A Mobile Application for Interactive Sonification of Images for the Visually Impaired

The article presents a mobile application for interactive sonication of images, which is a tool supporting blind and partially sighted persons in interpretation of graphical content. The software can be used in blind education and in improving everyday life, work and entertainment. The article presents methods that facilitate interaction with the developed interactive sonification system and accelerate the teaching process, with a strong emphasis on customizing the user interface to the needs of people with visual impairments. A set of games that assist the user was created both to help with the familiarization with the available tools and to assess the progress made by the users. A test module consisting of a sequence of illustrations and prepared tasks was used to verify the effects of the exercises. The first positive results are reported of the empathic tests of the application in which normally sighted, but blindfolded volunteers have taken part.
