frog’s Creative Director, Scott Jenson, first UI designer at Apple and recent head of UX at Google mobile, recently blogged about smart devices and how that changes the design process. this is relevant to the very real near future of robotics. I’m continuing the zeitgeist sampling here.
Triumph of the Mundane
By Scott Jenson – April 18, 2012
Smart devices require a significant shift in thinking
This blog explores how to design smart devices. But these new devices are just so new and require such new insights, that our quaint, old school notions of UX design are completely blinding us. We are stuck between the classic paradigm of desktop computers, and the futuristic fantasy of smart dust. The world is either fastidious or fantastic. The path ahead is hard to see. Alan Kay said the best way to predict the future is to invent it… but what if we don’t know what we want?
Coffee Maker Syndrome
I’ve long proposed just-in-time interaction as a core approach to smart devices but while presenting on this topic over the past year, it has astounded me that people have such a hard time just thinking about the overall landscape of smart devices. Take for example this tweet:
Overheard at #CES: “I’m pretty sure my coffee maker doesn’t NEED apps.
On the face of it, this makes perfect sense. It seems unlikely you’ll be reading your email on your coffee maker. But this dismissive approach is an example of what Jake Dunagan has called “the crackpot realism of the present”. We are so entrenched in our current reality that we dismiss any exploration of new ideas. By stating that apps on a coffee maker would be silly (which is true), we easily dismiss any discussion of other potential visions of functionality.
When television was first introduced, the earliest programs were literally radio scripts read aloud in front of the camera. Radio had been dominant for decades so broadcasters just coasted into TV without thinking creatively about how to approach the medium differently. As Marshall McLuhan said, “We look at the present through a rearview mirror; we walk backwards into the future.”
Smart devices require three big shifts
Assuming that smart devices require apps is like walking backwards into the future. We don’t need our smart devices to run Microsoft office, we just need to them to, say, log their electrical usage (internal, invisible functionality) or give us quick how-to videos (simple user facing functionality).
If we want to properly discuss how to design smart devices, we must appreciate how they shift away from standard computers in three significant ways: micro functionality, liberated interaction, and a clustered ecosystem.
Shift 1: Micro Functionality
In my last post I discussed a fundamental UX axiom that Value must be greater than Pain. This handy little axiom implies many useful theorems. The most radical is that if pain gets very low, the actual value can also be low. While expensive tablets demand significant functional apps, cheap processing allows for more humble micro functionality. It’s one of the biggest hurdles that people have in discussing smart devices. They are so entrenched in the PC paradigm that they assume every device with a CPU must be bristling with functionality.
However, simple doesn’t equate to useless. For example, whenever I offer up the possibility of a ‘smart toaster’ people often chuckle; it’s the coffee maker syndrome all over. But there are lots of small and even fun things a toaster could do: log it’s electrical usage, offer up an instructional video on how to clean the crumb tray, report any diagnostic errors, call the support line for you, or even tweak it’s ‘toast is done’ sound. All of these are fairly trivial but are still useful if a) the value is genuine and b) the cost of adding the functionality is small. $600 tablets must to do quite a bit but this isn’t true for a $40 toaster.
The biggest impact of micro functionality is in how little real interactive power is required. So often when I talk of using HTML5 as the lingua franca of smart devices, people trot out the ‘it can’t do X’ argument, extolling the superiority of native apps. But micro functionality is so basic and simple that HTML5 is more than adequate: you’ll normally only need to view or change a simple value. Micro functionality only requires micro expressivity.
Shift 2: Liberated Interaction
Remember that Value must be > Pain. Micro functionality requires micro pain to be viable. No one is going to argue with their toaster; this type of functionality has to be quick, fast, and easy. Unfortunately, the trend today is that any device with functionality will usually have a tiny display, tinier buttons, a complex user manual, and a tech support line.
Smart devices need to be liberated from being solely responsible for all interaction. I’ve written previously about just-in-time interaction which allows any smart display (a phone, tablet, TV, interactive goggles, and yes, a laptop) to interact with a smart device. Using a significantly more capable device is so much better than cobbling together a cheap LCD display with fiddly little buttons on the device itself. A generation raised on rich phone interaction will expect, even demand better.
Moving interaction to smart displays also has a huge benefit for manufacturers. The cost of computation will likely be the least of a manufacturer’s concerns. Small displays, buttons, complex instruction manuals, and tech support lines are all very expensive. What if manufacturers could assume that any smart device they built would have free access to a big interactive color screen? Not only that but it would have excellent computing power, smooth animated graphics, a robust programming environment and to top it off a universally accepted consumer interaction model that didn’t require any training? Using these displays would allow enormous cost reductions, not only in parts costs, but in simpler development costs as well.
Shift 3: A Clustered Ecosystem
Once we liberate the interaction from the device, we’ve unlocked its functionality across many locations. Not only can I use my phone in front of my thermostat but also with my TV across the room and with my laptop at work across the city. By liberating functionality from devices, we liberate our ability to use these devices from anywhere. My previous post was called “Mobile Apps must die” not because apps will actually die (they will always have a role) but the shortsighted desire to funnel functionality exclusively through them must stop. If these very simple apps are written in HTML5, they can be used across any device which is very powerful indeed.
It is inevitable that devices will ship with interactivity built in. But as more devices become functional, it’s going to become overwhelming to have each device be it’s own island. The three shifts discussed here: micro functionality, liberated interaction, and a clustered ecosystem all point to a new pattern of thinking: small devices with small functionality that all work together in profound ways. This is a triumph of the mundane; a challenge to our PC soaked way of thinking.
But this new approach requires an open standard that all devices would use to announce their presence and offer their functionality in a universal language like HTML. In many ways we are at the cusp of a new hardware era of discoverability much like the web first had in the 80s.
What’s holding smart devices back is our oh-so-human ability to misunderstand their potential. These three shifts are a big step in understanding what we need to do. Let’s be clear, this is not technically challenging! We just need to understand what we want. Alan Kay is right: we have to invent our future. frog, where I work, is just starting to build simple prototypes to validate these concepts. As they mature, I’ll be sharing more information about them. It’s clear that technology is not the limiting factor, it’s just our desire to imagine a different future.
