Abstract: The invention relates to a data input/read-out device, including at least one output element, more particularly a Braille element, for outputting Braille data by correspondingly changing the surface profile; and at least one input element for inputting data, the input element being positionable in at least two different positions to thus enter data wherein the maximum spacing between the at least one input element and the at least one output element does not exceed a specific maximum value so that the input element and the output element can be touched or actuated simultaneously by one hand.

Abstract: The information inspection system for data-processing equipment for the obtaining of electric signals representing auditory, visual and/or tactile information for vision-impaired typists has an interface which "listens-in" in the data bus of an electronic computer or an automated typewriter and thus scans the transmitted data practically without power and without affecting the operation of the data-processing equipment, and feeds same to the end device for the vision-impaired where they are presented in visual, auditory and/or tactile form. No special modification of the hardware and/or software of the data-processing equipment, and therefore of the automated typewriter or the electronic computer, is necessary.
