SCENARIO DESIGN / 01

Spatial perception: from floor zones to event semantics

The on-site question

The same position event means different things in different zones. Passing an entrance may trigger guidance; passing a meeting-room door should not immediately change the room's mode. Spatial perception begins with a map of meaningful zones.

Interaction & system design

Describe spaces through zones, boundaries, entrances and responsive devices. Define arrival, dwell and departure events for each zone, using duration and cooldown conditions to reduce frequent switching. The spatial model does not assume identity recognition.

Validation approach

  1. Confirm zone boundaries and common movement patterns with the site team.
  2. Check whether boundary crossings cause repeated triggers.
  3. Verify that automatic rules do not immediately resume after a manual shutdown.

DEPLOYMENT PLAYBOOK

Site modeling & zone configuration

Deployment begins with a maintainable spatial inventory. Assign identifiers to entrances, dwell zones, corridors and device areas, recording their boundaries, purposes and responsive devices. Prefer anonymous events over identity recognition. When circulation changes, update zone models and device mappings together.

Acceptance replayNormal passage, group dwell, sensor lossValidate fallback behavior and manual shutdown

Exception handling & manual override

Stop automatic rules that depend on an offline device while retaining baseline lighting and manual controls. Give manual overrides explicit priority and recheck device connectivity before restoring automation. Log false, repeated and missed triggers separately rather than masking zone configuration issues with increased sensitivity.

Delivery checklist

  • Zone and device inventory: location, purpose, connection method and maintenance owner.
  • Coordination rules: triggers, cooldowns, priorities and cancellation conditions.
  • Acceptance records: normal flows, exceptions and human takeover replays.
  • Operations manual: inspections, configuration backups, content updates and fault rollback.
