polling 4C?

[cleo jones]

I am currently using eyeXHost.Streams.CreateGazePointDataStream(GazePointDataMode.LightlyFiltered) to respond to gaze; but the stream only updates on eye movement, and not when the gaze is paused or exits detection. Is there a way to detect the loss of gaze detection?

What I’d really like is, instead of attaching a callback to the gazepointdatastream, to be able to poll the 4C whenever necessary, and get: 1. is gaze tracked or not; and 2. if so, what are the coordinates?

Hi @cleojones, you can use the “userPresenceState” state found
within the Tobii Core SDK with sample code and detailed
instruction @ https://tobii.github.io/CoreSDK/articles/states.html

This should allow you to detect the presence of a user, and
act accordingly within your program.

For the capture of gaze co-ordinates, you can run the
sample program, “Interaction_Streams_101” available @
https://github.com/Tobii/CoreSDK
which shows how this is done.

Please let us know if we can be of further assistance.
