Video display hooks needed for off–screen model.

November 30, 2011

As many of you may or may not know, there is a freeware open-source screen reader for blind and visually impaired people written in Python called NVDA (Nonvisual Desktop Access.) The software runs on Windows2000, xp (all versions) and vista. The project is coming along quickly however we need video display hooks to create an off-screen model so that NVDA can give more information to the blind computer user, and also implement such things as mouse simulation. Video display hooks will also allow us to support even more applications and enhance the support of the current applications even more-so. These video display hooks for the offscreen model need to be written in Python if possible. To download NVDA, go to

We as developers and testers haven’t been able to figure out how to implement video display hooks so NVDA can utilise an off-screen model so far. Any help would be greatly appreciated. You may contact me about this project at Josh Kennedy msn messenger contact: Josh Kennedy skype contact: jkenn337

Again any assistance with this project would be greatly apreciated. Video display hooks will greatly increase the abilities of the NVDA screen-reader. Note, this position is not restricted to blind programmers if you have sight and can help please contact me. There is also an email list for NVDA at .
