I remember seeing the movie Polyester back in the early 80s. It introduced smells via a scratch and sniff card. There were numbers on the card and when a number was shown on the screen you would scratch the corresponding number on the card and get a smell. It worked but I thought it was a novelty and did not really add anything to the movie experience.
