“Project Glass,” an early prototype of Google's futuristic Internet-connected glasses, are creating a stir around the world. The specs are said to give you directions, let you video chat, shop and do everything else you now need a hand-held gadget to accomplish. Google gave a glimpse of “Project Glass” in a video and blog post. The glasses are still in the early stages of development.

NEW YORK — If you think texting while walking is dangerous, just wait until everyone starts wearing Google’s futuristic, Internet-connected glasses.

While wearing a pair, you can see directions to your destination appear literally before your eyes. You can talk to friends over video chat, take a photo or even buy a few things online as you walk around.

These glasses can do anything you now need a smartphone or tablet computer to do — and then some.

Google gave a glimpse of “Project Glass” in a video and blog post this week. Still in an early prototype stage, the glasses open up endless possibilities — as well as challenges to safety, privacy and fashion sensibility.

The prototypes Google displayed have a sleek wrap-around look and appear nothing like clunky 3-D glasses. But if Google isn’t careful, they could be dismissed as a kind of Bluetooth earpiece of the future, a fashion faux-pas where bulky looks outweigh marginal utility.

In development for a couple of years, the project is the brainchild of Google X, the online search-leader’s secret facility that spawned the self-driving car and could one day send elevators into space.

If it takes off, it could bring reality another step closer to science fiction, where the line between human and machine blurs.

“My son is 4 years old and this is going to be his generation’s reality,” said Guy Bailey, who works as a social media supervisor for a university outside Atlanta. He expects it might even be followed by body implants, so that in 10 years or so you’ll be able to get such a “heads-up display” inside your head.

But is that what people want?

“There is a lot of data about the world that would be great if more people had access to as they are walking down the street,” said Jason Tester, research director at the nonprofit Institute For the Future in Palo Alto, Calif.

That said, “once that information is not only at our fingertips but literally in our field of view, it may become too much.”

Always-on smartphones with their constant Twitter feeds, real-time weather updates and “Angry Birds” games are already leaving people with a sense of information overload. But at least you can put your smartphone away. Having all that in front of your eyes could become too much.

“Sometimes you want to stop and smell the roses,” said Scott Steinberg, CEO of technology consulting company TechSavvy Global. “It doesn’t mean you want to call up every single fact about them on the Internet.”

Still, it doesn’t take much to imagine the possibilities. What if you could instantly see the Facebook profile of the person sitting next to you on the bus? Look through your wall to find out where electrical leads are, so you know where to drill?

“Not paint your house, because the people who looked at your house could see whatever color they wanted it in?” pondered veteran technology analyst Rob Enderle.

Wearing the glasses could turn the Internet into a tool in the same way that our memory is a tool now, mused science fiction writer and computer scientist Vernor Vinge. His 2007 book, “Rainbow’s End,” set in the not-so-distant future, has people interacting with the world through their contact lenses, as if they had a smartphone embedded in their eyes.

Unlike Google’s glasses, at least in their current state, Vinge’s lenses know what you are looking at and can augment your reality based on that. That could come next, though.

“Things we used to think were magic, we now take for granted: the ability to get a map instantly, to find information quickly and easily, to choose any video from millions on YouTube rather than just a few TV channels,” wrote Google CEO Larry Page in a letter posted on the company’s website Thursday.
