Welcome to this Tobii Pro Upgrade Key page. The information on this page will get you started using a Tobii consumer eye tracker with the Tobii Pro SDK.
The Pro Upgrade Key enables the Tobii consumer eye tracker to work with the Tobii Pro SDK. This capability is intended for users of consumer eye trackers who want to develop certain software applications. In order for developers to not be limited to gaze interaction, applications will need to be built on the Pro SDK, since this kit provides a license that supports this use case.
The Pro Upgrade Key holds information about the consumer eye tracker's serial number and will only unlock the eye tracker unit with that identifier. This is a text file that is signed and cannot be modified. It is not sensitive information, since it is useless with any other eye tracker than the specific unit identified in the text file.
The Pro SDK offers API support to apply the Pro Upgrade Key as part of the procedure to connect to the eye tracker. This key then opens up data streams for the specific eye tracker unit. Without the Pro Upgrade Key, there will be no data streams available from the consumer eye tracker via the Pro SDK (i.e. no gaze data can be accessed).
The following data is available when using the Pro Upgrade Key:
For more details, go to the Tobii Pro SDK documentation website.
To download the Pro SDK, go to the main Tobii Pro SDK product page.
The Pro SDK is compatible with all screen-based eye trackers from Tobii Pro by default. For these eye trackers, the Pro Upgrade Key is not necessary.
The overall design of the Pro SDK is intended for eye movement and gaze analysis use cases. It offers a thread-safe environment and other important functions for research and analysis. Therefore, the Pro SDK is the choice over any SDK that is meant for gaze interaction use. The Pro SDK is available in several platforms: Windows, Linux, Mac, as well as several programming language bindings, such as .NET, Python, and Matlab.
The technical description of how to apply the Pro Upgrade Key when using the SDK is outlined in the Tobii Pro SDK documentation.
In order to set up the consumer eye tracker (display area setting etc.), Tobii Eye Tracking Core Software is used. This software application is intended for gaming use. It is regularly updated and could also automatically alter the eye tracker's firmware. To avoid these firmware updates, do not update the Tobii Eye Tracking Core Software when new updates are available. Learn more here.
