Presence beyond simple motion
Pair motion with occupancy timers, door sensors, and pressure mats to infer lingering versus passing through. A desk that migrates should carry its occupancy cue, perhaps via a small under-desk sensor on rechargeable power. Use aggregated signals to avoid false offs during quiet focus. When kids build forts, widen timeouts or use light-level thresholds to maintain comfort. Presence becomes a narrative, not a binary toggle, guiding graceful illumination shifts.
