Abstract:
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.
Abstract:
In a computer system having originating software configured to provide visual content for display on a display screen and enhancement software configured to apply enhancements to the visual content for display on the display screen, the visual content may be magnified, via the enhancement software, to a magnification level different from a size at which the visual content is provided by the originating software. In response to an instruction to change the magnification level, the magnification level to which the visual content is magnified via the enhancement software may be changed, and one or more enhancements, other than magnification, applied to the visual content via the enhancement software may also be changed.
Abstract:
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.
Abstract:
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.
