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.

Techniques for programmatic magnification of visible content elements of markup language documents

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.

Emphasizing a portion of the visible content elements of a markup language document

Identifying a set of related visible content elements in a markup language document

Display screen with icon

Embodiments of techniques for moving visible content elements of at least one markup language document within a display area in response to user input moving a cursor of a pointing device. Visible content elements of the markup language document may be moved in a display area based at least in part on an amount by which a content area that includes the visible content elements extends outside of the display area. For example, a panning facility may determine an amount by which to shift visible content elements in the display area based at least in part on an amount by which a content area that includes the visible content elements extends beyond the display area. The panning facility may move the visible content elements by instructing a viewing application to scroll the visible content elements within the display area.

Panning a content area of a markup language document based on movements of a cursor of a pointing device

In a computer system receiving input from a user via at least a keyboard and a pointing device, in which input via the pointing device causes corresponding movement of a pointing image on a display screen of the computer system, user input may be received via the pointing device to point the pointing image at an onscreen object on the display screen. In response to the user activating a key on the keyboard while the pointing image is pointing at the onscreen object, a secondary action with respect to the onscreen object may be executed.

Executing secondary actions with respect to onscreen objects

In a computer system having a display screen configured to display visual content, a plurality of techniques may be identified to be considered for enhancing visual accessibility of a particular collection of visual content to be displayed to an end user on the display screen. For each technique, an algorithm may be applied to compute one or more measures of health of the display of the particular collection of visual content resulting from applying the respective technique to enhance the visual accessibility of the particular collection of visual content. Based at least in part on the computed measures of health, one or more best techniques may be selected and applied to enhance the visual accessibility of the particular collection of visual content. The enhanced particular collection of visual content may be displayed to the end user on the display screen.
