Chapter 24 Accessibility 1251 24.15 Accessibility in Microsoft Windows 2000 Because of the prominence of the Windows operating system, it is crucial that this operating system provide proper accessibility to individuals with disabilities. Beginning with Microsoft Windows 95, Microsoft has included accessibility features in its operating systems and many of its applications, including Office 97, Office 2000 and Netmeeting. In Microsoft Windows 2000, Microsoft significantly enhanced the operating system s accessibility features. All the accessibility options provided by Windows 2000 are available through the Accessibility Wizard, which guides users through Windows 2000 accessibility features and then configures users computers in accordance with the chosen specifications. This section uses the Accessibility Wizard to guide users through the configuration of their Windows 2000 accessibility options. To access the Accessibility Wizard, users computers must be equipped with Microsoft Windows 2000. Click the Start button and select Programs, followed by Accessories, Accessibility and Accessibility Wizard. When the wizard starts, the Welcome screen displays. Click Next. The next dialog (Fig. 24.22) asks the user to select a font size. Modify the font size if necessary and then click Next. Figure 24.22 depicts the Display Settings dialog. This dialog allows the user to activate the font-size settings chosen in the previous window, change the screen resolution, enable the Microsoft Magnifier (a program that displays an enlarged section of the screen in a separate window) and disable personalized menus. Personalized menus hide rarely used programs from the start menu and can be a hindrance to users with disabilities. Make appropriate selections and click Next. The Set Wizard Options dialog (Fig. 24.23) asks questions about the user s disabilities; the answers to these questions allow the Accessibility Wizard to customize Windows to better suit the user s needs. For demonstration purposes, we selected every type of disability included in the dialogue. Click Next to continue. Fig. 24.22 Fig. 24.22Fig. 24.FF22ig. 24.22ig. 24.22Display Settings dialog.

1250 Accessibility Chapter 24 braille keyboards are combined with a speech synthesizer or a braille display, enabling users to interact with the computer to verify that their typing is correct. Speech synthesis also provides benefits to people with disabilities. Speech synthesizers have been used for many years to aid people who are unable to communicate verbally. However, the growing popularity of the Web has prompted a surge of interest in the fields of speech synthesis and speech recognition. Now, these technologies are allowing individuals with disabilities to use computers more than ever before. The development of speech synthesizers also is enabling the improvement of other technologies, such as VoiceXML and AuralCSS (www.w3.org/TR/REC-CSS2/aural.html). These tools allow people with visual impairments and illiterate people to access Web sites. Despite the existence of adaptive software and hardware for people with visual impairments, the accessibility of computers and the Internet is still hampered by the high costs, rapid obsolescence and unnecessary complexity of current technology. Moreover, almost all software currently available requires installation by a person who can see. Ocularis is a project launched in the open-source community that aims to address these problems. (Open-source software for people with visual impairments already exists; although it is often superior to its proprietary, closed-source counterparts, it has not yet reached its full potential.) Ocularis ensures that the blind can access and use all aspects of the Linux operating system. Products that integrate with Ocularis include word processors, calculators, basic finance applications, Internet browsers and e-mail clients. In addition, a screen reader is included for use with programs that have a command-line interface. The official Ocularis Web site is located at ocularis.sourceforge.net. People with visual impairments are not the only beneficiaries of efforts to improve markup languages. People with hearing impairments also have a number of tools to help them interpret auditory information delivered over the Web. One of these tools, Synchronized Multimedia Integration Language (SMIL ), is designed to add extra tracks (layers of content found within a single audio or video file) to multimedia content. The additional tracks can contain closed captioning. Technologies are being designed to help people with severe disabilities, such as quadriplegia, a form of paralysis that affects the body from the neck down. One such technology, EagleEyes, developed by researchers at Boston College (www.bc.edu/ eagleeyes), is a system that translates eye movements into mouse movements. A user moves the mouse cursor by moving his or her eyes or head and is thereby able to control the computer. GW Micro, Henter-Joyce and Adobe Systems, Inc., also are working on software that assists people with disabilities. Adobe Acrobat 5.0 complies with Microsoft s application programming interface (API) to allow businesses to provide information to a wider audience. JetForm Corp is also accommodating the needs of people with disabilities by developing server-based XML software. The new software allows users to download information in a format that best meets their needs. There are many services on the Web that assist e-businesses in designing Web sites so that they are accessible to individuals with disabilities. For additional information, the U.S. Department of Justice (www.usdoj.gov) provides extensive resources detailing legal and technical issues related to people with disabilities.

One such technology, Microsoft s Active Accessibility , establishes a protocol by which an accessibility aid can retrieve information about an application s user interface in a consistent manner. Accessibility aids require information such as the name, location and layout of particular GUI elements within an application, so that the accessibility aid can render the information properly to the intended audience. Active Accessibility also enables software developers and accessibility-aid developers to design programs and products that are compatible with each other. Moreover, Active Accessibility is packaged in two components, enabling both programmers and individuals who use accessibility aids to employ the software. The Software Development Kit (SDK) component is intended for programmers: It includes testing tools, programmatic libraries and header files. The Redistribution Kit (RDK) component is intended for those who use accessibility aids: It installs a runtime component into the Microsoft operating system. Accessibility aids use the Active Accessibility runtime component to interact with and obtain information from any application software. For more information on Active Accessibility, visit: www.microsoft.com/enable/msaa Another important accessibility tool for individuals with visual impairments is the braille keyboard. In addition to providing keys labeled with the letters they represent, a braille keyboard also has the equivalent braille symbol printed on each key. Most often,

1248 Accessibility Chapter 24 24.13 JAWS for Windows JAWS (Job Access with Sound) is one of the leading screen readers currently on the market. Henter-Joyce, a division of Freedom Scientific , created this application to help people with visual impairments interact with technology. To download a demonstration version of JAWS, visit www.freedomscientific. com. The JAWS demo is fully functional and includes an extensive, highly customized help system. Users can select the voice that reads Web content and the rate at which text is spoken. Users also can create keyboard shortcuts. Although the demo is in English, the full version of JAWS allows the user to choose one of several supported languages. JAWS also includes special key commands for popular programs, such as Microsoft Internet Explorer and Microsoft Word. For example, when browsing in Internet Explorer, JAWS capabilities extend beyond the reading of content on the screen. If JAWS is enabled, pressing Insert + F7 in Internet Explorer opens a Links List dialog, which displays all the links available on a Web page. For more information about JAWS and the other products offered by Henter-Joyce, visit www.freedomscientific.com. Elements Description assign Assigns a valueto a variable, var. clear Clears the contents of the varattribute. clearDigits Clears all digits that the user has entered. goto Navigates to another section of the current CallXML application or to a different CallXML application. The valueattribute specifies the URL of the invoked application. The submitattribute lists the variables that are passed to the invoked application. The method attribute states whether to use the HTTP get or post request type when sending and retrieving information. A get request retrieves data from a Web server without modifying the contents, whereas the post request receives modified data. run Starts a new CallXML session for each call. The valueattribute specifies the CallXML application to retrieve. The submit attribute lists the variables that are passed to the invoked application. The methodattribute states whether to use the HTTP get or post request type. The varattribute stores the identification number of the session. sendEvent Allows multiple sessions to exchange messages. The value attribute stores the message, and the sessionattribute specifies the identification number of the session that receives the message. answer Answers an incoming telephone call. call Calls the URL specified by the valueattribute. The callerID attribute contains the phone number that is displayed on a CallerID device. The maxTimeattribute specifies the length of time to wait for the call to be answered before disconnecting.

Chapter 24 Accessibility 1247 The tag (line 7) encapsulates other CallXML tags. Usually, sets of CallXML tags that perform similar tasks are enclosed within …. The block element in this example encapsulates the , , and tags. A block element also can be nested in other block elements. Lines 20 23 contain some attributes of the tag. The getDigits element obtains the user s touch-tone response and stores it in the variable declared by the var attribute (i.e., ISBN). The maxDigits attribute (line 21) indicates the maximum number of digits that the application can accept. This application accepts only one character. If no maximum is stated, then the application uses the default value, nolimit. The termDigitsattribute (line 22) contains the list of characters that terminate user input. When a user inputs a character from this list, the application is notified that it has received the last acceptable input; any character entered after this point is invalid. These characters do not terminate the call; they simply notify the application to proceed to the next instruction, because the necessary input has been received. In our example, the values for termDigitsare 1, 2, 3 and 4. The default value for termDigits is the null value (”"). The maxTime attribute (line 23) indicates the maximum amount of time that the application will wait for a user response. If the user fails to enter input within the given time frame, then the CallXML application invokes the event handler onMaxSilence. The default value for this attribute is 30 seconds. The onMaxSilence element (lines 27 37) is an event handler that is invoked when attribute maxTime(or maxSilence) expires. The event handler notifies the application of the appropriate action to perform when a user fails to respond. In this case, the application asks the user to enter a value, because the maxTime has expired. After receiving input, getDigits (line 32) stores the entered value in the ISBN variable. The onTermDigit element (lines 39 68) is an event handler that notifies the application of the appropriate action to perform when a user selects one of the termDigits characters. At least one tag must be associated with (i.e., must appear after) the getDigits element, even if the default value (”") is used. We provide four actions that the application can perform in response to the specific termDigits value entered by the user. For example, if the user enters 1, the application reads the ISBN value for the Internet and World Wide Web How to Program: Second Edition textbook. Line 72 contains the event handler, which terminates the telephone call when the user hangs up the telephone. Our event handler is an empty tag (i.e., no action is performed when this tag is invoked). The logging feature (Fig. 24.20) displays the conversation between the application and the user. As in the previous example, the first row specifies the URL of the application and the global variables of the session. The subsequent rows display the conversation : The application asks the caller which ISBN value to read; the caller enters 1(Internet and World Wide Web How to Program: Second Edition), and the application reads the corresponding ISBN. The end of session message states that the application has terminated. We provide brief descriptions of various logic and action CallXML elements in Fig. 24.21. Logic elements assign values to, and clear values from, the session variables; action elements perform specified tasks, such as answering and terminating a telephone call during the current session. A complete list of CallXML elements is available at: www.oasis-open.org/cover/callxmlv2.html
