  1. Usability and AccessibilityLecture 15 – 13/04/10 Dr. Simeon Keates

  2. Exercise • On Tuesday(-ish) you performed a pilot study • Today, make any changes you identified to your usability protocol • Also, make any changes to your web-site based on the feedback that you obtained • Please mail your finalised protocols to Susanne and me

  3. Final reports and presentations You have to produce 3 things: • 1 – Formal project report • 10 page ACM conference publication format • http://www.sigchi.org/chipubform/ • 2 – “Glossy” report selling the site • Show the board why this is a good design • e.g. Why users would want to come to the site and trust it • 3 – Group presentation • Explain your reports • Highlight the findings that you think are particularly important

  4. Glossy report • No particular structure • “Sell” your site to your client • Explain aesthetic choices, etc. • Cover anything you want to draw attention to that is not in your formal report

  5. Formal report • This is a project report, not a usability report • Structure your report like a scientific report (see earlier lecture notes) • The aim of the report is to show that: • You know what factors affect the usability and accessibility of a web-site • You set up appropriate experiments to inform your re-design process • You can explain and justify all design decisions made • You can identify and recommend potential improvements to your site

  6. Example formal report structure • Abstract • Executive summary of the report • Introduction • What you are writing about and why • What research questions you are asking (ideally posited as hypothesis) • Example hypothesis: The revised site offers faster task completion times than the original site • Example hypothesis: The revised site is more accessible [define this!] than the original site • Background • Talk about the design of the original site • Why did you design the site the way that you did?

  7. Example formal report structure • Method • Describe each of the experiments that you performed on your site • Examples: Heuristic analysis, pilot study, exclusion analysis, accessibility checkers, personas, etc. • Describe how you did each of these (e.g. describe the users, etc.) • Describe your final “verification” user trials • Include user profiles (ages, etc.) • Results • Describe the results and observations from your user trials • What data did you collect? • Quantitative and qualitative

  8. Example formal report structure • Discussion • What did you learn from the user trials? • Did the data you collected help you answer the research questions that you posed? • [Note: they should have done] • Conclusions • Did the usability and accessibility of the site improve? • Did the different experiments that you performed help improve the design of your site?

  9. Example formal report structure • Further work • Are there further studies you would like to perform on your site? • What further changes would you make to the design of your site based on your user trials? • Explain and justify your answers to these questions
