  1. Interface Redesign of Flight Reservation Systems Nicholas R. Jones Chris S. T. Fernandes Computer Science Union College

  2. Human Computer Interaction • Usability Analysis • Flight Reservation System Nicholas R. Jones

  3. Outline • Motivation • Existing Solutions • Goals • Evaluation Process • Results • Conclusion Nicholas R. Jones

  4. Motivation • Easy for anyone to make an interface • Some are not intended for human consumption • Interfaces that are not tested Nicholas R. Jones

  5. Existing Solutions • Travel Sites: • Travelocity • Orbitz • Expedia • Focusing on Flight Reservations Nicholas R. Jones

  10. Goals • 1.) Time to learn • 2.) Speed of performance • 3.) Rate of errors by users • 4.) Retention over time • 5.) Satisfaction • Shneiderman, Ben. Designing the User Interface. Third Edition. Reading, MA: Addison Wesley, 1998. p 15 Nicholas R. Jones

  11. Evaluation Process • Test on Users • Analyze data to find where problems occur • Suggest multiple ways to fix problems • Test for best solutions • Incorporate solutions in redesign • Run user evaluation again Nicholas R. Jones

  12. Methods • Usability Analysis • Scenarios • Timing and Noting • “Thinking-Aloud Protocol” • Surveys • Automated Testing • Collect various information remotely Nicholas R. Jones

  13. User Test 1 • 6 participants tested • Each participant – 3 scenarios • Frustrating Issues • Waiting and re-entering data • Distinguishing between different flight • Date and time inputs Nicholas R. Jones

  14. User Test 2 • Entering in Dates • Calendar Input • Pull-Down Menus • Text in MM/DD/YY format • Re-entering in Data • Left, Right, or Bottom Nicholas R. Jones

  15. Test 2 results • Pull down menus were significantly faster than calendar input • Inputting into the Left and the Bottom was significantly faster and more satisfying than on the Right • N=49 participants Nicholas R. Jones

  16. User Test 3 • Nine students tested several interfaces using three scenarios. • Fictional FlightGuide.com site • Travelocity, and Orbitz used for comparisons Nicholas R. Jones

  17. Input Screen • Round trip /one way needs to be clearer • before/after/around helpful if noticed • A method to see flight duration before results • Results Screen • Sort by flight length, start time, price • Total flight duration • Results kept together and not separated Nicholas R. Jones

  18. User Test 4 • 5 students participated • Used fictional FlightGuide.com site Nicholas R. Jones

  19. Input Screen • missed one way/round trip still, did not like in middle • liked trip duration • Half used before/around/after • Results Screen • Did not notice sort by fields • Would like an overview of results • Easier way to track results. (color code) Nicholas R. Jones

  20. Conclusions • Information Visualization • Search • Overview • Zoom and Filter • Details on Demand • Asking users is not enough Nicholas R. Jones

  21. 5 users is enough http://www.useit.com/alertbox/20000319.html Nicholas R. Jones
