Lean or mean?

Lean or mean?

Image from a flyer by Joscelyn Bingham. The Lean Seat bench, by Joscelyn Bingham, a graduating 3D Design student from University College Falmouth, is a ‘traditionally’ styled slatted wooden alternative to the (usually) unattractive anti-sit perches often found in public places. Note: the surface of […]

Learned down the gambling house

Learned down the gambling house

Michael Shanks’ Ten Things class at Stanford – which looks like a brilliant application of anthropological and archaeological thinking to design and technology – generated a very interesting project by William Choi and Antoine Sindhu analysing the architectures of control (psychological and physical) designed into […]

Design & Punishment

Design & Punishment

Design and Punishment, by Ben Cunningham. Photo from the Arts Institute at Bournemouth‘s 2007 Three Dimensional Design graduate directory. Very neatly linking the themes of the last two posts (devices to make users aware of their energy use, and intentionally uncomfortable seating) is the Design […]

Home-made instant poka-yokes

Home-made instant poka-yokes

Update: Also known as Useful Landmines in the 43 Folders world – thanks Pantufla! Mistake-proofing – poka-yoke – can be as simple as encouraging/forcing yourself to do things in a sequence, to avoid forgetting or avoiding intermediate steps. If you’re the sort of person who […]

Spear’s Spellmaster: Poka-yoke in the classroom

Spear’s Spellmaster: Poka-yoke in the classroom

Back in September we looked at Mentor Teaching Machines, a clever type of non-linear textbook from the early 1970s which guides/constrains the user’s progression, in the process diagnosing some common types of misunderstanding and ‘remedying’ them. The comments were enlightening, too: there’s a lot more […]

Slanty design

Slanty design

The Main Reading Room, Library of Congress. Image from CIRLA. In this article from Communications of the ACM from January 2007, Russell Beale uses the term slanty design to describe “design that purposely reduces aspects of functionality or usability”: It originated from an apocryphal story […]

Do you really need to print that?

Do you really need to print that?

This is not difficult to do, once you know how. Of course, it’s not terribly useful, since a) most people don’t read the display on a printer unless an error occurs, or b) you’re only likely to see it once you’ve already sent something to […]

I believe in mirror-queues

I believe in mirror-queues

Meagan Call has written a very interesting piece examining the technique used in some (women’s) public restrooms* of moving the mirrors to the wall near the entrance/exit, rather than behind the sinks as might be expected (and is usually found in mens’ facilities), to lessen […]

What’s the deal with angled steps?

What’s the deal with angled steps?

It’s a simple question, really, to any readers with experience in urban planning and specifying architectural features: what is the reasoning behind positioning steps at an angle such as this set (left and below) leading down to the Queen’s Walk near London Bridge station? Obviously […]

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 […]

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 […]

How to enjoy taking notes and revising things

How to enjoy taking notes and revising things

It occurs to me that it’s now October, and in Britain that really means the summer’s over (though as I write this it’s pleasantly sunny and crisp outside). And despite attending a lot of very interesting talks and events over the past few months, I’ve […]
