In the late 80’s I remember seeing many television concepts designed to engage the user. Remember Smell-O-Vision? Designers recognized interactivity was the future but they couldn’t foresee the advanced software and hardware solutions we have today. Check out MetaMirror, a concept software platform that enables you to access content relative to the show you’re watching. Almost everything today has secondary content and this is a much more elegant solution than sitting in front of a computer.
