The Accessible Equation Editor is a program that allows a user to create math expressions within a web page. The equation editor is used in a number of Pearson products, most visibly the TestNav assessment delivery system used for high-stakes testing.
The equation editor is accessible to users who are blind or visually impaired because it translates printed math notation into Nemeth braille, which can be displayed on a braille terminal, and it accepts Nemeth braille input, which it translates into printed math notation that it displays for a sighted user. A user who is blind can create math expressions that can be immediately read by a user who is sighted, and a sighted user can create math expressions that can be immediately read by a blind user.
