Does Twinmotion/Unreal scene support the eye tracking feature from the HTC VIVE Pro Eye?

I look forward to hearing back from one of the experts ASAP since this will helps me to make a decision on my research design.

Thank you

Hello ,

Thank you for posting in the community your question regarding the eye tracking feature. Are you referencing to the Precision eye tracking powered by Tobii?

Here is an overview on how VR works for Twinmotion as this might help answer your question. https://youtu.be/NvCjWUgqCXk

You can take your Twinmotion project into Unreal Engine or directly into Unreal Engine depending on your project then use the SDK from tobii.

If you have specific UE question you can ask them on their forum.

Hope this helps.

Hi Vincent,

Thank you for the quick response. Yes, the question references precision eye tracking in HTC Vive Pro EYE powered by Tobii. The data I am planning to collect is the pupillary response and the heatmap of people's attention when observe a VR environment. Specifically, I hope to know whether the eye-tracking function is working if I import a Revit or 3ds Max file in Twinmotion then letting people wear Vive Pro EYE to observe the virtual environment.

The youtube video you posted is not working. Thank you so much.

Best,

Stephen

Hello ,

Thank you for the follow-up and for the added details and explanation. I fixed the Youtube link to the webinar as well but that will only provide information on the VR features and how to use it in Twinmotion.

At this time this Eye tracking is not something that can be done in Twinmotion but seems like this could be achievable with Unreal Engine. Thus you could take the content from Revit or 3ds Max and use the Datasmith Exporter plugin to send your content to the software and setup the scene accordingly with the SDK from Tobii.

Note: The Tobii XR SDK for Unreal does not currently support the HTC VIVE Pro Eye.

Kind regards,

Thank you so much, Vincent. I will revise my study design based on this valuable information you provided.
