Access pupil diameter

[Jeremy Gordon]

The specs indicate that the Vive Pro Eye collects pupil diameter for each eye, but I don’t see the related field in TobiiXR.GetEyeTrackingData result. Is this data programmatically available?

Hi @jrgordon, and thanks for your query. I am afraid that the Tobii XR SDK does not expose pupil diameter with this API.

To accomplish this, you would need to use the Tobii Pro SDK which you can download @ https://www.tobiipro.com/product-listing/tobii-pro-sdk/

Whilst pupil size is exposed in the .NET, Python Bindings, it may not be available in the Unity API, please check with Tobii Pro Support about this @ https://www.tobiipro.com/contact/support/

Please do let us know if we can provide any further information. Best Wishes.
