A Graphical Tactile Screen-Explorer

A graphical screen explorer, as it is developed in the HyperBraille project, has different demands on representing information than conventional screen readers and thereby new concepts of interaction, the representation of widgets and the synchronization of multimodal operations become necessary. We describe a concept for complex user interaction with tactile widgets and how to adapt the screen explorer to the requirements of third party applications by the use of Add-Ins.
