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
please, stand up
   everyone
sit down if you don’t
have a US cellphone
   with a data plan
sit down if you don’t
      like beer
sit down if you are
absolutely terrified by
the idea of being our
     test subject

where:

mut = mobile usability testing
afec = a few extra challenges

 warm-up tasks

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
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
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
but they all agree
evaluations in the field (are) more
complex and time-consuming

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

testing in the lab is
better than no testing
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)

but ...

  intrusive, uncomfortable and heavy
2. screen-capture applications

need to have firm foundations, solid

expect the same of emerging mobile
