If you venture into a coffee shop in the coming months and see someone with a pair of futuristic glasses that look like a prop from “Star Trek,” don’t worry. It’s probably just a Google employee testing the company’s new augmented-reality glasses。

　　On Wednesday, Google gave people a clearer picture of its secret initiative called Project Glass. The glasses are the company’s first venture into wearable computing.The glasses are not yet for sale. Google will, however, be testing them in public。

　　In a post shared on Google Plus, employees in the company laboratory known as Google X, including Babak Parviz, Steve Lee and Sebastian Thrun, asked people for input about the prototype of Project Glass. Mr. Lee, a Google product manager and originally worked on Google mapping software Latitude, mobile maps and indoor maps, is responsible for the software component and the location-based aspects of the glasses。

　　“We’re sharing this information now because we want to start a conversation and learn from your valuable input,” the three employees wrote. “Please follow along as we share some of our ideas and stories. We’d love to hear yours, too. What would you like to see from Project Glass?”

　　The prototype version Google showed off on Wednesday looked like a very polished and well-designed pair of wrap-around glasses with a clear display that sits above the eye. The glasses can stream information to the lenses and allow the wearer to send and receive messages through voice commands. There is also a built-in camera to record video and take pictures。

　　A video released by Google on Wednesday, which can be seen below, showed potential uses for Project Glass. A man wanders around the streets of New York City, communicating with friends, seeing maps and information, and snapping pictures. It concludes with him video-chatting with a girlfriend as the sun sets over the city. All of this is seen through the augmented-reality glasses。

　　Early reports of the glasses said prototypes could look like a pair of Oakley Thumps — which are clunky and obtrusive sunglasses — but the version Google unveiled Wednesday looks more graceful. There are reportedly dozens of other shapes and variations of the glasses in the works, some of which can sit over a person’s normal eyeglasses。

　　One person who had used the glasses said: “They let technology get out of your way. If I want to take a picture I don’t have to reach into my pocket and take out my phone; I just press a button at the top of the glasses and that’s it。”

　　Project Glass is one of many projects currently being built inside the Google X offices, a secretive laboratory near Google’s main Mountain View, Calif., campus where engineers and scientists are also working on robots and space elevators。

　　Google今天正式发布一个叫“Project Glass”的未来眼镜概念设计。这款眼镜将集智能手机、GPRS、相机于一身，在用户眼前展现实时信息，只要眨眨眼就能拍照上传、收发短信、查询天气路况等操作。

　　谷歌对外宣布产品开发计划，旨在方便公司今后可以在公共场合中测试外型怪异的谷歌眼镜。单从当前产品设计来看，谷歌眼镜包括了一条可横置于鼻梁上方的平行 框架、一个位于镜框右侧的宽条状电脑，以及一个透明显示屏。总体而言，该产品的外型绝对不会像我们通常理解的传统眼镜的设计。

　　眼镜是基于Android操作系统运行的，看起来可以用语音操作、还可以视觉控制。在佩戴者视线上会有一个光标，向上看能与光标互动，查看天气，发信息，做智能手机能做的事。除了智能手机功能，它还能与环境互动，扩充现实。

　　根据视频演示，Project Glass可提供天气、交通路线等信息，用户还可以用语言发信息、发出拍照指令等，它还能显示附近的好友。举个例子：如果看到地铁停运，眼镜会告诉用户停 运的原因，提供替代路线；如果看到自己喜欢的书，可以查看书评和价格；如果在等朋友，眼镜会显示朋友的位置。
