At the end of last year I spent some time learning how to create an iOS app using the Augmented Reality tools available in Xcode. Below is a tweet I posted at the time to refresh your memory (well, for those who follow me)
What I have learned from this experience is that AR development is really not too complicated in iOS, many of the intelligent work is done behind the scenes. So to just place an object into an AR scene you really just need to know where in the space around you want to add it and then drop it in. The default template for an iOS AR app already has a “Jet Plane” object and without changing a line of code you get a working app. Here is what it looks like:
From this point all you need to do is define points in 3D space and add text, images and movies.
The example from the Tweet I made follows a process where the app “looks” for objects that match the size of an A4 page with the same contents of one of the images. It then attaches a node of the same dimensions over the top and then plays a movie which matches the photo inside the node. I later added text that sits above the object and moves with it.
Once I made the basic app I saw the possibilities to me of how this could be used at school. I believe this a great template for a AR tour of a school. Meeting the requirements of being a real world problem and solving a problem that affects the community, students could easily come up with their own version of using the app.
Mathematically speaking I also appreciate the complexities in understanding how to place the objects inside the AR space. The technology understands distances and angles perfectly so it become a great activity in reinforcing these concepts.
So over the coming week or so I will be releasing 5 movies that explain the process of creating the App. The best part is that the app works well after covering 2 of them, so it is quick at getting some buy in. The final 3 movies go through the process of adding some polish.
I look forward to seeing other educators and students having a go and seeing what they come up with.
