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.
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.
or not a Spitfire?
- see page 49. Design Focus: Human error and false memories
Well it did seem such a good story we told in the second edition,
the Spitfire with a confusing ejector seat button ... but unfortunately
not quite accurate!
strange story of Draken Sierra 44
- This is the full story of the ill fated Draken and its drop tanks.

- see box page 115. Computer speeds and capacities are increasing
exponentially - what does this mean for the user and where is
it leading us?
probes - methods to study new environments
- see page 200. Design Focus: Cultural probes
- Technology probes are a means for users and designers to envisage radically new technology or applications through the use of early high-fidelity prototypes.
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.
Eye contact in recorded video
- A simple tip to help mainain appropriate eye contact and gace direction when creating prerecorded video for education or presentations.
Just try it once – (very) early evaluation
- An unsuable coffee grinder reminds us that some faults just need us to try things out.
Ghost Orders – getting the job done
- When new systems do not match working practices, those on the ground develop workarounds, tweaks and subversions of the systems in order to 'get the job done'.
Values, Conflict and Cows
- Different stakehoders may have different value systems. Do we use technology to help resolve conflicts or to simply allow the dominant party to exert power through the technology?
- Some lessons about designing novel technology ... from a paper printout.
War stories: lessons from UI disaster stories
- Things go wrong in even the most large-budget, popular products. Here are links to some of Alan's blog posts about times when things went wrong, and some of the the ways you can prevent this happening to the systems you design.
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.
