What fields do you think technologies like Glass, combined with computer vision and machine learning, could disrupt?

Some random ones of mine include: - Analysis of plants (for gardeners): tell which ones are healthy or not - Mineral mining: see which rocks might contain precious minerals, rather than guess-and-check - For sports players: project where players/balls are going to be in the near future, draw it (overlay) on your vision - Learning of any visually-oriented task (like what though?)

What ideas do you see being useful?
