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.

【新聞快訊】Google今天正式發(fā)布一個叫“Project Glass”的未來眼鏡概念設計。這款眼鏡將集智能手機、GPRS、相機于一身，在用戶眼前展現(xiàn)實時信息，只要眨眨眼就能拍照上傳、收發(fā)短信、查詢天氣路況等操作。

谷歌對外宣布產(chǎn)品開發(fā)計劃，旨在方便公司今后可以在公共場合中測試外型怪異的谷歌眼鏡。單從當前產(chǎn)品設計來看，谷歌眼鏡包括了一條可橫置于鼻梁上方的平行 框架、一個位于鏡框右側(cè)的寬條狀電腦，以及一個透明顯示屏。總體而言，該產(chǎn)品的外型絕對不會像我們通常理解的傳統(tǒng)眼鏡的設計。

眼鏡是基于Android操作系統(tǒng)運行的，看起來可以用語音操作、還可以視覺控制。在佩戴者視線上會有一個光標，向上看能與光標互動，查看天氣，發(fā)信息，做智能手機能做的事。除了智能手機功能，它還能與環(huán)境互動，擴充現(xiàn)實。 　　

根據(jù)視頻演示，Project Glass可提供天氣、交通路線等信息，用戶還可以用語言發(fā)信息、發(fā)出拍照指令等，它還能顯示附近的好友。舉個例子：如果看到地鐵停運，眼鏡會告訴用戶停 運的原因，提供替代路線；如果看到自己喜歡的書，可以查看書評和價格；如果在等朋友，眼鏡會顯示朋友的位置。
