This application claims a priority benefit, under 35 U.S.C. §119(e), to U.S. Provisional Application No. 61/697,054, entitled “Enhanced Accessibility Technologies,” filed Sep. 5, 2012, under attorney docket no. A0944.70003US00, which is incorporated herein by reference in its entirety.
BACKGROUNDWith regard to computer systems, “accessibility” refers to the extent to which a computer resource (e.g., hardware, software applications, output content, etc.) is usable by people of all abilities and disabilities. In particular, a focus of recent effort has been on making computer content accessible to users with visual impairments. Accessibility Technology (AT) software applications, such as screen magnifiers and screen readers, have been and are continuing to be developed to provide enhancements to visual content on computer displays to make the visual content easier for visually impaired users to consume.
Some AT applications provide multiple options for enhancements that a visually impaired user could select to be applied to visual content to make it more accessible. One common type of enhancement is magnification, by which the visual content is enlarged to make it easier to see. Another type of enhancement is color enhancement, by which color of the visual content (e.g., background color, foreground color, reverse contrast, etc.) is adjusted to make the visual content easier to see. Other types of enhancement include pointer/cursor/focus enhancements, including various visual indicators of the current position of the mouse pointer, text cursor, input focus, etc. Yet another type of enhancement is text-to-speech or Braille display, by which visual content is converted to audio or tactile information that a (blind) user can consume.
An example of a typical way of making enhancement options available to a user is illustrated in
One type of embodiment is directed to a method 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 method comprising: magnifying the visual content, via the enhancement software, to a magnification level different from a size at which the visual content is provided by the originating software; and in response to an instruction to change the magnification level, changing the magnification level to which the visual content is magnified via the enhancement software, and changing one or more enhancements, other than magnification, applied to the visual content via the enhancement software.
Another type of embodiment is directed to at least one computer-readable storage medium storing computer-executable instructions that, when executed, perform a method 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 method comprising: magnifying the visual content, via the enhancement software, to a magnification level different from a size at which the visual content is provided by the originating software; and in response to an instruction to change the magnification level, changing the magnification level to which the visual content is magnified via the enhancement software, and changing one or more enhancements, other than magnification, applied to the visual content via the enhancement software.
Another type of embodiment is directed to a computer system comprising at least one processor, and at least one storage medium storing originating software configured to provide visual content for display on a display screen, and storing processor-executable instructions that, when executed by the at least one processor, perform a method comprising: magnifying the visual content for display on the display screen, to a magnification level different from a size at which the visual content is provided by the originating software; and in response to an instruction to change the magnification level, changing the magnification level and changing one or more enhancements, other than magnification, applied to the visual content for display on the display screen.
The accompanying drawings are not intended to be drawn to scale. In the drawings, each identical or nearly identical component that is illustrated in various figures is represented by a like numeral. For purposes of clarity, not every component may be labeled in every drawing. In the drawings:
The inventors have recognized that conventional ways of providing access to enhancements for visual content in computer systems, such as the example conventional user interface illustrated in
The inventors have recognized that advantages over the foregoing conventional techniques may be realized through novel techniques that automatically apply settings for one or more other enhancements when the user specifies the magnification level to be applied to visual content for display in a computer system. The inventors have appreciated that in some embodiments, by tying one or more other enhancements to the magnification level, a user interface for applying the enhancements may be simplified and present fewer buttons, settings, etc., for a user to learn to use.
Accordingly, some embodiments described herein relate to techniques for applying enhancements to visual content in dependence upon the magnification level, which techniques may address one or more of the above-discussed shortcomings of traditional methods, and/or may provide one or more of the foregoing benefits. However, aspects of the invention are not limited to any of these benefits, and it should be appreciated that some embodiments may not provide any of the above-discussed benefits and/or may not address any of the above-discussed deficiencies that the inventors have recognized in conventional techniques.
In some embodiments, in response to an instruction to change the magnification level applied to visual content, one or more other enhancements may be changed automatically, in addition to changing the magnification level. In some embodiments, a particular enhancement may become activated at a particular magnification level, when it was not activated at another magnification level. Alternatively or additionally, in some embodiments a parameter of a particular enhancement may be varied in correlation with the magnification level. For example, in some embodiments an enhancement may be made stronger, more prominent, etc., when the magnification level is increased. As used herein, the term “magnification level” refers to a multiple of the original pixel size of onscreen content that is magnified. A single pixel from the original display, for example, would appear twice as large and would require 4 pixels to display at a 2× magnification level. For techniques that do not apply the same magnification to all of the content being enhanced, the magnification level refers to the maximum level of magnification applied to some content being enhanced. For example, in some embodiments, magnification may be applied preferentially to content that is deemed important (such as the main text of a document) while other less important content (such as menu bars, navigational controls, etc.) may be magnified to a lesser degree or may be left unmagnified or even made smaller. In such cases, the “magnification level” refers to the highest level of magnification applied (i.e., to the important content).
In some embodiments, a user interface for providing access to enhancements for visual content may include a single-input control, such as a slider, that allows the user to specify the magnification level along with the corresponding automatic settings for one or more other enhancements. In some embodiments, this control may replace a more extensive user interface having individual controls for individual enhancements. In other embodiments, such a more extensive user interface may also be provided as an alternative for users who wish to have access to it. In some embodiments, one or more enhancements may be tied to the magnification level and controlled via the single-input control, while one or more other enhancements may be provided via one or more different user interface elements, instead of being tied to the magnification level.
It should be appreciated that the foregoing description is by way of example only, and aspects of the invention are not limited to providing any or all of the above-described functionality, although some embodiments may provide some or all of the functionality described herein.
The aspects of the present invention described herein can be implemented in any of numerous ways, and are not limited to any particular implementation techniques. Thus, while examples of specific implementation techniques are described below, it should be appreciated that the examples are provided merely for purposes of illustration, and that other implementations are possible.
One illustrative application for the techniques described herein is for use in a computer system 100 operated by a (human) user 102. An exemplary operating environment for such a system is illustrated in
Exemplary computer system 100 may receive input from user 102 via one or more input devices such as keyboard 106 and/or pointing device 108, and may provide output to user 102 via one or more output devices such as display screen 104. Any suitable type(s) of display screen, keyboard, pointing device, and/or other input and/or output device(s) may be used, as aspects of the invention are not limited in this respect. Display screen 104 may be any type of display component capable of presenting visual content to user 102, and need not be two-dimensional.
Input and/or output devices such as display screen 104, keyboard 106, and pointing device 108 need not be separate physical devices, but in some embodiments may be integrated in any suitable combination, such as in a touchscreen-type apparatus that combines display screen, keyboard, and/or pointing device functionality. In addition, while a single display screen, keyboard, and pointing device are referred to herein for simplicity, some embodiments may make use of multiple display screens, keyboards, and/or pointing devices to provide equivalent and/or similar functionality.
In the example depicted in
While web browser 110 and AT application 114 are provided as examples of applications that may be run on computer system 100, it should be appreciated that aspects of the invention are not limited to the inclusion of either or both of web browser 110 and AT application 114. Furthermore, while AT application 114 is provided as a particular example of a component of computer system 100 (e.g., a software application) that may provide functionality described herein (e.g., to apply enhancements to visual content), it should be appreciated that aspects of the invention are not limited to being performed by an AT application. In particular, while providing enhancements designed to improve accessibility may be one beneficial exemplary use of the techniques described herein, some embodiments are not limited to accessibility technology, and the techniques described herein may be applied to any suitable type(s) of enhancements to visual content provided by any suitable type(s) of application and/or component.
In some embodiments, AT application 114 may be configured to operate (e.g., via execution of a set of instructions by the one or more processors of computer system 100) to apply enhancements to visual content that is provided for display on display screen 104 by AT application 114 itself and/or by other components such as web browser 110 and/or other applications 116 (including, for example, the operating system of computer system 100). For instance, in one particular example, web browser 110 may provide visual content (e.g., text, images, user interface elements, etc., included in a web page) for display on display screen 104 at a particular default size, and AT application 114 may process the visual content provided by web browser 110 to apply one or more enhancements (e.g., magnification and/or one or more other accessibility enhancements) to the visual content before it is displayed. In such embodiments in which a component (such as AT application 114 or a non-AT component configured to provide functionality described herein) operates to apply enhancements to visual content provided for display by another component (such as, for example, web browser 110, another application 116, an operating system of computer system 100, etc.), the component originally providing the visual content for display is referred to herein as the “originating” component, and the component applying the enhancements to the visual content provided by the originating component is referred to herein as the “enhancement” component.
It should be appreciated that in embodiments in which the functionality described herein is provided by AT application 114 (or a non-AT component configured to provide functionality described herein) running on computer system 100, the functionality may be performed with respect to visual content generated and/or otherwise provided by any suitable component(s) of computer system 100 (including visual content generated by AT application 114 itself), and computer system 100 need not include any particular other components such as web browser 110. In embodiments in which a web browser 110 is included in computer system 100, web browser 110 may be configured (e.g., programmed) to provide access to web pages by downloading a web page 122 from a web server 120, executing the code of web page 122 to render web page 122 visually, and displaying the rendered web page 122 on display screen 104.
In some embodiments, as discussed above, visual content provided by web browser 110, either as part of a rendered web page or as part of the browser tool itself (e.g., browser menu items, buttons on a browser toolbar, etc.), may be enhanced by AT application 114 (or a non-AT component of computer system 100 configured to provide functionality described herein) for display on display screen 104. Alternatively or additionally, in some embodiments web browser 110 may have its own AT module 112 (e.g., a set of instructions) configured to cause web browser 110 to operate (e.g., via execution of the instructions by the one or more processors of computer system 100) to apply enhancements to visual content in any of the manners described herein. In such embodiments, for example, web browser 110 (or suitable components of web browser 110 other than AT module 112) may function as originating software for the visual content, and AT module 112 may function as enhancement software with respect to that visual content. While AT module 112 is provided as one particular example of a suitable component for providing functionality described herein, it should be appreciated that some embodiments are not limited to accessibility applications, and a similar non-AT module could also be used.
Alternatively or additionally, in some embodiments visual content included in web page 122 may be enhanced by execution of AT code 124 (e.g., one or more instructions) embedded within web page 122 itself. In some embodiments, when web browser 110 executes the code of web page 122, including AT code 124, to render web page 122 for display on display screen 104, the execution of AT code 124 may cause web browser 110 to apply enhancements to visual content within the rendered web page in accordance with techniques described herein. In such embodiments, for example, suitable portions of web page 122 (e.g., as interpreted/executed by web browser 110), other than AT code 124, may function as originating software for the visual content, and AT code 124 (e.g., as interpreted/executed by web browser 110) may function as enhancement software with respect to that visual content. While AT code 124 is provided as one particular example of a suitable delivery mechanism for the functionality described herein, it should be appreciated that some embodiments are not limited to accessibility applications, and similar non-AT code could also be used.
In some embodiments, applying enhancements to visual content provided by any component of computer system 100 may involve downloading an AT resource 132 to computer system 100 from an AT server 130. For example, in some embodiments, AT application 114 and/or web browser 110 (e.g., as directed by instructions contained in AT module 112 and/or AT code 124) may query AT server 130 for enhancements to be applied to certain visual content, to certain web pages, etc., and/or for instructions as to how to apply enhancements (e.g., as to application of enhancements in accordance with techniques described herein). Thus, for example, AT resource 132 may comprise an indication of one or more enhancements to apply, an indication of one or more mappings of enhancements to visual content to implement, a script (e.g., a set of instructions) to execute, and/or any other suitable resource to enable functionality described herein. In some instances, AT resource 132 may function as enhancement software for visual content provided by other originating software. While AT server 130 and AT resource 132 are provided as particular examples for a suitable delivery mechanism for functionality described herein, it should be appreciated that some embodiments are not limited to accessibility applications, and similar non-AT resources could be used.
It should be appreciated from the foregoing that not all components illustrated in
In some embodiments, as discussed above, one or more enhancements may be applied to visual content for display on a display screen in a computer system. For illustration,
On the exemplary display screen 300 of
As used herein, the term “single-input control” refers to any suitable user interface element that allows for user control of the magnification level and causes corresponding automatic changes to one or more other enhancements, without requiring any additional input from the user other than the input to control the magnification level. For example, when the single-input control is a graphical slider such as slider 340, the user may specify the magnification level by dragging the slider with the mouse (or other input device used to control the slider), and in some embodiments one or more other enhancements may be changed in response to this user instruction to change the magnification level, without requiring any additional input from the user. In some embodiments, the single-input control may be labeled with particular magnification levels, or may provide any other suitable indicator to the user that an effect of using the control will be to change the magnification level, and/or may provide any other suitable indicator of the particular magnification level that will result from the user's operation of the control in a particular way. However, in other embodiments, the manner in which the control is presented to the user may not indicate that it is for purposes of magnification, or may provide any suitable indication that the control may have effects other than magnification. For example, in some embodiments the single-input control may be presented as a “see it better” control, or in any other suitable way as a control operable to increase accessibility of the visual content on the display screen in ways not limited to magnification. It should be appreciated that the foregoing description is provided merely for purposes of exemplary illustration, and aspects of the invention are not limited to any particular form of implementation of a single-input control.
In the example of
In the example illustrated in
As can be seen from the example in
Any suitable type(s) of enhancements may be applied to visual content in conjunction with magnification, as aspects of the invention are not limited in this respect. Non-limiting examples of suitable enhancements include color enhancements (e.g., background color change, foreground color change, contrast change, etc.), cursor enhancements (e.g., circles, triangles, colors, etc., applied to the cursor), pointer enhancements (e.g., circles, crosshairs, colors, etc., applied to the pointer), focus enhancements (e.g., outlining around input fields, menu items, dialog options, toolbar controls, other controls, etc., having input focus), enhancement of a selected range of information (e.g., highlighted or otherwise selected text, selected spreadsheet cells, etc.), font enhancements (e.g., boldness), speech output (e.g., screen reading, text-to-speech for visual content that the user selects, navigates to, or hovers over with the pointer), tactile output (e.g., Braille output for visual content that the user selects, navigates to, or hovers over with the pointer), animation effects, etc.
In some embodiments, a different setting or set of settings may be applied to the available enhancements at one magnification level than at another magnification level. For example, in some embodiments, a setting for enhancements at a particular magnification level may have zero, one, or more of the other available enhancements activated at that magnification level, and the remaining enhancements not activated. At another magnification level, more, fewer, and/or different ones of the available enhancements may be activated. In one particular example, additional enhancements may be activated at increasing magnification levels. This was demonstrated in the example of
The determination of which enhancements activate using which parameter settings at which magnification levels may be made in any suitable way, as aspects of the invention are not limited in this respect. In some embodiments, enhancement settings may differ for different computer systems, for visual content provided by different originating software applications, and/or for different users. In some embodiments, a particular user may specify (e.g., by inputting appropriate settings) one or more enhancement settings that the user desires to be automatically applied at one or more particular magnification levels. Alternatively or additionally, in some embodiments the enhancement software may be programmed with particular enhancement settings to automatically apply at particular magnification levels for particular users or types of users. Such settings may be determined in any suitable way, including by determining the statistical needs of one or more user groups at various magnification levels, such as by conducting surveys or monitoring typical user interaction with conventional enhancement settings to determine the statistical needs of one or more user groups.
It should be appreciated from the foregoing that one embodiment of the invention is directed to a method 400 for applying enhancements to visual content, as illustrated in
It should be further appreciated from the foregoing that another embodiment of the invention is directed to a method 500 for applying enhancements to visual content, as illustrated in
At act 530, a determination may be made as to whether the magnification level has been changed, e.g., by the user or by a program instruction. While the magnification level remains unchanged, method 500 may loop at act 520 to continue to monitor. When the magnification level is changed, a notification may be generated, and may be received by the registered observers. At act 540, each observer (e.g., via the observer's handler) may map the new magnification level (together with any relevant user-specific settings, application-specific settings and/or system-specific settings) to the appropriate settings (e.g., activation on or off, and/or parameter settings) for the observer's assigned enhancement. At act 550, the enhancement software may apply the new magnification level, as well as the enhancement settings determined by the registered observers for that magnification level, to the visual content for display on the display screen. Method 500 then loops back to act 520 to monitor for further changes to the magnification level.
It should be appreciated that the foregoing description is provided by way of example only, and other implementations are possible. For example, other mechanisms for reacting to changes in the magnification level may be used, including but not limited to polling to check for magnification level changes, or controlling the available enhancements from within the magnification code.
A computer system in accordance with the techniques described herein may take any suitable form, as aspects of the present invention are not limited in this respect. An illustrative implementation of a computer system 600 that may be used in connection with some embodiments of the present invention is shown in
