Novell's Releases Linux Usability Testing Videos
sp3298622 writes "Novell is releasing primary desktop research, including over 200 videos and analysis of usability tests, at betterdesktop.openSUSE.org. Vice president of collaboration and desktop engineering for Novell, Nat Friedman: As a programmer, it's sometimes difficult to know how ordinary people with no technical experience are reacting to your software. Linux people tend to know other Linux people. In these usability tests, we selected test subjects who were experienced with Windows, but who had never heard of Linux, and asked them to perform basic tasks using the Linux desktop."
Try to find Jacob Nielsen's "Why You Only Need to Test With 5 Users" or "A mathematical model of the finding of usability problems" for some more insight into population size for usability testing.
