Claim One:
1. A method for operating a refreshable Braille display comprising a touch-and-sense surface having a plurality of neighboring Braille cells which are suitable for displaying Braille characters, the method comprising the steps of: a) receiving a string of characters of a character encoding system, b) assigning the string of characters to a drive signal specifying the activation or deactivation of a tuple of dots which are raised through holes in the touch-and-sense surface upon activation and which are retracted upon deactivation, c) driving the refreshable Braille display by communicating the drive signal for activating or deactivating the tuple of dots, which are arranged in at least one Braille cell of the Braille display, wherein the drive signal is configured to activate and/or to deactivate the tuple of dots so as to generate a dynamic tactile display of said single string of characters, and wherein the time dependent characteristic of activation and/or deactivation of the tuple dots is defined by the string of characters.
