Although Google Glass has, and is still getting a lot of negative attention for privacy concerns there are two OpenGlass projects that could deliver some amazing benefits. The video accompanying this article shows user trials of two different OpenGlass projects designed to inform users who can't see about what they are "looking" at. The first is "Question-Answer" which is pretty self explanatory. The user simply takes an image with glass and asks what it is. The question and image are sent to the cloud where the question is answered via services like Twitter of Amazon's Mechanical Turk. The second application "Memento" seems even more useful. The method behind it requires a sighted user to essentially teach glass about a scene. Then, when the visually impaired user walks into the same scene Memento will explain the scene to them.
This is the kind of stuff that science and technology truly changes the world with. Not the SlapChop...this. I was on the fence about whether or not Glass would end up being something useful or annoying and this easily tips the scale.
