"The Next Generation of Play - Vision-Based Augmented Reality"
by Dr. Blair MacIntyre, Director of Qualcomm Augmented Reality Game Studio at Georgia Tech, and co-Founder of Aura Interactive, LLC

What do you get when you combine smartphones, mobile gaming, 20 years of research in augmented reality (AR), and Qualcomm's vision-based platform? We are beginning to answer this question through a research and education collaboration between my colleagues and students here at Georgia Tech, and Professor Tony Tseng and his students at the Savannah College of Art and Design's Atlanta campus.

In AR, graphics (and sound) are superimposed on the physical world that a user sees (and hears) through a camera. Think of the first-down line on the field in a televised football games, or the flags in the swimming pool when you watch the Olympics. A live spectator can't see those graphics, but a television viewer can see them because the virtual content is added to the live video stream before it reaches your TV, and then your eye. Now imagine that someday, similar graphical augmentation will be possible using your mobile phone.

Since the late 1990s, my research group at Georgia Tech, the Augmented Environments Lab, has been researching ways to enhance the computing experience by putting graphics and sound into the world around the user. We've experimented with applications in art, maintenance and education that mix images and information with the physical world. Early on, we used desktop computers and head-worn displays, connected to expensive head-tracking hardware. As mobile phone technology began to improve over the past few years, we turned our attention to commodity hardware instead, and began our collaboration with Prof. Tseng and his students at SCAD to explore the potential of AR games. Over the past year, we've expanded by forming the Qualcomm Augmented Reality (AR) Game Studio at Georgia Tech. The collaboration provides the faculty and students in our collaborative Game Studio access to both the high-end hardware and the vision-based AR technology that will enable us to push the envelope in game development.

Augmented Reality Today

There is no shortage of ideas on how to leverage AR these days. The examples from televised sports show what happens when you tie graphics to the physical world in the context of broadcast TV; many advertisers are using webcam-based AR to create little toys and advertising gimmicks; our vision of AR is that it will form the foundation for the next generation of play. All the right things are falling into place for AR to move out of the research lab and into common use:

  • small, powerful mobile devices are becoming pervasive
  • high-end gaming engines for creating rich graphics are available for these devices
  • designers and developers with remarkable creativity are hungry for a new place to take their users


In the Qualcomm AR Game Studio at Georgia Tech, our dream is to discover new forms of play, in the same way that advances in computing technology have enabled advances in gaming over the past decades. Just as online games, the Wii and now the Kinect have each created the possibility for new play experiences, when graphics appear to be in the world around us, games can engage users in bigger ways. Based on our experiences, I firmly believe that vision-based AR is essential to building games that give players the sense that the graphics really are in the physical world, and will therefore let designers create experiences that keep players coming back to play and socialize, and have deeper and more engaging experiences.

I'm a strong advocate of vision-based AR because I believe that if we want users to behave as if the graphics are in the physical world, the graphics need to behave as if they really are in the world. That's not easy, and doesn't happen with most of today's AR apps because they rely on the built-in sensors on mobile phones, such as the GPS and compass, and those devices aren't accurate enough to let the app display the graphics convincingly. For instance, if your app is meant to display a troop of zombies limping down the street toward you, the best these sensor-based apps can do is have the zombies bounce around in front of you or seem to float a couple of feet off the sidewalk. However, with vision-based AR, there is the potential for more accurate detection and tracking, so an app might be able to create the impression that the zombies were actually coming down the street at you.

Mattel used Qualcomm's augmented reality SDK to bring the classic Rock 'Em Sock 'Em Robots game to life in a completely new way.

Keeping the zombies firmly planted in the physical world is where vision-based AR and Qualcomm enter. Even before starting up the Qualcomm AR Game Studio at Georgia Tech, my company, Aura Interactive, collaborated with Mattel and used the Qualcomm AR software development kit (SDK) to create a proof-of-concept Rock 'Em Sock 'Em Robots AR game.

What is Vision-based AR?

To create an AR experience where the graphics appear to be out in the physical world, the device needs to know where it is relative to the objects around it in order to draw graphics in the proper location. For many early mobile AR applications, developers relied on built-in GPS and compass sensors to solve this problem. For example, many AR applications use GPS and compass data to allow the user to visualize the nearest coffee shop by pointing a device down the street. While appropriate for some information retrieval applications, this approach is not accurate enough to align graphics with underlying objects in the physical world. The result is the reviews for the coffee shop you are pointing at show up on top of the burger joint down the street. This is due to inherent limitations of GPS and digital compass technology. At the Qualcomm AR Game Studio, we are using Qualcomm's AR platform, which includes the vision-based AR SDK, to create games that align graphics tightly with the physical world.
Our relationship with Qualcomm is playing a big role in taking our vision of social AR games to the next level, and if you're interested in creating AR experiences that bring your users into the world of AR, I encourage you to take advantage of some of these opportunities:

  • The Qualcomm Augmented Reality SDK is for developers of vision-based AR apps, initially for Android (v.2.1 and up) with high-end detection and tracking, and a rich set of features for development. My company used this SDK for the Rock 'Em Sock 'Em prototype.
  • Qualcomm has also released the AR Extension for Unity, with AR-specific functionality and options that enhance Unity Technologies' award-winning game development environment. With the extension, you can develop rich interactive experiences in less time. We're using Unity3D and Qualcomm's AR extension in the AR Game Studio at Georgia Tech.
  • Last but not least, Qualcomm is sponsoring the Augmented Reality Application Developer Challenge and offering a total of $200,000 in cash prizes for the most effective, entertaining and functional new application products built using the Qualcomm AR SDK. I'm happy to be serving as a judge for the developer challenge, and look forward to seeing what creative people come up with to shake loose the next wave of AR apps.

The Future of AR

Researchers have long talked about applications for gaming, media, industry, military and medicine, but AR can go far beyond these. I imagine that at some point, you'll be wearing a head-mounted display that looks like a cool pair of sunglasses. You'll be walking down the street and there will be information everywhere: updates from friends, advertisements, games, serious applications and some new form of social media that has yet to be invented. All of this will be tightly integrated onto your view of the physical world around you in a way that won't be distracting or get in your way.

But that's just where my imagination goes. We're all looking forward to seeing where you take AR, so download the SDK, enter the Developer Challenge and join us on the journey.
