A month after his death, the book of Jobs has almost closed. His legacy has been described in countless obituaries, features, and blog posts, with Walter Issacson’s well-timed biography, Steve Jobs, filling in the more obscure details. Many of these tributes and histories have highlighted the enormous contribution Jobs made not only to the technology we buy, but how we interact with those devices. Of the pioneering products that Jobs either invented or midwifed into existence, one seems to have accomplished this most resolutely: the iPhone. Jobs may have put it best, during the smartphone's unveiling in 2007: “We are all born with the ultimate pointing device—our fingers—and iPhone uses them to create the most revolutionary user interface since the mouse.”
When the iPhone arrived in 2007, it was a revelation, redefining the phone and the computer in one deft swipe. With its iconic, monolithic design and touch-sensitive interface, the iPhone was science fiction made real—the beginning of a new era of gadget lust and device convergence. It was ridiculously popular, as well, dwarfing the sales of any other Apple product, and selling as many as 100 million to date. But in the past four years, the iPhone has created its own, dubious legacy. Its touchscreen transformed the way we interact with technology, and created a new industry standard for gadget design. While the multitouch capacitive display was the perfect interface for a smartphone—folding the functions of a mouse, keyboard, and desktop into a phone, without cramping the display or adding rows of buttons—its broader influence throughout the world of consumer electronics has been a minor disaster.
Steve Jobs didn’t invent touchscreens, nor did some faceless Apple engineer. The first prototypes showed up in the 1960s, a decade before Jobs and Steve Wozniak founded their company. The iPhone wasn’t even the first application of the multitouch technology. It simply made touchscreens irresistible, with an intuitive operating system that replaced the analog, button-studded face of other cellphones with a shape-shifting, digital playpen. Before the iPhone, touchscreens were exotic. Now they are everywhere—in cars, on refrigerators, beside CNN anchors, and have shrunk down to just over a 1-inch square for the latest iteration of the iPod Nano. What has been described as one of Jobs' greatest achievements spread from one class of gadget to another; huddled masses of single-function buttons converted, one by one, into powerful, touch-sensitive windows of infinite utility.
Grafting the iPhone's clever, customizable interface onto other products sounds like a universal win. Then again, try using that touchscreen Nano. With the proper dance of carefully aimed taps and flicks, it can do more than any Nano before it. But when it comes to what iPods were built to do—play audio files—the Nano has devolved. The physical playback buttons have vanished. As one Macword reviewer complained when the player was released in 2010, it's harder than ever to pause or play a track: “You must pull out the Nano so you can see its screen, then wake up the iPod, then navigate to the appropriate screen.” What might have been a one-step operation on the pre-2010 Nano now requires a sequence of three or four actions. And aside from adjusting the volume, the Nano can’t really be operated blind, with one hand in your bag or pocket. A software update this past winter allows for customizing the wake button to perform one function when double-clicked, such as skipping or pausing. It's an improvement, but not a true fix. Like the iPhone, it still demands your full attention: Both eyes and, in most cases, both hands.
Admittedly, this is a minor detail. But that’s where interface design lives and dies, in the tiny time-savings associated with the simplest operations. An outstanding interface separates the products you love from the ones you simply use. In the Nano’s case, the touchscreen works. There’s nothing broken about it. But it’s clumsy and ill-conceived, given the uses for which it's supposedly designed. To put a touchscreen on a Nano presumes that a touchscreen can be a universal interface, and that all devices aspire to do all things. But people don’t buy a Nano because they want a mini-iPhone or a micro-iPad. They want something they can shove in their pocket or clip to their shorts when they take a walk or go for a run, a device for playing music on the move. In those scenarios, a touchscreen doesn't help at all.
The ubiquity of touchscreens has been even worse for other sorts of devices. It’s one thing to have to slow or stop mid-jog, and fiddle with an iPod so it performs its basic functions. It’s another to take your eyes from the road, and poke at the touchscreen in your car’s center console, tapping through menus, holding and dragging scroll bars, to access a specific radio station or playlist. That’s the state of the art in automotive infotainment, as the industry abandons decades of experience with analog controls for the sake of embedded, iPhone-like touchscreens. The allure, as always, is the infinite. Why should the designers at Toyota or Volkswagen commit to a row of radio station preset buttons, when that real estate could multitask instead? A smooth touchscreen can absorb the digital stand-ins for those old-fashioned buttons whenever it's convenient, so you can order movie tickets or make dinner reservations instead.
