  • Patent number: 11709898
    Abstract: A screen reader application traverses each node in a document object model (DOM) for the text stylization. Properties for foreground color, background color, font type, font size and font stylization are algorithmically reduced to an identifier. Each node in the DOM with the same identifier has the same text stylization. Unique and infrequent text stylizations by a webpage author signal a point of interest. The screen reader application locates and navigates to that node in the DOM on behalf or in response to the end user. Points of interest are further identified by a number of additional factors. A first includes percentage of text of having the text stylization versus total text in the DOM. A second includes excluding candidate point of interest nodes having more than 250 characters. Others include imposing minimum font sizes and text contrast ratios to qualify as a point of interest.

  • Patent number: 10971034
    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.
