Abstract

A method of automatically partitioning a refreshable braille display based on presence of pertinent ancillary alphanumeric content. In an unpartitioned configuration, every braille cell of the refreshable braille display is used to output the primary alphanumeric content. When the refreshable braille display outputs a segment of the primary alphanumeric content having associated ancillary alphanumeric content, such as a footnote or a comment, the braille display is automatically partitioned into a first partition and a second partition. The braille cells of the first partition are allocated for outputting the primary alphanumeric content, while the braille cells of the second partition are allocated for outputting the ancillary alphanumeric content.
