What does offline mean for smart glasses?
It can mean no internet, no phone, or no wireless connection. Those conditions are different. Glasses and a phone may communicate locally while the phone has no internet, allowing some functions but preventing a fresh remote request.
State which part of the system is missing
Label the condition before discussing the result. "Phone connected, internet unavailable" describes something you can reason about. "Offline" alone leaves out whether the application and its stored data are still accessible on the phone.
Compare opening a saved note with asking for a newly received message. The first can use available local content; the second may require a remote service. A successful saved-note demonstration does not settle the new-message case, even when both appear through the same interface.
