This is a free Windows utility that makes mouse clicking easier. It displays a large, round pointer; when the user clicks any button, the area under the pointer is magnified. The user then moves the standard mouse pointer to make their selection. Pointing Magnifier is designed to help people with dexterity disabilities, but might also be useful as a “spot” magnifier for people with low vision. I tried it out and it is pretty cool.
