Usability Quote of the Day

The prevailing computer-human interaction (CHI) model of interface design has been partly responsible for the current state of the desktop computer. The breakthrough on which the field emerged was the admission of psychological principles. The resulting graphical user interface has been the focus of the field of computer-human interaction for nearly 20 years. This interface is a virtual control panel whose design has remained quite technology-centered. -- Malcolm McCullough, Digital Ground, 2004    (via interaction-design.org)

Balancing fidelity in prototyping

Striking the right balance of prototype detail ...

"Choosing the right level of graphic detail, interactivity, breadth and depth.

Deceived by their ideas of what clients will accept, many web development teams build prototypes that are too costly and doesn't serve the purpose prototypes are supposed to. To exploit the full potential of prototyping, it's critical to choose the appropriate level of fidelity.

Some projects put an undue emphasis on certain aspect of prototypes, such as the graphic design or the implementation of advanced functionalities. Often they don't want to show clients something that appears unfinished. Fact is that prototypes by definition are unfinished, and if you start building prototypes that are highly detailed, things quickly gets overly costly and time consuming."   continued ...   (Via GUUUI)
