## Introduktion till tillgänglighet

This chapter introduces you to accessibility in the GNOME Desktop.

### Översikt för tillgänglighet

All software products should incorporate accessibility features to enable people with disabilities to use the software easily and efficiently. Recent legislation such as Section 508 of the U.S. Rehabilitation Act heightens awareness of the need to provide accessible software.

The GNOME Desktop is easy to use and incorporates many accessibility features. Every supported application and utility in the GNOME Desktop is designed with accessibility and usability in mind. Users with physical disabilities such as low vision or impaired motor skills can use all of the functionality of the GNOME Desktop thanks to the customization tools that are available. The customization tools enable you to customize the appearance and behavior of the desktop.

The ability to easily customize the GNOME Desktop contributes greatly to the accessibility of the desktop. This guide describes the various customization options that you can use to tailor the desktop to suit your particular needs.

## Konfigurera musen och tangentbordet

This chapter describes how to configure the mouse and keyboard to make these devices accessible to more users.

### Konfigurera musen

Use the Mouse preference tool to configure the mouse to suit your needs. To open the Mouse preference tool, choose System Preferences Mouse. The Mouse Preferences dialog is displayed.

#### Konfigurera musens beteende

The following sections describe how to modify the behavior of the mouse to suit your needs.

##### To Configure the Mouse for Left-Handed Use

To configure the mouse for left-handed use, click on the Buttons tab in the Mouse Preferences dialog, then select the Left-handed mouse option. When you select this option, the system swaps the functions of the left mouse button and the right mouse button immediately.

##### To Configure the Double-Click Behavior

If you have difficulty double-clicking, you can increase the period of time that the system allows to elapse between the first click and the second click of a double-click. For example, if the double-click timeout setting is 0.4 seconds, you must perform the second click of a double-click within 0.4 seconds of the first click. If the second click occurs more than 0.4 seconds after the first click, the system interprets the two clicks as two single clicks.

To configure the double-click timeout setting, perform the following steps:

1. Click on the Buttons tab in the Mouse Preferences dialog.

2. Use the Timeout slider to specify the timeout in seconds that the system allows between the two clicks of a double-click. Moving the slider to the right will increase the timeout interval in 0.1 second intervals. In the same manner, moving the slider to the left will decrease the timeout in 0.1 second intervals.

3. Double-click on the light bulb to the right of the slider to test the setting. If you perform the two clicks of the double-click within the timeout specified, the light bulb lights up fully to display a yellow glow around the bulb. If you do not double-click within the timeout specified, the light bulb does not light fully. You should increase the timeout setting and try again. When the light bulb lights, the timeout setting is suitable for your needs.

##### To Change the Size of the Mouse Pointer

To change the size of the mouse pointer that is displayed on the desktop, perform the following steps:

1. Click on the Pointers tab in the Mouse Preferences dialog.

2. This will display a list of pointer themes and sizes available.

3. By default, GNOME does not include mouse pointer themes. Information about installing and using pointer themes can be found in the User Guide.

On some platforms you must log out and log in again for this setting to take effect.

##### To Locate the Mouse Pointer

If you have difficulty locating the mouse pointer on the screen, you can enable an option to highlight the pointer when you press the Control key. To enable this option, click on the Pointers tab in the Mouse Preferences dialog, then select the Highlight the pointer when you press Ctrl option. When you press Control, the system displays an animation around the pointer to highlight the pointer.

On some platforms, you must log out and log in again before this setting takes effect.

##### To Configure the Speed and Sensitivity of the Mouse

To configure the speed and sensitivity of the mouse, perform the following steps:

1. Click on the Motion tab in the Mouse Preferences dialog.

2. Configure the following options:

   Acceleration

     Use the slider to specify the speed at which the mouse pointer moves around the screen when you move your mouse.

     If you select a low setting, the mouse pointer moves at a speed similar to the speed at which you are physically moving the mouse. This means that you need to physically move the mouse larger distances to cover the screen area. If you select a high setting, the mouse pointer moves at a faster speed than the speed at which you physically move the mouse. This means that you need to physically move the mouse small distances to cover the screen area.

   Känslighet

     Use the slider to specify how responsive the mouse pointer is to movements of your mouse. Moving the slider to the right will increase the sensitivity and moving it to the left will decrease the sensitivity.

   Tröskelvärde

     Use the slider to specify the distance that you must move an item before the system interprets the move action as a drag-and-drop action.

#### Konfigurera muspekaren

The following section describes how to modify the display characteristics of the cursor.

##### To Stop the Cursor Blinking

To stop the cursor blinking in text boxes and fields, perform the following steps:

1. Choose System Preferences Keyboard to start the Keyboard preference tool.

2. In the Keyboard tabbed section, deselect the Cursor blinks in text boxes and fields option.

#### To Use the Keyboard to Emulate the Mouse

If you have difficulty using a mouse, you can use the keyboard to emulate the mouse functions. See of this guide for more information.

### Konfigurera tangentbordet

Use the Keyboard preference tool, to configure the keyboard accessibility options. To open the Keyboard preference tool, choose System Preferences Keyboard. Accessibility options can be enabled by selecting Accessibility. This will open a new dialog, Keyboard Accessibility Preferences, also known as AccessX.

Before you can use the Keyboard Accessibility preference tool on Solaris systems, you must follow the steps outlined in of this guide.

The Keyboard Accessibility Preferences (AccessX) dialog enables you to customize your keyboard in the following ways:

- To use the numeric keypad to emulate mouse actions. See .

- To specify the duration for which you must press-and-hold a key before the system accepts the keypress. See .

- To ignore rapid, repeated keypresses of the same key. See .

- To accept key combinations in sequence rather than simultaneously. See .

- To emit an audible notification when a user activates or deactivates a toggle key. See .

- To ignore long keypresses of the same key and control the repeat rate of a keypress. See .

#### To Activate the Keyboard Accessibility Options

To activate the keyboard accessibility options, perform the following steps:

1. Choose System Preferences Keyboard and select Accessibility

2. Select the Enable keyboard accessibility features option.

3. Click on the Basic tab.

4. Select the Beep when features turned on or off from keyboard option to receive an audible notification each time a user enables or disables a keyboard accessibility option using the following keyboard shortcuts:

5. To automatically disable the keyboard accessibility options if the options are not used for a specified number of seconds, select the Disable if unused for X seconds option. Use the slider to specify the number of seconds of keyboard idle time required before the system disables the keyboard accessibility options.

   This option is intended for computers that are shared by a number of different users, some of whom require the keyboard accessibility options.

6. Changes made will be instantly applied.

#### Aktivera tangentbordet för att emulera musen

The mouse keys feature enables you to use the numeric keypad on the keyboard to emulate mouse actions. This feature benefits users who have difficulty using a mouse or other pointing device. To enable and configure the mouse keys feature, perform the following steps:

1. In the Keyboard Accessibility Preferences (AccessX) dialog, select the Mouse Keys tab.

2. Select the Enable Mouse Keys option.

3. Configure the following options to determine the behavior of the mouse pointer when you control the pointer from the numeric keypad:

   Maximum pointer speed

     Use this spin box to specify the maximum speed, in pixels per second, at which the pointer moves around the screen.

   Time to accelerate to maximum speed

     Use this spin box to specify the duration, in milliseconds, before the pointer accelerates to the maximum pointer speed.

   Delay between keypress and pointer movement

     Use this spin box to specify the interval, in milliseconds, between a keypress and the time when the pointer starts to move.

When you enable mouse keys, the keys on the numeric keypad have the following functions:

##### Numeric Keypad to Mouse Function Mapping

Numeric Keypad Keys | Funktion

   To select or deselect the slow keys feature from the keyboard, press-and-hold Shift for eight seconds. This will present a dialog confirming that you with slow keys enabled. The Shift keyboard shortcut automatically selects all of the slow keys options. If you selected the Beep when features turned on or off from the keyboard option in the Basic tab, after four seconds the system beeps three times to indicate that the system is about to select or deselect the feature.

3. Use the Only accept keys held for slider or spin box to specify the duration, in milliseconds, for which you must press-and-hold a key before the system accepts the keypress. Use the Type to test settings text box to test the slow keys setting and modify the setting as required.

4. To enable audible indications of keyboard input and acceptance, select the following options:

   Beep when key is pressed

     Select this option to hear a beep when you press a key.

   Beep when key is accepted

     Select this option to hear a beep when the system accepts a keypress.

   Beep when key is rejected

     Select this option to hear a beep when the system rejects a keypress. The system rejects a keypress if you do not press-and-hold the key for the duration that is specified in the Only accept keys held for spin box.

#### To Enable the Bounce Keys Feature

The bounce keys feature enables you to customize the keyboard to ignore rapid, repeated keypresses of the same key. For example, users with impaired motor skills might press the same key several times when they intend to press the key once. This feature enables you to customize the keyboard to ignore repeated keypresses.

To enable and configure the bounce keys feature, perform the following steps:

1. From the Keyboard Accessibility Preferences (AccessX) dialog select the Filters tab.

2. Select the Enable Bounce Keys option.

3. Use the Ignore duplicate keypresses within slider or spin box to specify the duration in milliseconds (ms) after the first keypress for which the system ignores repeated keypresses of the same key. For example, if you select a duration of 500 ms, the system ignores all repeated keypresses of the same key that occur within 500 ms of the first keypress.

4. Select the Beep if key is rejected option to hear an audible indication when the system ignores a key.

If you want to enable the bounce keys feature, ensure that the Enable Slow Keys option is deselected. The slow keys feature requires you to press a key for a specified duration before the system accepts the keypress as a valid keypress. If you cannot press the key for the duration that is specified by the slow keys setting, deselect the Enable Slow Keys option to enable the system to accept your input.

#### To Enable the Sticky Keys Feature

The sticky keys feature enables you to press the keys in a key combination in sequence rather than simultaneously. This feature is designed for users who are unable to press two or more keys simultaneously.

To enable and configure the sticky keys feature, perform the following steps:

#### Introduktion till teman

A theme is a group of coordinated settings that specifies how a desktop component or a group of desktop components appears. You can use themes to modify and control the appearance of the desktop in a consistent manner. When you apply a theme, the system modifies many desktop components simultaneously to achieve the desired effect. For example, if you apply a theme that increases the font size across the desktop, the theme also modifies the size of panels and icons on the desktop for optimum compatibility with the font size.

A theme contains settings that affect different parts of the desktop as follows:

Controls

  The controls setting for a theme determines the visual appearance of all windows, applications, panels, and panel applications. The controls setting also determines the visual appearance of the GNOME-compliant interface items that appear on windows, applications, panels, and panel applications, such as menus, icons, and buttons. Some of the controls options that are available in the desktop are designed for special accessibility needs.

Window border

  The window frame setting determines the appearance of the border around windows only.

Ikon

  The icon setting determines the appearance of icons on panels and on the desktop background.

## Använd hjälpmedelstekniker

The GNOME Desktop contains the following applications to enable users with a physical disability to use the desktop:

- Skärmtangentbord

- Skärmläsare och förstorare

Before you can use the On-Screen Keyboard and Screen Reader and Magnifier on Solaris systems, you must follow the steps outlined in of this guide.

### Skärmtangentbord

The On-Screen Keyboard application displays virtual keyboards on your desktop. You can use the standard mouse pointer or alternative pointing device to operate the virtual keyboards. On-Screen Keyboard displays the following types of keyboards:

- Compose keyboards that enable you to compose text. To type alphanumeric characters, you select the characters on the compose keyboard.

- Dynamic keyboards that On-Screen Keyboard generates to reflect the applications that are currently running on the desktop. For example, On-Screen Keyboard generates keyboards that contain keys to represent the applications that are running on your desktop or the menus that are contained in an application.

To start On-Screen Keyboard, choose Applications Accessibility On-Screen Keyboard. For more information about the On-Screen Keyboard application, see the Help for On-Screen Keyboard.

#### Maximizing Application Windows for On-Screen Keyboard Users

If you are an On-Screen Keyboard user, you cannot use any application in Full Screen mode because the application window obscures the On-Screen Keyboard display.

To resize the window for use with the On-Screen Keyboard application, perform the following steps:

1. Do not enable the Full Screen mode in the application.

2. Give focus to the application window.

3. Press F10 to maximize the application.

### Skärmläsare och förstorare

The Screen Reader and Magnifier application enables users with limited vision, or no vision, to use the GNOME Desktop and associated applications. Screen Reader and Magnifier provides the following functionality:

- Skärmläsare

  The screen reader enables non-visual access to standard applications in the GNOME Desktop, using speech and Braille output.

- Förstorare

  The magnifier provides automated focus tracking and fullscreen magnification to aid low-vision users.

To start Screen Reader and Magnifier, choose Applications Accessibility Screen Reader and Magnifier. For more information about the application, see the online Help for Screen Reader and Magnifier.

Before you use On-Screen Keyboard or Screen Reader and Magnifier, you must disable the screensaver. To disable the screensaver, perform the following steps:

1. Choose System Preferences Screensaver.

2. Deselect the Activate screensaver when session is idle checkbox.

## Systemadministration

This appendix describes some tasks that a system administrator needs to perform to enable accessible login and to facilitate the use of the assistive technologies that are available in the GNOME Desktop.

### Configuring the Desktop for Accessible Login

The GNOME Desktop includes an Accessible Login feature. The Accessible Login feature enables users to:

- Log in to the desktop even if the user cannot easily use the screen, mouse, or keyboard in the usual way.

- Launch assistive technologies at login time by associating a user action with an assistive technology application. The user can perform the user action from the standard keyboard, or from a keyboard, pointing device, or switch device that is attached to the USB or PS/2 mouse port. These user actions are called gestures.

- Change the visual appearance of the login dialog before the user logs in, for example, to use a high contrast theme for better visibility.

#### To Enable Accessible Login

To enable the Accessible Login feature for the GNOME Desktop, you must configure the desktop to use the GNOME Display Manager (GDM) as the login manager. GDM is the default login manager on Linux systems but not on Solaris systems, therefore the instructions to enable Accessible Login differ depending on the platform you are using.

##### To Enable and Configure GDM on Solaris Systems

To enable and configure GDM as the login manager on Solaris systems, perform the following steps:

1. Log in as the `root` user.

2. Öppna filen `/etc/X11/gdm/gdm.conf`.

3. Search the file for the following line:

   `#AddGtkModules=false`

   and replace the line with the following:

   `AddGtkModules=true`

   This step enables the GtkModules.

4. Search the file for the following line:

   `#GtkModulesList=gail:atk-bridge:dwellmouselistener:keymouselistener`

   and delete the `#` from the start of the line so that the line reads:

   `GtkModulesList=gail:atk-bridge:dwellmouselistener:keymouselistener`

   The above lines must be displayed as single lines in the `gdm.conf` file without line breaks. The formatting of this guide may display the lines over two lines.

   This step loads all of the GtkModules to enable assistive technologies such as On-Screen Keyboard and Screen Reader and Magnifier. You can edit the line above further to load only the GtkModules that you require to support the user base. For example:

   - If you need to use the Screen Reader and Magnifier, include `gail` and `atk-bridge`.

   - If you need to use a pointing device without buttons or switches, include `gail`, `atk-bridge`, and`dwellmouselistener`.

   - If you use pointing devices with switches, alternative physical keyboards, or switch and button devices, include `keymouselistener`.

   - On-Screen Keyboard can operate without `gail` and `atk-bridge` but with a reduced feature set.

   For optimum accessibility, include `gail` and `atk-bridge`.

5. Save the `/etc/X11/gdm/gdm.conf` file.

6. Enter the following command to stop the dtlogin manager:

   `/usr/dt/bin/dtconfig -d`

7. Enter the following commands to configure GDM as the login manager:

   `svccfg import /var/svc/manifest/application/gdm2-login.xml`

   `svcadm enable application/gdm2-login`

   If you make any changes to the `/etc/X11/gdm/gdm.conf` file after you enable GDM, you can execute the following command to restart GDM and activate the changes:

   `gdm-restart`

8. Edit the file `/etc/passwd` to append the following to the end of the `gdm` line:

   `:/etc/X11/gdm/home`

9. Create the `/etc/X11/gdm/home` directory and assign ownership of the directory to the `gdm` user.

10. Starta om ditt system.

##### To Configure GDM on Linux Systems

To configure GDM on Linux systems, perform the following steps:

1. Log in as the `root` user.

2. Öppna filen `/etc/X11/gdm/gdm.conf`.

3. Search the file for the following line:

   `#AddGtkModules=false`

   and replace the line with the following:

   `AddGtkModules=true`

   This step enables the GtkModules.

4. Search the file for the following line:

   `#GtkModulesList=gail:atk-bridge:dwellmouselistener:keymouselistener`

   and delete the `#` from the start of the line so that the line reads:

   `GtkModulesList=gail:atk-bridge:dwellmouselistener:keymouselistener`

   The above lines must be displayed as single lines in the `gdm.conf` file without line breaks. The formatting of this guide may display the lines over two lines.

   This step loads all of the GtkModules to enable assistive technologies such as On-Screen Keyboard and Screen Reader and Magnifier. You can edit the line above further to load only the GtkModules that you require to support the user base. For example:

   - If you need to use the Screen Reader and Magnifier, include `gail` and `atk-bridge`.

   - If you need to use a pointing device without buttons or switches, include `gail`, `atk-bridge`, and `dwellmouselistener`.

   - If you use pointing devices with switches, alternative physical keyboards, or switch and button devices, include `keymouselistener`.

   - On-Screen Keyboard can operate without `gail` and `atk-bridge` but with a reduced feature set.

   For optimum accessibility, include `gail` and `atk-bridge`.

5. Save the `/etc/X11/gdm/gdm.conf` file.

   If you make any changes to the `/etc/X11/gdm/gdm.conf` file after you enable GDM, you can execute the following command to restart GDM and activate the changes:

   `gdm-restart`

6. Edit the file `/etc/group` and append the following to the `audio` line:

   `,gdm`

   This step ensures that speech works with GDM.

7. Starta om ditt system.

#### Starta hjälpmedelstekniker vid inloggning

If you load the `keymouselistener` and `dwellmouselistener` GtkModules in the GDM configuration file, you can assign user actions to launch specific assistive technologies at login time. These user actions are called gestures. The gesture associations are contained in the following GDM configuration files:

- `/etc/X11/gdm/modules/AccessKeyMouseEvents`

- `/etc/X11/gdm/modules/AccessDwellMouseEvents`

If you modify these files, you must restart your system before the changes take effect.

The following sections contain examples of the gestures that you can add to the GDM configuration files.

The gestures must be contained in a single line in the `AccessKeyMouseEvents` file without line breaks. The formatting of this guide might display the examples in the following sections over two lines.

##### To Start Screen Reader Using a Keyboard Shortcut

Edit the `AccessKeyMouseEvents` file to associate keyboard shortcuts with assistive technologies. For example, the following line enables you to press-and-hold CtrlS for one second to start Screen Reader and Magnifier in speech and Braille mode:

Solaris:

`<Control>s 1 1000 10000 /usr/sfw/bin/srcore --login --disable-magnifier --enable-speech --enable-braille`

Linux:

`<Control>s 1 1000 10000 srcore --login --disable-magnifier --enable-speech --enable-braille`

##### To Start Magnifier Using a Keyboard Shortcut

Edit the `AccessKeyMouseEvents` file to associate keyboard shortcuts with assistive technologies. For example, the following line enables you to press-and-hold CtrlM for one second to start Screen Reader and Magnifier in magnifier mode:

Solaris:

`<Control>m 1 1000 10000 /usr/sfw/bin/srcore --login --enable-magnifier --disable-speech`

Linux:

`<Control>m 1 1000 10000 srcore --login --enable-magnifier --disable-speech`

##### To Start On-Screen Keyboard Using a Switch or Button Gesture

Edit the `AccessKeyMouseEvents` file to associate switch, key, or button gestures with assistive technologies. Since the primary input device for many On-Screen Keyboard users is a switch or button, this is a good way to enable users to start On-Screen Keyboard at login time.

If there is a tendency for a user to start an application unintentionally, you can associate the gestures with multiple switch presses or minimum durations. For example, the following line starts On-Screen Keyboard in inverse scanning mode when the user presses the switch that is defined as Switch 2 three times within two seconds, for a minimum of 100 milliseconds for each press:

Solaris:

`<Switch2>3 100 2000 /usr/sfw/bin/gok --login --accessmethod=inversescanning --scan-action=switch1 --select-action=switch2`

Linux:

`<Switch2>3 100 2000 gok --login --accessmethod=inversescanning --scan-action=switch1 --select-action=switch2`

Users who use single switches may prefer to start On-Screen Keyboard in automatic scanning mode. The following line starts On-Screen Keyboard in automatic scanning mode when the user presses the switch on an alternative access device for more than four seconds:

Solaris:

`<Switch>1 4000 5000 /usr/sfw/bin/gok --login --accessmethod=automaticscanning --scan-action=switch1 --select-action=switch1`

Linux:

`<Switch>1 4000 5000 gok --login --accessmethod=automaticscanning --scan-action=switch1 --select-action=switch1`

For information about the On-Screen Keyboard operating modes, see the online Help for On-Screen Keyboard.

##### To Start On-Screen Keyboard Using a Motion-only Gesture

You can define gestures that involve only the motion of a pointing device such as a mouse, or an alternative pointing device, such as a head pointer or trackball. The syntax of the gesture does not change depending on whether you are using a mouse or an alternative pointing device. Edit the `AccessKeyMouseEvents` file to associate motion gestures with assistive technologies.

If the `dwellmouselistener` GtkModule is loaded, alternative pointing devices are temporarily latched to the core pointer. This means that if the user moves the alternative pointing device, the onscreen pointer moves.

For example, the following line starts On-Screen Keyboard in dwell mode when the user moves the onscreen pointer from inside the login dialog through the top edge, back into the dialog through the top edge, out of the dialog through the left edge, back into the dialog through the left edge, and similarly through the bottom and right edges of the dialog in a cross pattern:

Solaris:

`TTLLBBRR O 10000 /usr/sfw/bin/gok --login --access-method=dwellselection --input-device=MOUSE[3]`

Linux:

`TTLLBBRR O 10000 gok --login --access-method=dwellselection --input-device=MOUSE[3]`

Note that the `--input-device` parameter specified in the gesture must match the name of the extended user input device, such as a head pointer or trackball, as specified in `/etc/X11/XF86Config`.

#### Additional Requirements for Accessible Login

To enable the Accessible Login feature to use alternative pointing devices and switch devices such as sip-and-puff switches, wheelchair-mounted switches, or trackballs, you might need to modify your X server system configuration to recognize these devices. You can use most devices that emulate mouse buttons with the Accessible Login feature and On-Screen Keyboard, including USB single switches and mouse-like pointing devices.

You should not configure an alternative input device to control the primary onscreen pointer. This might result in undesirable behavior or cause situations from which the user of the alternate input device cannot recover without using the primary keyboard or mouse. To prevent this problem, please remove any occurrences of the attributes `SendCore` or `AlwaysCore` from any of `InputDevice` lines in the X Server configuration file.
