Josh W. Showed us how he is using his iPad to hover over an image of a math problem to trigger a tutorial/coaching video on how to do the math problem.
So- he had a math problem that he had to explain several times...so he created a homework support video the iPad app Explain Everything .
Then, he opened Aurasma and uploaded the video to his library. He hovered the camera over the image he wanted to trigger and positioned the Explain Everything video on that.
Make sure to ask Josh for a demo!
