Using Braille Displays > This chapter provides information about using refreshable braille > displays, both plug in and Bluetooth, with VoiceOver. This chapter also > includes a list of the many types of braille displays VoiceOver > supports. > About refreshable braille displays > If you connect or pair a supported braille display to your computer, > VoiceOver automatically detects it and sends it information about what > is displayed on the screen. You can connect multiple braille displays to > your computer and each display will mirror the same content at the same > time, which can be useful in a classroom setting. > > By default, VoiceOver displays uncontracted braille, which you can also > display using eight-dot braille. You can also use contracted braille; if > you do, VoiceOver dynamically changes the display under the cursor from > contracted to uncontracted braille, so that you can read and edit more > easily, and then changes back to contracted braille when you move the > cursor. > > A braille display typically contains more than just the contents of the > VoiceOver cursor. It describes the contents of the entire line on which > the VoiceOver cursor is focused, including items to the left and right > of the VoiceOver cursor. For example, when the VoiceOver cursor is > focused on an item in a window, the braille device displays items like > icons, checkboxes, and pop-up menus, as well as text that is to the left > and right of the item in the VoiceOver cursor. This collection of > items-the VoiceOver cursor and the items to its left and right on the > same horizontal line-make up a "line" of braille. > > When you interact with an item in the VoiceOver cursor to get more > detail about it, the braille description changes to provide more detail > as well. For example, if you move the VoiceOver cursor onto a toolbar, > VoiceOver describes only the toolbar on the braille display, because > toolbars stretch the entire width of a window. When you interact with > the toolbar, the braille display describes each item in the toolbar from > left to right. > > VoiceOver raises dots 7 and 8 to indicate the position of the VoiceOver > cursor, to help you locate it within the line of braille. (You can turn > off this feature in VoiceOver Utility.) Similarly, when you're editing > or selecting text, the text selection is represented by dots 7 and 8. > VoiceOver also indicates the position of the text selection cursor, > called the "I-beam," by flashing dot 8 of the braille cell preceding the > text selection cursor and dot 7 of the braille cell trailing the text > selection cursor. > > VoiceOver provides additional information about what's on the screen > using three status cells. Each status cell provides a designated type of > information. You can set the number of status cells that are used and > their location on the braille display. For example, you can choose to > use the cell that shows text status and set its location to be on the > left of your display. > > VoiceOver detects the type of braille display you're using and sets > default preferences appropriate for that display. Use VoiceOver Utility > to assign VoiceOver commands to keys on your braille display. You can > use the braille display while listening to VoiceOver speak, or you can > mute the speech. If your braille display has a Perkins-style keyboard, > you can type on it. > Pair a Bluetooth braille display > Before you can use a supported Bluetooth braille display with VoiceOver, > you must pair your braille display with your computer. You can pair only > one Bluetooth braille display at a time. You pair the display only once; > it remains paired until you remove it from the list of displays. After > your braille display is paired, VoiceOver detects it whenever it's > turned on and within range; if it's your primary braille display, you > can then use it. > When VoiceOver is on, open VoiceOver Utility by pressing VO-F8. > Click the Braille category, click Displays, and then click Add (+). > Select your Bluetooth braille display in the list. > VoiceOver lists only the Bluetooth braille displays that are within > range of your computer and that appear to match a VoiceOver braille > display driver. > > Click Select. > You may be asked to provide a pairing passcode (such as 0000 or 1234, > two common default codes). Check the documentation that came with your > braille display for the passcode. > If the Bluetooth braille display you selected in the list doesn't work > with VoiceOver, it's likely that its driver doesn't match a VoiceOver > driver. Try pairing a different Bluetooth braille display. > > If your Bluetooth braille display isn't listed, make sure you have set > the display to be discoverable. For more information, check the > documentation that came with your braille display. > About panning on a braille display > Sometimes a line of braille is too wide to fit on the braille display. > You can move through, or "pan," the line by pressing the left and right > buttons on the display. Each left or right pan moves according to the > number of cells (including status cells) your display contains. > > When you move the VoiceOver cursor using the VoiceOver keys, the braille > display automatically pans when necessary to follow it, even wrapping to > the previous or next line. > Use router keys on a braille display > Many braille displays have router keys above the braille cells that you > can use to move the cursor. Generally, you press the router key above a > particular item in the line of braille to move the VoiceOver cursor or > selection to that item. > > Pressing a router key over a control moves the VoiceOver cursor to that > control if the VoiceOver cursor is not already there. If the VoiceOver > cursor is already on that control, pressing the router key performs the > control's default action. For example, to click a button, you could > press the router key to move the VoiceOver cursor to the button and then > press the router key again to click the button. You would not have to > touch the computer's keyboard at all. Similarly, when you're reading or > navigating text and you press a router key, the VoiceOver cursor moves > to that location in text. > > You can also press the router key above a status cell to display an > expanded braille description of each dot in the cell. To exit the > description, press any other router key. > Show status information on a braille display > The cells of a braille display show the content of the line on the > screen where the VoiceOver cursor is focused. If your braille display > has dedicated status cells, VoiceOver can use them to show additional > information about the line, such as the text attributes. > > If your braille display doesn't have status cells, VoiceOver uses the > first one to three cells on the left to show status (or you can have > VoiceOver use the cells on the right). VoiceOver reserves another cell, > which it leaves blank, as a separator between the status cells and the > other cells. > When VoiceOver is on, open VoiceOver Utility by pressing VO-F8. > Click Braille in the category table, and then click Layout. > Select one or more of the checkboxes next to Status Cells. > If you don't select any of the following checkboxes, status is not > shown, and all of the reading cells are used to show the content of the > current line. > > Show general display status: Show information about the direction in > which to pan the current line, and about announcements. For example, > dots 1 and 2 indicate unread and read announcements, and dots 7 and 8 > indicate you can pan the display left or right. > > Show text style: Show common text styles, such as bold or italic font. > For example, dots 1 and 2 indicate bold and italic text respectively, > and dot 4 indicates the selected text is misspelled. > > Show extended text style: Show less common text styles, such as > strikethrough or superscript. For example, dots 1 and 2 indicate text is > superscript or subscript respectively, and dot 5 indicates the selected > text has a double underline. > Press the router key above a status cell to display an expanded braille > description of each dot in the cell. To exit the description, press any > other router key. > Review announcements on a braille display > VoiceOver sends announcements to the braille display about events that > aren't represented visually on the screen. For example, if an > application in the background needs attention or if a new window appears > onscreen, VoiceOver sends an announcement to the braille display. > VoiceOver stores up to 30 announcements in the history, with the most > recent one listed first. > > If you chose to show general display status on your braille display, you > can review announcements. > > Show status information on a braille display > On the status cell that shows general display status, dot 1 indicates > whether there are new unread announcements. Dot 2 indicates whether the > current announcement has already been read. > If you assigned the Announcement History command to a braille display > key, press that key to show the most recent announcement in the reading > cells. > To cycle through the announcement history, press the Up Arrow key to > move backward to the oldest announcement, and press the Down Arrow key > to move forward to the most recent announcement. > When you're done reviewing announcements, press any router key above the > announcement to redisplay the current line. > Assign VoiceOver commands to braille display keys > VoiceOver detects whether your braille display provides input keys and > assigns common VoiceOver commands to the keys. In this way, you can work > more efficiently by using the computer keyboard less. For example, > VoiceOver might assign the Down command to the D3 key; when you press > that key on your braille display, the VoiceOver cursor moves down one > line on the screen. You can change the default assignments and add your > own. > With your braille display connected to or paired with your computer and > with VoiceOver on, open VoiceOver Utility by pressing VO-F8. > Click Braille in the category table, click Displays, select the braille > display you want to assign commands for, and then click Assign Commands. > > Assign a VoiceOver command to braille display keys. > To change the command assigned to keys listed in the table, navigate to > the keys, and then choose a command from the pop-up menu. > To add new braille keys to the table so you can assign a command to > them, click Add (+) to add a row, press Command-B, and then within five > seconds press the braille keys you want to add. A sound effect counts > down the seconds. Then choose the command you want to assign to the keys > from the pop-up menu. > To remove braille keys you added, click Remove (-). > Mirror a braille display > You can connect multiple USB braille displays to your computer and have > all of them display the same braille output at the same time. The > braille displays can be of different types and models; they don't need > to be the same. > Connect or pair with your computer the braille display you want to use > to control all other braille displays that are connected to your > computer. This display is called the "primary braille display." > In the Displays pane of the Braille category in VoiceOver Utility, > select the braille display and then select the "Primary braille display" > checkbox in the display information section. > To prevent input from other braille displays that are connected to your > computer, choose "Primary braille display" from the "Allow input from" > pop-up menu. > > Connect additional braille displays to your computer. These displays > will mirror the output from the primary braille display. > Supported braille displays > Mac OS X supports a wide range of USB and Bluetooth braille displays. > > Note:Bluetooth only, or USB and Bluetooth, displays are indicated in the > table.
