New Conclusions in Usability Testing

Usability testing studies...

"July's issue of the UI Design Newsletter looks at how recent usability research is leading to new conclusions which may have implications for tried-and-true usability testing techniques.

In particular, a couple of questions they posed and their answers caught my attention:
Does it matter if you test with lo-fi or hi-fidelity prototypes?

A recent study suggests neither but instead to use a mixed fidelity approach based on the application of 5 'dimensions' to your prototype:
level of visual refinement
breadth of functionality
depth of functionality
richness of interactivity
richness of data model

In this way, the purpose of the test determines the level of fidelity used as far as each of the above attributes is concerned."   (Continued via smiley cat)       [Usability Resources]
