Class notes F14 – Week 4: Fundamental principles part 2 of 3

We moved from visual perception and attention to issues related to cognition – specifically, memory and learning.

It should be clear by now that largely, what makes an interface intuitive is its ease of learning. The following concepts are important when it comes to ease of learning:

Here’s Don Norman explaining affordances in less than 2 minutes:

All these things we know about visual perception and cognition are at the root of most guidelines for usable interface design. One of the most famous set of guidelines is Nielsen’s 10 heuristics, which we worked with in class. These heuristics can be used to inspect interfaces in a method called heuristic evaluation, which you will read about for next class.

Please remember to let me know that you read this post by interacting with it somehow. This, as well as participation on the FB group, are requirements for class participation.

Usability heuristics: Debating the fundamentals

You read Nielsen’s 10 usability heuristics and will learn many more design & usability principles in the next two weeks.

After you learn the rules, the next step is to learn how to break them. This UX Magazine post about debating the fundamentals is an example of how to think about breaking the rules. I highly recommend you read it.

What are your thoughts about breaking the rules? Should you? Should you not? When? Why?
