Thank you very much for your reply,
We have installed Unity and copy game source to both machines (Development and target machines) and run the game in both build and Unity editor modes. We have found that:
Both machines:
– OS: Windows 10
– Unity: 2019.2.15f1
– Tobii eye tracker 4C works perfectly in Windows.
Development machine:
– Tobii eye tracker 4C works perfectly in Windows.
– The demo Unity eye tracking scenes works perfectly
– Unity variables:
+ TobiiGameIntegrationApi.IsTrackerConnected(): true
+ TobiiGameIntegrationApi.GetTrackerInfo().FirmwareVersion: 2.27.0-4014648
Target machine:
– Tobii eye tracker 4C works perfectly in Windows.
– The demo Unity eye tracking scenes says “No Gaze Detected”
– Unity variables:
+ Host.isConnected: false
+ TobiiGameIntegrationApi.IsTrackerConnected(): false
+ TobiiGameIntegrationApi.GetTrackerInfo().FirmwareVersion: 0
It seems that the tobii_gameintegration_x64.dll could not connect to Tobii firmware on the target machines. We have also test with some other machines (same configuration). This problem seems to happen randomly on these machines.
Please help, thank you very much.
