Errornomics?!

Friday, March 20th, 2009

I was intrigued and amused this week to see a book review in The Independent newspaper for “Why We Make Mistakes” by Joseph Hallinan, a Pulitzer prize-winning journalist, no less. Sounds great, I thought, and right up my street – a book on human error aimed at the pop science market.

At first glance it seems to tick all the boxes, too – talking about lapses of memory, optical illusions, and even medical errors that were down to equipment design. All very relevant to ergonomics. But hold on – did that word actually appear anywhere in the book?

It certainly didn’t appear in the review, and the more I read, the more it irked me. This really is a book about ergonomics, but there is no reference to the underlying scientific discipline anywhere. The book (or the review, at least) actually has it wrong in places too – referring to the phenomenon of ‘change blindness’ (not by name, of course) as an ophthalmological problem – but it’s actually about information processing and expectations, nothing to do with our visual acuity. And there are even some areas where it’s treading on thin ice – for instance, the author’s own claim that it’s a “field guide to human error” … well, I’m afraid Sidney Dekker wrote the Field Guide to Human Error, and he’s a proper ergonomist.

The icing on the cake was when I read the plans for the UK release (later this year) to be titled ‘Errornomics’ (cashing in on the success of ‘Freakonomics’). But for a consonant or two, he so nearly stumbled across the right word!

I’ll probably end up giving it a read when it comes out in the UK, though I’m quite prepared to get wound up reading it (not least for the fact it’ll be a case of “why didn’t I do that”). I’m all for bringing this subject into the public consciousness, but I’d rather the source material were acknowledged. Could’ve been a chance to make ‘ergonomics’ a household word – alas, I fear the chance has been missed.

Ergonomically Designed!

Thursday, February 19th, 2009

The title says it all for the point of this post – the use of the phrase ‘ergonomically designed’ in adverts. It’s one of my big bugbears, and I’m sure it’ll crop up time and again in this blog. Typically associated with consumer products, what we usually find is that it’s got a rubberised grip or somesuch, but more often than not you could put safe money on there never having been an ergonomist within a hundred yards of it.

But if I’m taking issue over whether there’s been any ‘proper’ ergonomics on the product, I should say what it means to be ‘properly’ ergonomically designed. Really, it can be anything from a relatively small focus group or user testing trials, right the way through to structured scientific studies and full-on analyses. It all depends on the context (you might not want to spend a huge amount of money and time on a tape measure, but if it’s a complex safety-critical system you’ll probably be more inclined to invest in it), the key point being that it has been designed with users, or with users in mind.

The latest one I’ve seen is the JML ‘Ped-egg’, essentially a cheese grater but for getting dead skin off your feet (charming, of course). Halfway through the TV ad (which streams on their website) they show off how it’s ‘ergonomically designed’, with someone showcasing how it fits in their hand (ironically, their hand actually looks rather big for it).

Now, before the JML legal eagles come down on me, or I unknowingly upset the chief ergonomist at JML, I’m not necessarily saying this is a false claim – they may well have done some ‘proper’ ergonomics on it (make your own mind up). But, to step away from the Ped-egg and return to the general case, there are two things going on with this kind of advert. First, there’s the potential abuse of the term – it’s like ‘knock-off ergonomics’. That’s not just us being precious as ergonomists – it’s the kind of thing that can give the whole field a bad name, if such an ‘ergonomically designed’ product ends up giving someone RSI or something. All our hard work to convince people of the cost-benefit equation in ergonomics down the drain.

But on the other hand, there’s something of a silver lining here. For manufacturers to be making these claims in such a high-profile way suggests that they see it as adding value to their product. Ergonomics as a marketing tool – fancy that! Naturally I’m biased, but I think that should be the case for anything. Ergonomics should add value, and it should be a selling point – but only if it’s done properly.

Ergonomics Can (and Should) Be Fun!

MPG Feedback Data on a Honda from humanfactorsblog.org

This great article http://www.humanfactorsblog.org/2008/11/26/interface-aid-for-hyper-milers/ from www.humanfactorsblog.org reminded us of another EPSRC funded project ‘Footlite‘ that colleagues and some of the Real World Design team are working on.

Both this dashboard ‘widget’ from Honda and one aspect of the Footlite project are working on eliciting a more economical driving style from the user of the vehicle. It would have been too easy for this to have been presented in a lecturing and instructive manner and for the user to feel restricted in their enjoyment of driving. 

Instead, the more economically you drive the more you little seedling grows into a tree throughout the course of your journey, effectively presenting the concept of driving economically in an intrinsically motivating manner.

This is also similar in style to another Japanese ‘innovation/fad’ a few years back of Tamagotchis a virtual pet that children (and adults) could nurture in a similarly engaging and intrinsically motivating manner.

Are there any other situations where manufacturers have (or should) take inspiration from toys or computer game companies to make products more engaging?

“Bad design means that ergonomics and functions were not given high enough priority”

Monday, November 17th, 2008

This statement from Ergonomics In The News quoting German Industrial Designer Peter Knopp understandably attracted our attention, as much for how he represents his view of the relationship between design and ergonomics as for what he actually says about that relationship.

We’d like to share Peter’s sentiment by rephrasing it more positively: “Ergonomics prevents bad design and poor functionality.” Because as we all know, and as the old cliche goes, prevention is better than cure!

Unfortunately, as this article reveals, often Ergonomics is often only integrated into the Design Process as a ‘cure’ for poorly considered human interaction as opposed to acting as the starting point in a genuinely human centred design process.  

“Design should make technology understandable and accessible. It should ensure that people can make use of devices.” Gerd E. Wilsdorf, chief designer for Siemens Electronic Devices in Munich.

It is Ergonomics that will enable Design and Designers to do this.

What do you think? What does Ergonomics mean to you? Do you have any examples of products where the designer has not made technology accessible to you? Use the comments link on this post to let us know and we could feature your story in an exhibition at The Design Museum in London in a year’s time.
