Tobii Pro SDK

Free software development kit for easy and efficient development of analytical applications to work with screen-based eye trackers from Tobii in research scenarios. Offers multiple-platform support and support for several programming languages.

Features

Comprehensive toolkit for the development of analytical applications

The Tobii Pro SDK is a comprehensive toolkit to help researchers and software partners easily build analytical applications for research use with screen-based eye trackers from Tobii. It is designed specifically for the development of applications to analyze gaze data.

This kit supports the entire product portfolio of screen-based eye trackers from Tobii Pro. See details on the supported eye trackers.

Download the Pro SDK free of charge.

The Pro SDK is free of charge and requires programming skills in order to properly use it. Support access is limited to troubleshooting problems on the hardware and reporting possible bugs. Consultancy services are available for purchase if assistance is needed for programming.

“The new Tobii Pro SDK is extremely well-thought out and a significant improvement on the previous Tobii Pro Analytics SDK. The command logic is clean and clearly explained, and data structures are easy to interpret and provide exactly the information needed.”

Dr Marcus R Watson, Department of Biology, York University

One SDK, many applications

The Pro SDK offers multi-platform support (Windows, Linux, and Mac) and API bindings for several programming languages (.NET, Python, Matlab, and C). This enables the development of many different kinds of analytical applications—from custom research paradigms for scientific research to commercial applications. Built on a solid foundation, the Pro SDK reuses functionality across the different platforms and bindings. 

See details on the supported platforms and languages.

Advanced gaze data for your research

The Pro SDK gives you access to advanced gaze data streams that are relevant to your research.

  • Gaze data is provided as raw data separately for left and right eyes and shows the gaze origin in space (3D eye coordinates), gaze point, and pupil diameter (GazeData)
  • External TTL event signals from the eye tracker's sync-in port enable the synchronization of eye tracking data with other biometric data streams (ExternalSignal, only available for Tobii Pro Spectrum and Tobii Pro TX300)
  • Eye images (only available for Pro Spectrum)
  • Eye tracker status and notifications

The Pro SDK is the ideal and only choice for researchers who want to develop analytical applications, i.e. applications that analyze behavior based on data from the eye tracker. Other Tobii SDKs do not include a license for analytical use. Please see the end-user license agreements of Tobii's SDKs for more details.

Precise timing control

The Pro SDK offers advanced timing support, giving researchers precise timing control.

  • All data streamed from the eye tracker and supplied by the Pro SDK are timestamped by both the eye tracker´s clock and the computer's clock
  • The Pro SDK automatically compensates for time differences in real time, providing millisecond synchronization accuracy
  • Researchers are able to do post adjustments using the TimeReference stream for extreme demands on synchronization accuracy

Designed for ease-of-use

The Pro SDK is designed to be easy to use for researchers and students without compromising the functionality needed by experienced developers.

  • API bindings are tailored for each language environment/framework in order to be intuitive for developers
  • The Pro SDK is thread-safe
  • Comprehensive documentation includes release notes, initial instructions, detailed descriptions of various concepts, and concise reference documentation for all supported languages

Open source research toolbox support

Support for the Pro SDK has been added in common frameworks, facilitating the development of eye tracking-based experiments in research applications.

  • Full integration with PyGaze (Python), enabling easier use of eye trackers from Tobii Pro
  • Comprehensive code example, guiding the use of the Pro SDK with Psychtoolbox (Matlab)

Efficiency with the Tobii Pro Eye Tracker Manager

The Pro SDK is complemented by the Pro Eye Tracker Manager, free software that helps you manage and set up your eye tracker.

The common parts of the workflow for an analytical eye tracking application are supported by this tool, which can be seamlessly integrated with analytical applications built on the Pro SDK using call-in functions. This includes configuring the display area, viewing the track status (a visualization of the head box), and conducting user calibration.

Depending on the eye tracker model, the Pro Eye Tracker Manager will also allow you to update the firmware and change the sampling frequency.

Migration from earlier SDK's

The Pro SDK replaces our previous Tobii Pro Analytics SDK.

For current users of the Pro Analytics SDK, see the Pro SDK documentation for migration notes.
