Sight is the most important sense of a human. For the most of the society, the perception performed by the sight organ is perceived as something very natural. Reflection on life without the sight is not common, which slows down the technological development aiming at reducing the social exclusion of persons with sight disabilities. The dynamical development of advanced technologies does not provide solutions for all the cases of illness. However, many tools exist which allow people with visual disabilities to interact with the outside world. In most cases these tools allow only for the exchange of very basic information. We present some problems associated with the visualization of images for the blind, with the attention concentrated upon business graphics. We also give some propositions to enhance the level of non-visual perception of images with the use of specialized tactile equipment.
