Tobii sells both 'consumer' (Tobii eye tracking) and 'research' eye trackers (Tobii pro).
In their help article "Can I use a Tobii Eye Tracker for research purposes?" they state:
If you want to develop software for analytical purposes, post-processing or aggregation of eye tracking data across multiple users using an eye tracker from Tobii Tech, please contact the SDK Licensing team since you will need to obtain a special license to do so.
On the Developer zone they state:
Tobii’s consumer eye trackers are primarily intended for personal interaction use and not for analytical purposes. Any application that stores or transfers eye tracking data must have a special license from Tobii.
They elaborate on this in "Analytical Use of Eye Tracking Data":
Tobii distinguishes applications in two categories: Interaction Use and Analytical Use. Depending on the intended use of your application, you may need to apply for a specific license.
Beyond real-time interaction, knowing where we focus our attention brings value to a range of applications within behavioral research, usability testing, streaming of gaze data and even health assessments. These applications would involve transferring, storing and analyzing/aggregating the eye tracking data which is defined by Tobii as Analytical Use. For any application that store or transfer eye tracking data you must obtain a special Analytical Use license from Tobii.
What they are much less clear on is:
- Why do they introduce this separate licensing model? Surely, it has to do with pricing and the availability of Tobii pro eye trackers, but this still sounds like a very odd, hard to enforce, business model.
- How do they intend to enforce this? Can they sell a product and simply ask of buyers not to use it for a certain purpose?
- How difficult is it to obtain a license? Does anyone have experience with this?
- What are the inherent limitations of the consumer level eye tracker compared to the professional eye trackers?
