OVERVIEW

 

TopicNets- Interactive Topic-based Data Exploration

Visualization of topic clusters extracted from large documents through similarity analysis of text documents.

Features

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

USABILITY ISSUES

 

Usability Issue 1(Our View)

• The layout of user interface is not structured well. 

Usability Issue 2 (Our View)

• No proper description of tabs      and functionalities

Usability Issue 3 (Our View)

• Too much unwanted information• simple mode for unprofessional users• expert/full mode for advanced users

Methods and Approaches  

Finding a solution to our HCI problem

Phase 1 (week 4-5)Initial Interview•  Why?     

1.Form user groups 2.Complexity of program 3.Scope of problem not clear4.Questions abstract5.Lots of information

 • How?

1.Identify the objectives2.Prepare sample questions.3.Identify method to analyze.

 • Sample Questions: What do you think of these types of

programs?     Interviewers: All

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 subgroups1- undergraduate (3-5 users)2- graduate and faculty (3-5 users)

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.                                                    ResearchersBasic level task                                 EricIntermediate level task                   AmandeepAdvanced level task                    Vrishti & Xinxin  

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

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)

Phase 6 (week 9-10)Analyzing Data & Provide Recommendations

 • Analyze data based on the usability test.• Proposed recommendations• Dialogue with John• Final report
