Another charging opportunity?

A knife blade cutting the cable of a generic charger/adaptor

Last month, an Apple patent application was published describing a method of “Protecting electronic devices from extended unauthorized use” - effectively a ‘charging rights management’ system.

New Scientist and OhGizmo have stories explaining the system; while the stated intention is to make stolen devices less useful/valuable (by preventing a thief charging them with unauthorised chargers), readers’ comments on both stories are as cynical as one would expect: depending on how the system is implemented, it could also prevent the owner of a device from buying a non-Apple-authorised replacement (or spare) charger, or from borrowing a friend’s charger, and in this sense it could simply be another way of creating a proprietary lock-in, another way to ‘charge’ the customer, as it were.

It also looks as though it would play havoc with clever homebrew charging systems such as Limor Fried’s Minty Boost (incidentally the subject of a recent airline security débâcle) and similar commercial alternatives such as Mayhem’s Anycharge, although these are already defeated by a few devices which require special drivers to allow charging.

Reading Apple’s patent application, what is claimed is fairly broad with regard to the criteria for deciding whether or not re-charging should be allowed - in addition to charger-identification-based methods (i.e. the device queries the charger for a unique ID, or the charger provides it, perhaps modulated with the charging waveform) there are methods involving authentication based on a code provided to the original purchaser (when you plug in a charger the device has never ’seen’ before, it asks you for a security code to prove that you are a legitimate user), remote disabling via connection to a server, or even geographically-based disabling (using GPS: if the device goes outside of a certain area, the charging function will be disabled).

All in all, this seems an odd patent. Apple’s (patent attorneys’) rather hyperbolic statement (Description, 0018) that:

These devices (e.g., portable electronic devices, mechanical toys) are generally valuable and/or may contain valuable data. Unfortunately, theft of more popular electronic devices such as the Apple iPod music-player has become a serious problem. In a few reported cases, owners of the Apple iPod themselves have been seriously injured or even murdered.

…is no doubt true to some extent, but if the desire is really to make a stolen iPod worthless, then I would have expected Apple to lock each device in total to a single user - not even allowing it to be powered up without authentication. Just applying the authentication to the charging method seems rather arbitrary. (It’s also interesting to see the description of “valuable data”: surely in the case that Apple is aware that a device has been stolen, it could provide the legitimate owner of the device with all his or her iTunes music again, since the marginal copying cost is zero. And if the stolen device no longer functions, the RIAA need not panic about ‘unauthorised’ copies existing! But I doubt that’s even entered into any of the thinking around this.)

Whether or not the motives of discouraging theft are honourable or worthwhile, there is the potential for this sort of measure to cause signficant inconvenience and frustration for users (and second-hand buyers, for example - if the device doesn’t come with the original charger or the authentication code) along with incurring extra costs, for little real ‘theft deterrent’ benefit. How long before the ’security’ system is cracked? A couple of months after the device is released? At that point it will be worth stealing new iPods again.

(Many thanks to Michael O’Donnell of PDD for letting me know about this!)

UPDATE: Freedom to Tinker has now picked up this story too, with some interesting commentary.

A couple of stories from the Consumerist

Is Sylvester Stallone Taking Over Your TV?” - anecdotal suggestion that some digital video recorders may be attempting to ‘push’ certain movie franchises in the run-up to release by recording (unrequested) previous titles in a series, or with the same actors.

Well, this is totally impossible to confirm, but we just got a complaint from a reader saying that their DVR was recording Sylvester Stallone movies all on its own. They think this might be some sort of sly promotion tied into the new Rocky movie. Is this happening to anyone else, or do these people have a possessed DVR?

And from the comments:

I have Time Warner in NYC as well, and a month ago Bond movies started automatically queuing up. I thought it was a fluke, but that was right when Casino Royale was hitting wasn’t it? I’m the only person who touches my DVR, so it wasn’t a prank.


Also, in a similar vein to my earlier post on the price structures of ticketing systems, Consumerist reports on US Postal Service stamp vending machines, which require a minimum purchase of $1 (it’s suggested that this is in violation of Visa’s merchant agreements).

While minimum purchase amounts for credit card use are fairly common, (especially with smaller businesses, due to the transaction fees charged by the card company) when a minimum price is imposed on a system such as this stamp vending machine - and only made clear to the user after he or she has already selected the desired item - the practice seems somewhat sneaky. Many people who use a stamp vending machine will do so since they are in a rush, need to send that item of mail, and haven’t got time to wait in a queue. If you only wanted a 39 cent stamp, you’re forced to pay an additional 61 cents (more, in fact, since the stamp face values don’t add up to exactly $1) just to accomplish what you set out to do.

Still, you do get the extra stamp(s) you were ‘forced’ to buy, and at least they don’t go out of date or expire like a bus ticket or a parking ticket.

Shaping behaviour: Part 1

A couple of months ago I posted about the ’shaping behaviour’ research of RED, part of the UK Design Council. At the time I noted in passing a classification of design approaches for shaping behaviour, mentioned by RED’s Chris Vanstone: “stick*, carrot or speedometer.” It’s worth looking further at this classification and how it relates to the spectrum of control, especially in a technology context:

Yes, it's a stick (well, a branch), next to a PCB

Stick

If we define ’stick’ as ‘punishing the user for attempted deviation from prescribed behaviour’, then many of the architectures of control we’ve examined on this site demonstrate the stick approach. They’re not explicitly ‘technologies of punishment’ in Foucault’s phrase, but rather a form of structural punishment. The thinking seems to be (for example):

  • If you try to sleep on this bench, you will be uncomfortable (and hence won’t do it again)
  • If you try to copy a DVD, your copy will be degraded and your time and blank DVD wasted (and hence you won’t do it again, or will buy another authorised original)
  • If you try to view our website using a competitor’s browser, your experience will be broken (and hence you’ll switch to our browser)
  • If you try to skateboard here, your board will be damaged and you will be maimed (and hence you won’t do it again)
  • …and so on. There are numerous other examples from software and urban planning, especially.

    The thing is, though, for each of those ’sticks’, a large percentage of people will not be obedient in the face of the ‘punishment’. They’ll try to find a way round it: a way of achieving their original objective but avoiding the punishment. They’ll search for what others in similar situations have done (e.g. DeCSS in the DVD example) or ask among friends until they find someone with the required expertise or who knows about an alternative. They may even actively destroy the ’stick’ that punishes them. In some cases they might not even understand that they’re being punished, simply seeing ‘the system’ as beyond their comprehension or stacked against them.

    Equally, there isn’t always a rational strategy behind the ’stick’ in the first place. The anti-homeless bench doesn’t ’solve’ the ‘problem of homelessness’. It just punishes those who try to lie down on it without offering an alternative. It’s punishment with no attempt at resolving the problem.

    If a stick does get people to change their behaviour in the intended way, it will be accompanied by resentment, anger and dissatisfaction. It may only be fear of the consequences which prevent actual rebellion. In short: using sticks to change people’s behaviour is not a good idea.

    Carrot

    A ‘carrot’ means offering users an incentive to change their behaviour. This moves away from actual control to something closer to some aspects of captology - making a persuasive case for behaviour change through demonstrating its benefits rather than punishing those who disobey.

    To some extent, control and incentives may be incompatible. Taking away functionality from users then showing them how they can get it back (usually by paying something) might be a classic combined “carrot and stick” technique, but it’s also bordering on a protection racket, and it doesn’t fool many people.

    However, can control be used in conjunction with genuine incentives to serve the agendas of both sides? Electric lights that turn off automatically if no-one’s in the room take some control away from the user, but also offer benefits to both the user (lower electricity bills) and society as a whole (less energy used). But if they turn off automatically, is there actually any incentive for the user to change his or her behaviour? If we’re always spoon-fed, will we ever learn?

    Perhaps mistake-proofing measures or forcing functions which allow a user to increase his or her productivity or safety, in return for giving up some ‘control’ - which may not be highly valued anyway - fit the definition best. If I’m working in a factory painting coachlines on hand-built bicycles, a steady guide arm that damps my arm vibrations - but only if I also take care as well - takes some control away from me, but also prevents me making mistakes, allowing me to paint more coachlines per hour, more accurately. It also helps my employer.

    But that’s a very weak degree of control. Unless anyone can come up with any counter-examples, I would suggest that providing real incentives for users to change their behaviour is fundamentally a very different approach to the ‘control mindset’ (unless you are trying to trick people by offering false incentives, or by understating what they could lose by changing their behaviour).

    I’ll get round to speedometers in a future post, since this approach is worthy of a deeper treatment.

    *The phrase “carrot and stick” seems now universally to imply “offering incentives with one hand and punishment with the other” (though not necessarily at the same time), rather than the “carrot dangling from a stick, just out of reach” meaning (i.e. “motivating people to perform with incentives which will never be fulfilled”) which I first assumed it to have when I heard the phrase as a kid (I’m not the only one with this issue). In this post, I’ll use “stick” to mean “punishment”.

    Sniffing out censorship

    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.

    Disaffordances and engineering obedience

    Based on Don Norman's famous teapot

    Last month I asked, in response to some criticism, whether there was a better term than ‘architectures of control’ for the loose category of stuff discussed on this site. The response was great - thanks to all who got in touch or commented.

    James Young, an artist & designer from Oregon, thoughtfully suggested obedience engineering (along with ‘restrictive’, ‘regulatory’ and ’supervisory’ engineering - as extensions to the term ‘functional engineering’, which I understand but have always thought was something of a tautology!). Obedience engineering has a neat ring to it - implying external authority - and describes most of the examples on this site pretty well, both politically- and economically-motivated control.

    In most cases the ‘obedience’ is to serve a higher power’s strategy in some way, whether that’s forcing customers to buy razor blades more often or stopping the homeless sleeping in a park. In some cases, though, the obedience serves the user him or herself (usually in addition to a higher power in one way or another), such as various forcing functions and mistake-proofing aimed at ensuring safe operation of products or machines - it’s a similar kind of obedience to obeying your parents’ instructions not to put those fireworks in your pocket: for your own safety as well as their peace of mind. I’m aware that most of the examples I use come across as rather negative (and usually paranoid), so it’s important to remember that a lot of ‘control’ can have beneficial intentions (at least) for the user or society as a whole.

    Reversing the phrase, ‘engineering/ed obedience’ and ‘designing/ed obedience’ also have a lot of merit, either as titles themselves or as explanatory subtitles/taglines. Architectures of control: engineered obedience?

    (I don’t necessarily want to get into the design-or-engineering debate here. Both terms mean many different things to different people, and the use of either could immediately put off or attract people who would find something of interest here. There are readers here from a fair variety of fields; I know people whose eyes go blank when engineering is mentioned, and others who would assume that a site about design must be dealing purely with aesthetics or artisan furniture. Personally I see all design and engineering (and art and programming - as Paul Graham recognised) as pretty much the same subject, and indeed, perhaps the intersection of the physical and cognitive sciences with the environment, history and culture, but that’s something for another day…)

    Jim Lipsey, a project engineer from Chicago, suggests disaffordances as a synonym for architectures of control - again, a neat and clever suggestion which also has the benefit of immediately conveying some understanding of the concept to product design and usability professionals and academics.

    Nevertheless, it’s worth running over briefly what ‘affordances’ are in the first place, to explain why ‘disaffordances’ might be a good term. In its original definition, an affordance is a possible function of, or interaction with, a device. A chair gives me the affordance of sitting on it, but also standing on it, or hitting someone with it. This is a simplification of psychologist James J. Gibson’s definition of affordances. Donald Norman - author of the legendary The Design of Everyday Things - extended the concept to what he later called perceived affordances: while I might use a chair to hit someone, my cultural conditioning, together with the form of the chair, suggest that I should sit on it. Norman’s affordances are thus what people think they can do (or should) with objects, which may be different to what they actually can do with them:

    Usefulness and usability
    From ‘Affordances‘ by Mads Soegaard: ‘Separating affordances from the perceptual information that specifies affordances. Adapted from Gaver (1991).’

    This Interaction-Design.org encyclopaedia article (from which the above diagram comes) is a very clear treatment fo the subject, as are Don Norman’s own ‘Affordances and design‘, and indeed Wikipedia’s entry.

    Disaffordances, then, would imply either products with functionality deliberately removed (which fits many architectures of control example well - most obviously ‘feature deletion‘) or with the functionality deliberately hidden or obscured to reduce users’ ability to use the product in certain ways, or a combination of the two. That does take care of most of the examples I’ve looked at on this site, though I worry a bit about having to concatenate the two definitions. I also feel that quite a lot of architectures of control are actively attempting to force users to change their behaviour, whilst disaffordance implies a more passive state of affairs.

    I think it may be best to use the term ‘disaffordance’ specifically to describe the practice of ‘disenfranchising’ users from the functions their products, systems or environments might otherwise provide (or have previously provided). This covers a lot of the things we discuss here (though it’s important to remember that architectures of control are deliberate, intentional, often strategic disaffordances, rather than something that’s difficult to use or hides its features through incompetent design); the the term doesn’t have much currency (yet), but I’ve done as Jim suggests and registered disaffordances.com and disaffordances.co.uk.

    This blog is still maturing, and evolving, as is the field of thinking and practice which it charts. I’m sure plenty of new terminology (and jargon) will become commonplace in the years ahead. And the site will continue, in the words of the fantastic Gossip, ‘standing in the way of control‘ [mp3 link].
