Smile, you’re on Countermanded Camera

We’ve looked before at a number of technologies and products aimed at ‘preventing’ photography and image recording in some way, from censoring photographs of ‘copyrighted content’ and banknotes, to Georgia Tech’s CCD-flooding system.

Usually these systems are about locking out the public, or removing freedoms in some way (a lot of organisations seem to fear photography), but a few ‘fightback’ devices have been produced, aiming to empower the individual against others (e.g. Hewlett-Packard’s ‘paparazzi-proof’ camera) or against authority (e.g. the Backflash system intended to render a car number plate unreadable when photographed by a speed camera). The field of sousveillance – lots of interesting articles by Régine Debatty here – is also a ‘fightback’ in a parallel vein.

Taking the fightback idea further, into the realms of everyware, Miquel Mora’s IDentity Protection System, shown last month at the RCA’s Great Exhibition (many thanks to Katrin Svabo Bech for the tip-off), aims to offer the individual a way to control how his or her image is recorded – again, Régine from We Make Money Not Art:

With IDPS (IDentity Protection System), interaction designer Miquel Mora is proposing a new way to protect our visual identity from the invasion of ubiquitous surveillance cameras. He had a heap of green stickers that could stick to your jacket. Or anywhere else. The sticker blurred your image on the video screen.

“With the IDPS project I wanted to sparkle [sic.] debate about all the issues related to identity privacy,” explains Miquel. “Make people think about how our society has become a complete surveillance machine. Our identities have already been stored as data in many servers ready to be tracked. And our self image is our last resort. So we really need tools to protect our privacy. We need tools that can allow us to hide or reveal our visual image. We must have the control over it.”

“For example in one scenario a girl is wearing a tooth jewellery with IDPS technology embedded. So when she smiles she reveals it and it triggers the camera to protect her. With IDPS users can always feel comfortable, knowing that with a simple gesture like smiling, they are in control. The IDPS technology could be embedded in all kind of items, from simple badges to clothes or jewellery. For the working prototype I’m using Processing to track the stickers and pixelate the image around when it founds one.”

While the use of stickers or similar tags (why not RFID?) which can be embedded in items such as jewellery is a very neat idea aesthetically, I am not sure what economic/legal incentive would drive CCTV operators or manufacturers to include something such as IDPS in their systems and respect the wishes of users. CCTV operators generally do not want anyone to be able to exclude him or herself from being monitored and recorded, whether that’s by wearing a hoodie or a smart black hat with maroon ribbon. Or indeed a veil of some kind.

Something which actively fought back against unwanted CCTV or other surveillance intrusion, such as reversing the Georgia Tech system in some way (e.g. detecting the CCD of a digital security camera, and sending a laser to blind it temporarily, or perhaps some kind of UV strobe) would perhaps be more likely to ‘succeed’, although I’m not sure how legal it would be. Still, with RCA-quality interaction designers homing in on these kinds of issues, I think we’re going to see some very interesting concepts and solutions in the years ahead…

West Coast code meets Far East code

Thanks to Mr Person at Text Savvy, I’ve just learned that this blog is blocked in China:




Images from the Great Firewall of China test.

I don’t know if that’s good or bad. From a censorship point of view, it’s bad, but it’s certainly interesting to be able to say that the blog’s blocked in China, even if it’s just for a rather prosaic reason (using WordPress?) as Mr Person suggests, and not the incendiary demagoguery contained within these posts and comments.

(Additionally interesting is that as the whole of danlockton.co.uk seems to be blocked, I might not have any more of my portfolio items appearing on Chinese design sites. One site even had me listed alongside Karim Rashid for a while, which was odd and flattering, perhaps, though I don’t think he’ll be losing sleep over it!)

Some links

Some links. Guess what vehicle this is.

First, an apology for anyone who’s had problems with the RSS/Atom feeds over the last month or so. I think they’re fixed now (certainly Bloglines has started picking them up again) but please let me know if you don’t read this. Oops, that won’t work… anyway:

  • ‘Gadgets as Tyrants’ by Xeni Jardin, looks at digital architectures of control in the context of the 2007 Consumer Electronics Show in Las Vegas :

    Many of the tens of thousands of products displayed last week on the Vegas expo floor, as attractive and innovative as they are, are designed to restrict our use… Even children are bothered by the increasing restrictions. One electronics show attendee told me his 12-year-old recently asked him, “Why do I have to buy my favorite game five times?” Because the company that made the game wants to profit from each device the user plays it on: Wii, Xbox, PlayStation, Game Boy or phone.

    At this year’s show, the president of the Consumer Electronics Association, Gary Shapiro, spoke up for “digital freedom,” arguing that tech companies shouldn’t need Hollywood’s permission when they design a new product.

  • The Consumerist – showing a 1981 Walmart advert for a twin cassette deck – comments that “Copying music wasn’t always so taboo”.

    I’m not sure it is now, either.

  • George Preston very kindly reminds me of the excellent Trusted Computing FAQ by Ross Anderson, a fantastic exposition of the arguments. For more on Vista’s ‘trusted’ computing issues, Peter Guttmann has some very clear explanations of how shocking far we are from anything sensible. See also Richard Stallman’s ‘Right to Read’.
  • David Rickerson equally kindly sends me details of a modern Panopticon prison recently built in Colorado – quite impressive in a way:

    …Architects hit a snag when they realized too much visibility could create problems.

    “We’ve got lots of windows looking in, but the drawback is that inmates can look from one unit to another through the windows at the central core area of the ward,” Gulliksen says. “That’s a big deal. You don’t want inmates to see other inmates across the hall with gang affiliations and things like that.”

    To minimize unwanted visibility, the design team applied a reflective film to all the windows facing the wards. Deputies can see out, but inmates cannot see in. Much like the 18th-century Panopticon, the El Paso County jail design keeps inmates from seeing who is watching them.

  • Should the iPhone be more open?

    As Jason Devitt says, stopping users installing non-Apple (or Apple-approved) software means that the cost of sending messages goes from (potentially) zero, to $5,000 per megabyte:

    Steve typed “Sounds great. See you there.” 28 characters, 28 bytes. Call it 30. What does it cost to transmit 30 bytes?

    * iChat on my Macbook: zero.
    * iChat running on an iPhone using WiFi: zero.
    * iChat running on an iPhone using Cingular’s GPRS/EDGE data network: 6 hundredths of a penny.
    * Steve’s ‘cool new text messaging app’ on an iPhone: 15c.

    A nickel and a dime.

    15c for 30 bytes = $0.15 X 1,000,000 / 30 = $5,000 per megabyte.

    “Yes, but it isn’t really $5,000,” you say. It is if you are Cingular, and you handle a few billion messages like this each quarter.

    … [I] assumed that I would be able to install iChat myself. Or better still Adium, which supports AIM, MSN, ICQ, and Jabber. But I will not be able to do that because … it will not be possible to install applications on the iPhone without the approval of Cingular and Apple… But as a consumer, I have a choice. And for now the ability to install any application that I want leaves phones powered by Windows Mobile, Symbian, Linux, RIM, and Palm OS with some major advantages over the iPhone.

    Aside from the price discrimination (and business model) issue (see also Control & Networks), one thing that strikes me about a phone with a flat touch screen is simply how much less haptic feedback the user gets.

    I know people who can text competently without looking at the screen, or indeed the phone at all. They rely on the feel of the buttons, the pattern of raised and lowered areas and the sensation as the button is pressed, to know whether or not the character has actually been entered, and which character it was (based on how many times the button is pressed). I would imagine they would be rather slow with the iPhone.

  • Coincidence?

    Gmail ads related to mp3 being played?

    A few minutes ago I was playing a track in Winamp, with Gmail open in an Opera window, and on refreshing Gmail, the Google ‘web clip’ at the top of the inbox display contained the same phrase, ‘jet stream’, as the track.

    Is that merely a coincidence, or does Gmail monitor what music is being played by a user? I don’t have Google Desktop or Toolbar or any of that installed.

    Shaping behaviour: Part 2

    In part 1 of ‘Shaping behaviour’, we took a look at ‘sticks and carrots’ as approaches for shaping (or changing) people’s behaviour. It’s especially worth reading and thinking about the comments on that post as there are some very thoughtful analyses which go beyond my rather cursory treatment. ‘Shaping behaviour’ is a vast field, encompassing pretty much all of politics, advertising and marketing alongside much of religion, education, psychology (and psychiatry?), product and graphic design.

    The ‘sticks, carrots and speedometers’ classification was originally mentioned to me as a possible method by Chris Vanstone, of the UK Design Council’s former research arm, RED. The idea is that you can get people to change their behaviour by persuading (or forcing) them with ‘sticks’ (punishment/disincentives), ‘carrots’ (rewards) or ‘speedometers’ (showing them the results of their actions, how they’re doing, or how well they could be doing if they changed their behaviour). Having looked at sticks and carrots – and found the classification rather limiting – let’s take a look at speedometers.

    Some gauges provide information which directly relates to a user’s actions at that time. An actual speedometer or rev counter allows the user to determine what effect his or her actions are having on a vehicle, and take corrective action if the information displayed is outside the ‘correct’ range (of course there are other factors, such as the resistance to motion from drag or going uphill, and if one can hear the engine, a rev counter’s perhaps not really necessary, but I digress). Other gauges, such as fuel or temperature gauges (see photo at top) show us information over which we can’t have so much direct influence (or, in the case of a clock, say, no influence…) but about which we need to take action if certain levels are reached. Certainly, we change our behaviour as a result of taking in the information displayed. Usually. And the speedometer can of course be a metaphor for other methods of feedback or information displays – which I’ll get to later on.

    Energy use

    Sticking with physical gauges for the moment, in recent times there’s been a lot of design effort put into devices which monitor and display our energy or fuel use, with the hope that they’ll persuade us to change our behaviour, or bring to our attention which devices (e.g. in a home) are more power-hungry than others in an immediately persuasive way. The Design Council’s Future Currents project, which investigated a range of interesting techniques and design approaches, put the idea well:

    Energy is invisible, which makes it difficult to control. We can give people the tools to monitor their own energy use. Studies show that if people can see what they’re using, they use up to 15% less energy.

    An anecdote in Kalle Lasn’s Design Anarchy claims an even larger reduction:

    The manager of a housing co-op was increasingly frustrated with her tenants. No matter how much she reminded and badgered them… the tenants would not, could not reduce their energy consumption. Finally she hit an idea. What would happen, she wondered, if the electricity meters were moved from the basement to a conspicuous spot right beside the front door, so that each time the tenants left or entered their home, they could see how fast their meter was whirring? The meters were moved. Lo and behold, within a few weeks electricity consumption fell 30 percent.

    (It’s not clear whether there were individual meters so tenants could see each other’s consumption – that kind of control by embarrassment, or social pressure, may be effective in this free-rider or unequal contribution situation.)

    The convergence of new monitoring and connectivity technologies such as home wireless networks and RFID, with the pressure to scrutinise our environmental impact, has meant that there are more opportunities for potentially persuasive, interesting ways of approaching this area. Tom Coates has some good thoughts on this, and the relation to continuous monitoring of other parts of our (and others’) lives, and how fascinating it can be. Wattson (thanks to both Richard Reynolds and Michelle Douglas for originally bringing this to my attention) takes an especially ‘designer’ approach, becoming a coffee-table talking point as well as showing (in different display modes) the power currently being used, the costs, and, via a coloured glow projected onto the table below, a non-numerical indication of the intensity of power usage. Similarly playful methods are used in some of the Static! projects from Stockholm’s Interactive Institute – perhaps, in fact, when the ‘event’ which occurs as the ‘speedometer’ registers more desirable values is exciting in itself, the technique is closer to a ‘carrot’ than a speedometer.

    EU energy label A mess of adaptors
    Left: The Energy Label, required on certain products/packaging in the EU; Right: A typical mess of adaptors powering home electronic equipment. Here we have a scanner, a power drill charger, a printer (plug hidden), a battery charger and a cutting plotter. How easy is it for a consumer to audit the power usage of this kind of mess?

    The related debate over standby buttons on home electrical equipment which I covered briefly in July last year, brought home an important point to me, as someone who’s worked on quite a few consumer electronic products powered from adaptors: many users think that if a red LED is on when the product is ‘off’, that little LED is all that’s being powered. That’s quite an important issue when it comes to consumers having a better understanding of their home energy use.

    When seeing the Wattson and Future Currents projects for the first time, I was tempted to say “well, why don’t people just look at the power ratings on the appliances they buy?” but soon realised that that’s a pretty entrenched engineering mindset rearing itself in my mind. People don’t want to have to look on a label on the back of the product. They mostly don’t think about energy use when buying products. Even the use of ‘green’ labelling on the front of products (e.g. the EU label shown above) doesn’t hit home the actual monetary costs of different devices over typical usage periods. In this sense, monitoring devices which really get the user interested in using products more efficiently do seem to be very much worth it, even when they themselves use more power than strictly ‘necessary’.

    (There are a few points I’d like to make about home lighting and ‘energy saving’ light bulbs, especially since some aspects of the recent blogosphere commentary made me think a little further, but they can wait for another day…)

    Economy gauges

    Left: A traditional analogue vacuum gauge showing ‘fuel economy’. Image from brochure for Reliant Rialto 2, 1984; Right: Toyota’s Eco Drive meter from the Camry – image from HybridCars.com. As an aside, I have no idea how 35-40 mpg can be considered ‘excellent’! What year is this?

    Moving away from home electricity consumption, the increased prevalence of electronic in-car trip computers, usually built-in, has meant that second-by-second fuel economy read-outs are much more common, and can again inspire a kind of self-challenge to maximise economy while driving. As the miles-per-gallon (or perhaps L/100 km) figure drops (or increases) with every blip on the accelerator or rapid acceleration from the traffic lights, drivers really can train themselves to change their behaviour (indeed, I know a couple of people who are constantly shifting their gaze from the road ahead down to, alternately, the speedometer and the miles per gallon figure, to see “how well they are doing”, which is not necessarily ideal). Economy gauges in cars are nothing new – vacuum gauges were quite a popular home-fit accessory at one time, but they generally did not directly relate to the fuel consumption per distance travelled, merely the vacuum in the inlet manifold, hence the amount of fuel-air mixture being drawn through, whether or not the car were moving.

    An alternative type of economy gauge was that once used by Volvo and other manufacturers, which compared the engine’s rpm (or the gearbox rpm?) to the gear selected (manual only, I presume) and illuminated a gearstick icon when the driver was in the ‘wrong’ gear, i.e. driving at less than optimum efficiency. Even more simply, some car companies used to mark the ‘gearchange points’ on the speedometer with dots at certain speeds – assuming the driver could not tell from the engine note that the gear engaged was too high or low, the dots would at least give some indication, though of course different driving conditions and loads would make the dots’ positions guidelines rather than absolutes. (I do have photographs of both these designs, somewhere, but will have to post them at some point in the future.)

    Speedometers and control

    Certainly, then, physical speedometers and gauges can have an effect on users’ behaviour and can encourage people to change; technology seems to be making this easier and more interesting and engaging. There are so many opportunities; already in some countries, there are roadside speed displays to make motorists aware of their speed (which present a fun challenge for drivers, or indeed cyclists, wanting to see what they can achieve) – how long before we have roadside CO2 monitoring (with displays)?

    But are any of these ‘architectures of control’?

    In the sense that they are methods of persuasion rather than methods of restriction or enforcement, they are on one side of a line with rigid control on the other, but when we look at techniques such as the control by embarrassment, or social pressure mentioned earlier, we can see that there is some kind of continuum related to how the information displayed by the speedometer (of whatever form) is used: if only you can see your personal energy usage habits within a house, you can make the choice whether or not to change your behaviour, but if the rest of your household can also see your habits, and see that you’re costing them unnecessary money, the pressure on you to change is much greater.

    That, I think, is where the ‘control’ element comes in. Say that every household’s yearly carbon emissions (however this were to be calculated) were monitored. If the information were available to the householders, it may give them food for thought, and may inspire changing behaviour. If the information were available to the government, it may lead to taxation, and may lead to changing behaviour. If the information were legally required to be displayed on an illuminated sign outside the house, so neighbours could see who was “getting away with more carbon emissions”, it may (perhaps) lead to people changing behaviour too, or risk recriminations from the community, possibly worse than just social embarrassment. This last case is pretty much speedometer + blackmail, and I would say that that crosses the line to become control. If you want to fit in, and not be censured by others, you have to conform. That is an architecture of control, very much so, and hence we can see that speedometers, as with many other possible design elements, can be used as part of systems of control, but are not in themselves necessarily political. It’s the way they’re used that makes them, possibly, controversial.

    The speedometer metaphor

    Metaphorically, of course, a speedometer can be any method of making users aware of their behaviour, or the link between their behaviour and some other effect. Many of the examples studied and created by Stanford’s Captology / Persuasive Technology lab fall into this area, offering users feedback on their actions, or encouraging them to behave in a certain way (e.g. giving up smoking) through highlighting causal relationships.

    But isn’t this, to some extent, what all persuasion is about, if we allow our ‘speedometer’ to have, in some situations, only two values (on/’good’ vs off/’bad’)? Everything ‘persuasive’, from advertising campaigns to counselling, is about saying “A is happening/not happening because you’re doing/not doing B; it will be better/stop happening if you stop/start doing C.” A speedometer is saying “You’re doing OK because this is the result of your actions” or “Look at the results of your actions – you need to change what you’re doing!”

    Is it true, then to say that any situation where one entity (person/animal/plant) is trying to change the behaviour of another entity is resolved either by control (forcing the change in behaviour) or persuasion (inspiring the change in behaviour), or a combination of the two (e.g. by tricking the entity into changing behaviour)?

    Or is that too simplistic?

    Sniffing out censorship

    News Sniffer
    Image from News Sniffer

    News Sniffer‘s Revisionista monitors alterations to published news stories from a variety of sources by comparing RSS feeds, sometimes revealing subsequently redacted information or changes of opinion (e.g. note the removed phrase in the first paragraph of this story about Cuba). While many of the changes are simply re-wordings for clarity or to correct grammatical errors, there are certainly also some instances of more substantial revisions – see the ‘recommended’ list.

    Perhaps more revealing is News Sniffer’s Watch Your Mouth, which shows the reactively moderated comments removed from the BBC’s ‘Have Your Say’ threads. I’ve been reading this for a while – in fact I think I might have been one of the first subscribers via Bloglines – and am still amazed by just how many comments are removed by the BBC’s moderators, often making points which, though maybe controversial, are very much the voice of the common man and woman. Some are offensive, yes; others are genuine expressions of frustration or even first-hand annotations to or clarifications of aspects of the story above. Many are critical of the BBC, including those criticising the moderators for censorship of the very comments under dicsussion.
