Yeah dogs learn really fast that what's happening on TV is not real, they will from then on just ignore it since it is irrelevant to them.

However I assume all that is needed for them to start interacting is some relevant feedback. Example: First train the dog to have a positive association with a sound, then show them that this sound is produced if they interact with the TV.

In the article they do this, but go one step further, the game dispenses treats if they are correct. I'm sure a dog will learn the game easily once you clear the initial hurdle.
