Smart Room System Smart Room in PetrSU Project is intended for automated conduction of: conferences and meetings seminars and trainings lectures and labs SR system exploits the Smart Space concept and Smart-M3 platform Ivan Galov Event Recording in Smart Room 25.04.2013 3 / 14

Smart Room System SmartRoom Functions Automatic registration of participant presence Presentation and conference management using mobile device Measurement of room physical characteristics Providing feedback through blogging Ivan Galov Event Recording in Smart Room 25.04.2013 4 / 14

Smart Room System Smart Room Service Architecture Services allow users to interact with the Smart Room and obtain different information Users access services via personal mobile devices Every service is a data source that can be processed and visualized External services KP google scholar Blogging services Smart Space Internal services SmartScribo Event Recoder KP tracking BlogClient BlogMediator + user activity Report Generator BlogProcessor Conference services Sensor services Management-service Temperature sensor Light sensor Agenda-service Projector-service Others sensors ...

Event Recorder System Event Recording Event definition Data change in smart space identifies event Subset of data in smart space describes event Interval definition Event registration indicates interval start Another event registration indicates ending Intervals may have internal events and intervals Ivan Galov Event Recording in Smart Room 25.04.2013 6 / 14

Event Recorder System Event Visualization in Smart Room Visualization of events happenned during the conference allows: clearly see the time of event occurence depict relations between events produce summary reports for analisys debugging cooperation between Smart-M3 agents Ivan Galov Event Recording in Smart Room 25.04.2013 7 / 14

Event Recorder System Event Recorder Lifecycle Read event description from configuration file Setup subscriptions to smart space Upon recieving notification from SIB, register event and retrieve event description from smart space If interval is started, setup subscriptions for internal facts Write information into output file Configuration Fact description Event Saving Event Log Subscription Smart Space Recorder Notification Patterns Ivan Galov Event Recording in Smart Room 25.04.2013 8 / 14

Systems Integration Smart Room Event List We decided to track the following events: Conference start Conference end Presentation start Presentation end Slide change Participant presence New message recieved through the blog service Ivan Galov Event Recording in Smart Room 25.04.2013 10 / 14

Systems Integration Systems Integration Scheme Ivan Galov Event Recording in Smart Room 25.04.2013 11 / 14

Systems Integration Visualization: Mind Map Mind Maps display events as a graph Suits best to display complex hierachical events Ivan Galov Event Recording in Smart Room 25.04.2013 12 / 14

Systems Integration Visualization: Timeline Timeline displays events in sequental order Suits best to display parallel and lasting processes Ivan Galov Event Recording in Smart Room 25.04.2013 13 / 14

Conclusion Results Generalization of event recording features to any smart space application Integration of the event recording features into the Smart Room system Producing summary reports on held events in two formats: mind map and timeline Further development: support online visualization when reports are formed on-the-fly and immediately provided for public observation Thank you for attention!
