Custom calibration in Unity

[Yann]

Hello there,

I am currently developing a Unity application where I am using the Tobii eye tracking feature of the HTC Vive Pro Eye. Some of the users suffer from hemispatial neglect which can make the calibration stage impossible.

To improve on that, I would like to do a custom calibration where I could manually set the dot position. What are my possibilities to achieve this result ?

From what I could see online, the TobiiXR SDK doesn’t provide this option. However I came across this option with the TobiiPro SDK which seems to do exactly what I am looking for. Is it possible to use the TobiiPro SDK with the HTC Vive pro Eye and what are the limitations ?

Any help would be appreciated. Thanks.

Hi @aperox and thanks for your query. I am afraid that the Tobii Pro SKD is not supported with the HTC Vive Pro Eye however, custom calibration is indeed available via the
Tobii Ocumen offering which you can read more about @ https://vr.tobii.com/sdk/develop/tobii-ocumen/configuration/

Please do let us know if you have any further queries. Best Wishes.

Thank you for the answer that’s very useful to me. About Tobii Ocumen, on the XR SDK website only the Pico Neo 2 Eye is listed as supported device. Is it still possible to use Ocumen with HTC Vive Pro Eye ?

Is there any more detailed information to implement the same.

Hi @aperox, my apologies you are correct that Tobii Ocument currently only supports Pico Neo 2 Eye. Accordingly, you can try to speak to the Tobii Pro team who have a dedicated VR contact page to see if they would be willing to help you using the Pro SDK however this support will soon be discontinued.

Please reach out to them regarding this matter @ https://www.tobiipro.com/product-listing/vr-analytics/ I hope you can find a solution for your project.
