Ketchikan PL Tries MonoMouse

Back on July 18th, the Ketchikan Public Library announced it was doing a three month trial of the MonoMouse for visually impaired users. What's the MonoMouse? Let Rainbird Librarian explain:

The MonoMouse is an electronic magnifier that is light, quick to install, easy to use and very portable. Slightly larger than a standard computer mouse, you simply plug one end into an electrical outlet, the other into the VCR jack on your television, press the button and voila! It will magnify any print onto your TV screen; you simply slide the mouse across the page. You can use this to read books, magazines, newspapers - even your mail! Our device magnifies type 13x, so that it is larger than the standard Large Print format. It's designed to be ergonomic and lightweight, so even if you suffer from arthritis it will be easy to use. The instructions are even in a large print font!

If it works as advertised, it should be a boon to readers with vision difficulties. I know our library will be watching this experiment. How about yours? Are you using something similar already?
