Hi Gal,
Did you have any success in getting it to work?
The fact that your first post shows an empty spaaaaaace where you’d expect to see the firmware version makes me think that there might be a problem with your setup.
If it’s still not working or showing the version, you could start by opening “regedit.exe” (Windows Registry editor) and looking for the key "HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Windows\CurrentVersion\OEMInformation". Under that key there should be a value called "EyeTrackerModel". Since you have a PCEye Go, that value should be set to "PCEye2".
Without this value, Gaze Interaction Settings won’t recognize your eye tracker model properly, and would most likely not be able to read your current firmware version or offer an upgraded version.
Another possibility is that for some reason Bonjour is not installed/running on your computer. It’s a tool for zero-configuration networking, which is used for certain parts of communicating with the eye tracker, like firmware tasks.
Both the registry key and the Bonjour service should have been installed by the software suite that came with your PCEye Go (Installation & Configuration Guide).
Best regards,
– Joel
