why study human–computer interaction?  - This video looks at a variety of examples to explore the different reasons why human-computer interaction is an important and exciting area to study.
-
making the most of stakeholder interviews
- Working with stakehoders takes a lot of organising and consumes both your tmem and theirs. Make the most of the precious time you have with them.
-
act it out
- Reading a scenario can be helpful, as can talking through a user's activities in an interview. However, sometimes physically acting things out adds an extra dimension.
-
early lessons: it's not all about technology
- Lessons from an 1960s Systems Analysis book - why it's important to watch the users, and problems aren't always solved with a computer.
-
how many computers?
- see exercise page 60.
How many computers do you have in your home?
How many computers do you normally carry with you in your pockets or bags?
-
desire and disaster
- There are always more things you would like to do when creating or updating a system: problems to fix, new features to add, ways to make what you have easier to use, more slick, more appealing. How do you choose which to do first?
-
are five users enough?
- Along with Fitts’ Law and Miller’s 7+/-2 this “five is enough” must be among the most widely cited, and most widely misunderstood and misused aphorisms of HCI and usability.

Spitfire
or not a Spitfire?
- see page 49. Design Focus: Human error and false memories

-
Cybernetic Understanding of Fitts' Law
- Fitts' Law is perhaps the most commonly known 'law' of psychology
used in HCI, but why is it true and what are its limitations?
-
- see page 200. How to choose the best trade-off between menu breadth and dpeth, and why Miller's 7+/-2 is not the way to do it.

Gmail – colours in a mess
- Sometimes even major internet companies make simple, yet serious mistakes. In this short case study we see how easy it is to mess up colours not only making text unreadable, but potentially undermining the confidence of users in your message.
