A friend showed me this on the bbc news web page:
Students at the Imperial College London and Royal College of Art have developed a vibrating pen that hopes to help patients with Parkinson's disease.
The team of engineers and designers created the pen to try to combat a condition known as micrographia which causes people to write in small or cramped handwriting.
The pen is still in the testing phase. BBC Click's spoke to Lucy Jung, one of the students behind the device.
More at BBC.com/Click and @BBCClick.
there is a short clip showing the pen and how it works.
take a look it's great news for all of us with this problem.
