An Introduction to SI Metric and Applications of SI Metric, published by Mentor Textbook Teaching Machines of London, 1971. Back in January, in a post looking at the use of forcing functions in education, I mentioned a type of textbook I remembered having somewhere which […]
Biting Apple
Interesting to see the BBC’s summary of the current iPhone update story: “Apple issues an update which damages iPhones that have been hacked by users”. I’m not sure that’s quite how Apple’s PR people would have put it, but it’s interesting to see that whoever […]
Friday quote: Friction
“If the point of contact between the product and the people becomes a point of friction, then the Industrial Designer has failed.” Henry Dreyfuss, Designing for People, 1955 Cognitive friction is one thing, and generally a result rather than a deliberate strategy; process friction is […]
Water on the membrane
The Cranfield/Electrolux Smart Sink – photo from Trespassers by Ed van Hinte and Conny Bakker. Ten years ago, teams from Cranfield University and Electrolux Industrial Design collaborated on an ‘eco-kitchen’, a family of related concepts for a kitchen of the future. Part of the intention […]
Some thoughts on classifications
Over the last couple of years, this site has examined, mentioned, discussed or suggested around 250 examples of ‘control’ features or methods designed into products, systems and environments – many of which have come from readers’ suggestions and comments on earlier posts. I’d resisted classifying […]

Around ten months ago, this site was accepted into 9rules, a diverse network of blogs which, at the time, had this aim: 9rules is a community of the best weblogs in the world on a variety of topics. We started 9rules to give passionate writers […]
Pier pressure
  Deliberately routing users via a longer or more circuitous route is found in many forms (with a variety of intentions) from misleading road signs, to endless click-through screens, splitting up articles, periodic rearrangement of supermarket shelves, and so on. This kind of forcing function […]
Cleaning up with carpets
Following the recent post looking at aspects of casino and slot machine design, in which I quoted William Choi and Antoine Sindhu’s study – “[Casino] carpeting is often purposefully jarring to the eyes, which draws customers’ gaze upwards toward the machines on the gambling floor” […]
Normalising paranoia
This is brilliant. Chloë Coulson, Erland Banggren and Ben Williams, three Ravensbourne graduates, have put together a project looking at the “culture of fear”, the media’s use of this, and how it affects our everyday state of mind. The outcome is a catalogue, WellBeings™ [PDF […]
Changing behaviour: water meter taps
Three student projects on show at Made in Brunel earlier this month took the idea of moving the function of a water meter to the tap (faucet) itself, to act as a ‘speedometer‘ and thus encourage users to reduce their water usage (or wastage). The […]
Ticket off (reprise)
Last year we looked at the way that the pricing structure of no-change-given ticket machines is often – apparently – designed to lead to overpayment, and I posed the question of whether councils/car park operators actually draw up their budget based on a significant proportion […]
Bad profits
The Gillette Sensor Excel not only comes with a dummy blade, it also only comes with two out of five possible blade slots filled. Images from Sevenblock on Flickr. The razor-blade model in general is something of an old chestnut as far as architectures of […]
