Motor control disability users may have trouble using a standard mouse because it requires fine movements to click on screen controls such as buttons and sliders. So can visually impaired users.

These difficulties can come from vision and nerve-muscle disorders.

The University of Washington AIM Research Group has released, for free, two mouse cursor control systems for Windows that make locating the mouse on a target and interacting with it a lot easier for these folks.

The control systems can be used together. I’ll illustrate with the pictures from the research article itself as text explanation would be very long, and burdensome for the target audience.
