The Yahoo! Accessibility Lab has created a tool for people with Hemianopia. Find out how it works.  Hemianopia, also known as hemianopsia, is a neurological condition that affects vision. It’s commonly associated with strokes and brain injuries.

 

The Hemianopia plugin works quite simply. After installing, the plugin will draw a line on the page, upon which the user can click to change the color or disable it. They can also click and drag the bar to the best location for the site.
