Abstract

To investigate appropriate representation of numerical data to blind people, a user experiment was conducted. Its results have shown that embossed graphs give quicker and correct access to the data than braille and electronic tables. Based on this observation, we started developing software for creation of embossed graphs which can be operated by blind people. Up until now line graphs can be created with this software.
