This NVDA add-on allows braille to be entered via the PC keyboard. Currently, the following keyboard layouts are supported:

  • English QWERTY keyboard.
  • French (France).
  • German (Germany).
  • Italian (Italy).
  • Persian.
  • Portuguese (Portugal).
  • Spanish (Spain and Mexico).
  • Turkish.

How to configure

The add-on can be configured from its category in the NVDA's settings dialog, under NVDA's menu, Preferences submenu. A gesture for opening the add-on settings panel can be assigned from Input gestures dialog, configuration category.

Check the corresponding checkbox if you want to type using only one hand, or ensure it's not checked if you prefer to type using the standard mode (two hands).

使用方法

  1. Press NVDA+0 to enable braille input. This gesture can be changed from Input gestures dialog, Braille category.
  2. Type braille by pressing keys together on the PC keyboard as if it were a braille keyboard.

    • If you want to enter text using two hands, use the following keys if you work with a QWERTY English keyboard, or the keys located at the corresponding positions in other layouts:

      • f, d and s for dots 1, 2 and 3 respectively.
      • j, k and l for dots 4, 5 and 6 respectively.
      • Use the keys a and ; (semi-colon) for dots 7 and 8, respectively.
      • You can also use the keys on the row above; i.e. q, w, e, r, u, i, o and
    • If you want to type text using one hand, you can compose characters pressing keys simultaneously or in several keystrokes, adding the dots corresponding to the desired character. Press g or h to type the character when you have added all its dots. If you make a mistake building a character, you can clear the dots before typing it by pressing t or y. The keys used in QWERTY English keyboard are the following:

      • Left hand: f, d, s, r, e, w, a, q for dots 1, 2, 3, 4, 5, 6, 7 and 8.
      • Right hand: j, k, l, u, i, o, ; (semicolon), p for dots 1, 2, 3, 4, 5, 6, 7 and 8.
  3. You can press most other keys as normal, including space, backspace, enter and function keys. Take care about not pressing alt+shift, since changing the keyboard layout may affect the entered dots.

  4. Press NVDA+0 to disable braille input.

重要な注意点

This add-on uses NVDA's in-built braille input support. Therefore, the input table used is that specified in NVDA's Braille Settings dialog.

キーボードによっては、特にラップトップキーボードでは、押されるキーの組み合わせを扱えない場合があります。この場合、キーの一部は単に無視されることになります。残念ながら、WindowsにもNVDAにもキーが受け取られないため、これを修正する方法はありません。上の行のキーを片手または両手で使用すると、使用しているキーボードがこれらのキーの組み合わせを許可している場合は、入力出来るかもしれません。
