Google Glass- Is this safe technology

Google Glass is a headset that you wear like a pair of eyeglasses.The headset has a small prism-like screen tucked into the upper corner of the frame that keeps you constantly plugged in to your e-mail, calls and other notifications so you don't have to miss a beat.

The idea behind Glass is that bringing the technology closer will actually make it easier to disengage from it. Rather than having your head bent over a screen in your hand, you can look up. And rather than flicking through a list of notifications or e-mails to see if you missed anything important, you can make that decision immediately and get on with your day.

Not that you can abandon your phone altogether. Glass is designed to provide a second screen for your device, so you need to hook it up to your phone to get the notifications and other information.
The idea is to have that little notification bar from your phone in a place where you don't have to strain to see it, so you can actually look where you're going while you're out and about and stay plugged in to your inbox.

There are different ways to operate Glass. The device has a touchpad on the side the part that goes over your ear that you can tap or swipe for navigation. You can use voice commands for Glass by adding the phrase "Okay, Glass" to the start of whatever you tell it to do launch an app, take a picture, start a call, etc. Users can also wake up Glass by looking up.
