Hello, thank you for the work. I followed the exact steps for Unity, but the xml file is still empty. Do you have any idea what might be the reason?

Hi Mert, In most cases, you just need to restart the SRruntime software right before running Unity to get the data, and check if you have set the key to start/stop collecting eye tracking data. In addition, have you tried the python api to see if you can collect any data from the headset even without Unity?

Hello, thank you for your response. Yes, I restart SRuntime every time. I also set the keys, and still the xml file is empty.

I have some confusions:

there is an additional file TobiiProVR_readme.txt. I also tried to follow those steps to see if it runs. [SteamVR] and [UnityVR] are the packages that should be downloaded to Unity, right? I downloaded SteamVR, and I can see its content in assets. However, there is no UnityVR package.
In the file it's written that all cameras should be removed. But in the next step, we are setting the position of a camera. Where should we add the camera from?
Additionally, when I try to calibrate the eye tracker, Unity console gives me Calibration Failure.

Can you help me with these? Best,

The document says use one of these two packages. If you have SteamVR, just follow the steps in SteamVR.
The file says remove the default cameras in the Unity a conflict, and then Drag and drop the "SteamVR\Prefabs[CameraRig]" prefab into the scene (this one has a built-in main camera)
I couldn't figure out how to do eye calibration within Unity either, I choose to use the HTC VIVE Pro Eye menu to calibrate the eyes before running Unity, I have attached the link for you.

Hello, thank you for your article. But, Tobii Pro SDK In version 1.9 the VR support was deprecated.https://developer.tobiipro.com/unity/unity-getting-started.html So how do you guys work now.

We use the old version for our simulator. I attached a google drive link to it in the document. https://drive.google.com/file/d/19ZlllVUZl2mWyRrg6JSof5vrMZ5ZkCz5/view

The empty xml file may be caused because the Tobii Pro SDK In version 1.9 the VR support was deprecated.https://developer.tobiipro.com/unity/unity-getting-started.html

To solve this problem, I have uploaded a sample test scene in document. I also attach the link here. sample scene
