Computerized System to Enhance Situation Awareness: Key Challenges Associated with the Design, Evaluation, and Extension of a Prototype

  1. 1. Computerized System to Enhance Situation Awareness: Key Challenges Associated with the Design, Evaluation, and Extension of a Prototype Yasir Javed* & Tony Norris** *COMSATS Institute of Information Technology, Abbottabad, Pakistan **School of Engineering and Advanced Technology, Massey University, Auckland, New Zealand
  2. 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. 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 Slide 3 from 14
  4. 4. SAVER Design and Development Contextual SA Slide 4 from 14
  5. 5. SAVER Architecture Slide 5 from 14
  6. 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 Slide 6 from 14
  7. 7. SAVER Interface Slide 7 from 14
  8. 8. SAVER Evaluation Construct Measured Mean % situation awareness using SAVER Mean % situation awareness not using SAVER t-value p-Value Individual SA 82.6 73.0 2.84 p = 0.008 Shared SA (SSA) 78.5 67.3 5.95 p < 0.001 Team SA (TSA) 81.9 59.5 4.50 p = 0.003 Combined SA (TSA) 91.8 83.4 4.42 p = 0.003 Slide 8 from 14
  9. 9. Extending the SAVER Prototype • Trust Development • Testing with Actual (Large)Data Sets • Human Computer Interface Requirements Analysis • Challenges o Organizational o Architectural o Functionality o Display and interaction Slide 9 from 14
  10. 10. Organizational Changes • Multi-organization Integration • Level of Information sharing – New policies • Process Re-Engineering (Change Management) • Emergency Managers and Training • In-depth Information requirements for organizations Slide 10 from 14
  11. 11. Architectural Challenges Slide 11 from 14
  12. 12. Functionality Challenges • Option Handling • Cloud Computing • Sensor Input • Security • Testing Slide 12 from 14
  13. 13. Display and Interaction Challenges • Graphical User Interface (GUI) requirements • SA, SSA and TSA Oriented Visualisations • Query Visualisation • Visual Analytics • Touch Screens • Mobile Devices Slide 13 from 14
