I had a dog whom I was never able to get to identify motion in a LED TV. So how would this work? Dogs need environmental stimuli. Smells and moving objects.
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.
