Do it yourself mobile usability testing at EuroIA 2010 Presentation Transcript

  • 1. we are ...
  • 2. Bernard, packet core engineer at NSN
  • 3. Belén, interaction designer at LBi UK
  • 4. the proverbial poll
  • 5. how many have observed a mobile usability testing session?
  • 6. how many have planned or moderated mobile usability testing?
  • 7. usability testing a process that employs people as testing participants who are representative of the target audience to evaluate the degree to which a product meets specific usability criteria. Handbook of usability testing 2nd Ed., J. Rubin and D. Chisnell
  • 8. why recording? no need to rely on notes and memory a powerful communication means
  • 9. actions reactions
  • 10. dut = mut
  • 11. dut = mut + afec where: dut = desktop usability testing mut = mobile usability testing afec = a few extra challenges
  • 12. which phone? which context? which connection?
  • 13. which phone? which context? which connection?
  • 14. web task success rates feature phones 38% smartphones 55% touch phones 75% Mobile usability, J. Nielsen’s Alertbox 20 Jul 2009 http://www.useit.com/alertbox/mobile-usability.html
  • 15. web task success rates feature phones 38% smartphones 55% touch phones 75% Mobile usability, J. Nielsen’s Alertbox 20 Jul 2009 http://www.useit.com/alertbox/mobile-usability.html

  • 18. handset usability affects test results
  • 19. remember... test with participants’ own phones if not possible, include training and warm-up tasks
  • 20. which phone? which context? which connection?
  • 21. field vs. lab It’s Worth the Hassle! The Added Value of Evaluating the Usability of Mobile Systems in the Field C.M. Nielsen, M. Overgaard, M.B. Pedersen, J. Stage, S. Stenild - NordiCHI 2006
  • 22. experts disagree according to our study there was no difference in the number of problems that occurred in the two test settings. Our hypothesis that more problems would be found in the field was not supported Usability Testing of Mobile Applications: A Comparison between Laboratory and Field Testing A. Kaikkonen, T. Kallio, A. Kekäläinen, A. Kankainen, M. Cankar - Journal of Usability Studies, 2005
  • 23. experts disagree evaluations conducted in field settings can reveal problems not otherwise identified in laboratory evaluations It’s Worth the Hassle! The Added Value of Evaluating the Usability of Mobile Systems in the Field C.M. Nielsen, M. Overgaard, M.B. Pedersen, J. Stage, S. Stenild - NordiCHI 2006
  • 24. but they all agree evaluations in the field (are) more complex and time-consuming It’s Worth the Hassle! The Added Value of Evaluating the Usability of Mobile Systems in the Field C.M. Nielsen, M. Overgaard, M.B. Pedersen, J. Stage, S. Stenild - NordiCHI 2006 testing in the field requires double the time in comparison to the laboratory Usability Testing of Mobile Applications: A Comparison between Laboratory and Field Testing A. Kaikkonen, T. Kallio, A. Kekäläinen, A. Kankainen, M. Cankar - Journal of Usability Studies, 2005
  • 25. testing in the lab is better than no testing
  • 26. remember... for most software, lab testing is fine if you must do field testing... do it late plan and run pilot tests be prepared (like the Scouts)
  • 27. which phone? which context? which connection?
  • 28. http://www.coveragemaps.com/gsmposter_europe.htm
  • 29. state of coverage: UK mobile coverage for 2G is extensive at 98%. The picture for 3G coverage is different. Figures are high overall (87%), but vary markedly in the nations, with only 43% availability in Northern Ireland Mobile Evolution - Ofcom’s mobile sector assessment - 17 December 2009 (p35) http://stakeholders.ofcom.org.uk/binaries/consultations/msa/statement/MSA_statement.pdf
