Microsoft has developed a new smart phone app that identify eye signals and translates them into letters, allowing people with motor neurone disease (运动神经元症) to communicate with others from a phone.

The GazeSpeak app combines a smartphone’s camera with artificial intelligence to recognize eye movements immediately and change 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 are expensive, not strong under sunlight, and require frequent re-adjustment and material, relatively steady setups,” said Xiaoyi Zhang, a researcher at Microsoft who developed the technology.

“To ease off the disadvantages, we created GazeSpeak, an eye-gesture communication system that runs on a smartphone, and is designed to be low-cost, strong, 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 is equal 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 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. (265)
