Joystick to Mouse
"Using existing technology is the fastest and most cost efficient way to create Assistive Technology. Whenever I can, I use this method for making new products. :-) "
Game pads/controllers and joysticks were never able to move your pointer, either on Mac, PC, or Chromebook :-( Hence my creation of Joystick to Mouse (JTM) back in the 90's! There are some freebies online but they are not supported by full-time people (like me!) and they are not as full featured (e.g. no ability to perform multiple click functions (double click, drag) by just a single click).
My Joystick to Mouse is the product you didn't think you need, but once you have it, something you won't want to live without.
