BBC Four: The Beauty of Diagrams and The Joy of Stats


BBC Four has been showing a great series over the past few weeks called The Beauty of Diagrams. The first three parts have looked at Da Vinci’s Vetruvian Man, Copernicus’s depiction of the solar system, and Newton’s prism. The next episode looks at Florence Nightingale.

Nightingale is a figure every British schoolchild probably gets taught about, but not for her ability to depict complex statistics graphically:

Can a diagram save lives? Florence Nightingale is best known as the Lady of the Lamp, who cared for thousands of soldiers in appalling conditions during the Crimean War of 1854-6. What is less well-known is that she was a superb statistician, and the first to use a statistical graphic as a call to action.

After the war, Nightingale wrote a passionate report on why the soldiers had died in such large numbers and it revealed the astonishing fact that out of 18,000 deaths, 16,000 had been due to infectious diseases in hospital rather than battle wounds. The report included her revolutionary and controversial ‘Rose Diagram’, whose message was potent and direct – hospitals can kill. The diagram was designed to persuade the British government that, if sanitation in hospitals was improved, many deaths could be avoided. Nightingale’s pioneering diagram was a catalyst in the creation of better and cleaner hospitals that would go on to save thousands of lives.

Meanwhile, another programme looks at “The Joy of Stats” – yes joy.

Infographics are hot topics at the moment and sites like Information Aesthetics and Visual Complexity present a wide variety of ways to illustrate often complex concepts. Sometimes the “cleverness” can get in the way of the story. But designers and illustrators have a huge role to play in helping people access the true meaning of the deluge of data we’re bombarded with every day.

In the first part, Hans Rosling, who has become something of an internet sensation thanks to his TED talk on data visualisation and storytelling, hows why stats aren’t boring. The full first episode is below while it’s available, but here’s a clip to be going on with:

Both series are well worth watching while they’re available on iPlayer and at the time of writing can be seen on Wednesdays (Stats) and Thursdays (Diagrams) with various repeats throughout the week.

Information Design on Newsnight. Shame it turned in to a fight…

Information graphics got a rare primetime outing when Newsnight discussed David McCandless’s book Information is Beautiful. You can watch the fight discussion on iPlayer for the next few days.

Sadly the event turned in to something of an argument between McCandless (argument: presenting information in a beautiful way can help people absorb it better) and Neville Brody (argument: it makes you miss the core message).

I’m not sure why Brody took that line. It’s a shame that design can’t be discussed on a serious news programme without people playing to stereotypes of what graphic designers are like.

I also wonder why Brody was picked rather than, say, a statistician or a journalist – they’d be better critics of infographics at their best and worst.

Anyway, some people clearly loved it. Design Week’s blog gives the bout to Brody while at the same time seeming to back McCandless’s position:

With an endless flood of data and stats coursing through the Internet and other media, infographics are becoming invaluable.

As Alex Morrison, managing director of Cogapp, said in  Design Week last month, ‘We’re entering a new world where events, locations and contextual information are open and shared, and it’s going to be huge. Visualisation is the sexy graphics output of that, but the challenge will be in designing information architecture which makes sense of it and allows people to do something useful with it.’

Think statistics are boring? Think again…

You can prove pretty much anything with statistics, but one of the problems with all those numbers, percentages, quartiles and so on is that they don’t look very interesting.

Take a look at this short talk by Hans Rosling where he uses interactive graphics to debunk some myths about the developing world.

Making sense of news in the information age

Roy Greenslade at The Guardian offers some select quotes from a recent report from the Columbia Journalism Review on the future of news organisations. They present some interesting perspectives on the amount of information we’re given these days, how we handle it, and value it, and how traditional media publishers respond.

“The information age is defined by output: we produce far more information than we can possibly manage, let alone absorb. Before the digital era, information was limited by our means to contain it.

“Publishing was restricted by paper and delivery costs; broadcasting was circumscribed by available frequencies and airtime. The internet, on the other hand, has unlimited capacity at near-zero cost.

“There are more than 70m blogs and 150m web sites today — a number that is expanding at a rate of approximately 10,000 an hour. Two hundred and ten billion e-mails are sent each day… Pick your metaphor: we’re drowning, buried, snowed under.”

The result? Newspapers have indulged in cost-cutting in order to try to preserve profitability. But news is available for free.

“News is part of the atmosphere now… It finds us in airport lounges and taxicabs, on our smart phones and PDAs, through e-mail providers and internet search engines. Much of the time, it arrives unpackaged: headlines, updates, and articles are snatched from their original sources…

“News comes at us in a flood of unrelated snippets… But information without context is meaningless. It is incapable of informing and can make consumers feel lost.”

“In their struggle to find a financial foothold, they have neglected to look hard enough at the larger implications of the new information landscape — and more generally, of modern life.

“How do people process information? How has media saturation affected news consumption? What must the news media do in order to fulfill their critical role of informing the public, as well as survive?

“If they were to address these questions head on, many news outlets would discover that their actions thus far — to increase the volume and frequency of production, sometimes frantically and mindlessly—have only made things more difficult for the consumer.”

Why is public signage failing? – Design Week

Interesting article from Design Week:

The phrase ‘to have lost one’s way’ is often applied to people who have become anxious, confused and vulnerable. Although meant metaphorically, it’s no coincidence that to literally lose one’s way – to become disoriented – also causes tension to rise very quickly. In public spaces, such as hospitals, car parks and stations, this is the last thing users want, yet poorly designed wayfinding systems often compromise safety and may even increase the risks of criminal behaviour.
Blind alleys, dead ends, poor sight lines and disappearing trails all leave people floundering. As the Home Office’s guide to designing out crime says, good street lighting and wayfinding measures, clear sight lines and a minimum of secluded or isolated areas go a long way towards making people and places less vulnerable.

‘In designing spaces we want people to feel safer and be safer, and wayfinding is important in this,’ says Jake Desyllas, director of wayfinding and pedestrian movement specialist Intelligent Space. ‘By moving people around in a certain way, you can increase the number of people who are viewing a space, as well as the potential for people to enter it at any given moment. Even if no one is actually coming in through a doorway, the fact that they might makes a space feel safer than, say, an alleyway which nobody can suddenly enter.’ The need for a calm, safe flow of people is especially important in environments where tension may already be high, such as hospitals.

At Birmingham Heartlands Hospital, for example, the Accident & Emergency department suffered a rise in crime five years ago, especially in violence towards staff. An analysis by Intelligent Space found that incidents were talking place in the treatment rooms – the worst possible place – largely because people entered through the wrong entrance and were then drawn by natural light and activity into a medicallooking area. Poor wayfinding and signage also led to rising stress levels, increasing the likelihood of aggression. Intelligent Space created a new wayfinding system and resited the reception area so that it provides greater ‘natural surveillance’ by staff; the number of incidents subsequently fell by around 80 per cent.

Car parks are another trouble spot…

MindNode – Free mind mapping for Leopard

2BEA4F5E-5CF7-4045-8A5F-449C1DE79C37.jpg

A new, free, Mindmapping application!

MindNode is a free Leopard-only mind mapping application from Markus Müller, based in Austria. The application is by no means feature-rich; in fact, it’s so simple as to be a bit disarming at first. But what it lacks in features, it makes up for in elegance.

The interface is incredibly clean. To create a new node, simply double-click anywhere on the window, or press the Tab key when focused on a node to create a new child node. To create a node at the same level as the one that is currently in focus, press option-Tab.

As new nodes are added at the same level, they surround the previous nodes. For example, the second new node appears below the original one. The third appears above. Below, above, below, above. While this is an easy way to keep everything grouped together, it’s not particularly useful if you’re using MindNode to create a list with any sort of ordering. Some would argue that mind maps should not worry about ordering since it should be all about capturing ideas. But given that mind maps are useful in large part because they allow for graphical organization, this behavior is a bit unfortunate.

Other than that one small beef, MindNode is a nice, small, but useful tool that will be right at home in your Applications folder for the next time you find yourself needing to do some brainstorming.

Captioning Sucks!

The Open & Closed Project, which focuses on accessible media, turns its sights on captioning on TV and DVD:

Not enough of it!

Broadcasters, movie studios, and pretty much everybody else have spent 30 years cooking up one excuse after another not to caption their programming. And it’s happening all over again online.

They don’t listen!

You can complain all you want, but does anything ever get better?

It’s hard to read!

If you’ve ever had trouble just reading captions (especially on DVD), it’s probably not your fault. The fonts suck.

What makes a good airport?

BBC News Magazine reports:

23D1850B-E009-4A9E-A61E-4000633AA7D1.jpg

After 20 years trying to get off the runway, Heathrow’s Terminal 5 is about to open and promises a better experience for passengers. But what kind of features can make catching a plane less of a headache?
Flying is an inherently stressful experience. There’s the waiting, the queuing, the crowds, the luggage and the wandering kids, even before the butterflies in the stomach at take-off.

Most of these irritations are beyond the control of the passenger and, unlike the bus or the train, flying is a mode of transport that global travellers can’t really avoid.

Increased security measures in 2006 compounded these woes and the sight of queues snaking outside terminal buildings at Heathrow underlined its reputation as a difficult place to begin a holiday.
Terminal 5, which is officially opened on Friday, will go some way to addressing that – and at £4.3bn and 20 years in the planning you would expect it to.

But these are not problems unique to Heathrow. So what makes a good airport? Here are five key features:

SIGNAGE

Orientation is always among the top demands by customers, says Paul Mijksenaar, whose company by the same name has designed the signs for airports in Amsterdam, Frankfurt and Athens.
‘The first requirement is reliability, that once you are looking for something that you find it on a sign close by and you are sure it will direct you all the way to reach your destination. A lot of sign systems are not good and sometimes the trail is lost and it stops.’

Charles De Gaulle airport is particularly bad, he says, because it uses too many figures and jargon.

There are so many services in airports that it’s difficult to direct people to everything, so it’s best to point out ‘clusters’ like a food court or shops.

Colour coding saves reading time by a third, he says. It’s common to use black text on yellow background for flying information (departures, arrivals), yellow text on black for bathroom facilities, green for exits and blue for food and retail.
‘Passengers don’t even realise it. People use a system like that but an hour afterwards, you can ask them and they have no idea. It’s very intuitive.’

Pictograms should only be used for services easily imaged like taxis and phones and all signs at one airport should use just one font (his favourite is Gill sans serif).

‘What would be fantastic for a passenger is to fly from London to, say, Hong Kong, and you find the same pictograms, colour coding and nomenclature.

‘It helps enormously and makes you feel at home. Airports like to be different but airport signage is not the tool to be different, it should be in harmony.’

Tell that to the architects, who commonly prefer signs to be discreetly placed and understated.

BUILDING DESIGN

An architect’s key aim is trying to reduce passenger stress, says Simon Smithson of Rogers, Stirk Harbour and Partners.

He was project architect of the new terminal at Barajas in Madrid, which won the architectural Oscar, the Stirling Prize, and he thinks a building’s design can go a long way to easing traveller tensions.

‘The most obvious is being able to understand how the building is organised. Some of the worst cases like Gatwick or Schiphol, you enter the building and you have no idea what your route is.’
Out with corridors and enclosed areas, in with space, daylight and views.

Barajas has a high, wavy roof that makes the space feel airy and unconstrained, he says, and the roof almost floats, as if looking at the water surface while snorkelling. The glass walls are like ‘great big curtains’ and give views of the planes outside.

Airports are the new plazas, the new town squares, he says, and should try to be a public space rather than a building.

‘The visual and acoustic onslaught of advertising spaces and announcements is very wearing.

‘Your foreground is a riot of information and conflicting objectives – ‘Buy, buy, sell, sell, go here, go there’.

‘As architects we recognise that we have little control over that foreground but we have control over the container.’

Travel editor of the Independent, Simon Calder, picks Marseille’s budget ‘mp2′ airport as a model of simplicity.
‘Flying is a simple pleasure instead of the ghastly experience it is at Gatwick and Heathrow.

‘Marseilles is industrial-feeling in design, bare concrete and steel, nothing extra. It’s extremely efficient and a model of airport design, unlike Terminal 5, which is all very well but I can think of better ways to spend £4.5bn.’

TRANSPORT LINKS

No matter how snazzy an airport building, a fraught journey getting there will put passengers in a dark mood.

The luxury and speed of the Heathrow Express, for example, comes at a high price (£15) compared to the often overcrowded Tube.
Driving to Terminal 4 can be stressful too, says Mr Smithson. But Terminal 5, with which he was once involved, is a huge improvement and recognises that airports are major transport hubs.

‘The forecourt connection between air side and land side modes of transport – the space in front of the building – is most innovative.

‘If you come out of an airport you can feel you are nowhere but you exit there and feel you are in a street space. It is setting a precedent.’

That’s great if you want to get a taxi, but it’s still the slow and crowded Piccadilly line for people who need the Tube.

Fewer problems at Birmingham, where the long-term car park is a short walk from the terminal building.

Or at Hong Kong, where the Airport Express train takes passengers from downtown into the heart of the airport in 20 minutes.

NO QUEUES

There are lines for check-in, then passport check, then security, then the gate, then your seat on the aircraft and then baggage reclaim and immigration at the other end.

It’s not all the fault of the airport or airline – the Immigration Service and the government rules on security play their part, says Rod Fewings, who lectures in airport design at Cranfield University. But Birmingham can offer lessons in how it’s done.
‘Birmingham security is very quick and efficient. The airport has expanded its terminal building piecemeal but they seem to have got the balance right and baggage reclaim is pretty quick.’

Other top performers, he says, include Munich, Helsinki and Luton.

Online and self-service check-in is becoming more common to speed things up, and there are plenty of kiosks at T5 for this purpose, he says. But it’s no good if the bag drop-off is under-staffed, as it was once in his experience at Madrid.

The processing of people may be beyond the control of architects but a good design can ease the trauma of queuing, says Mr Smithson.

‘The actual function of the building and the perception of the passengers is to some degree out of our hands but the quality of the space in which we are waiting – the views, the acoustics and daylighting – can make an experience either good or bad.

‘Ten minutes in a horrible space can feel like half an hour but in a nice space can pass relatively fast.’

RETAIL

Air passengers need to be entertained and ever since Shannon, Ireland’s second airport, opened the world’s first duty-free shop in 1947, retail has become a big earner for airport authorities.

This week Ferrovial, which owns BAA, sold its World Duty Free shops to Italy’s Autogrill for £546.6m ($1.10bn), partly to pay off Ferrovial’s debts.
Shopping is now fundamental to the passenger experience, says Robbie Gill, managing director of The Design Solution and an expert on retail architecture.

‘The danger is that too many airports are beginning to look the same and the challenge for the smartest airports is to integrate with local flair the well-known national brands and the international powerhouses.’

This is something that Rome Fiumicino and Barcelona demonstrate well, he says.

But there is an ongoing tension between retail planners and architects, he says, because the latter treat the commercial activities as very much secondary to the ‘architectural dream’.

No passengers like to feel overwhelmed or pressured into buying, says Mr Smithson, and one way Barajas tries to avoid this ‘invasion of space’ is by maintaining outside views.”

Apple’s design process

Business Week on Apple’s design process:

Interesting presentation at SXSW from Michael Lopp, senior engineering manager at Apple, who tried to assess how Apple can ‘get’ design when so many other companies try and fail. After describing Apple’s process of delivering consumers with a succession of presents (‘really good ideas wrapped up in other really good ideas’ — in other words, great software in fabulous hardware in beautiful packaging), he asked the question many have asked in their time: ‘How the f*ck do you do that?’ (South by Southwest is at ease with its panelists speaking earthily.) Then he went into a few details:

Pixel Perfect Mockups

This, Lopp admitted, causes a huge amount of work and takes an enormous amount of time. But, he added, ‘it removes all ambiguity.’ That might add time up front, but it removes the need to correct mistakes later on.

10 to 3 to 1

Apple designers come up with 10 entirely different mock ups of any new feature. Not, Lopp said, ‘seven in order to make three look good’, which seems to be a fairly standard practice elsewhere. They’ll take ten, and give themselves room to design without restriction. Later they whittle that number to three, spend more months on those three and then finally end up with one strong decision.

Paired Design Meetings

This was really interesting. Every week, the teams have two meetings. One in which to brainstorm, to forget about constraints and think freely. As Lopp put it: to ‘go crazy’. Then they also hold a production meeting, an entirely separate but equally regular meeting which is the other’s antithesis. Here, the designers and engineers are required to nail everything down, to work out how this crazy idea might actually work. This process and organization continues throughout the development of any app, though of course the balance shifts as the app progresses. But keeping an option for creative thought even at a late stage is really smart.

Pony Meeting

This refers to a story Lopp told earlier in the session, in which he described the process of a senior manager outlining what they wanted from any new application: ‘I want WYSIWYG… I want it to support major browsers… I want it to reflect the spirit of the company.’ Or, as Lopp put it: ‘I want a pony!’ He added: ‘Who doesn’t? A pony is gorgeous!’ The problem, he said, is that these people are describing what they think they want. And even if they’re misguided, they, as the ones signing the checks, really cannot be ignored.

The solution, he described, is to take the best ideas from the paired design meetings and present those to leadership, who might just decide that some of those ideas are, in fact, their longed-for ponies. In this way, the ponies morph into deliverables. And the C-suite, who are quite reasonable in wanting to know what designers are up to, and absolutely entitled to want to have a say in what’s going on, are involved and included. And that helps to ensure that there are no nasty mistakes down the line.
