Eight design patterns for errorproofing

Eight design patterns for errorproofing

Go straight to the patterns One view of influencing user behaviour – what I’ve called the ‘errorproofing lens’ – treats a user’s interaction with a system as a set of defined target behaviour routes which the designer wants the user to follow, with deviations from […]

Instructable: One-Touch Keypad Masher

Instructable: One-Touch Keypad Masher

It’s been a long time since I last wrote an Instructable, but as I’ve resolved that 2009’s going to be a year where I start making things again (2008 involved a lot of sitting, reading and annotating, and in 2007 most of what I made […]

Staggering insight

Staggering insight

I’ve mentioned a few times, perhaps more often in presentations than on the blog, the fact that guidelines for the design of pedestrian crossings in the UK [PDF] recommend that where a crossing is staggered, pedestrians should be routed so that they have to face […]

What is demand, really?

What is demand, really?

In a lot of the debate and discussion about energy, future electricity generation and metering, improved efficiency and influencing consumer behaviour – at least from an engineering perspective – the term “demand” is used, in conjunction with “supply”, to represent the energy required to be […]

These spikes on a window ledge in Lawnmarket, Edinburgh, look quite old. The ledge is steeply angled, so would be difficult to sit on anyway; if anything they’d make it easier actually to climb up to the window if breaking in were a concern. All […]

No sliding

No sliding

These spikes are embedded every couple of feet in the hand-rails of a staircase at Highbury & Islington station in London, presumably to prevent kids (or adults) sliding down them. They’re not especially sharp, but would bruise someone pretty badly. Note that there are also […]
