AR interaction

Hi everyone! I'm creating a simple app for a Science Fair in school. I'm making a AR app where I use a map and it draws a rute in the map by using an animation through EasyAR package. Well, my issue is that I wanna make rutes touchables and set active or inactive an object to show as well. I wonder how could I implement that?......I was thinking in "Touch" but I really have no idea if it may works
