Heating debate

Heating debate

Central heating systems have interfaces, and many of us interact with them every day, even if only by experiencing their effects. But there’s a lot of room for improvement. They’re systems where (unlike, say, a car) we don’t generally get instantaneous feedback on the changes […]

Angular measure

Angular measure

A few years ago I went to a talk at the RCA by Alex Lee, president of OXO International. Apart from a statistic about how many bagel-slicing finger-chopping accidents happen each year in New York city, what stuck in my mind were the angled measuring […]

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 […]

Placebo buttons, false affordances and habit-forming

Placebo buttons, false affordances and habit-forming

This is a great graph from GraphJam, by ‘Bloobeard’. It raises the question, of course, whether the ‘door close’ buttons on lifts/elevators really do actually do anything, or are simply there to ‘manage expectations‘ or act as a placebo. The Straight Dope has quite a […]

Invitation to participate

Invitation to participate

For the last few weeks I’ve been setting up and running the first few trials of the ‘Design with Intent Method’, the design/innovation tool I’ve (embarrassingly sporadically) talked about on the blog over the last year. It’s essentially an innovation method to help designers given […]

Sort some cards and win a copy of The Hidden Dimension

UPDATE: Thanks everyone – 10 participants in just a few hours! The study’s closed now – congratulations to Ville Hjelm whose book is now on its way… If you’ve got a few minutes spare, are interested in the Design with Intent techniques, and fancy having […]

Modelling users: Pinballs, shortcuts and thoughtfulness

Modelling users: Pinballs, shortcuts and thoughtfulness

The different approaches to influencing people’s behaviour outlined in the Design with Intent toolkit are pretty diverse. Working out how to apply them to your design problem, and when they might be useful, probably requires you, as a designer, to think of “the user” or […]

The ‘You Are Here’ Use-mark

The ‘You Are Here’ Use-mark

Who really needs a “You Are Here” marker when other visitors’ fingers have done the work for you? (Above, in Florence; below, in San Francisco) Use-marks, like desire paths, are a kind of emergent behaviour record of previous users’ perceptions (and perceived affordances), intentions, behaviours […]

frog design on Design with Intent

frog design on Design with Intent

Robert Fabricant of frog design — with whom I had a great discussion a couple of weeks ago in London — has an insightful new article up at frog’s Design Mind, titled, oddly enough, ‘Design with Intent: how designers can influence behaviour’ — which tackles […]
