The graphics-enabled display for blind computer users

Funded by the German Federal Ministry of Economics and Technology (Bundesministerium für Wirtschaft und Technologie, BMWi), HyperBraille is a project engaged in developing a touch-sensitive tablet display for blind and partially sighted users.
This pin-matrix display drastically increases the amount of information perceivable to blind computer users through both hands, and enables them to experience spatial structures and graphic symbols as additional information. Ideally, objects such as text blocks, tables, menus and other elements of the Windows user interface can be fully mapped to the pin-matrix display. Moreover, geometric drawings, floor plans, diagrams and other information can be made accessible to visually impaired students in teaching.
Developing the software required to control the tablet display is a major part of the HyperBraille project, which focuses mainly on all standard Office and Internet applications.
