A lot more people are about to get a chance to buy Google Glass. It’s the Internet-connected eyewear that has become the hottest sale.

Google will sell the “Explorer” version(版本) of Glass to any U.S. person who places an online order for the device beginning at 9am. PDT April 15. The product will cost $1,500. Google is saying how many sets of Glass will be available during the limited-time offer.

This version of Glass, though, still isn’t the perfect product that Google hopes to sell in stores later this year.

For now, Google is still trying to recruit(招聘) more people willing to serve as volunteers for its attempt to build a wearable device that features some of the same feature as a smart phone. “ Our Explorers are moms, bakers, surgeons, rockers, and each new Explorer has brought a new view that is making Glass better,” Google said.

The device has a small screen attached above the right eye. A user can check e-mails, see Twitter post or get directions without having to use a phone. It can also take hands-free photos and video through voice-activated(声控的) commands. The ability to record images so easily has raised safely concerns about drivers wearing Glass. The lawmakers have to draw up new rules forbidding use of the device in moving vehicles.

Google regards Glass as a breakthrough(突破). It will make it easier for people to surf the Internet while on the go. They also hope that the device could help police officers, firefighters, doctors and reporters do their jobs better.
