Hi @paulsheer, thanks for your query. I am afraid for the time being if you wish to use the Tobii Tech range of Eye Trackers under Linux then it will be necessary to use the Linux drivers as provided in the Tobii Pro SDK.
Whilst the Tobii Pro SDK is itself available free of charge and works without configuration on the Tobii Pro range of eye trackers, you will need to purchase a special licence to operate it in conjunction with a 4C or EyeX Tracker.
If this still appeals to you, then please send a speculative email to [email protected] and they should be able to provide you a quote.
