Transcript

  • 1. IM2044 – Week 12 Dr. Andres Baravalle
  • 2. Before we start • As I mentioned in class on Friday, I will not be able to teach the class on Friday 10th May • After discussing with the students in class, you will be able to take the class on any one of these dates: – Thursday 9th May in ITC09 at 13:00 OR – Tuesday 14th May in ITC02 ITC07 at 10:00
  • 3. Lecture content • Don’t make me think! • Feedback • 2012-2013 dissertation supervisions 3
  • 4. Usability heuristics • The first law of Usability Engineering (according to Steve Krug) is... • Don’t Make Me Think 4
  • 5. #1: Users don’t read web pages • Users don’t read web pages – they just scan 5
  • 6. #2: Don’t make optimal choices • Optimal choices are in most cases a waste of resources • Typically is not needed to commit the resources needed to have an optimal interface rather than a good interface – People don’t look for perfect plans – they look for good enough plans – Are you really going to look for a second price when you find a book in Amazon at £ 3? 6
  • 7. #3: Users have no understanding of how things work • Nor they should need to, in many cases – Knowing the TCP/IP stack is not going to help you to send an email • Don’t design interfaces that require learning from users – most probably users are NOT going to learn how to use your interface 7
  • 8. The trunk test • Imagine you are blindfolded in the trunk of a car • Driven around • Dumped somewhere – Once you are out, you need to assess your situation 8
  • 9. The trunk test (2) • A usable web site will allow you to “survive” a trunk test • On a usable web page you’ll be always able to answer these questions: – – – – – – What site is this What page I’m on What are the main sections What are my options Where I am How can I search 9
  • 10. The trunk test (3) • You can use this approach by printing a set of pages and asking users to circle some or all of those areas • You can compare user’s performance on different web pages to have an indicator of their usability 10
  • 11. Designing home pages • A typical home page will include: – – – – – – – – Site identity and mission Site hierarchy Site search Teases (e.g. Featured content) Timely content Deals (including ads) Shortcuts to content Registration • A home page should always pass the “trunk test”! 11
  • 12. Usability evaluation methods • Usability inquiry: focus on talking to and/or observing users • Usability inspection: focus on expert analysis • Usability testing: focus on testing interfaces with users 12
  • 13. Always, always, always TEST • Testing one user is better than testing none! 13
  • 14. Test soon, test often • Testing one user early is better than testing 50 at the end 14
  • 15. Testing is iterative • No point in testing if you don’t correct the errors that you find... 15
  • 16. And this is (nearly) the end... 16
  • 17. Feedback • Module feedback available on UELplus • Please submit the feedback – let us know what you liked and how we can improve 17
  • 18. Bibliography • Krug, S. (2009) Don’t Make Me Think 18
  • 19. SUPERVISIONS 19
  • 20. Final year supervision • This is for September 2014 • I’m happy to consider supervising (in 2013-2014) students in the following areas: – Web APPLICATIONS development – Open Source technologies – Usability, accessibility and HCI 20
  • 21. Remember! • It’s your research/dissertation – you have to pick something that you enjoy – I’m open to supervise thesis in my areas of interest – I’m not interested in supervising thesis that are not interesting for me too 21
  • 22. Supervision meetings • I hold all my supervision meetings on one day (currently Tuesdays) –It is not negotiable • If you are not free on that day I cannot supervise you 22
  • 23. Where to find more • A selection of available dissertation topics is available here: baravalle.com/teaching You can write me at a.baravalle@uel.ac.uk 23
