This application is something that I was fortunate enough to beta test. It was created by the good folks at Eduglasses.
This is how it works. The developers have created their own library or augmented reality triggers that you can either print out or have ready on the computer screen. You say “okay glass Edureal” and this command takes you into the app. Then you will scan for content. The 2 dimensional triggers, when scanned with Google Glass will lead you to 3 dimensional multimedia content. I love the idea of using augmented reality to create more personalized learning experiences for my students.
