The Future Now: Sixth Sense Technology May Change How We Look at the World Forever: "The key here is that Sixth Sense recognizes the objects around you, displaying information automatically and letting you access it in any way you want, in the simplest way possible."
This is pretty cool but I want it to do one more thing. It should warn you and tell you what to do when an emergency occurs. I just read The Survivor's Club and there are a lot of people who die who won't have if they had just done something sensable like moving to the nearest exit. Oh, well I doubt they've thought of that since they haven't lived through anything traumatic yet.
