Microsoft Unveils Wearable Device to Help with Parkinson's Symptoms
From: R&D Magazine - 05/12/2017

Microsoft unveiled a prototype smartwatch, dubbed Emma, which uses vibrations
to help individuals with Parkinson's disease control hand tremors.

Parkinson's causes the brain to releases extra signals to muscles, creating
an internal feedback loop that causes muscles to perform many movements at
once, resulting in tremors. The Emma device is built with small coin cell
motors that vibrate to distract the user's brain from trying to create these
tremors.

The idea is to have the device calm muscles movements and make it easier to
perform simple tasks, according to Microsoft.
