Wearable device helps steady hand of designer who has Parkinson’s disease

Graphic designer Emma Lawton was diagnosed with Parkinson’s disease three years ago at the age of 29. Now, with the help of a BBC project and Haiyan Zhang, Microsoft Research Cambridge’s innovation director, she’s been able to use a wearable device to reclaim her lifelong passion for drawing and sketching.

The Big Life Fix is a BBC series that got underway Wednesday. Lawton was featured in the first episode of the series, which focuses on people in need who turn to some of the United Kingdom’s top inventors for solutions to problems that affect their day-to-day life.

Other projects being tackled by the show include a solution for a terminally ill photographer who can no longer operate a camera, and the construction of a specialized BMX bike for a child born with no hands or feet.

Parkinson’s disease can cause sufferer’s hands to shake uncontrollably, making even simple actions almost impossible to carry out. Lawton’s tremor was becoming so severe that her career as a graphic designer was in serious jeopardy, according to a report from MS Power User.

Zhang previously created cutlery for disabled people that reacts to their movements to avoid spilling food. Building upon that foundation, she was able to create a wrist-worn device — dubbed the Emma — that helps facilitate drawing and sketching by counteracting the impulses being sent to the wearer’s arm.

The Emma intentionally shakes the user’s arm, interrupting the feedback loop that impedes normal movement. While wearing the device, Lawton was able to draw straight lines, and even write legibly. Since the BBC program was filmed, she’s apparently been wearing the Emma on a daily basis.

Zhang currently has no plans to develop the Emma into a commercial release, having designed the device to fit Lawton’s particular needs. However, she hopes that others will take the basis of the technology and continue to develop it further.
