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

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

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

Smart Space Configuration Event Recorder Fact description Patterns Subscription Notification Event Log Saving

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

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!
