Abstract
In an apparatus as a working aid for blind and partially sighted people for communication with a computer system with a keyboard and with a screen output for a screen as an output device for determining a raster coordinate point of said screen output and for producing an electrical data signal corresponding to said coordinate point for the repeat and reliable finding of a particular information corresponding to a certain coordinate point, at least two data call-up devices are provided capable of calling up the data corresponding to a certain coordinate point in the form of only end position-stable sliders movable independently of one another in two coordinate directions perpendicular to one another. Thus defining by the relative coordinate position the certain coordinate point, one of the sliders being arranged above or below and one of the sliders being arranged to one of the sides of said keyboard, a position detection device is provided at each slider for supplying an electrical signal corresponding to the displacement path of each slider along one of the coordinate directions being subdivided in raster sections. The call-up devices having a data call-up release device to call up the converted read-out data corresponding to the certain coordinate point at a desired moment.
