Information and Technological Service for the Accompaniment of the Educational Process of People with Visual Impairments

The authors propose innovative approaches to the improvement of information technologies, methods and tools, which implement the formation of electronic library funds with specialized information products, integrating various types of information to provide information needs of people with disabilities. It is offered the new approaches to the formation of information resources and electronic libraries for this category of people promoting the processes of inclusive education. The processes of content preparation for providing convenient information and technological interaction of the blind with the information resources are analyzed, as well as the choice of the DAISY format (Digital Accessible Information System) for the creation of information products (audio books) with the use of flexible navigation mechanisms is substantiated. Moreover, it is proposed the classification of documents, which allows you to choose the levels of their structuring for effective transformation into DAISY format. The developed technology by authors is introduced and allows you to convert mathematical formulas of different complexity into a form that can be pronounced effectively by a synthesizer of the Ukrainian language. The developed software and algorithmic means of sounding mathematical formulas in Ukrainian have given an opportunity to dub the Ukrainian technical texts with the help of a language synthesizer, fill DAISY books with technical content and convert the mathematical formulas into a text description. To convert the mathematical formulas presented in various versions of the MathML (presentation and semantic) records into an Ukrainian text, a special system of rules has been developed, which consists of rules for writing mathematical symbols, operators, general and specified expressions.
