The attendance was once multidisciplinary, together with researchers from the fields of know-how, drugs and psychology and representatives from businesses keen on the rehabi­ litation of the visually impaired. 5 technical periods have been prepared, facing the next themes: automated construction of Braille and platforms for paperless Braille, aids for interpreting and for the interplay with coded informa­ tion resources, low imaginative and prescient aids, transduction of visible infor­ mation right into a tactile illustration, mobility aids. 3 diversified program sectors have been mostly thought of: schooling and tradition, vocational education, mobility. a last consultation was once dedicated to a dialogue in operating teams. the implications are in brief defined within the following concise file of the Workshop.

It is therefore necessary to provide enough space like additional benches, large tables and drawers to prevent the piling up of documents as much as possible. Hardware ergonomics, input devices: Using braille information imposes a di fferent human factor design of the input equipment. While the hands are used for reading as well as for input of data there has to be either a sequential action pattern or a one-hand reading and one-hand keyboard operation.

The figures of the second number are shifted downwards within the Braille cell by one line. In general the projection is not quite as simple as for fractions but the clear structure of mathematical formulas nevertheless provides for clear production rules. The line onto which the current text is written is called the "base line".

In the next line it is not correct to use the contraction for 'richt' because "Trichter" has a completely different meaning.
