Question

Microsoft has developed a new smartphone app that interprets eye signals and translates them into letters, allowing people with motor neurone disease to communicate with others from a phone.

The GazeSpeak app combines a smartphone’s camera with artificial intelligence to recognize eye movements in real time and convert them into letters, words and sentences. For people suffering from ALS（渐冻症）, also known as motor neurone disease, eye movement can be the only way they are able to communicate.

“Current eye-tracking input systems for people with ALS or other motor impairments are expensive, not robust under sunlight, and require frequent re-calibration and substantial, relatively immobile setups,” said Xiaoyi Zhang, a researcher at Microsoft who developed the technology.

“To mitigate the drawbacks…we created GazeSpeak, an eye-gesture communication system that runs on a smartphone, and is designed to be low-cost, robust, portable and easy to learn.”

The app is used by the listener by pointing their smartphone at the speaker. A chart that can be stuck to the back of the smartphone is then used by the speaker to determine which eye movements to make in order to communicate.

The sticker shows four grids of letters, which each correspond to a different eye movement. By looking up, down, left or right, the speaker selects which grids the letters they want belong to. The artificial intelligence algorithm is then able to predict the word or sentence they are trying to say.

Zhang’s research, Smartphone-Based Gaze Gesture Communication for People with Motor Disabilities, is set to be presented at the Conference on Human Factors in Computing Systems in May.

1.What should people with motor neurone disease do when they communicate with other people?

A. They need speak to the smartphone loudly.

B. They have to predict the sentence they are trying to say.

C. They need choose a grid on the back of the smartphone with eye movements.

D. They should work out the artificial intelligence algorithm in the smartphone.

【解析】

这是一篇说明文。文章介绍了一个新手机应用程序GazeSpeak app，可使ALS患者利用眼睛移动在手机上打字交流。

1.细节理解题。由第五段“A chart that can be stuck to the back of the smartphone is then used by the speaker to determine which eye movements to make in order to communicate.”和第六段“The sticker shows four grids of letters, which each correspond to a different eye movement.”可知，讲话者用一张贴在智能手机背面的图表，来判断为了交流，眼睛应该做出哪些动作。贴纸上有四个字母网格，每个字母代表不同的眼球运动。结合选项可知，C选项正确。故选C。

2.细节理解题。由第二段“The GazeSpeak app combines a smartphone’s camera with artificial intelligence to recognize eye movements in real time and convert them into letters, words and sentences.”可知，GazeSpeak将手机的摄像头与人工智能结合起来，可以实时识别眼球运动，并将其转换成字母、单词和句子。结合选项可知，D选项正确。故选D。

3.细节理解题。由第四段“To mitigate the drawbacks…we created GazeSpeak, an eye-gesture communication system that runs on a smartphone, and is designed to be low-cost, robust, portable and easy to learn.”可知，为了减轻这些缺点，我们开发了GazeSpeak，这是一款可以在智能手机上运行的眼神交流系统，设计成本低、功能强大、便于携带、易于学习。结合选项可知，B选项正确。故选B。
