well i didnt find any solutions yet because i am working on other projects right now.. but!
i got such a reply :
Hello,
The X2-60 connect be connected this way. It only works when connected to the Processing unit via USB amnd the unit to the computer via LAN connection, using appropriate drivers and software.
What you try to acheive is not really related to eyetrcking analysis but more to interaction. The Analysis SDK is not the appropriate tool but more likely using the Gaze interaction SDK:
This SDK not being a Tobii Pro product I suggest you check the FAQs and the develloper community on the Tobii website:
