- The task was for me to evaluate the class website using Norman concepts. I did my evaluation using concepts such as the three levels of processing, gulf of execution, affordance, signifiers, and conventions. I ended up presenting my evaluations to the class using powerpoint. I learned more about how the design of a website can be broken down into certain concepts and how they all inter-relate with one another. The project has opened my eyes to a new perspective when using websites in the future.
