This Web page uses a weighted font called OpenDyslexic.
Dyslexia is a condition suffered by many people. Those who have dyslexia have trouble reading, in part because their minds flip the letters over. Research has shown that one factor which causes the flip is the style of text. Research has also shown that some of the effects can be minimized when the text is visually weighted, making the letters appear "heavier" at the bottom. Dyslexic readers can use the weighted letters to help them keep themselves from flipping.
The OpenDyslexic font is the creation of Abelardo Gonzales. The font has been released using a Creative Commons Attribution 3.0 license.
The beauty of that license is that it allows very broad ability to use the font as long as you give Mr. Gonzales the credit for creating the font. It is also appropriate to link to the OpenDyslexic Web site.
Combining this font with Open Educational Resources (OER) might help many students to minimize their reading difficulties. If educators who are using and creating OER materials also provide a version printed with OpenDyslexic, they'll potentially better engage the dyslexic students in their classes. That's a real plus.
