2. Overview
• Situation Awareness in Emergency Management
• SAVER Prototype
o Design and Implementation Challenges
o Evaluation Challenges
• Extending SAVER as a Production System
o Design and Implementation Challenges
Slide 2 from 14

3. Situation Awareness in
Emergency Management
• Situation Awareness (SA)
o Result of understanding the situation (Situation assessment)
o Provide basis to decide the actions needed to normalise the situation
o Perception, Comprehension and Projection
• Shared Situation Awareness (SSA)
o Overlap (commonality) in the SA of team members
• Team Situation Awareness (TSA)
o SA required for own / team responsibilities in relation to the team goal
o Total (combined) SA of team members
o Belief about own and team members’ SA

Contextual SA
Slide 4 from 14

5. SAVER Architecture
Slide 5 from 14

6. SAVER Functionality
• Goal Directed to Improve Decision Making
• Displays Information to Reduce User Processing
• Proactive Sharing of Information to Enhance SA
• Enhances all Types and Levels of SA
• Uses Ontology to Infer Future Situations
