Reply To: Checking whether if the eye tracker is connected

Hi Benjamin,

It looks like a simple copy/paste error. If you want to listen for changes in the User Presence state, try to replace TX_STATEPATH_EYETRACKINGSTATE with TX_STATEPATH_USERPRESENCE in the txGetStateValueAsInteger function call (row 9 in the last code snippet).

Then you need to check if the result is TX_USERPRESENCE_PRESENT or TX_USERPRESENCE_NOTPRESENT.

Moreover, I don’t think the txCreateStateBag row is necessary.

Please let me know how it goes.
