How can a smart-glasses app collect less information?
Send and retain only what the current task requires. A short display card often needs far less information than the full account record or service response from which it was produced.
Reduce the payload before it reaches the display
Our recommendation is to select the needed fields close to the data source. A task-status card might need a task name, state and next action. It usually does not need credentials, raw logs or unrelated messages. Smaller explicit payloads are also easier to inspect when something goes wrong.
For a meeting reminder, consider whether the wearer needs the title, start time and room, rather than every attendee's contact information. Write that decision into the message format. It is easier to maintain a deliberately small interface than to keep filtering accidental details from a large generic response.
