A-level Product design

Hi guys!

I'm Ed. I currently study product design in 6th form. My current project is to design and make a product that helps people with Parkinson's disease specially targeting their tremors. 

As Nelle Harper said "Don’t judge a man until you have walked a mile in his shoes". I don't want to start assuming the types of problems you might have because i have never experienced Parkinson's disease myself.

Please could you tell me how the tremors affect you with your daily activities(eating,drink,dressing,etc)? So i can have a general knowledge about what i should design.

Thank you in advance

Edwin Cheng
