Researchers are pulling graphics out of the digital world and integrating them into real-world environments. This technology, known as Augmented Reality (AR), blurs the line between what’s real and what’s computer-generated by enhancing what we see, hear, feel and smell. Augmented reality adds graphics, sounds, haptic feedback and smell to the natural world as it exists. Everyone can now benefit from the ability to place computer-generated graphics in their field of vision with devices and applications already existing on smartphones.
Imagine yourself walking or driving down the street. With AR displays, informative graphics will appear in your field of view, and audio will coincide with whatever you see. These enhancements will be refreshed continually to reflect the movements of your head.
The Bleeding Edge
Some of the most exciting augmented-reality work is Pattie Maes and Pranav Mistry’s SixthSense that relies on some basic components strung together in a lanyard like apparatus that the user wears around his neck.
These components are : Camera, small projector, smartphone and a mirror. The user wears four colored caps on the fingers used to manipulate the images that the projector emits. SixthSense uses these simple, off-the-shelf components and turns any surface into an interactive screen. It works by using the camera and mirror to examine the surrounding world, feeding that image to the phone (which processes the image, gathers GPS coordinates and pulls data from the Internet), and then projecting information from the projector onto the surface in front of the user, whether it’s a wrist, a wall, or even a person.
Because the user is wearing the camera on his chest, SixthSense will augment whatever he looks at; for example, if he picks up a box of cereal in a store, SixthSense can find & project onto the box its ingredients, price, nutritional value — even reviews! The wearer can then use his fingers to interact with the projected image and learn more. SixthSense can also recognize complex gestures. Eg. drawing a circle on your wrist will project a watch with the current time.
The Cutting Edge
‘Primitive’ versions of augmented reality are already here on some smartphones like the iPhone and Android. Underlying most of these applications are a phone’s GPS and compass; by knowing where you are, these applications can make sure to offer information relevant to you.
Layar uses the phone’s camera and GPS capabilities to gather information about the surrounding area. It then overlays information about restaurants and other establishments in the area on the screen. Pointing the phone at a building will tell you if companies in that building are hiring, or it might be able to find photos of the building on Flickr or locate its history on Wikipedia.
Yelp’s augmented-reality component, Monocle, uses the phone’s GPS and compass to display information about local restaurants, including ratings and reviews, on the screen. You can touch one of the listings to find out more about a particular restaurant.
Le Bar Guide will assist you in finding the nearest watering hole, give ratings and even point you to a taxi within stumbling distance. It’s accurate to 20 feet.
WorkSnug, an iPhone app that finds digital nomads a place to lay their weary laptop. It identifies Wi-Fi hotspots and potential workplaces — from coffee shops to professional rent-a-desk office spaces — with user reviews encompassing power provision, atmosphere, noise levels and even the quality of the coffee.
Pocket Universe will spell out the stars, planets and constellations for you. Needing no connectivity, this clever app contains data on 10,000 stars, 88 constellations and lunar phases, while the “tonight’s sky” feature shows meteor showers and visible planets based on your location.
DishPointer is designed for satellite installers or mobile broadcasters to hold their phones up to the sky and get a virtual overlay of their nearest satellites to know which way to point the darn dish.
AugMeasure which lets you gauge short distances using on your iPhone’s camera.
Theodolite lets you know what axis is bisecting your Northerly inclination and at what altitude. It overlays such data over your camera’s image and even lets you snap the screenshot for posterity.
Car Finder creates a visible marker showing the car, its distance away and the direction in which to head.
The Wikitude World Browser AR app displays data and other points of interest by overlaying information on the real-time camera view.
Acrossair Nearest Tube App will pin-point where the nearest subway or light rail stations are for the London Tube, Paris Metro, Tokyo Subway, Barcelona Metro, San Francisco Transit, Madrid Metro, and New York Subways.
Acrossair Twitter App will display all the tweets around you in 360 degrees of Augmented Reality view, with the distances and photos of the people tweeting around you.
Those were some of Augmented Reality applications/products already available for anyone to experience it today.
