Imagine a Braille[盲文] of the physical world. A team of final-year engineering students from Cambridge University have developed a business plan for Vision Mitt, a glove-based mobility[移动] aid for blind and visually impaired[受损] people.
　　Their Vision Mitt combines existing technology and new software to enable the user to 襰ense?their surroundings using ultrasonic[超声波] sensors[传感器] and vibration[振动] feedback actuators[发动器], to supplement[补充] existing mobility aids like guide dogs or sticks.
　　The team wanted to produce something of social benefit, and drew inspiration[灵感] from the sonar[声纳] techniques used by bats to navigate without sight. Team member Samaan Rahman describes the concept as “a glove which houses ultrasonic sensors mounted on[将某物置于] the back, similar to parking sensors, where the closer you get to an object the quicker and louder the series of beeps[哔哔声]. Instead of beeps, we use vibrating motors[发动器] similar to those on a mobile phone. The closer your hand is to the object, the higher the frequency[频率] of vibrations.”
　　Incorporating[结合] the technology into a glove has proven popular with their users. They like the fact that it frees your hands for other tasks, appears inconspicuous[不显眼的], and is cheaper than other electronic navigation products.
　　For now, the students are concentrating on finishing their degrees, but investors are lining up to help put the Vision Mitt on the right hands.
　　
　　想象一下，有一套盲文可以描绘这个物质世界。一队来自英国剑桥大学的大四工科学生开发了一个“视觉手套”的商业计划，也就是一款辅助失明和视障人士行动的手套。
　　他们的视觉手套结合了现有技术和新软件，佩戴者可以通过超声波传感器和振动接收器“感知”周围的环境，可以作为使用者现有的行动协助工具（如导盲犬或手杖等）的有力补充。
　　这支团队希望发明一些有社会价值的产品，他们的灵感来源于蝙蝠可以在无需视力的情况下通过声纳进行导航的原理。队员萨马恩•拉曼对该产品的设计理念描述道：“手套背面装有超声波传感器，类似于停车感应器，你越靠近物体，响声就会越急越大。不过我们使用了类似于手机振动的仪器来代替这哔哔声。你的手越靠近物体，手套振动的频率就越高。”
　　这种将导航技术和手套结合在一起的办法受到用户的青睐，因为这能让他们腾出手来做其它事情，又不太显眼，而且比其它的电子导航产品更便宜。
　　现在，这帮学生忙于完成学业，但投资者们已紧锣密鼓地行动，让视觉手套能尽早到需要的人的手里。
