Hello. I’m developing application using Tobii Core SDK.
It was needed for me to create virtual window, and create interactors there. I have created this, using sample (Interaction_Interactors_102). But in my application activation focus does not works, and Activated event does not firing(but code is the same). It would be wonderful, if you will explain, what might be the reason.
Second question is how to assign activating using fixation to interactor. I did not found any example how to do this with the lastest SDK. I have tried to do this with AddBehavior() method when creating the VirtualInteractor, but had no success. (I’m afraid, that it was not works because of the same reasons, as in the first part of post).
And also, I’m interesting in how to use visual feedback (setting from the Windows Control) with fixation activation. Must it appears automatically, when it works, or I must make some configuration in the code?

Hi @oleksandrdubyna88, can you kindly clarify which API of the Core SDK you are using please?
Firstly, with regard to the Sample Application Interaction_Interactors_102 not detecting gaze properly,
a number of causes spring to mind. Are you sure to have Tobii.EyeX.exe running? Check process explorer to be sure. I assume the Tobii Tray icon is present and you can calibrate successfully? Are you sure to be running the latest
version of the both the Tobii Core software and SDK?
The sample application is very simple, so the issue most likely lies in the Core software not running.
In terms of adding a fixation for an interactor, you could use the FixationDataStream to detect the presence
of a fixation for each individual element within wpf:Behaviors.HasGaze routine.

I would first focus on getting the basic samples to run correctly first.. please go through the steps above and kindly
get back to me if you are still having troubles.
