On the ground running: Lessons from experience design

A superb article by Adam Greenfield and a must read for UX designers.

We live, it seems, in an age in which the long-standing and pleasingly crisp distinctions between what constitutes a “product” and what a “service” are beginning to break down. Even in the early days of this evolutionary shift, we can already see that the implications for both individual designers and the profession of design as a whole are likely to be deep and lasting.

Traditionally, a product was physical and discrete – something obviously demarcated in space but, equally, in time. The designer’s brief rarely extended to much more than the form of an object, at most encompassing the contours of its use immediately after purchase, and that extending only to a narrow range of scenarios and anticipated users. But driven by lightweight and ubiquitous networking, and the open standards it gives rise to, all of this has started to change: no longer can the designer of any product assume that it will stand on its own, autonomous and serenely uninvolved with the wider world, for its entire lifetime of use.

The already-classic example is, of course, the product-service ecology Apple devised for their iPod. Considering the close integration between iPod, the physical device, iTunes, the desktop application, and iTunes Music Store, the online environment, it’s clear that Apple understood relatively early on that the only way their contender would be likely to gain traction in an already crowded field of MP3 players was not to frame it as an MP3 player at all.

Their stroke of genius – and it’s easy to see it as such now, in retrospect, but most commentators missed it at the time – lay in positing the iPod not so much as a stand-alone device, but as the tangible presence in your life of a larger and much more ambitious experience. Apple grasped, before any of their competitors, that evoking a truly pleasurable experience of use transcended questions of the placement of controls or the sequence of menu items, as important as these things are. It required a consistency of conception extending from the moment you opened the iPod’s box for the first time to the way it felt to find new music for it on the iTunes service.

There are two nontrivial insights here, and maybe we’d benefit from unpacking them a little. The first is that the perceived quality of the iPod in use depends to an unusual extent on Apple’s framing what you’re actually buying from them holistically, at the level of the whole undertaking rather than that of its component parts – they get that the product is no longer an isolated entity, but a way of gaining access to content which might ultimately live elsewhere. The second is that getting this “product” right means accounting for your interactions with it across multiple channels, and even more importantly, over time.

In the iPod ecology, then, we have traditional industrial- and interaction-design concerns interwoven with elements which have more usually characterized the architecture of services. When you consider that such interweavings are becoming increasingly common in our day-to-day lives – you can grant an older cellphone entirely features by blowing updated firmware into it, while certain models of Lexus automobiles now come with a subscription to real-time traffic information – the time would appear to be ripe for a new kind of designer to take center stage.

What might we call such a person? Here’s a hint: it’s neither a “graphic” nor a “Web” nor even an “interaction” designer.

Toward the Total Experience

None of the shifts outlined above, mind you, have gone unnoticed by the broader digital design profession, nor has that profession been slow to recognize the potential opportunities involved. Over the past few years, the domain of practice known (if only briefly) as “user experience” has begun to accommodate the new realities on the ground, recasting itself as “experience design.”

Whether the emergence of a self-conscious experience design community reflects a canny land-grab on the part of a few visible and reasonably influential practitioners, an underlying recognition that our technosocial practices have transcended the rather limited model of the “user” ultimately derived from old-school human-computer interaction studies, boredom with a thoroughly mapped landscape, or something else entirely, it’s undeniably been a successful way of framing things.

As far back as 2001, no less authoritative a body than AIGA (”the professional association for design”) had lent its imprimatur to the fledgling field, with an AIGA conference defining experience design as being concerned with a product’s “entire lifecycle with a customer, from before they perceive the need to when they discard it.”

In the years since, the discourse of experience design has steadily gathered authority, offering as it does a way to wrestle and wrangle with the new complexity of the built environment and the objects we encounter in it. (In this, it parallels the emergence of actor-network theory in the academy, a line of thought that accounts for interactions between extended networks of people, ideas, technologies and artifacts. Something’s clearly in the air.)

On its face, this outlook has considerable appeal. There is still no better advice for design students than that offered by the 20th century architect Eliel Saarinen (father of Eero): that things should always be designed with reference to their “next larger context.” Experience design would appear to incorporate this recognition from the beginning, which would certainly better position it to respond to the manifold challenges of design for a networked world than more tactical arts.

But it turns out that there’s a serious flaw in this way of thinking. Ensuring that all phases and aspects of someone’s interaction with a product/service ecology align with the desired vision requires that something little short of total control be asserted over their choices. This, in turn, leaves little room for the self-evident (and lovely) messiness of our lives, not much in the way of flexibility should the scenario of use deviate to any significant degree from that contemplated at design time.

As it happens, another Apple product provides a perfect illustration of the potential pitfalls involved in such overly designed experiences – in this case, the cross-branded Nike+ iPod Sport Kit.

As envisioned, the Nike+ ecology consists of several physical products – a biotelemetric transponder, any of a range of Nike sneakers compatible with it, and an iPod nano – and an online environment where the results of one’s uploaded runs are subjected to a variety of mappings, visualizations and pseudo-statistical analyses. (The desktop iTunes application mediates the flow of data between device and Web site.)

One’s first few runs with Nike+ are smooth and pleasurable, replete with the kind of “thoughtful” touches that generally get lauded as good experience design – Lance Armstrong congratulating you every time your run time exceeds the previous personal best, and so on. But it rapidly becomes apparent that all the smoothness in the Nike+ experience comes at a cost, that it really clicks only if you and everything about the way you use the system conform fairly narrowly to an imaginary ideal.

These insightful comments from Nokia’s Chris Heathcote are spot on:

Designing for one person creates tight end-to-end services. But few companies control the complete end-to-end, and in fact, customers (people!) are wary – it’s normally an excuse to bleed more money out of people more regularly (“we can sell a product and a subscription!”) and to lock people in (how do you get your data our of Nike+?).

He’s absolutely correct, on all counts. In fact, most users will find that their experience is constrained in several ways:

– For quite awhile, the selection of shoes available to prospective Nike+ runners was quite limited: not merely to Beaverton’s own shoes, but to one particular line among their offerings. If you wanted to try Nike+ with, say, a pair of Nike Frees that imitate the biomechanics of running barefoot, you were out of luck.

Although Nike recently announced that all of their shoes would henceforth be fully compatible with the system, it may not matter; as it turns out, hacking Nike+ so it works with non-approved shoes is a simple matter of duct-taping the transponder to whatever trainers you already have lying around the house. That the system works equally fine with its input taped to an old pair of Adidas is an indication that this particular dimension of control was not definitive of the experience. This is a point to which we’ll be returning.

– The sense of needless constraint is, perhaps, equally imposing on the Apple side of the house: of all the available models of iPod, only the nano works with Nike+. Given that other models come equipped with the appropriate connector, there’s no obvious justification for this decision either.

– Nike+ motivates the runner by announcing the achievement of incremental performance goals – you’re reminded of elapsed run time at five-minute intervals, for example, in addition to when you’ve hit the halfway point. Apple has thought things through enough to realize that different people are motivated by different triggers, so they’ve at least provided a choice between male and female voice actors.

But the voiceovers are such an intimate presence that any offness in them registers disproportionately. Since the system affords no way to upload alternative motivators – a coach or drill instructor, a personal hero, a lover – this is likely to remain a sore point.

– What about users, and uses, of the system outside the envelope imagined by its designers? Nike+ feels unnecessarily over-optimized for a single kind of runner, and a single kind of run. (Heathcote nails it: “I can see the persona on the flipchart now,” and anyone who’s worked in the field for more than about ten minutes knows precisely what he’s talking about.)

There’s nothing in the system’s technical capabilities that prevents it being of utility to walkers, for example. They may not necessarily be as sexysweaty as the users featured on the Nike+ site, but would surely appreciate being able to take advantage of its pedometer and calorie-tracking features. Why exclude them, literally by design?

– Perhaps the deepest question facing the Nike+ online experience is that of the t dimension. Manufacturers like Sony and Nike who rely heavily on complicated, Flash-driven experience sites for their products often find the sites hard to maintain or update over anything beyond the short term.

By contrast, of course, for a great many of its adherents, running is a lifelong activity. Where will they turn in three years if Nike decides there’s no longer any percentage in supporting Nike+, or if the latest release of iTunes fails to mediate smoothly between device and site? Will they be forced into an expensive, exhausting cycle of multiple upgrades and compatibility hurdles, or, still worse, find themselves in a technological cul de sac? The more the desired brand experience relies on a concatenation of closed systems from different manufacturers, each of which is subject to revision (to say nothing of a realignment of corporate priorities), the less likely it is to survive intact over time.

As Heathcote suggests, many of these problems could be obviated by opening up the Nike+ platform, allowing people to swap in shoes and other components of their choosing, or even to build custom mashups of their own with the data it generates.

This is, admittedly, not likely to be terribly appealing advice from the point of view of those stakeholders committed to a heavily-branded experience. From this perspective, it’s an offering of Nike and Apple: why on earth should they design it so shoes or music players from other manufacturers work equally well?

But if the choice is between an overcontrol that will predictably result in an eventual breakdown, and a flexibility that admits other players but also affords more satisfying long-term outcomes, which would you rather have your brand associated with? In the final analysis, about all that can be said about end-to-end control of a multi-touchpoint customer interaction is that it results in a perfect experience….except, of course, for when it doesn’t.

Fast train to nowhere

Several years ago – and it was one of the first occasions I personally recall hearing the phrase “experience design,” now that I think about it – design firm IDEO presented their work on the design of Amtrak’s then-new high-speed service, Acela.

At the time, IDEO’s work on Acela could fairly be regarded as exemplary. They surely had the right instincts: originally engaged to design the cabin of a railway coach, they understood that the actual design challenge before them was significantly broader, that the form of the coach was merely a small part of what travelling by train is all about. Still more insightfully, in accordance with Eliel Saarinen’s wise counsel, they had situated that portion of the journey during which a customer was travelling on rails as merely the central segment of a far longer experiential arc.

IDEO divided this arc into ten distinct phases; their conception of an Acela trip began even before passengers had necessarily settled on travelling by train, accounted for the rituals of arriving at the station and purchasing tickets, and followed until they had transferred to another mode of transportation upon arrival at the destination.

The clear intention was to ensure that the customer interaction inscribed in each of these phases was designed to the same high standards as an IDEO mouse or shopping cart. But with the best of intentions, this way of thinking led Acela into error.

The assumptions embedded in the plan are too tightly coupled to one another. They feed from one to the next – remember the word – seamlessly, like brittle airline timetables so tightly scheduled that a delay anywhere in the densely-interwoven mesh of connections cascades through the entire system. When it all succeeds, it’s magnificent, but if any aspect of it fails, the whole thing falls apart.

That the whole thing has, in fact, fallen apart will be readily attested to by anyone who’s taken the Acela lately. Conceived as a competitor to world-class rail services of long standing, like France’s TGV and the Japanese shinkansen, the level of amenity Acela offers its passengers simply doesn’t even come close. From the frankly broken ticketing process, to the tatty waiting areas (it would be stretching credibility to call them “lounges”), to the flickering, dysfunctional arrival/departure screens, to the occasional surliness of onboard personnel, Acela is a system that has failed to uphold the minimal standards seasoned travellers expect from a would-be global contender. Even Korea’s KTX offers a more refined and a more pleasant intercity service.

Notice that these pitfalls have a commonality, that of maintenance. As originally devised, each of the components of the Acela proposition made perfect sense, but they have been allowed to degrade over time. Those that have defaulted drag down the perception of those left behind, until any clever touches there may be in the design of the train cabin or the station signage no longer even register against the net impression of hassle and irritation.

This tends to be a particularly acute issue wherever a designed ecology brings human beings face to face with one another: as things now stand, experience design’s Achilles heel is that contemporary American customer service standards are nowhere near the level of refinement routinely achieved by product and interactive designers. A combination of low wages, disinvestment in training, habitual recourse to offshoring, and deeper cultural factors has left American businesses without a large pool of workers motivated to provide customer service at the level routinely specified by designers. The result is that experiences seamless on paper break down badly the moment a human being enters the loop; the necessary follow-through simply isn’t there.

The suggestion here is not that these crucial interactions be left to chance, to design by committee or to the exigencies of the moment. But there are real limits on what a design organization can reasonably expect to achieve. Designers may well be able to specify the degree to which a seat reclines, the font in which a sign is set, or the sleek lines of a uniform – but not the behavior of the person in that uniform, and ultimately, that’s far more likely to determine the tenor of any experience. Acela’s lesson for experience designers is simple, one that most of us learned in childhood: don’t bite off more than you can chew.

Pumas for Achilles

People, of course, aren’t always the weakest link in a product/service ecology. Puma’s Trainaway line provides us with a perfect illustration of some the pitfalls that await when total experience designs cannot, for one reason or another, be carried through.

Ambitious in conception, Trainaway is positioned as sleek, lightweight running gear for whatever’s left of the jet set, specifically designed to help people maintain their fitness routines while travelling. In addition to the shoes and clothes, the ecology comprises a series of cardkey-sized, plasticized maps to running routes in major cities worldwide, slickly-produced SoundWalk MP3 audio guides, and alliances with suitably aspirational partners, such as the W hotel chain.

One of the most appealing aspects of Trainaway is that it’s clearly been conceived not simply as an integrated system of products but as a coherent experience. The trouble, as we’ve seen, is that such things are delicate, and delivering on them depends vitally on the smooth coordination of heterogeneous and inherently unstable components. In this instance, that smooth coordination is missing in multiple ways.

We’ve already seen how a lack of adequate employee preparation and training can undermine an experience proposition. When Puma’s own retail personnel don’t know how to explain or merchandise the Trainaway components on their own shelves, the augurs are not good, and indeed, it only gets worse when you visit a W hotel in an attempt to extend the Trainaway experience: the desk staff at New York’s W had never heard of the tie-in with Puma, and had absolutely no idea what if anything it required of them.

Such breakdowns in customer service are, by now, sadly predictable. But even at the raw level of product design, the necessary degree of follow-through is missing. The jacket has fittings and pockets for an integral fiber-optic safety lighting system that would admittedly be innovative, if the light source were anywhere to be found. (Despite being called out on the Web site as a product feature, neither customer service contacted via the site’s email form nor, again, the staff at Puma’s retail store were able to explain just how this feature is supposed to work.)

And then there are the blunders that only a self-conscious “experience” designer would make. The Trainaway shoe features an outboard slot for storage of your hotel’s cardkey; anyone who actually runs – even most nonrunners who spend a few minutes contemplating the question – would have a vivid sense for how rapidly and thoroughly this slot is going to be gunked up with the vile muck of street, path and trail. Given every possibility offered by an integrated collection, why on earth choose the bottom of the shoe for storage? This is the kind of too-clever-by-half “solution” that only someone trying to force-fit components into an imagined ecology would have introduced into the product development process.

Finally, the online components of the experience don’t appear to have been thought through with any particular clarity. However lavish, the audio guides are the kind of thing you listen to once, at most. A map of the Tiergarten does me little good should my travels happen to take me to Manila or Buenos Aires. And whatever other mistakes Apple and Nike may have made, the hassle involved in manually entering a long alphanumeric authorization code to download these goodies makes you positively nostalgic for the plug-and-play integration of Nike+.

Is Trainaway a complete disaster? No: at the end of the day, what you get for your money is still a perfectly serviceable array of running shoes and clothes. But it’s unclear, at best, if there’s actually any enhanced value to the consumer as a result of all the experience-design trappings. When so much time and effort are lavished on product, on advertising, on the design of a Web site, on maps and audioguides and other collateral, shouldn’t the ROI on tying these things together be more self-evident?

More fundamentally still, if the entire aim of the product/service is allowing you to maintain your fitness routine while travelling (”[m]ost often, even the best intentions result in gear that’s left idle, never making its way out of the suitcase”), we should ask ourselves whether design is even an appropriate response. This may simply be an issue that’s beyond the ability of an experience designer to affect.

So what might a more approproate ambit for design look like, in the context of complex networked product/service ecologies? How might someone interested in providing people with consistently high-quality experiences address the problems of overly brittle planning suffered, to different degrees, by Nike+, Acela and Trainaway? Some useful hints might be gleaned from domains as close to design as architecture – and as seemingly distant as cybernetics.

Conversations, not control

We’ve seen that highly designed experiences tend to suffer from a consistent range of limitations: physical components that are brittle, unreliable, or not delivered to specification to begin with; difficulties integrating those components with online environments, with desktop or mobile applications, and with human participants; and finally, the inherent unpredictability of any attempt to maintain consistent feel across technosocial systems of heterogeneous type and nature.

Could it be that more headway will ultimately be made when designers conceive of desired experiences as overarching but essentially open narratives, into which individual consumers can insert or demount components at will?

In architecture, the idea of maintaining precise control over the specification of an infrastructural framework, while ceding control over local circumstances to the user, is one with a respectable pedigree, so much so that it has historically appeared in a variety of places, times and guises.

The “kit of parts” approach – in which theoretically endless cities are generated by plugging housing, recreation, and production modules into circulation networks, like the pieces of some gigantic children’s construction set – is most often associated with the delightfully high-flying British collective of the 1960s known as Archigram. Similar tendencies characterized the work of Archigram’s direct Japanese contemporaries, the Metabolists.

Other architects went further still. Constant Nieuwenhuis’ New Babylon, Yona Friedman’s Spatial City and Cedric Price’s Fun Palace all envisioned immense open bays in which finer-grained control of the environment was left to individuals, or small groups. Meanwhile, Reyner Banham and the other prophets of “non-plan” architecture proposed that all but the most vestigial urban planning be done away with, the better to allow a community to find its own most vibrant mode of spatial expression.

There will be a great deal that contemporary experience designers can take from these examples, especially their sense of the continual, shifting, delicate negotiations between the overall perception of an ecology, and how that perception is locally inflected by the input of participants. (Similar ideas can be found in the thought of cybernetician Gordon Pask, who constructed human-computer interactions not as sterile control and feedback loops, but as “conversations” among a shifting retinue of observers and participants both technical and human.) Implicit in many of these visions is a stance that only in a loose and forgiving framework – what we might think of as an “underspecified” one – can the really valuable experiences happen.

There’s a tacit model underneath what is being proposed here, and if it seems familiar, it should: it’s the Internet. Years of working with the Internet and with the World Wide Web built on top of it have accustomed us to a logic of “small pieces, loosely joined,” in which the network is open-ended, effortlessly extensible, and robustly resilient to the failure of individual system components. Finally, this logic has begun to filter out into our experiences of the physical world – and imagine how much better offerings like Nike+ would be if they fully embraced it.

If absolutely top-shelf design organizations like IDEO and Apple are unable to fully encompass the challenges of everyday life in the real world, how much less so their less able peers? How, for example, would the Nike+ experience feel if its various touchpoints had been devised by Microsoft, the same institution that brought you Clippy, the Blue Screen of Death and the DRM-hobbled Zune? Isn’t it better, then, to open these systems up – to provide the APIs and other hooks that would allow people to configure them to their own liking?

This goes beyond William Gibson’s oft-quoted and unimpeachably correct observation that “the street finds its own uses for things,” toward the recognition that designers cannot, even in principle, encompass at design time the full range of uses to which their work will be put. In some respects, too, this is what human-computer interaction guru Don Norman is alluding to, when he argues that the person formerly known to experience design as the “user,” “customer,” or “consumer” needs to be understood as a human being before designers can do their work properly. Any other approach, he reasons, risks treating this person as an instrumental component, not as someone capable of fully participatory co-creation.

Norman is, of course, right, as far as he goes, but he doesn’t go nearly far enough. Truly making room for human prerogatives in the context of heavily-designed product/service hybrids means that, wherever possible, such systems ought to allow people to swap their own desired components in and out at will, to pull data out in a useful format, and to preserve value even where one or more component has broken down.

Does this mean that there is no justified role for the experience designer? No, of course not. Ultimately, though, the best solution may be to plan for people configuring their own experiences – the same distinction reflected in the title of Dan Saffer’s recent book (Designing for Interaction) vis à vis that of Bill Moggridge (Designing Interactions). This may seem like semantic pedantry, mere quibbling, but the difference is crucial: people are already organizers and designers of experience par excellence. Why not let them continue to be?

And this leads us, finally, to the concept not of the seamlessness of designed experience, but of “beautiful seams.”

This term was coined by the late Mark Weiser, a pioneer of ubiquitous computing and the Chief Technologist at what was at the time the Xerox Palo Alto Research Center. Instead of the discourse of smooth, distinction-obliterating, disempowering seamlessness which was then (and is to a significant degree still) dominant in discussions of ubiquitous information processing systems, Weiser wanted to offer users ways to reach into and configure the systems they encountered; ideally, such seams would afford moments of pleasure, revelation and beauty.

Regrettably, Weiser never fully developed this notion, but others have taken it and run with it. And this in turn suggests a valid and a valuable, if relatively minimalist, role for the experience designer: crafting the seams between the distributed components of a product/service, such that they enhance the perception of the whole. This means limiting the ambition of the designer to those aspects of the experience most likely to be definitive, which most require and would best benefit from expert guidance and intervention.

In the long run, providing for high-quality experiences in a deeply networked age means having the humility to know when our efforts are most welcome…and when, as designers, we must let go.

I found that Scrapblog is up and working beautifully! After playing with it briefly, I was impressed. I’d found the tool I’d been looking for!

The Flex-powered interface is intuitive and fluidly responsive…

The vast collection of backgrounds and stickers express a broad diversity of moods and styles and have an Apple-caliber elegance…

You can easily import content from Flickr (and other external sites)…

And the potential for using it with participatory design research methods seems great…

Collage Activities and Mood Boards

Imagine: Instead of printing out dozens of pages of images, which still limits your research participant to whatever you’ve selected, you can open up the entire Flickr universe to the participant to create their collage. Or, if you want the participant to choose from pre-selected images, you can create a Flickr gallery and ask the participant to draw from those.

Remote Participatory Design

The interface is pretty intuitive, so with little explaining, you can now conduct collage exercises with remote research participants. While it’s unfortunately not a collaborative interface (where multiple people can work on the same collage simultaneously and see updates dynamically), it’s easier than constructing and mailing participant a collage kit! (I’d love to see some collaborative functionality built in though.)

Diary Studies

Multiple page “scrapblogs” (which are actually what the site is designed to produce) can easily be created and published both publicly and privately. I can see scrapblogs being used for or supplementing diary studies, allowing participants to tell their experience stories in a fun and creativity-inducing way.

Challenged by an open letter that diabetes patient Amy Tenderich wrote to Steve Jobs, the American experience design consultancy Adaptive Path developed Charmr, an experience design concept to project how insulin pumps and glucose meters might work five years from now.

As reported in CNet News, Charmr is “a prototype for a sleeker, more functional blood glucose monitor and an insulin pump that users can apply directly to their bodies as an adhesive.”

“They researched extensively, interviewing diabetics and consulting with Tenderich, a valuable source of information and a link to the diabetes community.

While the Charmr vaguely resembles an iPod Nano, it has an appeal of its own. The device allows users to monitor the trends of their blood sugar levels, as well as administer insulin via a sweat-proof patch. Not to mention, the device allows for wear on the wrists, or as a keychain or necklace–all of which let the device simply appear to be another mysterious gadget, as opposed to a complex medical apparatus. Furthermore, the Charmr will triple as a USB drive that allows users to view daily trends and patterns of their condition, and other special features.”

The displays on leading insulin pumps today are the size of PDA screens and use a number of hard keys for navigation. Was it even realistic to create an adequate, easy-to-understand interface using a 2 x .75 inch touch-screen half the size of my Nokia N73’s screen?


Dan Saffer and I began the interaction design process by examining the options and screen content in existing devices. Identifying what our participants actually used, we sought out the “essence” of the insulin pump.

The “Ah-ha!” moment for me was recognizing that the interface that most type 1 diabetics today are interacting with is nothing more than a simple syringe.


All there is to this “interface” is:

  1. A way to select the amount of insulin you need (either by dialing it in or by withdrawing the appropriate amount from a vial), and
  2. A way to deliver the insulin (which provides clear feedback that it’s working: seeing the insulin disappearing into your body and the feeling of pressing the plunger makes you feel in control).

The rest of the details are dealt with in the mind.

As one of the barriers to adopting pumps today is perceived complexity, our goal became to create an interface that is no more intimidating than dialing in your insulin needs on a pen. Additionally, the device needed to provide just enough “smarts” to take away true mental burdens (like calculating your insulin dosage using your carb-insulin ratio), while keeping the user in control.

With these principles guiding us, we delved into the interaction design details: What features should the Charmr have? What feature will be used the most (dosing)? Which buttons would be soft (most of them) and which hard buttons we would need (a back button)? What is the minimum button size for a hand-held touch-screen device (many kiosks use 16mm square, whereas the iPhone uses considerably smaller, 9mm square buttons)? Which information should be shown on which screens to support particular tasks?


We also spent a bit of time discussing what kind of imagery would make the best ambient display of status (the mood ring screen). Amy Tenderich told us that one of diabetics’ greatest struggles is with guilt. They look at the numbers and feel guilty all the time. Thus, the ambient display needs to visually represent your status without assigning “moral value” to high or low blood sugar — the way a thermometer might show blue or red; neither is inherently bad.

We considered virtual pets, lava lamps, color abstracts, weather, and simply a personal/family photos theme (because it’s family or a particular goal that often motivates people), and finally concluded that the device should offer multiple themes and allow the user to choose what motivates them.


Finally, I developed a skin for the interaction design, striving to make it compelling and modern, while avoiding both “medical device blue” and the iPhone look and feel. The user could customize both the themes and the skins to their tastes, and perhaps even download more skins and themes online.


With the screen designs as well as a rudimentary industrial design concept completed, we put together an Experience Blueprint (4mb pdf), then it was time to tell the story of the product.

If you’ve been in any bookstore in your lifetime, you’re probably familiar with that most peculiar of book retail locales: the Fantasy & Science Fiction section. This strange and sweaty place is kept separate from the rest of the bookstore so that its residents, the soap-averse fans of Fantasy & Science Fiction novels, can go about their plots and dark rituals without disturbing any of the normal-smelling clientele.

But there’ another very good reason for keeping Fantasy & Science Fiction books segregated. They look really weird. The absolute worst part about every fantasy novel, apart from the writing, is the ludicrous cover art they all seem to have. It’ so bad, that ironically enough in this modern age, it’ still very bad.
