Augmented Reality is definitely trending up the Hype Cycle in a big way. The past year has seen explosive growth in this nascent field buoyed by the rise of gps-enabled, cloud-aware smart phones. The marketing hype has, of course, been even more resounding, like a wailing chorus of virtual vuvuzelas trumpeting the next great wave of advertising (I couldn't resist). But beneath the hype and the fluff is a thriving community of innovators & designers working to weave this technology into the very fabric of our lives.
As a quick review, augmented reality is a context-aware UI layer rendered over a camera stream or other transparent interface. This is typically mediated by geo-location, orientation, physical markers (those funky UPC-like symbols), and visual recognition. In this manner AR is able to reveal visually the hidden data shadow of our world, like showing you the nearest coffee shops or details about the air quality in your city. The mobile device gets info about where you are and what direction you're facing, goes to the cloud to look up data appropriate for the vicinity, then renders it over the camera stream in a way that updates as you move.
A whole industry has been born around this premise, dragging in images, annotations, and data to overlay on the camera stream of our mobiles. But the really interesting stuff is yet to come. As standardization issues, hardware issues, and numerous UI design challenges sort out in the next couple of years, concurrent with the development of AR-specific devices, our interaction with visualized data will become more and more specialized and appropriate to our individual needs. The clutter of markups that currently plagues many AR apps will be attenuated by algorithms that know our interests and affinities and block out the elements we wish to avoid. Just like Amazon makes recommendations based on your click & purchase history, AR apps will screen out the noise and provide us only with the data we need.
When paired with the massive deployment of embedded sensors AR becomes a lightweight visualization layer for interfacing with the instrumented world. Civic workers could see underground cables and pipelines. Homeowners could see real-time energy & network use. Police and early responders could post visual warnings cordoning streets and alerting to hazards. Ecologists could determine water & air quality at-a-glance. Ecosystems begin to have a voice, communicating soil contamination to observers. Public facilities like park benches, utility poles, and street signs could hold annotations & links created by community members, made public or gated by in-group permissions. Geographic social annotations could mark up our cities with tags and content. Virtual worlds might break out of the box and overlay on the physical plane. The environment suddenly becomes much richer - and potentially much nosier - with a flood of information. Augmented reality promises to exteriorize the cloud, drawing it out across the world canvas and making visible our social fabric. But it doesn't promise to mediate or regulate that content.
We risk myopia, disconnection, visual occlusion, fragmented realities, reinforced tribalism. Consider the seemingly-inevitable future where eyewear mediates a cloud-aware augmented interface with the world. Perhaps you opt to obscure ethnicities or anyone not connected to the net. Ghettos look much nicer when painted over with high-res colors and dancing sprites. The world you experience is really only shared by the other people running your default layer set. Maybe you see paycheck information or health records or political affinities of those you pass, measuring up the once-private lives of your community. Perhaps the most popular layers are hacked to display swastikas or porn or spam swarms or simply to black out your view in the middle of the morning commute. How does the layered world enable crime, gang affinities, and political or religious extremism? What inevitable inequities might arise between those able to purchase such access and those condemned to the dark poverty of quiet disconnection? Do the wealthy become even more enhanced & capable compared to the underclass? And what are the risks of getting lost in the virtual glitz? Are there considerations for how these augmented realities will bring us closer to the natural world in which we're embedded? And just what is "real" or "natural" anymore?
As connected social computing devices get smaller & smaller and nearer & nearer to us, the weight of the cloud gets lighter. We carry around immense computational power and almost immediate access to the global repository of information. The mobile phone will eventually pair with head's-up eyewear displays just as more and more people avoid catastrophic disease & injury through the aid of embedded brain-computer interfaces. As computation moves next to and into our bodies, the cloud is breaking out of the screen and washing onto our world. We grow more augmented with computation while our environment is getting smarter and more aware and increasingly able to communicate with us. It may very well be that in 5, 10, 20 years the world is a much more visual, dynamic, and communicative place than we can even imagine.
