At the moment, the EyeX Engine and its SDK is only compatible with Tobii eye trackers that can present themselves as a Windows USB-HID, at the moment the following eye trackers:
– Tobii EyeX Controller
– Tobii REX
– Tobii X2-30 (not X2-60)
– Tobii PCEyeGo (with firmware 1.1.5 or later)
Technically, it is possible to support other eye tracker models as well. To be able to prioritize this feature request against other things, it would be good to know your use case. What do you want to use the EyeX SDK for in your project?
