There is a scientific article published last year entitled “Evaluation of the Tobii EyeX Eye tracking controller and Matlab toolkit for research” (DOI: 10.3758/s13428-016-0762-9), which details technical specifications of Tobii Eye X for research.
My question is: Is there any incompatibility if Tobii Eye X device is used for biomedical research BUT NOT USING Tobii EyeX SDK?
Apologies for the delay in response. Please bear in mind that using the EyeX for research that requires the storage of the gaze data is in fact strictly prohibited by the Tobii EyeX SDK licence agreement. The same is true for the Gaze SDK (which is now discontinued).
We do have another low level SDK available for you to try out @
