is it possible to subscribe to session event(data changing) on Glass(UI) side? We need to apply the logics driven by the putting data to the session at the backend side.
For example, Glass captured the photo and put it to the session data. Backend analyses this photo and send back to Glass information about the asset on the photo through the session again. We need to catch the moment when data was added to the session at the backend.
Could you advise?
