A Scanning and reading software begins with using a scanner to scan paper documents into a computer. Optical character recognition (OCR) is the process of converting an image of text, such as a scanned paper document or electronic PDF file, into computer-editable text.


Screen Magnifiers

Screen magnification software is used by individuals with visual impairments to access information on a computers screen. The software enlarges any information on the screen including text, icons and graphics by pre-determined incremental factor.


Screen Readers and Talking Browsers

Screen readers are used to replace the visual display traditionally viewed on a monitor for those with visual disabilities. Hardware and software produce synthesized voice output for text displayed on the computer screen, as well as for keystrokes entered on the keyboard. Talking browsers use the same technology but the reading functions are limited to Internet use.
