NEW YORK >> If you think texting and walking is dangerous, just wait until everyone’s 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 or even buy a few things online as you walk around.

These glasses can do everything you now need a smartphone or tablet computer to accomplish.

Mind you, the technology doesn’t actually exist. Google offered a glimpse of "Project Glass" in a video and blog post this week as a way to start a discussion and solicit ideas.

The glasses hint at endless possibilities. But the project also opens up a minefield of challenges around public safety, privacy, practicality, even fashion sensibility.
