Screen readers enable visually impaired people to access information provided by computer systems. They gather data from operation system and applications, govern the data in an internal data structure (off-screen model), and provide the information in an appropriate format to output devices. However, current approaches for the construction of off-screen models are not appropriate for tactile graphical displays. Within this paper we therefore describe the composition of an alternative off-screen model appropriate for storing and administrating information necessary for tactile graphical displays.
