元器件交易网讯 5月16日消息，据外媒报道，美空军正在评估谷歌眼镜的作战能力，并开发出软件模型——佩戴谷歌眼镜的地面人员可侦查狙击手、救治伤员。

　　研究人员表示，“我们正在通过直观方式提高作战人员的效率”，谷歌眼镜佩戴者可用触摸板、头部动作和语音控制屏幕。研究人员开发的应用还包括威胁侦测系统，狙击手的距离和方位数据会直接传输到谷歌眼镜的屏幕上。另一个应用可以发送短信，在需要隐蔽无法语言交流的情景下使用。

　　空军研究人员还开发了一款用于安卓智能机的医疗应用，可通过士兵佩戴在胸前的无线模块接受心率、呼吸和血氧情况。这些数据将汇总到军医佩戴的谷歌眼镜屏幕上，查看受伤者的生命体征同时处理伤员。（元器件交易网毛毛  摘译）

　　The Air Force is evaluating the combateffectiveness of Google Glass, the wearable computer that Google Inc. put onsale to the general public Tuesday. A research group at Ohio’s Wright-PattersonAir Force Base says it has created software prototypes that could helpGlass-wearing ground personnel detect snipers or treat the wounded.

　　The Air Force has already been using headmounted displays for certain functions, most notably with its pilots and forits pararsecue jumpers, who are tasked with recovery and medical treatment. Butmembers of Air Force’s Battlefield Air Targeting, Man-Aided Knowledge programsay Google Glass’s design makes it more battlefield-friendly for groundpersonnel than clunkier, more expensive head-mounted models offered by defensecontractors.

　　“We’re trying to improve the war fighter’s mission efficiency as wellas effectiveness through intuitive displays,” said Gregory Burnett, the chiefengineer of the group, also known as the BATMA(N) program. Glass featuresdata-displaying screen users control via a touchpad, head gestures and voice.

　　The applications Air Force researchers aredeveloping includes one that connects to a threat detection software systemwhich feeds data on the range and bearing of snipers directly to a Glassscreen. Another use case is a text messaging tool that allows soldiers tocommunicate without speaking, which he said is useful for in situations thatrequire stealth. A navigation app helps guide Glass wearers across unfamiliarterrain.

　　Air Force researchers have also built anAndroid smartphone medical application that receives heart rhythm, respirationand blood oxygen level information from wireless vital monitors war fighterswear on their chests. That data is then fed to a Glass-wearing medic who canreview a wounded individual’s vital signs while keeping hands free to attend tothe wounded. “We distill the data [on the smartphone] and push that out toGlass, which is connected to the mobile device,” said Mr. Burnett.

　　Researchers at BATMA(N) sees Glass as morefunctional, efficient and cheaper option to the than most head-mounted displaysbuilt by defense contractors. Most displays directly cover the eye. Glass sitsjust above the eye to display “contextual awareness information in the battlespace” without obstructing war fighter’s views, said Mr. Burnett. Head-mounteddisplays are also heavier and clunkier because they are ruggedized to handlerough battlefield environments. Defense-grade displays draw their processingpower from a separate computer, such as a mobile computer wired to the helmet,or a small laptop soldiers wear on their chest, said Mr. Burnett. They alsotypically require the wearer to use a mouse to control the device, which ishardly optimal in combat situations. In contrast, Glass’ computing power isintegrated within the frame.

　　Traditional head-mounted displays are alsomore expensive. Glass’ $1,500 price tag is more economical than defenseindustry displays that can cost anywhere from $5,000 to $10,000 or more.Although Mr. Burnett said performance was the prevailing factor of using Glass,he acknowledged the Air Force doesn’t want to “disregard all of thecapabilities and cost-savings we may leverage from the commercial sector.”

　　One liability Glass has on the battlefieldis that it could break on forceful impacts. Mr. Burnett said that a Glasswearer’s performance was greatly enhanced by the device’s form factor, he’dsuggest that the commercial markets develop a more durable solution, “whetherthat be Google or some other company.”

　　JP Gownder, a Forrester Research Inc.FORR-2.05% analyst who tracks wearable computing, says Glass affords the militarysome hands-free capabilities for information access, just as it has in healthcare, manufacturing and legal industries. But he said it may not be able toprovide the same situational awareness of emerging wearable computers thatfeature augmented reality, which can superimpose information about terrain,machines or objects in the field over what one sees in front of one’s face. “Ithink there will be limits on what it can do,” said Mr. Gownder.
