Get Data from Tobi XR and Dev Tools

[Mattia]

Hi everyone. I’m workin on a project regarding the simulation of low vision disability in augmented reality. I’m working in Unity with HTC VIVE Pro Eye; I’m using Tobii XR Inizialize which support SRanipal SDK and Dev Tools; by modifiyng gaze visualizer I’m able to simulate visual disablities such as scotomas or glaucoma.
It is my necessity to extract data from Tobii Eye Tracker. In Unity I found in Tobii XR packages some useful script related to extracting data from eye tracker such as TobiiXR.GetEyeTrackingData and TobiiXR_TrackingSpace, but i don’t know where to put there in scene and how they work. I create a scene very similar to Dev Tools XR, so I have a Main Camera with Dev Tool as child, and Tobii XR Inizializer. In order to extract data from eye tracker, where I am supposed to put the scripts mention before?
I mean, using an examples Unity scene such as Dev Tools, where I am supposed to put the script mentioned above in on order to map every movememnt of Dev Tools from the start of the scene to the end?

Hi @mattbarb, thank you for reaching out. Please bear in mind that the storage of gaze data requires the purchase of a special licence do to so.

You can read more about this @ https://vr.tobii.com/sdk/licences/

All the data that can be extracted from the Core SDK can be found @ https://vr.tobii.com/sdk/develop/unity/documentation/api-reference/core/

You can place the scripts anywhere in the scene to get the data, and we provide examples of how to do this in the API page (https://vr.tobii.com/sdk/develop/unity/documentation/api-reference/core/).

We don’t have a recorder or similar to automatically store data in our SDK because Unity offers plenty of ways of doing this with minimal code required.
