With the word "Emma," most people think about Emma Watson, Hermione's actor in the movie "Harry Potter," but today I'm going to introduce another Emma. She is Emma Lawton, a 33-year-old with Parkinson's disease. The prominent symptom of this degenerative nervous system disorder in her body is tremor, a fatal blow to a graphic designer. According to foreign media, "Parkinson's Life" website reported that recently, a smart watch developed by Microsoft saved her work and life. The wearable device that prevents hand shaking allowed her to regain the ability to draw and write. Emma's story first appeared on the BBC Channel 2 documentary about some of the country's top engineers and designers to create a lifestyle-changing program for people with chronic diseases. In the film, Emma tells how everything is affected by Parkinson's disease. She said, "I always tend to avoid sketching and writing, because it is futile at all, and even trying to draw a straight line is not smooth, signing my name is something that has made her unbelievable." Zhang Haiyan, director of innovation at Microsoft Research, is determined to develop a device for Emma to help her control the pen in her hand. Zhang Haiyan in the past have done in the biomedical data mining, created the relevant applications, just to help research and development. In order to create a damping device to help return to normal life Emma, ​​Zhang Haiyan used vibrating tableware invented by her gyroscope principle. Wearable vibrations counteract the uncontrolled tremor in Emma's hand and allow her to control the pen more accurately. Emma said "it makes me very excited, I feel the future can finally be controlled, returned to their own hands," and even let her forget her smart watch and shake things. It is reported that about 70% of Parkinson's patients, are often spent in tremor, hand trembling is one of the group's most common symptoms. Microsoft and its researchers say they hope the newly developed technology will bring convenience to more people in the future.
