ICT325 Human Computer InteractionAssignment 1-1 Using a contingent heuristic approach for the usability evaluation of web sites A case study of Flash vs. HTML-based web sites Pilun Piyasirivej DIT Candidate, Murdoch University

ICT325 Human Computer InteractionAssignment 1-2 Purpose of the research Contingent heuristic approach (WUCET) can be effectively used to evaluate the usability of web sites Usability of Flash vs. HTML-based web sites still in question Many web sites contain both Flash and HTML versions High maintenance costs, inconsistencies WUCET generates relevant usability statements for each web site that can be rated by the users

ICT325 Human Computer InteractionAssignment 1-3 Structure of the survey Two groups of participants: (a) Flash (b) HTML Each participant visits six web sites, either all in Flash or all in HTML (randomly assigned) Find information from each web site to answer the questions provided Evaluate the usability of these web sites by rating your agreement with the statements provided For each statement, you can select: strongly disagree, disagree, neutral, agree, and strongly agree Option to provide your comments about the ease of use of these web sites in your own words

ICT325 Human Computer InteractionAssignment 1-4 How to complete the survey 1.Complete the consent form and submit it to Andrew or Diana 2.Submit your name and at before 20 March 3.You will receive an from Pilun before 22 March, otherwise please contact Pilun Andrew, or 4.Complete the survey before 1 April 5.Complete the assignment and submit it (with completed handout) by 7 April

ICT325 Human Computer InteractionAssignment 1-6 Background information

ICT325 Human Computer InteractionAssignment 1-7 Procedures for each web site First, click the link provided, it will open a web site in a new window (you should maximize it) If and only if you cannot view the web site for any reason, select “no” to the question “Could you view…web site?” then state the reason and continue to the next web site

ICT325 Human Computer InteractionAssignment 1-8 Procedures for each web site (cont’d) Start the timer at the top left of the window Find information on the web site and answer the questions provided in the handout Stop the timer and write down the time you used on the space provided in the handout

ICT325 Human Computer InteractionAssignment 1-9 Procedures for each web site (cont’d) Rate the statements provided in the handout and write comments in your own words in the box at the bottom of the sheet Go back to the online survey and select “yes” to the question “Could you view… web site?” and copy your responses from the handout into the online survey Click “Next” to proceed to the next web site. When you finish all web sites, click the “Submit” button
