Approaches to the visual information substitution for people with visual impairments are considered. The choice of converting visual information into tactile is substantiated. The structure of the tactile to visual substitution device, which transmits to the user information about surface unevenness, is proposed. The general principle for transforming information about presence and appearance of the obstacles has been developed. The basic parameters of the display (the device for transforming visual information into tactile sense) are determined, a method for encoding information about the surface in front of user changes and the set of basic templates are developed. Demonstrated the possibility of using the developed approach for other needs by the example of transmission of textual information using Braille.
