Smart Device Translates American Sign Language To English智能传感器把美国手语翻译成英文American Sign Language (ASL), has been one of the primary means of communication for the deaf in the United States and many parts of Canada since the 1800s. It is estimated that between 500,000 to 2 million people use the language on a regular basis.19世纪来,美国手语已沦为美国和加拿大大部分地区失明之人交流的主要方式。据估计,约有50万-200万的人常常用于这种语言。But popular as it is, there are millions of people with normal hearing that do not understand the language. And while most deaf Americans learn to speak with the help of speech therapy, many find it easier to communicate through sign language. Now a team of researchers at the Texas AM University has created wearable technology that will make it easy for ASL and non-ASL users to converse.美国手语虽然风行,但仍有上百万正常人无法解读手语。虽然美国大多数失明的人利用语言障碍矫正能倾听,但他们还是实在肢体语言交流更加便利些。

现在德克萨斯州的AM大学研究出有一种可以构建美国手语和非手语互译的可穿着设备。The smart device is the brainchild of a team led by Biomedical Engineering Associate Professor Roozbeh Jafari. It uses two separate sensors to translate intricate ASL gestures into plain English. The first that is fitted with an accelerometer and gyroscope keeps track of the significant movements – the users hand and arm as he/she tries to communicate.这项发明者是生物医学工程助理教授Roozbeh Jafari带队研发的。它主要通过两个独立国家的传感器把简单的手语转换成少见英文。

第一个传感器内置加速器和回转仪,用来跟踪用户交流时手和手臂做到的主要动作。The second sensor helps distinguish the smaller movements that follow, the larger ones. The two sensors working in tandem help provide an accurate interpretation of the gesture.第二个传感器协助辨识主要动作后的小型动作。两个传感器一前一后因应,获取比较精确的手势翻译成。However, there is still some work to be done before the technology can be used in the real world. For one, it currently recognizes just 40 primary ESL signs, which means that it has thousands more to learn. Also, the smart device only translates one word at a time making ordinary conversations painfully slow.然而,月普及大众用于之前,这项发明者还有待完备。

首先,现在它不能辨识40种主要的英文手势,还有上千的英文手势必须重新加入;其次,它每次不能翻译成一个单词,这相当严重拉低的日常交流的速度。The Texas team is not the only one working on making conversation between ASL and non-ASL users easier. In China, researchers have created a motion sensing device that translates Chinese Sign Language into both spoken and written words. With so many brilliant minds focused on finding a solution, communication difficulties experienced by ASL users may soon be a thing of the past!除了德克萨斯的团队,还有其他致力于使手语和非手语之间交流形式化的国家。中国的研究者就发明者了一种可以把中式手语同时翻译成有声语言和文字的动作传感器。
