Basically, instead of spending $6K on a portable brailler, the iPad converts into one. The article states that the "virtual keyboard provides a custom fit for your phalanges no matter how big or small they may be". The app "populates the keys underneath the fingers" wherever they are placed. This is huge for blind folks as the most difficult aspect of the iPad is knowing where "buttons" are on the touch screen. They are working out some technical and legal details before it is made available...more on this to come! Thanks for sharing Josh!
