-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA512 hi all My name is kendell clark, and I just switched over to fedora a couple of weeks ago. I keep meaning to show up at the documentation meetings but I keep sleeping through them. I've been working on the abandoned accessibility guide, and I've basically completed it. The problem is, I've only modified the plain text version, not the docbook xml markup. I'll attach it so that others can look at it. Would anyone here be willing to help convert that into the docbook that the fedora documentation expects? I'm trying to learn the language so I can eventually do this myself but I'm not there yet.

Abstract This document describes some of the hardware devices, applications, and utilities available to assist people with disabilities to use a computer with the Fedora operating system. ------------------------------------------------------------------------ 1. Introduction --------------- There are approximately 500 million people worldwide with some kind of visual, hearing, or mobility impairment. People with disabilities often find it extremely difficult to effectively use existing and emerging technologies which are often designed without regard to their needs. Websites with inaccessible content can also be problematic for screen readers and other specialized devices used by the disabled community. Accessible features have been voluntarily integrated into operating systems, web interfaces, and other technologies because of marketing potential or because it has been "the right thing to do." Equal access to educational, professional, and recreational technologies is rapidly becoming a legal requirement. Federal agencies in numerous countries are formulating accessibility standards. Specialized hardware devices, applications, and utilities are available which considerably increase the usability of Linux for individuals with special needs. Screen readers and magnifiers, on-screen keyboards, mouse tools, and other tools are available for Fedora users to help make their computer usable. 2. Why should people choose Fedora as an accessibility solution? ---------------------------------------------------------------- Linux offers an inexpensive and efficient solution for the disabled community. Open source software costs far less compared to tools that run on other operating systems and Linux tools are often freely downloadable. While the Graphical User Interface (GUI) is convenient for sighted users, it is often inhibiting to those with visual impairments because of the difficulty speech synthesizers have interpreting graphics. Linux is a great operating system for users with visual limitations because the GUI is an option, not a requirement. Most modern tools including email, news, web browsers, calendars, calculators, and much more can run on Linux without the GUI. The working environment can also be customized to meet the hardware or software needs of the user. Fedora is an extremely popular Linux distribution. Most industry professionals are familiar with Fedora, making it relatively straightforward to find assistance if necessary. The Fedora Project issues regular and frequent updates and enhancements, and computers that have Fedora installed can download and install these automatically and without cost. It is therefore easy and economical to keep computers secure and up to date. 2.1. The Section 508 Mandate In the United States, the Section 508 Mandate is an addendum to the Rehabilitation Act made in 1998 that requires federal agencies to use accessible electronic and information technologies so that people with special needs have the same opportunities as everyone else. For detailed information about the requirements of the Section 508 Mandate, visit http://www.section508.gov/ 2.2. The Voluntary Product Accessibility Template (VPAT) The VPAT template details how a particular product or service conforms to Section 508 criteria. The VPAT helps federal personnel adhere to Section 508 by helping them determine whether they are buying the most accessible IT products and services available. The VPAT template participation by private vendors is voluntary. These templates are hosted on the individual vendor websites. The vendors maintain their own information and the government does not endorse this information in any way. 3. Available open source tools, utilities and drivers ----------------------------------------------------- Current development is focusing on visual and mobility impairments. There are both software and hardware based solutions available. There are also both console and graphical solutions available. 3.1. Hardware The biggest advantage of the hardware speech solutions is that speech is available before the operating system loads, which even makes it possible for people with a visual impairment to install the operating system. Hardware solutions include speech synthesizers, braille terminals, braille printers, sip and puff systems, and eye gaze pointing devices. These devices are usually very expensive and it is difficult to find drivers for them. Drivers are being written (mostly for speech synthesizers) for Linux but they need to be tested and integrated by the community into "upstream" software projects before becoming part of Fedora. 3.2. Software This document focuses mostly on software tools and utilities that work with Linux. Most of these tools have been developed by the Open Source community and many have not yet been tested by the Fedora Project. 4. Screen Readers ----------------- Screen readers are important accessibility tools that allow a person with limited vision to have the computer read what is on the screen. There are numerous solutions that provide this service. This section covers some of the ones available to Fedora users. 4.1. Orca for GNOME GNOME supplies its own screen reader, Orca. This package is installed by default on all Fedora systems. Additional information on Orca may be found by visiting http://live.gnome.org/Orca/. Enabling orca To enable orca, if you are on the workstation image of fedora, press alt+windows+s. You will shortly hear “Screen Reader on.” Orca will start from then on until it is disabled with alt+windows+s. Should you accidentally or purposely press alt+windows+s after orca has been enabled, you will hear “screen reader off.” Orca will no longer start up automatically and must be enabled again. It can also be run manually by pressing alt+f2 to open up the run dialog and typing orca. Should orca ever crash or become unresponsive, it can be restarted either by toggling orca off then on again, or by opening up the run dialog and typing “orca –replace”. If You are using the mate spin of fedora, press alt+windows+s. You will shortly hear “Screen Reader on.” You will then need to go into system>preferences>assistive technologies and check the box labeled “enable assistive technologies.” Be sure to press the “preferred applications” button and make sure orca is set to launch at startup. No further action is required. You can set various settings of orca such as the speech synthesizer, rate, pitch, voice, volume, punctuation level, verbosity, etc by accessing orca's preferences. This can be done from anywhere while orca is running by pressing the “orca” key plus the space bar. If you are using the desktop layout (the default) this is either the insert key on your keyboard, which is normally to the left of the home key, or the numbpad insert key, which is at the bottom of the number pad, and looks like the shift key. If you are using the laptop keyboard layout, the “orca” key is the caps lock key, which is just above shift on most keyboards. You can change the keyboard layout by accessing orca's preferences and tabbing to the keyboard layout combo box on the general tab, which is the default tab opened when the preferences are opened. If you need more help on orca, press the “help” button in orca's preferences to access the orca manual in yelp, the gnome help application. 4.1.1. Karet navigation. For many gnome applications that display web content, such as the gnome web browser, the evince document reader and the gnome help application, you cannot read contents with orca until the system karet is enabled. This is a blinking cursor that follows your progress as you scroll through the text with the arrow keys. To enable karet navigation, press the f7 key. You will be asked if you wish to enable karet navigation, followed by a “do not ask me again” option which makes the selection permanent. This must only be done once. After this, orca can be used to read the contents of those applications. This is not required in most other applications. However, if orca is ever unable to read the contents of an application which contains text content, such as a web browser or text editor, try pressing f7 to see if it might be turned off. 4.2. Jovie for KDE Jovie is the KDE system for Text-to-Speech, previously known as ktts. Jovie consists of a Text-to-Speech Daemon, a Konqueror plugin, and an extension for the Kate text editor. The Daemon provides text-to-speech functionality to applications, such as KMouth and KNotify, via D-Bus. It also provides an icon from the system tray, for additional features. From this tray icon, Jovie can speak the contents of a text file, speak the contents of the clipboard, and access the control module for configuration. Comprehensive information on jovie can be found on the KDE website: HTTP://docs.kde.org/stable/en/kdeaccessibility/jovie/index.html To start Jovie in Fedora, run jovie from the command line. To start it from the KDE graphical menus, select Applications > Utilities > Text-to-Speech. 4.3. Using Emacspeak with Fedora Emacspeak is a speech interface that allows visually impaired users to interact independently and efficiently with the computer. Emacspeak has dramatically changed how hundreds of blind and visually impaired users around the world interact with the personal computer and the Internet. A rich suite of task-oriented speech-enabled tools provides efficient speech-enabled access to the evolving semantic world wide web. When combined with Linux running on low-cost PC hardware, Emacspeak provides a reliable, stable speech-friendly solution that opens up the Internet to visually impaired users around the world. Emacspeak is not installed on fedora by default. To install it, open a terminal and type sudo dnf install emacspeak. Answer y when you are asked if you wish to continue. Once this is complete you can launch emacspeak by typing “emacspeak” in a terminal. If all is working properly, you should hear emacspeak start up, and report “welcome to emacspeak. I am completely operational, and all my circuits are functioning perfectly!” Before using Emacspeak, you should familiarize yourself with some documentation. Start with A Gentle Introduction to Emacspeak by Gary Lawrence Murphy, which is available online at http://tldp.org/LDP/espk-ug/html/index.html The Emacspeak HOWTO written by Jim Van Zandt is also a very good resource, although the document is limited to the Slackware distribution. The Emacspeak HOWTO is available online at: http://slackware.osuosl.org/slackware-3.3/docs/Emacspeak-HOWTO The following sections describe how to perform various tasks using Emacspeak and Fedora. The Meta key At various points, the following sections refer to the Meta key. This key is fundamental to Emacs (and therefore Emacspeak) commands, but is very seldom found on modern keyboards. Most keyboard layouts map the Alt key to take the place of Meta. 4.3.1. Reading news using Fedora and Emacspeak Gnus is the news reader included with Emacspeak. Gnus gets the appropriate data from the .newsrc file in the user's home directory. To post and read news through Emacspeak, refer to http://www.gnus.org/ for manuals, tutorials, HOWTOs, and more. To start Gnus, press Meta+X, then type gnus and press Enter. This command displays all the newsgroups you are subscribed to. To select a newsgroup, highlight your selection and press the space bar. Next, specify how many articles you would like to open: type a number and press Enter. This splits the screen into two buffers. The top section is the summary buffer, the bottom section is the article buffer. You should now be able to read your news. 4.3.2. Sending and reading email using Fedora and Emacspeak There are several email clients available in Emacspeak. The Gnus utility can actually be used for both email and news. Press Meta+X to start Gnus, then press M to use the mail client. The easiest tool to use is RMAIL. To send a message using RMAIL, press Ctrl+X, then type rmail. When you are in RMAIL, press M. Fill in the To: and Subject: fields. Put the body of the message below the line that reads -text follows this line-. To send the message when you are finished, press Ctrl+C twice in succession. To read a message using RMAIL, press Meta+X, then type rmail and press Enter. For more information on using RMAIL visit http://www.gnu.org/software/emacs/manual/html_node/emacs/Rmail.html 4.3.3. Using Emacspeak to execute Linux shell commands It is not necessary to leave Emacspeak to execute a Linux command. To execute a command within Emacspeak, press Esc, then type ! followed by the name of the command when Emacspeak prompts you. To exit the command output window, press Ctrl+X, followed by 1 This functionality is extremely useful. You can even print and compile files you are working on within Emacspeak. For more information on Linux shell commands refer to Josh's Linux Guide or any other comparable command resource. Josh's Linux Guide is available from http://linuxguide.sourceforge.net/linux-commands.html 5. Screen Magnifiers -------------------- Screen magnifiers are just what they sound like, programs that considerably magnify portions of the computer screen so it can be more easily read. 5.1. KMagnifier In KDE, KMagnifier, or KMag, magnifies the area around the cursor or a user-defined area. You can also save a magnified portion of the screen to disk. Additional information can be found at http://kmag.sourceforge.net/ 5.1.1. Installing KMagnifier In Fedora, KMagnifier is packaged in the kdeaccessibility package. This package also contains kmousetool, kmouth, and ktts, all of which are discussed in other areas of this guide. To install kdeaccessibility you can either select System > Administration > Add/Remove Software and then type in kdeaccessibility in the screen that pops up or in a terminal window type su -c "yum install kdeaccessibility". 5.2. Magnification in gnome shell. There is a magnifier built into the gnome shell. It can be activated in the following ways. While in gnome shell, press control+alt+tab until you hear top bar. Release the keys. You will land on the “activities” button. Press tab until you get to the “accessibility” menu. Press The down arrow to expand and enter into this menu. Press the down arrow until you get to “zoom” and press enter. This activates the magnifier. You can change preferences of the magnifier and gnome's other built in accessibility tools by accessing the “universal access” settings. To do this, press the windows key to open up the activities overview and start typing universal access. Highlight the “universal access” icon and press enter. Highlight the tool who's preferences you want to change and press enter. You can also turn various tools on and off from this dialog. 6. Mouse Tools -------------- Mouse tools allow the mouse to be used in different ways, and provide an alternate solution to people with limited mobility. 6.1. KMouseTool A program for KDE, KMouseTool, provides an alternate method for clicking the mouse by clicking the mouse whenever the cursor pauses and even provides a dragging capability. KMouseTool works with any mouse or pointing device. 6.1.1. Installing KMouseTool In Fedora, KMouseTool is packaged in the kdeaccessibility package. This package also contains kmagnifier, kmouth, and ktts, all of which are discussed in other areas of this guide. To install kdeaccessibility you can either select System > Administration > Add/Remove Software and then type in kdeaccessibility in the screen that pops up, or in a terminal window type su -c "yum install kdeaccessibility". 6.2. Mousetweaks Similar to KDE's KMouseTool, GNOME's Mousetweaks provides functions for simulated secondary clicks, dwell clicks, and pointer capture. Additional information on Mousetweaks can be found at http://library.gnome.org/users/mousetweaks/ 6.2.1. Using mousetweaks. Mousetweaks is installed by default in the fedora workstation image. To activate the mouse tools, open the top bar by pressing and holding control+alt+tab, and pressing the tab key until you hear “top bar”. Release the keys. Press tab until you land on the “accessibility” menu. Press the down arrow to expand and enter this menu. Press the down arrow key until you land on “mouse keys” Press enter to activate. From now on, you can operate your mouse by the numbpad on your keyboard. Keys 4 and 6 move the mouse left and right, 2 and 8 move up and down, and 5 clicks. You can change various options by accessing the “universal access” dialog in gnome's settings and pressing enter on the “mouse keys” option. 7. On_Screen_Keyboards ---------------------- Many on screen keyboards have been created for environments with no keyboards such as wearable computers or palm devices. They are also very useful for accessibility enhancement when used with a mouse or no-hand tools such as a head-mouse or an eye-tracker. Some of these tools included in Fedora are described in this section. 7.1. Indic Onscreen Keyboard iok is Indic Onscreen Keyboard. It provides virtual keyboard functionality. It currently works with Inscript and xkb keymaps for Indian languages. The following keymaps are currently available: Assamese, Bengali, Gujarati, Hindi, Kannada, Marathi, Malayalam, Punjabi, Oriya, Tamil, Telugu. iok can even try to parse and display non-inscript keymaps. Visit http://sourceforge.net/projects/iok/ for more information on iok. 7.1.1. Installing iok To install iok in fedora, you can either open up the gnome software application by pressing the windows key to open up the activities overview and typing “software”. Press enter on the software icon. In the search box, type iok. On the results screen, press enter on the “install” button, making sure you're installing iok. After a few minutes, you will get a notification that iok has been installed. Alternatively, you can open up a terminal and type “sudo dnf install iok”, answering y when you are asked if you wish to proceed. 7.2. Florence Florence is an extensible, scalable, virtual keyboard, whose sole requirement is a pointing device. Once enabled, Florence displays an icon in the notification area on the GNOME Panel. Florence can be sent to the background when it is not needed, making it a practical solution for screens of all sizes. To toggle whether Florence is displayed or hidden, just click the icon. Alternatively, Florence can be set to autohide until an editable area is selected. Florence can also be configured easily to be transparent, through the Preferences dialogue. To edit all available Preferences, right-click on the icon on the GNOME Panel, and choose Preferences from the dropdown list. Additional information on Florence Virtual Keyboard can be found at the project's homepage, http://florence.sourceforge.net. Once Florence is installed, to view full documentation right-click on the icon on the GNOME Panel, and choose Help from the dropdown menu. 7.2.1. Installing Florence Florence is available in the fedora package repositories; to install either open up the gnome software application and then type “florence” in the search box that appears, or type “sudo dnf install florence” in a terminal window. 7.3. Dasher Dasher is an information-efficient text-entry interface, driven by natural continuous pointing gestures. Dasher is not really a "keyboard" but instead uses a zooming interface and a predictive language model with word completion. Dasher makes data entry easy by people utilizing a joystick, touchscreen, trackball, or mouse for one-handed operations. It can also be utilized by people using no-hand tools such as a head-mouse or an eye-tracker. Additional information on Dasher can be found at http://library.gnome.org/users/dasher/. 7.3.1. Installing Dasher In Fedora, Dasher can be easily installed by either opening up the gnome software application and typing “dasher” in the search box that appears, or in a terminal window type “sudo dnf install dasher”. 7.3.2. Gnome on screen keyboard. Gnome shell includes it's own on screen keyboard built in. To activate it, press and hold control+alt+tab, pressing tab repeatedly until you hear “top bar”. Press tab until you land on the “accessibility” menu, and press down arrow. Press down arrow until you land on “on screen keyboard” and press enter to turn it on. 8. Help for Linux Desktops -------------------------- Certain desktops have their own internal settings that can help with accessibility. 8.1. KDE In KDE, keyboard and mouse settings can be configured in kcontrol. These settings are available by selecting Personalization > Accessibility. Additional information on Accessibility Tools in KDE can be found at http://accessibility.kde.org/ 8.2. GNOME The GNOME 3 Universal Access menu In GNOME, accessibility controls can be configured in the Universal Access menu. By selecting Activities and then typing Universal Access a menu will display that allows tweaking of all accessibility options within the GNOME 3 desktop environment. Additional information on GNOME's accessibility tools can be found at http://library.gnome.org/users/gnome-access-guide/ 8.3. XFCE In XFCE, accessibility options for the keyboard and mouse can be configured in the Accessibility Settings dialogue. To access these settings from the graphical menus, select Preferences > Accessibility. Alternative keyboard configurations, such as keyboard shortcuts, can be set by selecting Preferences > Keyboard. Similarly, extra mouse related settings are available by selecting Preferences > Mouse. Some minor additional accessibility options for XFCE can be found through Preferences > Window Manager Tweaks. 8.4. Sugar: Making computing accessible for children. The Sugar Learning Platform is an innovative learning interface for children, which encourages learning, critical thinking, and creativity. Sugar was originally created for the OLPC (One Laptop Per Child) initiative. The traditional "office-desktop" style computer interface can be quite intimidating and is often not very accessible for children who are learning to read and write. Sugar offers an alternative, more child-friendly approach to learning and computing. To install the Sugar platform in fedora, you can either open up the gnome software application and type “sugar” in the search box that appears; or alternatively type “sudo dnf install sugar” in a terminal. There is also an alternate version of Fedora featuring the Sugar Platform, known as Sugar on a Stick It is available at http://spins.fedoraproject.org/soas/ Various Sugar Activities are also available through the Fedora package repositories. To browse the available sugar activities through the GNOME package manager, open up the gnome software application, and then type “sugar-” in the search box that appears; you will be presented with a list of packages relating to Sugar. Alternatively, type “sudo dnf install sugar-” in a terminal window. More information on Sugar for learners, parents, teachers, and contributors can be found at the official website, http://sugarlabs.org/ A.
