Origin and Purpose

Every summer, Envision hosts camp to help teens acclimate to accessible technology. In 2013, it was suggested that camp transition from a commercial screen reader to NVDA, an open source screen reader. The most significant missing feature which was necessary for the camp was a built-in magnifier.

To rectify this, Envision contracted with Green Light Go to help provide an integration addon for NVDA, which would couple the open source software with the built-in Windows 7 magnifier.
