from below, instead of sur veillance, which is to observe from above. Instead of this top-down surveillance society in which he thought that technology would enable early technology, he said "in the future, everyone will have tiny devices that will be capable of recording anything at any time." So during a protest or any civil rights violations, people will have power to look from below, instead of from above. His concept of wearable computing was very different from what I think people expect Google Glass to be. I think people expect Google Glass to be, "Well, I can take a lot of pictures all the time, which is really cool. But there's also gonna be a lot of ads, right?" And Steve Mann didn't like having other people's images on his reality. So he made a heads up display that allowed him to recognise rectangles that have advertisement in them, cancelled them out, and put text messages and other pieces of information, or research papers on them. So as he walked down the street, he would just see what he wanted to see. He was able to filter and put an ad-block on reality. He would walk into a supermarket and only see the products that he wanted to buy. I think that's a really important point where he was making his own and he calls it diminished reality. Augmented reality takes away from reality and includes your view. Diminished reality takes the reality that you don't like, edits it
