Paul Bardini shared on Thingiverse:
This device was created for a person with Guillian-Barre syndrome – causing nervous system inflammation and temporary paralysis. As they where being rehabilitated, this devices allow them to interact with a computer.
This joystick allow more finite movement of hand and fingers. The form is create to fit the alignment of a person laying in bed.
The large button on the back of the device allows the user to use the palm for the mouse click. Also the side button are facilitated by squeezing the device.
A new finger rest was designed to replace the existing joystick knob, allowing the two or three fingers to move the joystick. This minimises the fatigue with user.
Arduino micro controller and stock (very accessible) joystick parts and switches where used for other to replicate the device
Code is available on the Arduino website.
Every Thursday is #3dthursday here at Adafruit! The DIY 3D printing community has passion and dedication for making solid objects from digital models. Recently, we have noticed electronics projects integrated with 3D printed enclosures, brackets, and sculptures, so each Thursday we celebrate and highlight these bold pioneers!
Have you considered building a 3D project around an Arduino or other microcontroller? How about printing a bracket to mount your Raspberry Pi to the back of your HD monitor? And don’t forget the countless LED projects that are possible when you are modeling your projects in 3D!
