I started with the idea of using AR markers by placing them on the side of the page and having the drawing projected onto each page but then I decided that I really want to focus on creating the feeling of each of the drawings coming to life, so I was determined to find a way to use my drawing itself as the marker. Through research and trial and error, I finally got it working properly. I tried out different things and learnt that AR markers actually don’t need to be in square form, only the edge needs to be a square. So I inserted the final drawing marker into the data folder and changed the code, edge percentage, and positioning, and size. I used example AR code that displayed a cube on top of the marker, and changed the code so as to have a video file play on top of the marker.

However I need to now test this out with a webcam and projector to see if it works to have a full drawing animation projected on top of the drawing or if I need to create a different video file with only the moving elements to be projected. I plan to include around 5 drawings and have them on different pages of a hard paper book to avoid bending of the paper, which would affect the marker detection and projection.
