Hi @godel, I am afraid that the neither the EyeX SDK nor the Core SDK support profile handling via their respective API as this is handled by the EyeX Engine (Tobii Core Interaction Software)
To read further about how to create new profiles and modify existing ones, please review the link @ https://help.tobii.com/hc/en-us/articles/209530409-Create-a-new-user-profile
Apologies for the inconvenience. As a possible workaround, you can at the least view saved profiles in the registry @ HKLM\Software\WOW6432Node\Tobii\EyeXConfig\UserProfiles
You should not modify the contents, but as a quick means of viewing saved profiles perhaps this is sufficient for your needs?
