Joystick for people without fine pincer movement

thingiverse

This object is designed to primarily help those who do not have great movement with their forefingers and thumbs, forming the famous forceps and use a motorized chair . This was inspired from my own needs when I got a motorized chair, last year. The motorized chair that I use came only with a joystick model in pyramidal (conventional) shape . However, for my needs, this format is not very functional , since my forceps movements are limited , difficulting to control the chair. So, I developed a joystick model where I hold it with my whole hand to have a better control (speed and direction)which makes its easier to use. The model was designed in Solid Works and the measures initially refer to the size of my hand.
