Some software applications have retained their historical links to the days when graphs and tables were rendered in well controlled monospace fonts - Minitab for example. Of these four applications, R and SAS were clearly superior to SPSS and the standard edition of Minitab. ( Godfrey and Loots 2014) gave more detailed scrutiny of R, SAS ( SAS Institute Inc.

It is true that some add-on packages for R also generate unreadable output, but as illustrated below, this is less of an issue than for software like SPSS or Minitab. As a guide, if the individual text in a window cannot be highlighted using the keyboard and not the mouse, then it is likely that this text will not be read for the blind user. The speech output software used by blind people can only interpret information that is text. 2014) is a prime example of the worst possible presentation of information that was originally text this product generates graphics that include text which is not readable by a blind person for all of its statistical output. The output from Minitab Express ( Minitab Inc. 2012) is an example of this, and to a lesser extent so is the standard edition of Minitab ( Minitab Inc. Many software applications are making use of graphics when once the information would be presented in text form with an accompanying graph. Many of the problems blind people face are a consequence of the failure of the specialist screen reading software we use to interact with graphical user interfaces.
