Microsoft Inventor Creates Device to Ease Tremors of Her Friend with Parkinson’s

Microsoft Inventor Creates Device to Ease Tremors of Her Friend with Parkinson’s

Parkinson’s disease causes tremors — in some cases severe enough that patients can’t write or eat properly.

Microsoft’s Emma Watch can alleviate the hand tremors that many patients experience.

Haiyan Zhang, a Microsoft innovation director, invented the Emma Watch after meeting Emma Lawton, a graphic designer who was 29 when she was diagnosed with Parkinson’s.

The two met in London. As they got to know each another, Zhang noticed that Emma’s constant tremors made her graphic design work difficult. At times she couldn’t even write her name.

Zhang started developing prototypes of a device that could help ease tremors, giving Emma and other Parkinson’s patients their dexterity back.

Zhang is committed to helping others through innovation. She considers herself part of the Maker movement, a subculture that merges the ingenuity of do-it-yourself efforts with the engineering achievements of modern technology. In fact, Zhang’s mission at Microsoft is very much related to her involvement in the Maker movement.

After experimenting with prototypes, Zhang created the Emma Watch. Its tiny motors counters tremors by generating an equal amount of force against them, keeping movement steady.

When Lawton tried the watch for the first time, she and Zhang were astonished at how much it helped alleviate the tremors. Lawton could write her name, draw straight lines, rectangles — basically, whatever she wanted. Check out the short video below to see her and Zhang’s reaction to the watch.

“As someone who works in technology and thinks about new kinds of things, I don’t really see the impact of that on people’s lives or on an individual,” Zhang said in a Microsoft Central news story written by Jason Ward. “For me, it was so powerful to see her life made better.”

“To be able to write your name is a basic human right,” Lawton said. “To be able to do it and do it neatly is really special to me now. It’s empowering. It made me feel that I could do anything.”

For now, the Emma Watch is the only device of its kind. But Zhang and her Microsoft team want to harness artificial intelligence to develop a device that detects and counteracts other Parkinson’s symptoms, such as body rigidity, slow walking, and falling.

    I read about the Emma watch and wanderd wether I could buy one. I am sixtytwo and was diagnozed with Parkinson fout years ago and suffer drom severe righthand tremor. I would-be appreciatie it of you could het in touch with me 0031652384740.
    Kind regards, Prof. Dr. René J. Tissen

  2. Anne Clarke says:

    Is this device available for other PD sufferers or is there literally only one device in the world? If it’s not available, are there any plans to make it available ? I have PD and I am anti-drug so this very exciting to me. Thank you for all that you are doing!

  3. Susan Christie says:

    Id give my left arm if you could make my right arm work like that in the video, without tremour. Will it be affordable in the uk. Please?

  4. Patty says:

    I have a constant tremor in my left leg that I think could be helped with a device like this wrist band. Who can I contact about getting one?

  5. Trevor Philpott says:

    Does anyone know about NADH as a miracle cure for PD, please? It is a supplement, not a drug and apparently can have a very positive impact in a short period of time.

  6. Cheri Wasco says:

    My father is demoralized by his inability to write now. Along with all of the PD symptoms, this would be amazing for him. Can it be purchased? Cheri

    *** S.O.S. *** …
    Does “anyone” out there have any “updated” information on the “Emma Watch”… for Tremors ???
    – Where is it in the development process ???
    – When will it be released for general use for people with Parkinson ALS, Essential Tremors ???
    _ Projected cost of the watch ???
    Thank you very much !!!
