In this week students learned about adding gestures to their apps. They were walked through an example of creating gestures. After that, they took what they learned and added these features into their existing augmented reality app. Their overlay can now pinch to zoom, rotate, and move to anywhere on the screen you want to position it. They can also swipe to change the image out. Not only did they learn about gestures but they had a great learning experience by cycling through an array of data.
To get the point across about arrays, I found poker chips to be the most effective item to use. I would line up the chips in a row and have them iterate through the chips until the end. The students could see the issue with calling a ++ and getting an item that did not exist. With the poker chips they could physically see where their "if then" statements needed to be checking.
Overall it was a great lesson
