A lot of people are saying that using this device would require speaking all kinds of private things out loud in public, but people would likely alter their behavior and use of the device in public. The nature of the questions they ask would be different, they would self-censor. In private they'd use it differently. People don't watch porn on their phone in the subway (mostly) and they wouldn't state their credit card info out loud using this on a subway either. If you have to say "take a photo" then the people around you know you are taking a photo. If it can record video it should beep occasionally or something. I still don't have a complete idea of how the UI works though, can the projector project onto a wall instead of your hand? Can you listen to replies via wireless earbuds? Would like to see something more in depth about how to use it and what can be accomplished with it.
