JSR Notes:

"Accessibility means access. It refers to the ability for everyone, regardless of disability or special needs, to access, use and benefit from everything within their environment. It is the “degree to which a product, device, service, or environment is available to as many people as possible.”  Wikipedia - Accessibility

Founded on the principles of Universal Design, the goal of accessibility is to create an inclusive society for people with physical, mobility, visual, auditory or cognitive disabilities. This means everyone has equal access to perceive, understand, engage, navigate and interact with all elements of the physical and digital world. "


 

Turn around the way of looking at this to be "Who are touch screens good for?"

...take a look...Click on the Apple in the upper left-hand corner, go to System Preferences, and then Accessibility.
