Das hier ist ein etwas oberflächlicher, aber dennoch ganz interessanter Artikel: A basic usability test on ten phones.
We tested ten phones, and in all cases I made sure the phone had a connection and was on the home screen. After that I handed it over. The original plan was not to offer B. any further help, but pretty soon it turned out I had to teach him how to zoom. Not only was he completely unacquainted with any kind of zooming, but the eight phones that have zooming capability use five different mechanisms.
Na ja. Man kann man kurz drüber schauen.
