Delayed Co-Presence Systems

The Zhao family exists across three time zones: grandmother in Beijing, parents in Vancouver, adult daughter in London. They are rarely awake simultaneously for more than a few hours. Traditional communication—phone calls, video chats—requires someone to sacrifice sleep. So they've developed something different.

Their homes are connected through a presence network. When grandmother cooks breakfast in Beijing, the ambient sounds and smells are captured and released into the Vancouver kitchen when the parents wake up, six hours later. The daughter in London receives them eight hours after that, as she returns from work. They're not communicating in real-time, but they're sharing the same sensory experience of a meal, stretched across a day.

They've developed a shared vocabulary around this asynchronous intimacy. 'Morning grandmother' they call the presence that greets them upon waking. 'Evening parents' is what the daughter experiences as she winds down. They record messages not as discrete communications but as ambient layers—commentary on the day that plays softly in the background of each other's lives.

The system has also learned to identify significant moments worth preserving. Grandmother's laugh at a television program, the sound of rain on the London window, a fragment of the parents' conversation over coffee. These become a shared archive of family life happening simultaneously across the globe.
