii Pro Fusion eye tracker and Tobii Pro Lab to assess eye movement conjugacy and gaze direction while performing the Hess Lancaster Screen Test and compared the results with the traditional subjective HLST performance. They used Tobii Pro Lab for the subject’s calibration, analysis of the recordings, and the segmentation of the selected time intervals into custom events.
Rodemer and colleagues (2023) measured cognitive load during static and dynamic instructional videos of complex chemical representations. The videos were presented in Tobii Pro Lab software while participants’ pupil diameters were recorded with Tobii Pro Spectrum. The researchers exported the raw pupilometry data with a custom-selected Tobii I-VT Fixation Filter for further statistical analysis.
Zhang and colleagues (2023) investigated whether mouse pointing is an efficient strategy for learning from labeled and unlabeled split-attention materials. The participant’s eye movements were recorded using Tobii Pro Fusion eye tracker, and Tobii Pro Lab was used for calibration, experimental design, recording, and analysis of the eye tracking data.
