  1. Project 6: Usability and Utility of a Network Visualization of Document TopicsInitial Presentation Gill, Amandeep Singh   Gulati, Vrishti Mesple, Eric   Yang, Xinxin

  2. OVERVIEW

  3. TopicNets- Interactive Topic-based Data Exploration Visualization of topic clusters extracted from large documents through similarity analysis of text documents.

  4. Features 1. Visualize result of     text-based search 2. Temporal Layout 3. Topic-based Deformation 4. Customized scheme     (colors, threshold, size) 

  5. USABILITY ISSUES

  6. Usability Issue 1(Our View) • The layout of user interface is not structured well.

  7. Usability Issue 2 (Our View) • No proper description of tabs      and functionalities

  8. Usability Issue 3 (Our View) • Too much unwanted information • simple mode for unprofessional users • expert/full mode for advanced users

  9. Methods and Approaches Finding a solution to our HCI problem

  10. Phase 1 (week 4-5)Initial Interview •  Why?      • Form user groups  • Complexity of program  • Scope of problem not clear • Questions abstract • Lots of information • How? • Identify the objectives • Prepare sample questions. • Identify method to analyze. • Sample Questions: What do you think of these types of programs?      Interviewers: All

  11. Phase 2 (week 5)Deciding Users  Data collected from interviews:  - prior knowledge - education - experience - frequency of use Help placement of users into subgroups.  Formulate tasks for different subgroups. Example: based on the information, we can form 2 subgroups 1- undergraduate (3-5 users) 2- graduate and faculty (3-5 users)

  12. Phase 3 (week 5-6)Deciding tasks for groups Everyone does simple mode(basic and intermediate tasks). Based upon results from initial interview, specific participants(experienced users) perform additional advanced tasks. Researchers Basic level task                                 Eric Intermediate level task                   Amandeep Advanced level task                    Vrishti & Xinxin

  13. Phase 4 (week 7)Pilot Test • Prepare test environment • Preliminary usability test • Make sure the goals of our tests are met 

  14. Phase 5 (week 7-8)Implementing Test • Test administration (Tutorials,scenario description,timelines) • Video recording • Screen recording • Present task environment • Tutorial (half an hour) • Conduct experiment (half an hour for basic task, additional half an hour for advanced task)

  15. Phase 6 (week 9-10)Analyzing Data & Provide Recommendations • Analyze data based on the usability test. • Proposed recommendations • Dialogue with John • Final report

  16. Task Timeline Roles Initial Interview Week 4-5 All Deciding users/form Subgroups Week 5 All Deciding on specific tasks for subgroups Week 5-6 Eric = Basic level tasksAmandeep= IntermediateXinxin&Vrishti= Advanced Pilot Test Week 7 Eric and who ever else can help Implementing Test Week 7-8 Eric= Tutorial/training Amandeep= scenario descrp. Xinxin= Video recording Vrishti= Test administrator Analyzing Data and Provide Recommendations Week 9-10 All
