Receiving Gaze Data while Calibrating .Net/C#

[Dmytro]

Hello,
I’m using Tobii 4c tracker. .Net SDK: Tobii.Research.x86 v1.7.0.1070
In my .Net/C# project I receive Gaze Data through IEyeTracker.GazeDataReceived event, and when I start calibration, device stops to send data through the event.
Is this expected, that device does not send data when it is in calibration state?
Thanks.

Hi @justdimus, the 4C will not work with the Tobii Pro SDK. you need to use the Tobii Stream Engine API which you can request a download link for via https://developer.tobii.com/software-downloads/

Hi,
Thank you for the answer!
But, somehow I do able to work with my device through this SDK, and can control it. The only one thing disturbing me is that device does not send Gaze Data while Calibrating. Does calibration temporarily stops the Gaze Data exchange?
Thanks in advance.

Hi! Yes, indeed during calibration, gaze data stream should not be available.
