Surround sound? That's old technology. How about surround vision?
The folks at the MIT Media Lab have developed a new system called surround vision that can let you follow objects outside of your regular TV screen by viewing them on smartphones and handheld Internet devices. Imagine you're watching a movie on your regular TV, and a car drives off the screen. You could follow and view that car as it drives away by looking at and pointing your smartphone or tablet in its direction.
The person leading this promising new project is Santiago Alfaro, a graduate student at the lab. To kick-start his testing, Alfaro attached a magnetometer to an existing handheld device. A type of digital compass, magnetometers are already used in smartphones like the iPhone to detect the direction the device is pointing. He then created the necessary software to sync the magnetometer with other sensors on the device.
After outfitting the handheld with motion sensors, Alfaro shot video on campus from three different angles--center, left, and right. Watching the TV screen straight on played video from the center. But by pointing the handheld to the left or right, Alfaro was able to view the footage shot from both side angles.
As a further test of the technology, Alfaro took advantage of the alternate takes found on many DVDs. He created a demo that let him switch between the final footage and the alternate takes and angles by changing the direction of the handheld device.… Read more
