The software systems that millions of users use everyday around the world are mainly targeted at the main and the largest average group of people - people without disabilities. However, software systems are often inaccessible and unusable for another group of people - people with congenital or acquired disabilities. For a system to be accessible to people with special needs, it must be designed to take account of and be geared to their specific needs, opportunities for using the software systems and the hardware that provides them. This paper presents a model for creating a software system (for a physiological data analysis) that takes into account the needs of people with disabilities and in particular people with visual deficits. This model will ensure the assibilites of the software system and its easy use by both this target group and people without disabilities.
