I am looking for something like this:
I would like to know if there is a program with an equivalent function to a reading guide on the computer, both for web browsing and reading natively on the screen. I know Windows has a Magnifier, but that's not really useful for a child with dyslexia.
For example, I need something that follows the mouse pointer and dims (changes foreground color/transparency etc. of) the screen everywhere else, apart from a "narrow" horizontal band centered at the pointer.
Free or paid, either would do. I just haven't been able to find anything with this functionality after looking for weeks.
