摘要： Disclosed is an apparatus and method for combating light sensitivity, or photophobia, for people with low vision. Both the apparatus and method filter particular wavelengths of light associated with photophobia. This filtering is achieved while maintaining a luminance that is acceptable to the user and that maintains contrast. The apparatus of the disclosure is a mechanical filter that can be applied over an electronic screen. The method utilizes software and a filtering module associated with either the CPU or GPU of a computer. The filtering module processes a video signal by eliminating certain targeted wavelengths of light.

摘要： 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.

摘要： Disclosed is a tablet with an improved Braille display. The Braille display employs a pin array that allows for the selective use of either six or eight pin cells. This is accomplished by turning off or on a pin pair adjacent to each cell. The spacing of the pins also allows capacitive sensors to be located adjacent to each Braille cell. These sensors are used to determine the location of the user's finger upon the display. The pin spacing further allows geometric shapes to be generated in additional to text.

摘要： Disclosed is a braille display that is impact resistant and that employs a modular construction. The impact resistance is achieved, in part, by molded and resilient end caps. Each end cap includes a centrally positioned slit that functions in absorbing lateral impacts to the display. The impact resistance is further achieved by an over molded housing that is positioned about an associated USB connector. The modularity of the display is achieved by way of a subassembly that is releasably secured within the interior of a main housing. The subassembly, in turn, includes a series of cell compartments that are arranged in groups. Each group of cell compartments is controlled by an individual shift register. This allows a grouping cell compartments to be removed and replaced as needed without disturbing the remaining cell components.

摘要： Techniques for programmatically magnifying one or more visible content elements of at least one markup language document, so as to increase the display size of those visible content elements. A magnification facility may be configured to apply multiple different zoom techniques. The magnification facility may be configured to evaluate the markup language document(s) at a time that the document(s) are being processed for display to select which of the multiple different zoom techniques may be applied at a time to increase a display size of visible content elements relative to a default display size for those elements. The magnification facility may be incorporated within the markup language document(s) and executed by a viewing application that processes markup language documents. For example, the markup language document(s) may form a web page and the magnification facility may be implemented as scripting language code incorporated into the document(s) of the web page.

摘要： Mechanisms to allow a user to flexibly display visual content on multiple display devices connected to a computer. Each of the multiple displays may be configured to display a portion of visual content from a computer desktop or from an external content source. Each portion of visual content to be outputted may first be enhanced, such as via magnification, before being displayed on one of the multiple display devices. The user may be provided with a first control that enables the user to adjust a portion of visual content displayed on a first display device independently of a portion of visual content displayed on a second display device. A second control may also be provided that enables the user to adjust the portion of visual content displayed on the second display device independently of the portion of visual content displayed on the first display device.

摘要： A screen reader software product feature referred to as a custom summary view, or custom summary, has been developed. The custom summary feature solves the major problem faced by blind users when working with large sets of data. That problem occurs as a result of an inefficiency of gleaning important data from within these larger sets. The custom summary provides the ability to gather such data into a summary that can be navigated easily. This ease of navigation greatly levels the playing field in the competitive workplace for blind workers and students alike. Also taught is a feature, referred to as a multiple region support, which allows users to define blocks of contiguous cells containing data as “regions” when a document such as a spreadsheet is displayed by a screen reader. Regions can either be named by the user or be defined simply by the top left and bottom right cell addresses that represent the boundaries of the block of contiguous cells containing data.

摘要： Some described embodiments relate to techniques for editing markup elements of a markup language document to emphasize a portion of the visible content elements of the markup language document. The techniques may be implemented in any suitable manner, including via scripting language code (e.g., JavaScript) that is incorporated into the markup language document but is not preconfigured with information regarding the markup language document or any other markup language document. The scripting language code may perform the editing automatically, and based on an automatic analysis of markup elements of the markup language document. Some embodiments may include determining the portion of the markup language document to be emphasized by identifying content of interest to a user, including by determining a set of related content through analyzing a structure of markup elements of the markup language document and/or layout of visible content elements of the markup language document.
