Choosing developement technology: game engines,wpf or html5?

I am working on a project, where we want to use a camera to detect people and create an interactive experience like a touchscreen for advertisement. The goal is to have some cool and fascinating interactive animation and graphics(mostly 2D), but not a game.

We are using c# for the back end and are considering the following options: monogame, Ogre, WPF, unity, UDK, HTML5, webGL. which one do you think is the best option for us? Thanks,
