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.

Visual perception, attention, and cognition – very, very basics

Please find below the slides I showed in class today.

But before you do that, please remember to add Deok Gun’s blog to your RSS feed reader. I forgot to add it to my blogroll until now and he complained that he’s very lonely 🙂 Please follow his blog and leave comments for him as well!

Here are the main slides that provided the structure for the class:

Here are the slides about attention. Ignore the first few, they were meant as jokes/examples for a different group.

As examples, if you look at slides 8 and 9 from the attention deck, can you guess what principles I tried to apply there? How do the slides communicate that one set of details is about top-down and the other one is about bottom-up attention (hint: what Gestalt principles are applied there)? How do these two slides attempt to reduce load on working memory?
