By now, critics don't so much question the merits of Google Glass's features as they do how the wearable computer will change our perception and behaviors toward technology. Suddenly a strangely futuristic device is sitting on your face, and you're talking to it and snapping pictures just by winking. That'll creep anyone out—it brings up plenty of privacy concerns—and even Google executive chairman Eric Schmidt realizes this.

During a speech at Harvard University's Kennedy School of Government, Schmidt admitted that the experience can be weird, particularly voice recognition. But we might be able to chalk up his reactions toward Glass to how foreign the actual experience is—maybe one or two months from now it'll feel completely natural.

What's so strange about using Glass, I'd imagine, is the act of not actually physically doing anything with your hands, of swiping or typing, or holding a phone at all. You're no longer staring at a full HD screen that you can summon out of your pocket at any time; Glass is already there.

Voice recognition as a whole is a little strange, even if the technology has been available on mobile devices for the past few years. "People will have to develop new etiquette to deal with such products that can record surreptitiously and bring up information that only the wearer can see," Schmidt said. He also acknowledged that there are "obviously places where Google Glasses are inappropriate." Such as bathrooms.

It's still unclear how the greater public will react. Right now, only some developers and early backers have access to Glass, while a wider consumer release is still up to a year away. In the future, if you see someone waltzing down the street, mumbling commands to nobody in particular, they aren't crazy. They just have Glass.
