the biggest innovations in the interaction design will happen through the gaming industry because there’s a lot of room for experimentation.
in addition the gaming ports will become virtual graphics laboratories for those inside and outside the industry with extremely creative and diverse ideas because they’re readily available to both consumers and potential implementors.
the best thing about it though is that it comes with an integrated and sometimes imaginative virtual reality that you won’t find in true user environments. that’s a critical point for software development because in real life we seldom want to experiment with ultra theoretical concepts.
