The development of user-oriented technologies is related not only to compliance with standards, rules and good practices for their usability but also to their accessibility. For people with special needs, assistive technologies have been developed to ensure the use of modern information and communication technologies. The choice of a particular tool depends mostly on the user's operating system. The aim of this research paper is to study the current state of the accessibility software tools designed for an operating system Linux and especially used by visually impaired people. The specific context of the considering of the study’s objective is the possibility of using such technologies by Bulgarian users. The applied approach of the research is content analysis of scientific publications, official documentation of Linux accessibility tools, and legal provisions and classifiers of international organizations. The results of the study are useful to other researchers who work in the area of accessibility of software technologies, including software companies that develop solutions for visually impaired people. For the purpose of the article several tests are performed with the studied tools, on the basis of which the conclusions of the study are made. On the base of the comparative study of assistive software tools the main conclusion of the paper is made: Bulgarian visually impaired users are limited to work with Linux operating system because of the lack of the Bulgarian language support.
