A scanner is a device that converts an image from a printed page to a computer file.The most important type of scanner in this context is the flatbed because with it you can scan pages from books at a high resolution to a computer file which can be edited. Scanned documents can be accessed by assistive technology devices such as speech synthesizers, text enlargers, or Braille embossers.
Screen reader software programs that work in conjunction with speech synthesizers provide verbalization of everything on the screen including control buttons, menus, text, and punctuation. They can provide access to print materials and manuals after they have been scanned into a computer and make a computer accessible to someone with limited or no vision.
