Pbs Kids Design Squad: Supporting Steady Hands

Have you heard of a disease called Parkinson's? When people have this disease they often show signs or symptoms, like shaking uncontrollably. This shaking can make doing simple things harder. Emma Lawton is a person with Parkinson's, and she loves to draw. Ever since she got sick, she hasn't been able to draw or write very well, because her hands shake too much. An inventor named Haiyan Zhang wanted to help Emma, so she designed an amazing device! This wearable prototype looks like a watch, and it's very simple for Emma to use. It helps her in a really cool way: it sends electric signals that distract Emma's brain so she doesn't shake!
