User interaction of a visually displayed document is provided via a graphical user interface (GUI). The document includes, and is parsed into, a plurality of text-based grammatical units. An input device modality is selected from a plurality of input device modalities which determines the type of input device in which a user interacts with to make a selection. One or more grammatical units of the document are then selected using the selected type of input device. Each grammatical unit that is selected is read aloud to the user by loading the grammatical unit into a text-to-speech engine. The text of the grammatical unit is thereby automatically spoken. Furthermore, a switching modality is selected from a plurality of switching modalities. The switching modality determines the manner in which one or more switches are used to make a selection. Using the selected switching modality, a user steps through at least some of the grammatical units in an ordered manner by physically activating one or more switches associated with the GUI. Each activation steps through one grammatical unit. Each grammatical unit that is stepped through is read aloud by loading the grammatical unit into a text-to-speech engine, thereby causing the text of the grammatical unit to be automatically spoken.

One aspect of the present invention includes adaptive techniques used to render dynamic web content for accessibility software applications, such as screen readers. In one embodiment, an operation for improving webpage browsing with accessibility software includes detecting if an accessibility software application is in use, tracking the position of user focus on the webpage, and presenting information to the user based on the position of user focus on the webpage. In a further embodiment, additional content is rendered on the webpage to screen reader applications, and is placed at the position of the screen reader focus in response to dynamic content appearing or changing on the webpage. This additional content is read by the screen reader to inform the user of the dynamic content change, and/or enable the user to quickly perform a specific action on the webpage.

A system for providing DHTML (“Dynamic Hyper-Text Markup Language”) accessibility. Rich keyboard and other assistive technology (“AT”) accessibility is provided for sophisticated Web applications. When a user downloads a Web page, the system performs initialization that includes loading at least one display object, and binding the object to a predetermined event, such as, for example, a focus event. The event the object is bound to may be any semantic, device independent event. The disclosed system may also load a device handling function, such as a keyboard handling function. The device handling function associates one or more display objects with corresponding device actions, such as key presses. A keyboard handling function may operate to intercept at least one key press, and determine that an intercepted key press matches a key press corresponding to a previously loaded display object. The device handling function may create a focus event for the previously loaded display object, and post the event to the display object. The display object then handles the event by visually responding to the intercepted key press, for example by changing the visual representation of the display object to be highlighted, or to otherwise indicate that the display object has been selected. The event may then also be sent to an assistive technology program, such as a screen reader program. Using the values of attributes in that display object, such as the value of the role attribute, the assistive technology program responds to the event as appropriate.

The invention discloses a touch screen-based rotary type continuous speed changing browsing and searching method, belonging to the information technical field; with the method, a user can make continuous operations in the limited ranged of the touch screen, achieving the control on an object in an approximate limitless range.

A screen magnification application for visually impaired users automatically sets the visual focus and magnification level on a web page element according to end-user selection.

A method, system, and computer program product is disclosed for customizing a synthesized voice based upon audible input voice data. The input voice data is typically in the form of one or more predetermined paragraphs being read into a voice recorder. The input voice data is then analyzed for adjustable voice characteristics to determine basic voice qualities (e.g., pitch, breathiness, tone, speed; variability of any of these qualities, etc.) and to identify any “specialized speech patterns”. Based upon this analysis, the characteristics of the voice utilized to read text appearing on the screen are modified to resemble the input voice data. This allows a user of the system to easily and automatically create a voice that is familiar to the user.

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.

A browser, with a web page screen-reading function, displays a web page easy to read in synchronism with text screen-reading is possible. The browser determines whether lateral scroll during normal page displaying is occurred reduces, if occurred, the width of displayed component of the display page below the width of the display area and displays the component to be displayed within reduced area to reconstruct the layout of page. The browser, thus, conducts the reconstructed page displayed and vertical scroll so that the character string corresponding to the screen-read part aurally outputted can be displayed.
