Ugh, I don't want to wear glasses that are constantly feeding my information.
Oh yes...iWould.
Imagine walking through a mall, and an arrow in your HUD directs you to the item you're after... Gesture or Touch to purchase. Look at a sku to get more information, etc.
Compass/GPS in a HUD while out and about.
Speech to and from text for messaging, twitter, etc.
Blink/Gesture to convert to sunglasses, or autodetect for preference for shading.
Or, a security team in an airport. Suspicious person tagged via facial recognition by one agent, now glows when looked at by any other agent. And arrow with directions to potential problem areas in huge airports. Facial movement detection software lets the agent know if someone is possibly lying while talking to them.
Walk through a car lot, instant CarFax after you look at a VIN.
Opaque the glasses and read while listening to music....Oh wait! Drivers on cell phones are bad enough!
