Hardware architecture

b.no is a dual processor system,

It includes a 32-bit microcontroller that manages :

● Power supply system

● The keyboards

● On/Off power button

● USB port,

As a USB braille display, this processor will ensure the good operation of the device.

For the other uses of b.no, a second more powerful processor features :

● Bluetooth,

● Internal applications (files explorer and note-taker)

● Speech synthesis

In needed cases, the second processor switches on. The power supply from the second

processor will stop working once the device is turned off (press and hold the power button).

The b.no keys

The On/Off power button

The On/Off power button is a key lock that needs to be pulled to be activated.

It allows the device to switch On or Off. A short press leads to “transport” mode. A long press

(> to 2 sec.) leads to “stand by” mode. (See “Start up”)

The control keys

b.no is equipped with 2 sets of 4 buttons (keypad of 4 arrow keys)

Functions of the left keypad :

● Press the up arrow key to open the b.no menu,

● Press the down arrow key to enter or exit the current application menu,

● Press the right arrow key to move forward on the braille display,

● Press the left arrow key to return on the braille display.

Functions of the right keypad :

The 4 buttons are used to simulate the arrow keys. For example, in the menus, the right and

left arrow keys enable the selection of the next or previous element of the menu.

A detailed description of the functions of the control keys can be found in chapter

“APPENDIX - Controller keyboard shortcuts”.

The routing cursor keys

The routing cursor keys have a double-contact function : a light click on any routing cursor

key triggers the first contact, a stronger click will trigger the second contact.

By default, the routing cursor keys functions are the following :

● A light click on the first routing cursor key moves the braille display backward.

● A light click on any routing cursor key moves the braille display forward. When

finished reading, the user does not have to look for any particular button or key,

he/she presses any routing cursor key to move forward to the next display.

● A stronger click is needed to use the routing cursor key as its usual purpose, like

action on an object or positioning the cursor on a text.

The functions assigned to the routing cursor keys can be changed (see APPENDIX

“Functions of the routing cursor key”).

The braille keyboard

The braille keyboard of b.no is composed of 8 keys and 2 thumb keys. Each key is related

to one braille pin.

This is how each key is positioned : '7 3 2 1 4 5 6 8'

The 2 thumb keys are named from left to right : '9' and 'A'.

The braille keyboard must be used by pressing and releasing simultaneously one or several

keys. The functions or characters generated according to the combination of pressed keys

will be detailed later in the document :

● For computer braille, see APPENDIX “8-dot computer braille characters”,

● For the other functions (different from usual characters you may find on a PC

keyboard) see APPENDIX “10 dots braille functions”

● In order to use the braille keyboard in unimanual mode, see APPENDIX “Unimanual

braille keyboard”.

You might have to use some of these modifying functions (Ctrl, Alt, Shift, Windows and

Insert) before typing the keys combination that these functions apply to.

Start Up

The key lock, located on the left side of the device, needs to be pulled in order to start

b.no.

The braille display will switch on and will display the main menu.

Once the device is “on” :

● A short press turns the device into “transport” mode. In this case, all keys stop

working and all dots on the braille display are down.

● A long press (> to 2 sec) turns the device into sleep mode. The second processor

power supply is cut off as well as the braille display. The whole system can remain

this way for several weeks with no need to recharge.

After starting up, b.no will display the main menu:

“usb bluetooth-applications nn%”

Choose “usb” to communicate with a computer through the usb cable. If another internal app

or Bluetooth mode is requested, “bluetooth-applications'' will have to be confirmed which will

start the second processor of the system.

nn% indicates the percentage of the remaining battery power.

In order to return to the main menu ofb.no , press the up arrow key of the left keypad.

Once the second processor starts, the main menu is complete :

“usb <list of documents in editing> <List of connected bluetooth channels> explorer settings

transport turn off”

Use of a menu

A menu appears as a line of labels.

These labels can be made of several words, in this case the braille dot 8 replaces the space

button as a word delimiter.

The first label is the menu title, followed by the character “:”

The followed labels are operable buttons separated with spaces.

The braille dot 7 and 8 blink below the first character of the button, meaning the button is

focused.

A focused button is activated when pressing 9A from the braille display.

As a shortcut, the buttons of the menus can be activated by typing the shortcut letter when

the menu is displayed. The shortcut letter is displayed by the braille dot 8 up and blinking.

When opening a menu, the beginning of the braille display shows the focused object.

There are 2 methods to navigate throughout a menu :

1. You can either move forward or move backward the braille display on the menu (light

click on the routing cursor key, or right and left arrow of the left keypad), then activate

one of the buttons of the menu with a stronger click on the routing cursor key located

above this button.

2. You can move the marking on the different buttons of the menu (left/right arrow of the

right keypad). The focused button is located at the beginning of the braille display,

therefore you can activate this button (9A of the braille keyboard).

Use of a dialogue box

A dialogue box shows a list of objects with different values associated, some of these values

can be editable.

A dialogue box is like a menu and can be used the same way. There is a “OK” button to

confirm and close it and a “Cancel” button to cancel the modifications. This “Cancel” button

is displayed only when modifications are possible in the dialogue boxes.

Besides the buttons, you may find in a dialogue box :

● text object

● editable object

● liste object

“Editable” objects and “list” objects have a name and values associated. They are displayed

as “name-value” forms.

“Text” objects have only an informative purpose, any action has no effect. They have no

value and will display as “name” form.

Editable objects will enable the modification of a value. Any keyboard action on an editable

box will display a blinking braille dots 7-8 under each character to mark selected text. Any
