What's it like to wear Glass?

• Glass feels a lot like a pair of glasses, sans the lenses.

• The screen, just above the right eye, is surprisingly out-of-sight when you're not looking at it. (Fight the impulse to close your left eye.)

• The constant in-your-face information can feel overwhelming.

• Users control Glass with head movements, voice commands and taps on the mini-computer's touchpad.

• A faint beep alerts you when Glass detects something you may want to look at — a tweet, e-mail or text.

• Sound (such as phone calls) comes through "bone conduction" technology, not just speakers.

• A small button lets you snap photos or record video without using voice commands.

• Glass needs a Wi-Fi connection for most functions, except for photos and video. Images sync with the Glass owner's Google+ account.

• If you're looking at someone who is wearing Glass, you can tell the screen is on when the glass cube glows.

• Google says the battery lasts about a day, but we all know how that goes.
