Waiting for Calibration

[William McCaffery]

Hi,

I’m using the CoreSDK with an EyeX and have been calibrating the tracker using

_host.Context.LaunchConfigurationTool(Tobii.Interaction.Framework.ConfigurationTool.Recalibrate, (data) => { });

I’ve been trying to trigger an event after calibration so the device can start streaming data after calibration is complete. Is there a way to recognise when the user has completed calibration?

Many thanks,

William

Hi @willmccaff and thanks for your query.
To recognise when calibration has completed you need to do set up a state observer listening for tracker status.
When tracker has left state ‘Configuring’ to state ‘Tracking’ you can create the actionable event.

Please find the snippet of code below to illustrate:

EngineStateProvider engineStateProvider = new EngineStateProvider(_host.Context);

EngineStateObserver<EyeTrackingDeviceStatus> _engineStateObserverTrackerState = engineStateProvider.CreateEyeTrackingDeviceStatusObserver();

_engineStateObserverTrackerState.Changed+= EngineStateObserverTrackerStateOnChanged;

...

private void EngineStateObserverTrackerStateOnChanged(object sender, EngineStateValue<EyeTrackingDeviceStatus> e)

        {

            // Based on tracker status do various actions…

        }

Hopefully, this is exactly what you are looking for! Please try this out and let us know how you get on. Best Wishes.
