More than downloads this month. Conventional computers now sport touchscreens and otherwise blur the lines between device types — and between mobile and desktop operating systems. Mobile and touch are the new computing normal , but there is a lot of myth, rumor, error, bias, and out-of-date information on how portable touchscreens are used.
Touch Design for Mobile Interfaces presents and shares real information on hardware, people, interactions, and environments. Steven Hoober has studied how people really touch and hold phones and tablets, as well as seeing it firsthand over twenty years designing products for mobile phones, tablets, kiosks, and computers. Written by Steven Hoober. Cover design by Espen Brunborg. Shipping starting in early January.
This book is for digital-first designers working on mobile or touchscreen products. If you want to design better for mobile, or you need data to back up your decisions, this book is evidence-based, specific, and full of actionable information.
If you want to move from desktop design to mobile, the book provides a path for you to reconsider design decisions for touch and mobility. There are benefits too for product designers, managers, and analysts, as well as developers and engineers on mobile touchscreen products.
How do people really use their mobile devices? And how can we design better mobile interfaces based on that knowledge? The first chapter describes different devices in the context of their unique attributes of portability, connectivity, and awareness. Chapter 2 reviews the evolution of direct screen interaction dating back to the s, and the development of commercialized touch since the s.

Your link to middle school life science does not work. Your email address will not be published. Imagine that your purpose is not to replicate, or even to survive, but to gather information.
I can imagine that easily. It is in fact a much simpler impersonation than the kind I'm usually called on to perform. I coast through the abyss on the colder side of Neptune's orbit. Most of the time I exist only as an absence, to any observer on the visible spectrum: a moving, asymmetrical silhouette blocking the stars. But occasionally, during my slow endless spin, I glint with dim hints of reflected starlight. If you catch me in those moments you might infer something of my true nature: a segmented creature with foil skin, bristling with joints and dishes and spindly antennae.
Here and there a whisper of accumulated frost clings to a joint or seam, some frozen wisp of gas encountered in Jupiter space perhaps. Now, a breath away from Absolute Zero, they might shatter at a photon's touch. My heart is warm, at least. A tiny nuclear fire burns in my thorax, leaves me indifferent to the cold outside.
It won't go out for a thousand years, barring some catastrophic accident; for a thousand years, I will listen for faint voices from Mission Control and do everything they tell me to. So far they have told me to study comets. Every instruction I have ever received has been a precise and unambiguous elaboration on that one overriding reason for my existence. Which is why these latest instructions are so puzzling, for they make no sense at all. The frequency is wrong.
The signal strength is wrong. I cannot even understand the handshaking protocols. I request clarification. The response arrives almost a thousand minutes later, and it is an unprecedented mix of orders and requests for information. I answer as best I can: yes, this is the bearing at which signal strength was greatest. No, it is not the usual bearing for Mission Control. Yes, I can retransmit: here it is, all over again.
Yes, I will go into standby mode. I await further instructions. They arrive minutes later, and they tell me to stop studying comets immediately. Upon encountering any transmission resembling the one which confused me, I am to fix upon the bearing of maximal signal strength and derive a series of parameter values. I am also instructed to retransmit the signal to Mission Control.
I do as I'm told. For a long time I hear nothing, but I am infinitely patient and incapable of boredom. Eventually a fleeting, familiar signal brushes against my afferent array. I reacquire and track it to source, which I am well-equipped to describe: a trans-Neptunian comet in the Kuiper Belt, approximately two hundred kilometers in diameter. It is sweeping a cm tightbeam radio wave across the heavens with a periodicity of 4.
This beam does not intersect Mission Control's coordinates at any point. It appears to be directed at a different target entirely. It takes much longer than usual for Mission Control to respond to this information. When it does, it tells me to change course. Mission Control informs me that henceforth my new destination is to be referred to as Burns-Caulfield.
Given current fuel and inertial constraints I will not reach it in less than thirty-nine years. I am to watch nothing else in the meantime. I'd been liaising for a team at the Kurzweil Institute, a fractured group of cutting-edge savants convinced they were on the verge of solving the quantum-glial paradox. That particular log-jam had stalled AI for decades; once broken, the experts promised we'd be eighteen months away from the first personality upload and only two years from reliable Human-consciousness emulation in a software environment.
It would spell the end of corporeal history, usher in a Singularity that had been waiting impatiently in the wings for nigh on fifty years. Two months after Firefall, the Institute cancelled my contract.
I was actually surprised it had taken them so long. It had cost us so much, this overnight inversion of global priorities, these breakneck measures making up for lost initiative.
Not even our shiny new post-scarcity economy could withstand such a seismic shift without lurching towards bankruptcy.
Installations in deep space, long since imagined secure by virtue of their remoteness, were suddenly vulnerable for exactly the same reason. Lagrange habitats had to be refitted for defense against an unknown enemy. Commercial ships on the Martian Loop were conscripted, weaponised, and reassigned; some secured the high ground over Mars while others fell sunward to guard the Icarus Array.
It didn't matter that the Fireflies hadn't fired a shot at any of these targets. We simply couldn't afford the risk. We were all in it together, of course, desperate to regain some hypothetical upper hand by any means necessary. Kings and corporations scribbled IOUs on the backs of napkins and promised to sort everything out once the heat was off. In the meantime, the prospect of Utopia in two years took a back seat to the shadow of Armageddon reaching back from next Tuesday.
The Kurzweil Institute, like everyone else, suddenly had other things to worry about. So I returned to my apartment, split a bulb of Glenfiddich, and arrayed virtual windows like daisy petals in my head. Everyone Icons debated on all sides, serving up leftovers two weeks past their expiry date:.
Disgraceful breakdown of global security. No harm done. Comsats annihilated. Thousands dead. Random collisions. Accidental deaths. We should have seen them coming. Deep space. Inverse square. Do the math. They were stealthed! We were raped! Jesus Christ. They just took our picture. Why the silence? Moon's fine. Mars's fine. Where are they? Why haven't they made contact?
Nothing's touched the O'Neills. Technology Implies Belligerence! Are they coming back? Nothing attacked us. Nothing invaded. So far. But where are they?
Jim Moore Voice Only. The text window blossomed directly in my line of sight, eclipsing the debate. I read it twice. I tried to remember the last time he'd called from the field, and couldn't. I muted the other windows. Still wondering whether we should be celebrating or crapping our pants.
He didn't answer immediately. They're not telling us anything at ground level. It was a rhetorical request. His silence was hardly necessary to make the point. Icarus's fine. He seemed to be weighing his words. There's no particle trail as long as it stays offstream, and it would be buried in solar glare unless someone knew where to search. It was my turn to fall silent. This conversation felt suddenly wrong. Because when my father went on the job, he went dark. He never called his family.
Because even when my father came off the job, he never talked about it. It wouldn't matter whether the Icarus Array was still online or whether it had been shredded and thrown into the sun like a thousand kilometers of torn origami; he wouldn't tell either tale unless an official announcement had been made.
Icarus was overdue for a visit anyway. You don't swap out your whole grid without at least dropping in and kicking the new tires first. Nearly three seconds to respond. Isn't this a security breach?
Radio bounced back and forth. I wanted very much for them to pick someone else. But he'd seen it coming, and preempted me before my words could cross the distance: "It's not a slap at your abilities and you know it. You're simply the most qualified, and the work is vital. He wouldn't want to keep me away from some theoretical gig in a WestHem lab.
They found something. From the Kuiper. We traced the bearing. The encryption seems similar, but we can't even be sure of that. All we have is the location. We'd never gone to the Kuiper before. It had been decades since we'd even sent robots. Not that we lacked the capacity.
We just hadn't bothered; everything we needed was so much closer to home. The Interplanetary Age had stagnated at the asteroids. But now something lurked at the furthest edge of our backyard, calling into the void. Maybe it was talking to some other solar system. Maybe it was talking to something closer, something en route. But we can't wait for them to report back. The follow-up's been fast-tracked; updates can be sent en route.
He gave me a few extra seconds to digest that. When I still didn't speak, he said, "You have to understand. Our only edge is that as far as we know, Burns-Caulfield doesn't know we're on to it. We have to get as much as we can in whatever window of opportunity that grants us. But Burns-Caulfield had hidden itself. Burns-Caulfield might not welcome a forced introduction. The timelag seemed to say Mars.
You won't. He didn't have to answer. I didn't have to ask. At these kind of stakes, mission-critical elements didn't get the luxury of choice. Both can be subverted with the right neurochemical keys. We let the vacuum between us speak for a while. In a second. I just wanted to give you the heads-up. Where are you? Are you coming back?
This is what my father could not unmake. This is what I am:. I am the bridge between the bleeding edge and the dead center. I stand between the Wizard of Oz and the man behind the curtain. I am the curtain. I am not an entirely new breed. My roots reach back to the dawn of civilization but those precursors served a different function, a less honorable one. They only greased the wheels of social stability; they would sugarcoat unpleasant truths, or inflate imaginary bogeymen for political expedience.
They were vital enough in their way. Not even the most heavily-armed police state can exert brute force on all of its citizens all of the time. Meme management is so much subtler; the rose-tinted refraction of perceived reality, the contagious fear of threatening alternatives.
There have always been those tasked with the rotation of informational topologies, but throughout most of history they had little to do with increasing its clarity.
The new Millennium changed all that. We've surpassed ourselves now, we're exploring terrain beyond the limits of merely human understanding.
Sometimes its contours, even in conventional space, are just too intricate for our brains to track; other times its very axes extend into dimensions inconceivable to minds built to fuck and fight on some prehistoric grassland. So many things constrain us, from so many directions. The most altruistic and sustainable philosophies fail before the brute brain-stem imperative of self-interest. Subtle and elegant equations predict the behavior of the quantum world, but none can explain it.
After four thousand years we can't even prove that reality exists beyond the mind of the first-person dreamer. We have such need of intellects greater than our own.
But we're not very good at building them. The forced matings of minds and electrons succeed and fail with equal spectacle. Our hybrids become as brilliant as savants, and as autistic. We graft people to prosthetics, make their overloaded motor strips juggle meat and machinery, and shake our heads when their fingers twitch and their tongues stutter. And when your surpassing creations find the answers you asked for, you can't understand their analysis and you can't verify their answers.
You hire people like me; the crossbred progeny of profilers and proof assistants and information theorists. In formal settings you'd call me Synthesist. On the street you call me jargonaut or poppy.
If you're one of those savants whose hard-won truths are being bastardized and lobotomized for powerful know-nothings interested only in market share, you might call me a mole or a chaperone. If you're Isaac Szpindel you'd call me commissar , and while the jibe would be a friendly one, it would also be more than that. I've never convinced myself that we made the right choice.
I can cite the usual justifications in my sleep, talk endlessly about the rotational topology of information and the irrelevance of semantic comprehension. But after all the words, I'm still not sure. I don't know if anyone else is, either. Maybe it's just some grand consensual con, marks and players all in league. We won't admit that our creations are beyond us; they may speak in tongues, but our priests can read those signs.
Gods leave their algorithms carved into the mountainside but it's just li'l ol' me bringing the tablets down to the masses, and I don't threaten anyone. Maybe the Singularity happened years ago. We just don't want to admit we were left behind. Occasional demons too. The Third Wave, they called us. All in the same boat, driving into the long dark courtesy of a bleeding-edge prototype crash-graduated from the simulators a full eighteen months ahead of schedule.
In a less fearful economy, such violence to the timetable would have bankrupted four countries and fifteen multicorps. The first two waves came out of the gate in even more of a hurry. I didn't find out what had happened to them until thirty minutes before the briefing, when Sarasti released the telemetry into ConSensus. Then I opened wide; experience flooded up my inlays and spilled across my parietal cortex in glorious high-density fast forward.
Even now I can bring those data back, fresh as the day they were recorded. I'm there. I'm them. I am unmanned. I am disposable. I am souped-up and stripped-down, a telematter drive with a couple of cameras bolted to the front end, pushing gees that would turn meat to jelly.
I sprint joyously toward the darkness, my twin brother a stereoscopic hundred klicks to starboard, dual streams of backspat pions boosting us to relativity before poor old Theseus had even crawled past Mars.
But now, six billion kilometers to stern, Mission Control turns off the tap and leaves us coasting. The comet swells in our sights, a frozen enigma sweeping its signal across the sky like a lighthouse beam.
We bring rudimentary senses to bear and stare it down on a thousand wavelengths. We've lived for this moment. We see an erratic wobble that speaks of recent collisions. We see an astronomical impossibility: a comet with a heart of refined iron. Burns-Caufield sings as we glide past. Not to us; it ignores our passage as it ignored our approach. It sings to someone else entirely.
Perhaps we'll meet that audience some day. Perhaps they're waiting in the desolate wastelands ahead of us. Mission Control flips us onto our backs, keeps us fixed on target past any realistic hope of acquisition. They send last-ditch instructions, squeeze our fading signals for every last bit among the static.
I can sense their frustration, their reluctance to let us go; once or twice, we're even asked if some judicious mix of thrust and gravity might let us linger here a bit longer. But deceleration is for pansies. We're headed for the stars. Bye, Burnsie. Bye, Mission Control. Bye, Sol. See you at heat death. Warily, we close on target. We are weighed down by payloads which make us virtually omniscient.
We see on every wavelength, from radio to string. Our autonomous microprobes measure everything our masters anticipated; tiny onboard assembly lines can build tools from the atoms up, to assess the things they did not.
Atoms, scavenged from where we are, join with ions beamed from where we were: thrust and materiel accumulate in our bellies. This extra mass has slowed us, but midpoint braking maneuvers have slowed us even more. The last half of this journey has been a constant fight against momentum from the first.
It is not an efficient way to travel. In less-hurried times we would have built early to some optimal speed, perhaps slung around a convenient planet for a little extra oomph , coasted most of the way.
But time is pressing, so we burn at both ends. We must reach our destination; we cannot afford to pass it by, cannot afford the kamikaze exuberance of the first wave.
They merely glimpsed the lay of the land. We must map it down to the motes. We must be more responsible. Now, slowing towards orbit, we see everything they saw and more. We see the scabs, and the impossible iron core. We hear the singing. And there, just beneath the comet's frozen surface, we see structure : an infiltration of architecture into geology. We are not yet close enough to squint, and radar is too long in the tooth for fine detail.
But we are smart, and there are three of us, widely separated in space. Burns-Caulfield stops singing the moment we put our plan into action. In the next instant I go blind. It's a temporary aberration, a reflexive amping of filters to compensate for the overload. My arrays are back online in seconds, diagnostics green within and without. I reach out to the others, confirm identical experiences, identical recoveries. We are all still fully functional, unless the sudden increase in ambient ion density is some kind of sensory artefact.
We are ready to continue our investigation of Burns-Caulfield. The only real problem is that Burns-Caulfield seems to have disappeared Let superfluous deckhands weigh down other ships, if the nonAscendent hordes needed to attach some pretense of usefulness to their lives. Let them infest vessels driven only by commercial priorities. The only reason we were here was because nobody had yet optimized software for First Contact.
Bound past the edge of the solar system, already freighted with the fate of the world, Theseus wasted no mass on self-esteem. So here we were, rehydrated and squeaky-clean: Isaac Szpindel, to study the aliens.
