Hi @johari, The Tobii X2-60 is part of the Tobii Pro Business department.
This forum is intended for support with the Tobii EyeX and C4 Eye Tracker and associated SDK’s.
Please get in touch with Tobii Pro Support department directly @ http://www.tobiipro.com/contact/contact-support/ for a swift
answer to your query.
That being said, by the looks of your calibration results (ie long straight lines) this indicates mostly likely an issue with screen setup, so I would advise rerunning the setup guide as when you first installed the tracker and also please ensure you are running the latest firmware available for your device. Best wishes.
