Texting while driving

Okay, so I'm catching up on stuff after the Christmas break, but this is one paper that's made quite a splash - I'm certainly not the first to be blogging about it.  The latest issue of the journal Human Factors features a paper by Frank Drews and colleagues which, I gather, is the first peer-reviewed study on the effects of texting on driver performance.

As you might expect, texting and driving is bad.  Worse, in fact, than talking on the phone - and we already know that's bad enough, having been equated to serious drink-driving.  Texting slows brake reactions, impairs longitudinal and lateral control, and increases crash risk.

The study has already attracted some critcism for only involving young drivers - but I'd say that if young people can't text and drive, then the effects would be worse for older drivers.  The research will, I'm sure, be done in time, and this paper will no doubt become very heavily cited.

One other implication in the media coverage which concerns me is the potential for this to drown the effects of talking on the phone while driving - some of the articles I've seen are spun to suggest that because texting is so bad, phoning isn't so bad after all.  We (as a community) need to make sure that we don't forget how bad phoning and driving is - whether handheld or hands-free.

Surprisingly, you can download this paper for free here - though how long this will be available I don't know.

Review of the decade

At the end of every year, there always seems to be a contagion of top 10 (or 100, or 1000) lists in the media reviewing the previous 12 months - usually on TV, featuring various rent-a-quote nonentities.  Naturally, at the end of 2009, there were even more of these to ensure we'd covered the last 10 years.  However, a couple of websites have caught my eye as they've been reviewing the technological progress in the 'noughties'.

I must have a short memory, as I was quite surprised to see just how many gadgets that we now take for granted are less than a decade old.  The iPod and iPhone, Freeview and flatscreen TVs, and more recently the Kindle and other e-book readers have all been born since 2000.  Perhaps with even more impact, the rise of the social web started in 2000 with the launch of Friends Reunited.

Obviously I'm interested in the human-centred design implications of such advances.  It all serves to reinforce my long-held conviction that with the world getting more technological, the implications for cognitive ergonomics are ever more significant.  I'm sure I said somewhere that the 21st century is the century of the user...

The end of the 60th

So 2009 is coming to an end, and with it I think a rather successful 60th anniversary year for the Ergonomics Society - or should I say, the Institute of Ergonomics and Human Factors (IEHF), for on 20th October the change of name was officially approved by Companies House.

Naturally I'm biased towards the exhibition at the Design Museum - which runs to 7th March 2010, so we are prolonging the celebrations a bit. Trying to be as objective as possible, 'Ergonomics: Real Design' has gone down pretty well so far. Last time I reported on the excellent media coverage at the opening and the VIP reception a few days later. Since then it has been picked up by other national and international listings (including the Wall Street Journal), and the other day I learned it was even getting exposure in New Zealand courtesy of Dave Moore of the NZ Ergonomics Society. By all accounts visitor feedback is good and footfall at the Design Museum is up, though we're in the process of conducting our formal evaluations to see just how big an impact the exhibition has had.

Next year we plan to keep the momentum going through (hopefully) touring the exhibition internationally, and an IEHF campaign to better integrate ergonomics into design process. Despite the fact that it's "just another year", I'm sure we'll be just as busy and I do, of course, plan to keep you updated here!

In the meantime, it only remains for me to wish everyone reading this, a very Merry Christmas and a happy new year.

Ergonomics: Real Design

Well, it's finally arrived - all of our hard work over the last year or so has paid off, and the Ergonomics: Real Design exhibition at London's Design Museum is now open.

There was a media preview last Tuesday, which generated us some excellent coverage on the BBC and in The Independent, as well as several popular design magazines. Then it opened to the public on Wednesday, and by all accounts the feedback is good, and people are engaging with the exhibition as we hoped.

Last night was the big fanfare though - the Ergonomics Society (now officially known as the Institute of Ergonomics and Human Factors) held a private VIP reception for over 100 people, which - in my humble opinion - went down very well indeed. There was certainly a real buzz about the place, and for me it really brought it home that the exhibition had really happened. I think until I saw people actually going round it, it hadn't quite sunk in with me. All very exciting.

I must say thanks again to everyone who pulled together to make it happen - Fergus, Gemma, Margaret, Laura, Roger, Colin, and of course Reg, who got the ball rolling in the first place and has stuck with the project all the way through. Finally, a nod to the sponsors, the EPSRC, who are evidently quite pleased with it as it's currently featuring on the front page of their website too.

Human-centred ketchup!

I just couldn't resist following up with this little tidbit I heard on the Chris Evans show on Radio 2, on the way home from my driving meeting I just blogged about. His theme for the show was red vs. brown - that is, in terms of sauces. He had a representative from Heinz giving us the history of ketchup, but the bit that pricked my ears up was his explanation of the design decision to turn the bottles upside-down. In almost his exact words, basically he said that it was designed by the people - their customers, the users. They'd observed and listened, and decided the upside-down bottle would satisfy a key user need.

Who'd have thought it? Human-centred design in action at Heinz. Marvellous.

I'm sure you can listen to the show on BBC iPlayer for a little while, but I couldn't tell you exactly when in the show this interview happened - it was definitely in the first hour, but I was too busy watching the road rather than watching the clock, of course.

New cars, new toys

I’ve been playing with new cars again today – one of the few perks of the job which crop up from time to time. I can’t give too much away as it was a closed meeting, but most of the cars and their associated technologies are already on the market so I can talk in general terms. Suffice to say I got to drive several cars much more valuable than my own (some would even pay off my mortgage…), and each jam-packed with active safety gadgets. In fact, that was one of my first observations – the sheer amount of technology and computing power now being rammed into cars, with radars, cameras and sensors literally everywhere.

Anyway, that’s not what I really wanted to talk about. I’ve aired my thoughts about vehicle automation before on this blog, so I won’t go over old ground, but there was a couple of new observations I wanted to pick up on.

One or two of the vehicle manufacturers are using speed sign recognition cameras, sometimes coupled with a GPS map database, to display current speed limit information inside the car. I can only think this is a Good Thing – I don’t have evidence, but to my mind many speeding offences aren’t for lack of restraint, rather are to do with drivers missing or forgetting the last sign they passed. Sometimes the road environment even tries to trip us up, with outdated laws preventing the use of repeater signs for 30mph limits, for instance. I for one would really like one of these cars with a speed limit aide-memoire, and would much prefer that over an ISA system which just stops me from speeding. Don’t get me wrong – I’m not a speeder, it just makes me uncomfortable to take control from the driver in that way. And this is a personal and professional opinion, as I’ve written about in this paper.

Which brings me onto my next point – who’s in charge? The same paper talks about philosophies of ‘hard’ vs. ‘soft’ automation – basically regarding who has the last power of veto, the computer (hard) or the human (soft). We’ve seen aircraft manufacturers take different approaches based on these philosophies, and it’s now fascinating to see vehicle manufacturers doing the same thing. My view is the same as it’s always been – we should support drivers, not replace them. But I qualify that in the paper by talking about ‘below the line’ vehicle operations (such as ABS, ESC – and I could now include last-minute collision mitigation in that) which can be automated since they don’t consciously affect the driver’s task.

It seems that many of these technologies are going down well with the customers. My concern is whether that translates into better (safer) driving (for which we don’t have the data yet), and if there are any longer-term behavioural compensations that might cancel out any beneficial effects.

One thing I certainly didn’t expect from the day, though, was for the cars to be groping me – one of them had a seat massager (for passengers), while another had a ‘dynamic seat bolster’ to stop you sliding about in corners. Definitely a new experience for me…

Ghosts of transport yet to come

I had the privilege this week of presenting at the Parliamentary Advisory Council for Transport Safety's (PACTS) conference on 'Beyond 2010: the challenges ahead'. This was largely centred around the proposed road safety strategy for the future (which I've commented on before) and had a very much 'what are we going to do about it' feel. Interestingly, the opening sessions were largely focused on the environmental aspects of driving and promotion of eco-driving, as opposed to safe driving. I found this surprising given the context, but perhaps represents a shift in emphasis for transport policy. Naturally I was banging the drum for human-centred design and how it can solve all our problems for safe and eco-driving in the future. Simple as that.

One of the most memorable presentations from the day was the last one (probably a recency effect...) from ACPO's Mick Giannasi, talking in part about Gwent Police's recent campaign on texting and driving. The 'Cow' video has made it around the world already and has had some ten million hits apparently, even though it was only supposed to be a local thing and was done on a budget of about £10k. (Excerpts are on YouTube - link above - though you have to log in as it's deemed to be graphic material.) This is just amazing impact from both road safety and public engagement perspectives. Mick also showed evidence of how it's already working locally, with its first screening at an event for young drivers in South Wales - cameras were trained on the crowd to record reactions, and interviews afterwards showed the effect it had on those present. It really is hard-hitting.

After the PACTS conference I went straight to Imperial College for the Lloyd's Register Educational Trust's Annual Lecture in Transport Risk Management. Gretchen Burrett, Director of Safety at National Air Traffic Services (NATS), talked about human factors in aviation and air traffic control. She gave a really splendid exposition of the benefits of human factors in safety-critical systems. One of the stand-out points for me was how they're actually recording positive changes in behaviour as markers of effectiveness for HF in the cost-benefit analysis - that's as opposed to just monitoring reductions in errors or accidents. I was really impressed with this approach - I've long thought that one of our biggest barriers in uptake of HF is persuading people of the benefits. Since nobody notices the absence of accidents, people like Gretchen are otherwise the unsung heroes of safety. Measuring positive changes that people will actually notice is a great way for HF to hammer home its message.

Distracted and inattentive

Last week I attended the First International Conference on Driver Distraction and Inattention, held at Lindholmen Science Park in Gothenburg. The site is next door to Chalmers University, which itself has good links with Volvo research – so it was an excellent choice of venue, and as you can see from the pictures, a very pleasant setting to boot.

The conference itself was top notch too, with some high profile speakers and delegates, and a programme jam-packed with interesting papers for people of our ilk. In fact, there were often too many to choose from, with three parallel sessions meaning I missed a lot of stuff I wanted to see – and the proceedings aren’t going to be out for a few months either. But I’d rather have too much choice than too little – sign of a good conference for me.

We were well represented for the HCDI at Brunel – Stewart Birrell presented a paper on our Foot-LITE project, while I got involved with a symposium on roadside advertising. This is still a very hot topic, and quite timely for me as my paper has just been published in Transportation Research Part F.

The ever-ebullient Peter Hancock gave a philosophical perspective to open the conference, arguing that it is perhaps driving which forms the distraction from life, rather than life being a distraction from driving, and how the different roles we play in life can affect our role as ‘driver’. Coincidentally, these kinds of thoughts are reflected in a recent post by Tom Vanderbilt as well. I like the notion of driving being a distraction from life – it accords with what a lot of people argue about life being too busy and everyone being time-poor these days (which brings us full circle with the ‘need’ for the car to be a mobile office). However, I’m not sure where it gets us in terms of solving the problem – however you view driving, it’s still a safety-critical task, and our job is to make it as safe as possible.

Other interesting themes emerged from the conference; as you might expect a number of papers looked at the effects of in-vehicle technology – both positive and negative – while there was also a reasonable amount of research on older drivers. Perhaps disappointingly, given the great efforts of the organisers to include inattention in the conference title, most of what I saw focused on distraction rather than its cognitive cousin.

Overall they packed an awful lot into two days that it felt like a longer conference (in a good way!) – including a great social dinner at the Universeum science centre, which was duly sold to us as having a traffic safety exhibition … and sharks.

An autopian future?

I don’t feel right snaffling someone else’s blog posts, but I just had to pick up on this gem from Tom Vanderbilt, as it’s so close to my own research interests. (Tom’s is an excellent blog for driving buffs, too, and he’s always got something interesting.)

The ‘Autonomobile’ from Mike and Maaike is a design exercise to come up with a driverless car. This kind of thing comes around from time to time, and the Autonomobile is reminiscent of Concept 2096 (not a great link, but the only one I could find with an image) – another one developed to mark 100 years of the automobile, and an early inspiration in my PhD work. Interestingly, as I remarked on Tom’s blog, these are very similar but the anticipated timeframe is coming down – by 50 years, as the Autonomobile is apparently set for 2040.

I’m less convinced. Yes, these guys are right that technically speaking, we’re not far off. In controlled, closed-loop systems it is possible – see the Heathrow Personal Rapid Transit on their website, which we’ve been looking at lately. But there’s a bunch more human factors which mean that last 20 per cent (or 10, or 5) will be the real struggle. Mainly it’s the reliability issue – until the systems become so good that we can literally sit back and read the paper, there’ll always be the expectation of a human being there to supervise and save the day. And if there’s one fundamental which has come out of all the research on automation – vehicle or otherwise – it’s that humans don’t make good supervisors. We’re meant to do, not watch.

Besides, as others have pointed out, such ‘fully automated’ cars already exist to let us work, socialise etc. during the drive – they’re called taxis. And that’s the other side of the human factors equation – the social acceptability of automated cars. For one, a lot of people drive because they enjoy it. But the harder one to crack will be trust in these systems – will people ever really let go and switch off? And what happens if(when) there’s an accident – who’s to blame?

Driving Ergonomics Special Interest Group

Yesterday I went to the inaugural meeting of the Ergonomics Society’s newest Special Interest Group (SIG) – the Driving Ergonomics SIG. This was hosted at Cranfield University, though the SIG has been set up and chaired by Nick Gkikas of Loughborough University.

There’s currently some 20-odd members in the SIG, and more than half of those turned up yesterday. It’s a really good mix of academic and industrial members too, with representatives from the likes of Jaguar, Nissan, and TRL.

The meeting had a speed-dating feel to it, with rapid fire presentations from a selection of attendees – Steve Summerskill from Loughborough, Chris Day from Nissan, me, and Nick Reed from TRL – all in less than an hour! But this was quite nice to get a sampler of the backgrounds of members. And whether by accident or design, there was good balance between physical ergonomics (Steve and Chris) and the more cognitive side (Nick and me).

It already promises to be a highly active SIG, with much discussion (at the time and afterwards via the new LinkedIn group) about the objectives of the SIG and what various members want to get out of it. We’re planning to meet quarterly, and longer-term ambitions are to have some outputs – maybe a conference session, for instance. I certainly think it’s a Good Thing, and with such an enthusiastic membership it has a lot of momentum behind it.

I’m only sorry I couldn’t get to the pub for more discussion afterwards – but then I was driving home, so couldn’t have sampled the local’s finest anyway…
