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.

Distracted drivers

Something I’ve been meaning to post on since I saw it a month ago, is a story on ergoweb with a new perspective on the perennial problem of driver distractions from mobile phones. As the article comments, and as I’ve mentioned here a few times before, the fact that mobile phones are distracting is nothing new to ergonomists. But this new research from Liberty Mutual suggests that drivers aren’t aware of how much they’re being distracted.

I think this is interesting from a number of perspectives. There’s all the deep psychological stuff, such as the interaction between mental workload and situation awareness (that is, the fact that they’re loaded with a distracting task possibly affects their own self-awareness of their performance, let alone awareness of the road situation). And there’s the practical implications, like how drivers will be more willing to engage in these activities if they don’t see them as a problem – also relevant to drink, drugs, fatigue, and any number of driver impairments.

The story focuses on in-car distractions, but it’s also piqued my interest in outside distractions to – relevant to a study I conducted on roadside advertising in our driving simulator at Brunel, which has just been published in Transportation Research Part F. I was stunned by the impact this study had with people on both sides of the argument – safety campaigners and advertising professionals alike – and the preliminary report I produced has been widely circulated while the paper was in the publication process. In fact, the advertising industry commissioned an “independent” report specifically to discredit my report, which mainly criticised the study on the grounds it hadn’t been peer-reviewed (which it has now) and that it was conducted in a simulator (which I defended in the paper). I should probably be upset that they commissioned this report, but it’s actually faintly amusing that they took the study so seriously.

Anyway, I see a clear link from this to the Liberty Mutual findings about awareness of distractions. Advertising, by its nature, is designed to attract attention – almost without us knowing it, otherwise it hasn’t done its job. So it’s a double-whammy if drivers are unwillingly being distracted, and then being unaware of how that’s affected their driving. But it’s not just that – if there’s an intuitive belief that distractions such as advertising don’t seem so bad, then it means there’s an even more pressing need for hard quantitative data to close the case.

Cheltenham Festival of Science

No prizes for guessing what this post is about – last week we took a sample of the Real World Design exhibition to the Cheltenham Festival of Science as a sneak preview for them and a test run for us. Needless to say, this was a fantastic opportunity, afforded to us by some great work in the Ergonomics Society office, which we grabbed with both hands.

Cheltenham is one of the biggest science festivals in the UK, and always attracts some star names – we caught a glimpse of Robert Winston floating about; also in attendance and giving lectures were the likes of Richard Hammond, Carol Vorderman, and Alice Roberts (though I'm personally disappointed I didn't bump into her).

The preview exhibit we took was related to the ergonomics of the Sky TV remote control, which is the most advanced piece of work we currently have on the exhibition project. Fergus Bisset, the design researcher on the project, did a stellar job of putting together an innovative stand at short notice, complete with interactive elements. Fergus also carried the can for the whole duration of the festival, assisted on different days by staff and members of the Ergonomics Society, who kindly gave up their time to help out (pictured right is Dave O’Neill, Chief Executive of the Ergonomics Society). Our thanks go out to all, it was an enormous help and above and beyond the call of duty.

All in all I think we can say it was a successful week – just getting the exhibit into Cheltenham was an achievement in itself! But we also had a lot of interest from children and adults alike, helped no end by being on the EPSRC’s ‘Impact Trail’, so the children were encouraged to come and see us for an answer in their question booklet. It’s also been a learning experience in taking things forward to the big exhibition in November – which I know will come round sooner than we think.

A grand opening

It must be the season for events, as hot on the heels of the Ergonomics Society Anniversary Conference last week, this week it was Brunel University’s turn to steal a little limelight with a major event for the official opening of the Michael Sterling building.

Professor Michael Sterling is a former Vice-Chancellor of Brunel, and having just retired he was the honoured guest at the event. The Michael Sterling building provides extra teaching, research and lab space for the School of Engineering and Design, and is a very modern building with some attractive spaces.

We were privileged in the Human-Centred Design Institute to play our part at the event, starting from the off as Fergus Bisset, who is working with me on the Real World Design exhibition, eloquently opened the proceedings – complete with kilt and all. After the formalities and a buffet lunch, there was a series of seminars showcasing the different research groupings in the School. Dr Hua Dong, Prof Joseph Giacomin and myself gave part of the Design & Manufacture seminar to highlight our work in the HCDI.

All in all we hope it was a positive and beneficial event for our external visitors, but it was even a good chance to catch up on the research activities of our own colleagues in the School – something we don’t get a chance to do often enough. One project which caught my eye was the Brunel X-team electric motorbike, being entered in the Isle of Man TTXGP on June 12th. I’m looking forward to watching that on telly – and only wish we could’ve done something on the human-centred design aspects of the bike!

Ergonomics Society Anniversary Conference

The highlight of this week has to be the Ergonomics Society 60th Anniversary Conference, held Wednesday and Thursday at the Royal College of Physicians just by The Regent’s Park in London.

Actually the festivities kicked off on Tuesday evening with a VIP reception, where we were showered with wine and nibbles and treated to a couple of top drawer speeches from Dr Ian Gibson, MP for Norwich North, and Professor Pieter Rookmaaker, President of the Federation of European Ergonomics Societies (FEES). Dr Gibson’s speech was particularly encouraging, being a member of the Innovation Universities and Skills Committee and someone who’s especially sympathetic to the ergonomics cause. Prof Rookmaaker also drew our attention to the first European Ergonomics conference to be held in Bruges from 10th October 2010 – surely a must-attend event.

Wednesday and Thursday were the main session days, where there were several plenary papers given by esteemed ergonomists from around the world, plus a bunch of interesting sessions on topics from public health, through human factors integration, to accidents and human error.

I teamed up with Prof Jan Noyes from Bristol and Dr Sarah Sharples from Nottingham to give a session on automation, which proved intimidatingly popular with standing room only at the back. One of those where you deliberately avoid looking at the audience for fear you’ll get stage fright. I also chaired a session on road ergonomics with papers from Dr Alex Stedmon (also at Nottingham), Nick Gkikas from Loughborough, and Dr Sandy Robertson of UCL.

Fergus Bisset (who was Twittering away during the conference) and I had a stand promoting the Real World Design exhibition at the Design Museum (see my blogpost here for more), which attracted good attention from the delegates and gave us some more ideas for exhibits in the medical and consumer product areas.

Socially it was great as well, always a good opportunity to catch up with old networks and make new ones, with a very posh dinner on Wednesday night courtesy of our hosts at the RCP. And let’s not forget the location – a glorious part of London, so quiet and leafy that you could easily forget you’re actually in the capital. The RCP itself was an excellent venue, especially the Dorchester Library where the VIP reception was held.

Next year’s conference reverts to the more traditional format – this one was special for the anniversary – and will be at Keele University in Staffordshire. Hopefully see you there!

Human-centred driving

One of my main areas of research is in transport ergonomics - planes, trains and automobiles all interest me, though it's fair to say that cars have featured most strongly in my research history. We're currently working on a project called 'Foot-LITE' at Brunel, as part of a much wider consortium involving universities and industry partners.

Foot-LITE is aimed at encouraging safer and 'greener' driving, by monitoring your driving performance and giving you feedback on how you're doing - both in the car and afterwards using a web-based interface. Our role at Brunel is mainly to cover the ergonomics of the interface design - making sure it's usable to promote the desired behaviours while not introducing distraction or other undesired effects. We're about to embark on a series of experiments in the Brunel University Driving Simulator over the coming months to test the prototypes we've developed.

Whilst I don't think our project partners would argue that we're the designated ergonomists on the team, in many ways I see the whole project concept as an embodiment of the human-centred design philosophy. It's a response to a distinct and contemporary set of user needs (safety and environmental impact) but doesn't impose any kind of authority over the driver - it's purely an advisor, acting like a co-driver or assistant. So it's very much a voluntary service, as opposed to some levels of technology or automation that purport to take over control from the human - which isn't very human-centred.

On another level, Foot-LITE represents a foray into the world of environmentalism - largely untrodden ground for ergonomics and human-centred design, which has traditionally been associated with safety, efficiency and satisfaction. As we look to the future challenges for this field, I'm of the mind that we can't ignore the environmental agenda. More to the point, being a behavioural issue, we can use persuasive technology (as Dan Lockton does) to encourage behavioural changes in just the way Foot-LITE seeks to achieve. Climate change is therefore another area that human-centred designers can - and probably should - firmly do something about.

Human-centred design

I’ll be honest right from the off - I'm a newbie. This is my first blog, and this is my first post. My plan for this blog is to share and air my views on human-centred design (HCD; aka ergonomics, aka human factors - semantic differences but essentially we’re all on the same side, and I use these terms interchangeably). My motivation is that I believe HCD matters - not just to my colleagues and me, but to everyone.

We all come across ergonomics every day, at home, at work, and at leisure. Consumer products, transport, workstations - any time we interact with, well, anything that’s been designed. But most of the time you probably don’t notice it - except when ergonomics goes bad, when it’s right in your face, causing errors and frustration.

Sticking with the honesty, I’ll come clean and say I’m not a designer. My background is in psychology, and I got into this by applying my knowledge of what people can and can’t do to their performance in complex systems (transport - driver/pilot performance, in my case). But through my career I’ve come round to the idea that the people best placed to make a difference here are those who put the products and systems out into the real world - the designers and engineers. That’s why at Brunel University we’re training the next generation of human-centred designers.

Over the course of this blog I’d like to share our achievements at Brunel, as well as my own personal encounters with HCD in everyday life. I hope you find it useful as well as stimulating to think about your own experiences of HCD - good or bad.
