(2019·杭州模拟)Microsoft has developed a new smartphone app that interprets eye signals and translates them into letters, allowing people with ALS (渐冻症) 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, also known as motor neurone (神经元) 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 disabilities are expensive, not constant under sunlight, and require frequent readjustment and considerable, relatively fixed systems，” said Xiaoyi Zhang, a researcher at Microsoft who developed the technology.
“To reduce the drawbacks ... we created GazeSpeak, an eye－gesture communication system running on a smartphone, and is designed to be low－cost, constant, portable and easy to learn.”
The app is used by the listener by pointing their smartphone at the speaker. A chart stuck to the back of the smartphone is then used by the speaker to determine which eye movements to make for communication.
The label shows four grids (方格) of letters, which each correspond to a different eye movement. By looking up, down, left or right, the speaker selects which grids they want the letters belong to. The artificial intelligence algorithm (计算程序) 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.
