Hi @nabru, I’m afraid as the older Gaze SDK is deprecated since almost 2 years now, we can not offer a great deal of support for developing using this API.
However, that being said, the older samples are still available online and you can have a look @ https://github.com/Tobii/interaction-samples
Within FormsSamples/UserPresenceForms/ we demonstrate how to detect the presence of a user.
To launch a quick calibration, you can run the following command:
c:\Program Files (x86)\Tobii\Tobii EyeX Config\Tobii.EyeX.Configuration.exe –quick-calibration
Please bear in mind however, that a full “proper” calibration is highly recommended for new users via the regular Tobii System Tray Icon Software.
