Hi @rvejendla, sorry to hear about your issues. Can you confirm that eye tracking is working as expected in the demo applications?

Please also specify for us if you are using the Native Pico SDK https://developer.pico-interactive.com/sdk
or the Tobii XR SDK https://vr.tobii.com/sdk/develop/unity/getting-started/pico-neo-2-eye/

If using the XR SDK, please specify exactly at which stage the process fails so we can identify the most likely source of the issues.

TobiiXR_EyeTrackingData eyes = TobiiXR.GetEyeTrackingData(TobiiXR_TrackingSpace.World);

Hi @rvejendla, glad to hear managed to get the issue resolved.

Just to clarify that for any others that may face a similar issue in getting the license to work, we would ask to double-check if the System Time on the Pico device is set up correctly (we’ve had customers having expired licenses because of this). Otherwise you would need to request a new license from Tobii.

Also, make sure to remove the TobiiOcumen license from the “License Asset” field in the TobiiXR Initializer.

Hi @rvejendla, sorry to hear that.. We will need some further information, although it could be that you have an old version of Ocumen.

Please specify for us:

– Do you have a valid Ocumen license that works? (Will be printed in the TobiiXR Initializer)
– Do you have any errors in the project?
– What Ocumen version are you using?

Hi @rvejendla, kindy confirm that you have a valid ocumen licence and importantly, exactly what version you are working with please, thanks.

Hiii
Unfortunately I was not able to use TobiiXR.Advanced.LatestData even after updating the license key and iam using Tobii Ocumen Latest Version 2021-03-18.
I see the below exceptions when I use the same.
1)Object reference not set to an instance of an object.when try to use TobiiXR.Advanced.LatestData
2)An attempt was made to access TobiiXR Advanced without having initialized it

provide any solution?

Hi @rvejendla, could you please specify how you are initializing the Tobii XR SDK?

If using the TobiiXR Initializer prefab, and if so with what settings and if you are somehow referencing it in code somewhere.

Are you able to get ET data from the regular SDK using TobiiXR.GetEyeTrackingData?

What Pico SDK are you using and lastly, what happens when you create a new project and only import the necessary SDKs and Ocumen and if it works there, following our getting started and installation guides:
