Getting someone to do things in a particular order (Part 3)
Continued from part 2 This series is looking at what design techniques/mechanisms are applicable to guiding a user to follow a process or path, performing actions in a specified sequence. The techniques fall roughly into three ‘approaches’. In this post, I’m going to examine the […]
Salt licked?
UPDATE: See the detailed response below from Peter of Gateshead Council, which clarifies, corrects and expands upon some of the spin given by the Mail articles. The new shakers were supplied to the chip shop staff for use behind the counter: “Our main concern was […]
Hard to handle
British Rail’s drop-the-window- then-stick-your-hand-outside- to-use-the-handle doors puzzled over by Don Norman in The Design of Everyday Things are still very much around, though often refurbished and repainted as with this delightful/vile pink First Great Western-liveried example. I’m assuming that this design was intended to introduce […]
Portioning blame
McDonald’s, Toledo, Ohio, 1967. Image from DRB62 on Flickr. We’ve looked previously at the effect of portion/packaging sizes as a ‘choice of default’ architecture of control, and I’m aware that I have not yet reviewed Dr Brian Wansink‘s excellent Mindless Eating, which examines this and […]

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 […]
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 […]
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 […]
Making exercise cooler
Main image and above right: Snowdown aesthetic model; below right: Snowdown functional test rig prototype. Snowdown, by Matthew Barnett, is fantastic. Powered by a child exercising, moving the handle, it crushes ice cubes and compacts them to make snowballs. There are a lot of kids […]
The Terminal Bench
Mags L Halliday – author of the Doctor Who novel History 101 – let me know about an ‘interesting’ design tactic being used at Heathrow’s Terminal 5. From the Guardian, by Julia Finch: Flying from the new Heathrow Terminal 5 and facing a lengthy delay? […]
