Claim:
1. A method of dynamically advancing a refreshable braille display, the method comprising the steps of: providing a braille display in communication with a non-transitory tangible computer-readable medium having computer-executable instructions for outputting an electronic document; setting a default auto-update interval for the braille display; outputting a portion of the electronic document onto the braille display as a current line of braille characters; determining whether the current line ends with a blank braille cell; responsive to determining that the current line ends with the blank braille cell, calculating a current auto-advance interval for the current line as a function of a number of used cells within the current line and the default auto-update interval; and automatically outputting a next line of braille characters after the current auto-advance interval has lapsed.
