Implementation: Software (DS2OS) DS2OS DS2OS Services OccupancyDetection RoomManager Service Service ------------------------------ -------------------- GalileoGatewayService analyzes manages sensor readings associations to infer occupancy RoomID↔Galileo OccupancyDetectionService timer threshold parameter T if no motion for T seconds SensorGateway Service --------------------- ⇒ unoccupied pulls sensor readings over HTTP RoomManagerService facilitates access to sensors and occupancy state of a room get roomManager/office/occupancy/isOccupied/value Philipp H¨ artinger: Survey and Implementation of Smart Space Scenarios 10
Implementation: Software (UI) Web User Interface HTML & JavaScript queries occupancy states periodically (via RoomManager) colors rooms on map accordingly green = unoccupied red = occupied Philipp H¨ artinger: Survey and Implementation of Smart Space Scenarios 11
Evaluation Experiment 1: controlled experiment in 1 room over 4 hours Expected Results: unoccupied or high activity ⇒ high detection rate occupied, but low activity ⇒ lower detection rate detection rate depends on distance Experiment 2: measurements in 3 rooms over 5 days Expected Results: typical usage patterns of the rooms become inferable Middleware Usage fast and easy implementation due to DS2OS middleware Philipp H¨ artinger: Survey and Implementation of Smart Space Scenarios 12
