Overview
How might we design multi-user awareness so people can trust and act on AI output?
When to use
- Essential for family voice assistants, shared smart displays, and office ambient agents where identifying the current speaker and scoping to their permissions is required for accuracy and safety.
When to skip
- Single-user personal devices with one account.
- Identification confidence too low for secure scoping.
- Household profiles forbidden by product policy.
Rules
Reading one user calendar to another without identification.
Voice match with no fallback when unknown speaker.
Silent switch between profiles mid-session.
Kids mode with same purchase permissions as owner.
