You are going to need a speed sensor of some kind and some connectivity to your computer (ANT+ dongle) if you want to do anything like that Virtual Training program. The strava/cateye connection isn't going to work if you are not actually moving. You might want a heart rate monitor too. You don't *need* anything except a fan and something to look at (TV, whatever) but training software makes the time go by a lot faster and can help you tune your efforts towards being good training.
TrainerRoad, Zwift and Sufferfest are all things you might be interested in. I don't every hear of anyone using Virtual Training, not that I know anything about it, it's just not popular. Zwift and TrainerRoad are the most popular right now, for good reason. Zwift is a virtual reality racing game, it's really immersive and fun, and you can really get a great workout without getting bored, which is the biggest enemy of trainer use.
