For over ten years human-computer interface, blind interaction and integration of visually impaired users with sighted users are the key issues of equal access to information and service. The vast research on alternative visualization, augmented communication, user-centered design and usability has been done, and much more projects and solutions are under development. However, several generations of graphical interfaces (Xerox, Apple, Microsoft) have brought less or no benefits for the blind users. Some elderly people still recall the times of DOS and command line, when both the system and application software levels were almost equally accessible. Nowadays, multi-processor operating systems are extremely complex and perform hundreds of routine tasks which are not necessary to be supervised or adapted for the user control at all.
