Hardware architecture b.note 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.note, a second more powerful processor features : * Bluetooth, * Internal applications (files explorer, note-taker, media player) * 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.note 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.note is equipped with 2 sets of 4 buttons (keypad of 4 keys) Functions of the left keypad : * Press the up key to open the b.note menu, * Press the down key to enter or exit the current application menu, * Press the right key to move forward on the braille display, * Press the left key to move backward 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.note is composed of 8 keys and 2 thumb keys. Each key is related to one braille dot. 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 keys (alt, ctrl…) see APPENDIX “10 dots braille functions” * In order to use the braille keyboard in unimanual mode, see APPENDIX “Unimanual braille keyboard”. Start Up The sliding button, located on the left side of the device, needs to be pulled in order to start b.note. 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 3 sec) turns the device into sleep mode. The second processor power supply is cut off as well as the braille display. After starting up, b.note will display the main menu: “usb-a usb-b bluetooth-applications nn%” Choose “usb-a” or “usb-b” to communicate with a computer through the usb cable on one of the 2 serial port emulations. 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.note , press the up key of the left keypad. Once the second processor starts, the main menu is complete : “usb-a usb-b 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 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 key 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 key 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. Just as for the menus, the blinking dots 7 and 8 show the focused element, the raised dot 8 indicates the shortcut letter that will be activated by typing Alt+letter (on the braille keyboard 8A + braille combinaison of the letter). 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 character typed on the braille display will replace this value. An action on the editable box will shut editing mode. The list objects will permit the selection of a value in a defined list, the list will have to be focused and the values, with up/down keys from the right keypad, scrolled. The main menu of b.note Two menu versions exist according to the second processor whether it is On or Off. This chapter describes the first version of the main menu, then the Applications menu in the second version. USB-A and USB-B These two buttons permit the use of b.note as a braille display connected via USB serial port. In this mode, any keyboard action on the keys is sent to the connected device, and the braille display will be refreshed when needed. Bluetooth-applications This button will enable you to enter the different applications of b.note, which will start the second processor. 20 seconds later, the main menu becomes the Applications menu. nn% This last element indicates the battery power. The Applications menu of b.note This menu replaces the main menu when the second processor has started. To shorten the application menu, the settings application allows you to place most of these applications in the main menu, in a submenu called 'More Apps,' or even make them invisible. USB same purpose as the previous menu. Bluetooth (0 to 4) The number of the buttons will depend on the number of Bluetooth connections, the text related to these buttons is the name of the Bluetooth system that b.note is connected to. These buttons will allow the connection of the keyboard and the braille display b.note to the Bluetooth system (PC, tablet or smartphone). If no Bluetooth connection is activated, there is no button of this kind in the menu. Document (0 to 5) These buttons go back to an open document, the text’s name of these buttons is the same as the file name. When the button start with ‘*-’ it means the document is open in read only mode. If no document is being edited, there will not be any button in the menu. Explorer This button allows the user to launch the file explorer application (See chapter Applications>File explorer). Settings This button allows the user to launch the settings ’application (See chapter Applications>Settings). Transport Same use as the short press on the On/Off switch of the device (See chapter Start Up). Turn Off Same use as the long press on the On/Off switch of the device (See chapter Start Up). The applications Introduction The applications of b.note are made of a file explorer, an editor, a settings page. An Audio application will allow the creation of a playlist to launch audio files. A Radio application will allow the selection of a radio station and listen to it. A minesweeper game and a mastermind game can be activated on the “games” parameter from the preferences section. By default, these 2 applications are not visible. The file explorer The files explorer presents a list of files and directories included in the current directory. This current directory is “My documents” from b.note, it can change according to the user’s operation. Above the base folder 'my documents', a root folder with the elements of the 'go to' menu function is presented. This is an alternative method to this function to go to one of its elements (trash, usb key, etc.). You may use the backspace key to move to the parent directory. In order to index the different documents, the files explorer has features that will enable it to create/erase subfolders and make copies or operate “directory to directory” transfer. The files can be exchanged by bluetooth with a PC or smartphone or with an USB stick plugged on the USB port. The files explorer can zip and extract archives in zip format. The explorer has its own menu, see details below. Introduction and moves in the current directory The directories and files from the current directory are indexed by alphabetical order. Each element of this directory relates to a braille line, use the up or down key of the right keypad to navigate throughout this list. Action on a directory opens it, and it becomes the current directory. Action on a file opens it in the editor if the format is known (“.txt”, “.mbe”, “.docx”, “xlsx”, “.odt”, “.pdf”, “.brf”, “.rtf”, “.epub”). When the editor opens a file in a format other than “.txt” it converts the file to .txt format and then deletes the converted file. However, the original file can be found in the recycle bin (trash). Note : The musicxml and the bxml files can be read, played and edited on b.note. You will find another manual that explains how this works. If you move back the display (left key of the left keypad) it will allow you to see the name of the current directory. A strong click on the routing cursor key located above this name moves to the parent directory. Braille key 9 (backspace) can also be used. Each element of the directory starts with letters “f” or “d” marking its type (file or directory). A “test.txt” file will be displayed as “f test.txt” and a history directory as “d history”. after the filename the size is displayed “(x mo)”, “(x ko)”, “(x octets)”. In this list, characters can be typed,b.note will go on the file or directory that begins with this string, so you might quickly move throughout the list. Once the string is found, it is possible to move to the next one with F3. Multiple selection The file explorer enables the selection of files and directories to cut and copy. When an element is part of a selection, it will be prefixed with characters “s”. By default, the current element is selected. A file test.txt will be displayed as “sf test.txt”. When an element is not in the selection, it will be prefixed with characters “n”. A file test.txt will be displayed as “nf test.txt”. In order to select, press F8 (braille 1259) ; to close a selection, press Esc (braille 1245A). When the selection is activated, you can switch from one element to another and press Space (braille A) to select/deselect the file/directory displayed. To select the whole contents of the current directory, you can press the shortcut CTRL+a. Trash When you delete files or directories, they are sent to the trash. You can see the contents of the trash (via menu Directory>trash) and restore a file mistakenly sent to the trash. You can permanently delete files or directories from the trash. Note : The user has to manage the trash properly, as the trash keeps being filled when deleting documents, the user will have to empty it from time to time. File explorer menu The explorer menu is displayed when pressing the down arrow key from the left keypad. The contents of the explorer menu is listed below. Pressing the same keys return to the directory of the files explorer. The “applications” button of this menu permits the user to exit the explorer and return to the Applications menu.

The audio output switches on the headset when a headset is connected. USB * usb-a-hid and usb-b-hid keyboard: shows how the braille combinations are sent, when working on one of the 2 usb port series, as a USB keyboard or to the screenreader directly. These settings can be modified independently but the screenreader should support them, so the changes made might not last. (See APPENDIX - USB Braille keyboard) * simulation esys : yes/no When set to yes b.note is showing itself as an esys so it can communicate with old applications. Bluetooth * Power : yes/no When set to no the bluetooth is turned off. the bnote has more battery life. * Name: The Bluetooth adapter is named by default “Esys-bnote-nnnn” where “nnnn” is the serial number of the device. Though you can customize the last part of this name. In order to make this name change effective, b.note will have to be restarted. * Visibility : You can make the Bluetooth adapter visible and allow it to be detected for pairing. This parameter will remain in the defined state, it would be better to make it invisible to avoid any unpleasant pairings. * List of paired devices : This line lists the paired devices, which leads to a dialogue box in order to erase any pairing. * simulation esys : yes/no When set to yes b.note is showing itself as an esys so it can communicate with old applications. * Automation: This section is only visible when devices are paired.Each paired device is presented on a line that will show the b.note’s reaction if there is a connection, do nothing or move automatically to the Bluetooth mode. Wifi * Power : yes/no When set to no the WIFI is turned off. the bnote has more battery life. * Connected to : Gives the SSID, the IP address, and the percentage of quality of the connected wifi spot. * Favorites : lists the saved ssid access points, any action will define a ssid/password of a new access point. In this dialogue box, a scan button will show the closest access points. * Country : This parameter allows you to modify the region parameter of the wifi module, this parameter must only be modified when changing country. User interface * Message language: This parameter enables language choice of all b.note messages. * Braille language: This parameter enables the selection of the braille table used. * Braille type : This line indicates the type of braille used to display menus, dialog boxes, the list of folders/files in explorer and settings.It is possible to set this parameter to braille dots-8, grade1 or grade2. * Spaces in label : When this parameter is set to no, spaces in labels and editable areas of menus and dialog boxes are displayed in braille with dot 8 raised. * Visible shortcuts : this setting authorizes the visualization of the shortcuts next to each element of the menu. * developer mode : Set to yes, you can download the versions currently under development (beta) and have access in the main menu to a skeleton application which allows you to understand the use of menus and dialog boxes. * import/export settings : only available in the menu. Allows you to save and restore the settings Main Menu In this section we find a parameter per application allowing you to choose how its display in the main menu, 3 choices: * Display in the main menu * Displayed in the “more apps” submenu from the main menu * Invisible. By default only explorer and settings are in the main menu, all the other apps are invisible. explorer * Empty Bluetooth Folder: This setting, when set to 'yes,' automatically erases the Bluetooth folder upon the device's shutdown. This folder is where files transferred via Bluetooth are stored. * Empty Trash at Shutdown: This setting allows to automatically emptying the trash at the device's shutdown. * Number of Recent Files: This setting allows you to set the size of the recent files list in explorer’s file menu. Editor * Braille type: This line indicates the type of braille used to display documents in the editor. It is possible to set this parameter to braille dots-8, grade1 or grade2. * Line length: This line indicates a dialogue box to adjust the maximum number of characters in an editor’s line. The text sections are cut in several lines where the words are indivisible. By default, this parameter equals the number of cells from the braille display (20 or 40) so no broken word can be found on the display. * Forward display : Two types of movements on the display are available, the “normal” mode where each editor’s line is presented and the “significant” mode where the empty lines disappear. * Autoscroll display: This setting allows you to define the number of seconds between each automatic advancement of the Braille display. * Cursor visible : This parameter enables to hide the braille line of the cursor in the text (braille dots 7 and 8 blinking) * Dots 7-8 visible: This parameter enables to hide dots 7 and 8 from the editor’s braille displays. Math * format : 2 display format are available, standard or scientific (exponent 10 display) * précision : Define the numbers of decimal. * fraction : Allow to display by fraction when possible. * angle : this parameter sets the angle unit of the calculator with degree or radian.

Auto the vocal will say the new word, ask you have to hard click on the word to be said by the synthesis, no no vocal * keeping spacing : no or yes. set to yes it will remove the accidentally spaces typed at the beginning or the end of the word. * Allow the wrong hit : set to yes it will allow you to type a character not included in the word. Set to no you may type any character. Keyboard * Mode : This parameter enables the user to move the braille keyboard into one of the unimanual modes (see APPENDIX - Unimanual braille keyboard). * Braille 78 : This parameter conditions actions when braille keyboard dot 7 or 8 are typed alone. If it is set to "character" the character of the chosen braille table is generated. If it is set to function, pressing b7 performs the Correction function (backspace) and it on b8 makes Enter. Once setup to function the 9 and A key are both doing space. * Inverted : This parameter enables switching the left keypad’s functions and the right keypad’s functions. * Light, strong, adjacent, double light, double strong press : These settings permit adjustments of the routing cursor keys operation (see APPENDIX - Routing cursor keys functions). Standby * Transport time out : This parameter defines the period (min.) during no activity that will lead to switching the device in transport mode. The 0 value invalidates this mechanism. * Time out for shutdown : This parameter defines the period (min.) during no activity will lead to shutdown the device. The 0 value invalidates this mechanism.

Currently, it includes two applications: "Word Games" and "Calculation Games." They are accessible from the main menu of the B.note. Word Games The goal of this game is to reproduce the written word. The display is divided into two parts: * The left part with the written word, * The right part where the user's input will be displayed. The record menu: * See for this level: Displays the score for the selected level, * Clear for this level: Resets the score for the level to 0. Other options: * Go to the next word: Allows you to move on to another word proposal, * Change language: Allows you to switch word suggestions from French to English and vice versa, * Change level: Allows you to change the level with more or fewer letters, * Reset the application: Restores the application to its original state. Levels When you first open the application, you will be prompted to choose a level. The levels are divided as follows: * The top 4 dots: 1245, * The 6 dots: 123456 (no capital letters), * The 8 dots, * Note: The last level is saved when the device is turned off. Calculation Games The goal of this game is to write the result of a calculation. You need to solve operations that can be additions or multiplications. The game is presented as follows: * The operation followed by the equal sign, * A blinking cursor to enter the result. The record menu: * See for this table: Displays the score obtained for the selected table, * Clear for this table: Clears the score for the selected table. Other options: * Change table: Allows you to choose another operation table, * Reset the application: Restores the game to its original state. Tables When you first open the application, you need to choose a table. Each table is indicated by a number and the sign of its operation. For example, the multiplication table of 3 will be indicated as "3*" and the addition table of 3 as "3+". Note: The last table is saved when the device is turned off. Allow vocal: * Auto: Announces the proposal each time and can be repeated by pressing one of the cursors above the example word, * Ask: Announces the word only when pressing one of the cursors above the example word, * Never: Does not announce the word; * Keep spaces: Removes accidental spaces at the beginning or end of a word, * Allow mistyping: Allows or disallows the user to enter a character that is not correct. Note: For the last option, if the user chooses to disable it, they will not be able to move the cursor. At the end of their input, the message will be displayed automatically. If the user leaves this option active, they can move their cursor normally. They will need to press the enter key once the word is typed for the check to be done. The Timer This application has both a stopwatch and a timer. During its use, the display indicates the elapsed time and the state (stopped, started, paused). To start or stop the stopwatch, simply press the enter key or one of the cursors above the status message. When the stopwatch is activated, the displayed values are hours, minutes, and seconds. You can get the time in hundredths of a second by pausing the stopwatch or by pressing one of the cursors above the elapsed time. To clear the elapsed time, simply press the backspace key. Marker Menu * Add a marker: Captures the time at the moment of the action and prompts you to enter a name, * View markers: Displays a dialog box allowing marker management. Launch a Timer To launch a timer, press the option of the same name in the menu bar. Specify the number of hours, minutes, and seconds, then press ok. Once the time has elapsed, you will be automatically redirected to the application, even if you are elsewhere in the B.note. Marker Management When you open the marker management box, the list of different captured times is displayed. To find out what name was given to a marker, navigate to it and press "view name." You can rename and delete a marker. When you are done, press "close" or escape. The games b.note includes 2 games that can be visible or not, depending on the “visible games” parameter from the preferences section. Minesweeper Rules of the game The objective of the game is to clear a grill containing hidden bombs without detonating any of them, with help from clues about the number of neighboring mines in each field. The aim of the game is to uncover the empty fields in a minimum of time. Display and movements The grid is displayed on the braille display as : Line number, grid positions, elapsed time The position values are as follows : ‘*’ : non-discovered position, ‘ ‘ or a number : Position discovered ‘b’ : position where a bomb has been set The movements of the cursor, indicated by braille dots 7 and 8 in the grid, are carried out with the right keypad, and the characters can be typed on the braille keyboard as follows : ‘ ‘ : order of the discovery of the position ‘b’ : présence of a bomb in this field Mastermind Rules of the game The objective of the game is to propose a sequence of numbers. The system will respond by indicating the number of existing digits and the number of digits correctly placed in the sequence that needed to be guessed. The main goal is to find the sequence in a minimum of proposals. Display and movements Each proposal is displayed on a line with the result. You read the different proposals with the top and low keys from the right keypad. The “Enter” key (b9A) will allow the user to make a new proposal. Diary The diary application was developed by Théotime Berthod (acres.louer.0l@icloud.com), using b.note developers mode. We would like to thank him for his participation. You’ll find all the information to develop your own application in the developers manual. This app allows you to note events or homeworks when at schools in an integrated calendar. Basic operation At first opening it will display no event. This message remains until an event is added. If one or more events are set they’ll be displayed as follows. Use up and down arrows to choose the event and enter or routing cursor to validate. * date * state * subject (title) * content (description) App browsing Several display modes are available and listed below. Press the Braille 9 key (backspace) to list them, then up and down key from the right keypad to choose and enter to validate. * show from today : Display all events from the b.note date. * show for today : Display the event for the b.note’s date. * Show Not Done : Display only the not done state event from the b.note’s date * Show all agenda : Display all the event * Show calendar : switch to calendar mode Calendar mode Once switched to the calendar view the current day is displayed with the name of the day, the number, the month and the year. Today is shown before the day to indicate you. ex *today friday 10 february 2023 2 events If the day contain event a “*” is displayed before the name of the day and the number of event is shown after the year. Up and down arrow will move one day before or next, the left and right arrow will move from one week before or next. To display all the events of the selected day validate with enter or routing cursor. To come back to the calendar view use backspace. The event menu New (CTRL+n): Open a dialog box to create an event. If you are The day is selected just type the wanted day then use the routing cursor to select the month then the year. Then select the subject and type, then the content if you want to add more text. Choose create to validate you event or cancel to delete it modify (enter): Open a dialog box with the same element as the create one to modify the event. A checkbox done yes or no is added. Change status (CTRL+t): change the status of the event done or not done. Delete (del): Display a warning box if you validate the event is deleted Delete expired events (CTRL+del): After validation delete all the prior to today’s date events Goto menu Previous week (b235a) : go to first event of previous week Next week (b256a) : go to first event of next week Previous day (left arrow) : go to first event of previous day Next day (right arrow) : go to first event of next day The goto menu is not available in calendar view Find menu Find a date (ctrl + d) : type the day, the month and the year to go. Find in agenda (ctrl + f) Find a word or a sentence in the subject or the content. a checkbox is available to choose the done or not done event. DIARY MANAGER Import diary (CTRL+i): Open a dialog box to choose the .csv file to import. ATTENTION: the .csv file must respect the following features. • the separators must be ";" • The first line must contain the four element “date ", “subject ", “content ", " todo ", • An empty line should be present at the end of the file • The date format must be “ dd/mm/yyyy” • The “todo” column must contain only 0 or 1 (0 « not done» and 1 « done »). Export diary (CTRL+e): Open a dialog box to create a .csv file. The default csv file name is my agenda with the date. You may choose your own name then choose export button. Cancel button will get out the box without action. Empty diary: This function erases all the agenda content. About: Open a dialog box with the release information. Diary settings The settings are available in settings apps in the main menu Display agenda: Yes or no the diary is visible or no in the main menu. Default presentation (standard, today, not done, calendar): Choose which view will be displayed at start. At start up report events not done for the same day : yes or no, display a warning at b.note start for not done event for the same day. At start up report events not done for the next day : yes or no, display a dialog box at b.note start for events not done for the next day. ________________ b.note with a screenreader b.note can communicate with another system via a USB connector or Bluetooth. Its use is not different from any other use of a standard refreshable braille display. For more information, please go to the screenreader documentation and driver for b.note. b.note has some distinctive features detailed below. USB b.note can be used as an HID keyboard and work independently of the screenreader. Therefore b.note will be able to show any braille combinations or transfer these combinations to the screenreader that will display the matching characters and functions. It will produce 2 entry modes (See APPENDIX - USB Braille keyboard). Screenreaders Jaws and NVDA work with these features. For NVDA : On the left keypad, press the down and right keys simultaneously, or press the down and left keys simultaneously, to go from one input method to another. * The first mode enables a braille display to perform all keyboard shortcuts with Ctrl+key or Alt+key. * The second mode enables the use of grade 2 with NVDA. Note : a checkbox in NVDA braille settings permits to change this method. For Jaws : The operating mode is in the driver’s file "Program File/Freedom Scientific/Jaws2020/Driver/Braille/esysiris/eurobraille.ini" the name of the parameter is UseHidKeyboard=0 ou 1. Bluetooth Bluetooth can be used to connect b.note to a screenreader and transfer files between b.note and a Windows computer or any Android system (See APPENDIX “Pairing Bluetooth” and “Bluetooth files transfer”). ________________ APPENDIX - Editor - Search The search for a string of characters in the editor can be done by scrolling down the document (F3), or scrolling up the document (Shift + F3). Several parameters can refine the search : * Ignore character case: If Yes, an alphabetical character is identified whatever the character case is (upper/lowercase) * Hide accents : If Yes, a character is identified whatever the accentuation is, therefore é, è ê, ë and e become the same character. * Entire word : If yes, only the complete words are identified in the search string. APPENDIX - Editor - Math. Description b.note editor allows calculating math paragraphs. One Paragraph must include only one math expression; you must not mix text and math expressions. The calculating functions are available in the math menu in the editor. You may write the math expressions in a computer Braille language or in BEU (Braille English Unified) described below. Your paragraph should start by dot Braille 6 then dot Braille 2 to be recognized as math in computer braille or by dot Braille 56 then dot Braille 56 as math in BEU. If you use several paragraphs each of them will start with a braille mathematical sequence (b6, b2 or b56,b56). Math UEB language (Unified English Braille) Generalities Spaces are not significant. Only lowercase characters are allowed. The result of the calculation is stored in the “r” variable. so you may chained the calculations using this variable. For statistical functions you can define values enumeration. Numbers They are preceded by a braille number indicator (⠼) character = braille value 0 = b245 1 = b1 2 = b12 3 = b14 4 = b145 5 = b15 6 = b124 7 = b1245 8 = b125 9 = b24 decimal indicator = b256 space = b5 Constants Pi = b45 + b1234 e = b15 + b4 Blocs Fraction = 12356 … b23456 Parenthesis = b5 + b126 … b5 + b345 Bracket = b46 + b126 … b46 + b345 Brace = b456 + b126 … b456 + b345 Squareroot = b146 … b346 Root n = b146 b35 n … b346 Operators Equal = b5 + b2356 Addition = b5 + b235 Subtraction = b5 + b36 Division = b5 + b34 ou b34 si derrière un nombre Modulus = b456, b1256 Multiplication = b5 + b236 ou b6 + b35 exponent = b35 One argument functions Logarithme népérien = b123 + b1345 Logarithme base 10 = b123 + b135 + b1245 Sine = b234 + b24 + b1345 Cosine = b14 + b135 + b234 Tangent = b2345 + b1 + b1345 Cotangent = b14 + b135 + b2345 Arc sine = b1 + b1235 + b14 + b234 + b24 + b1345 Arc cosine = b1 + b1235 + b14 + b14 + b135 + b234 Arc tangent = b1 + b1235 + b14 + b2345 + b1 + b1345 Arc cotangent = b1 + b1235 + b14 + b14 + b135 + b2345 Hyperbolic sine = b234 + b24 + b1345 + b125 Hyperbolic cosine = b14 + b135 + b234 + b125 Hyperbolic tangent = b2345 + b1 + b1345 + b125 Hyperbolic cotangent = b14 + b135 + b2345 + b125 Arc hyperbolic sine = b1 + b1235 + b234 + b24 + b1345 + b125 Arc hyperbolic cosine = b1 + b1235 + b14 + b135 + b234 + b125 Arc hyperbolic tangent = b1 + b1235 + b2345 + b1 + b1345 + b125 Arc hyperbolic cotangent = b1 + b1235 + b14 + b135 + b2345 + b125 Radian = b1235 + b1 + b145 Degree = b145 + b15 + b1245 Factorial = b235 Multi arguments functions Sum = b234 + b136 + b134 Max = b134 + b1 + b1346 Min = b134 + b24 + b1345 Number = b1345 + b12 Average = b1 + b1236 + b15 Variance = b1236 + b1 + b1235 Deviation = b145 + b15 + b1236 Combination = b14 + b135 + b134 + b12 Arrangement = b1 + b1235 + b1235 Median = b134 + b15 + b145 Quartile 1 = b12345 + b136 + b1 + b1 Quartile 2 = b12345 + b136 + b1 + b12 Quartile 3 = b12345 + b136 + b1 + b14 Arguments separator = b6 Arguments repetition = b5 + b36 + b4 + b345 Examples 1200 = 1200 : "⠼⠁⠃⠚⠚" 1 200 = 1200 : "⠼⠁⠐⠃⠚⠚" 8.93 = 8.93 : "⠼⠓⠲⠊⠉" operators 8 - 3 - 2 = 3 : "⠼⠓⠐⠤⠼⠉⠐⠤⠼⠃" 3 + 5 = 8 : "⠼⠉ ⠐⠖ ⠼⠑" 9 / 12 = 3 / 4 : "⠼⠊ ⠐⠌ ⠼⠁⠃" 9 / 12 = ¾ : "⠼⠊⠐⠌⠁⠃" 9 / 12 = 3 / 4 : "⠼⠊⠌⠁⠃" 1 - 9 / 12 = 1 / 4 : "⠼⠁ ⠐⠤ ⠼⠊ ⠐⠌ ⠼⠁⠃" <<1/2> + <1/3>> / 1 + 1 = 5 / 12 : "⠷⠷⠼⠁⠐⠌⠃⠾ ⠐⠖ ⠷⠼⠁⠐⠌⠉⠾ ⠐⠌ ⠼⠁⠐⠖⠼⠁⠾" -3 - 2 = -5 : "⠐⠤⠼⠉⠐⠤⠼⠃" 1 + 4! = 25 : "⠼⠁ ⠐⠖ ⠼⠙⠖" (modulus) 3 | 2 = 1 : "⠼⠉ ⠸⠳ ⠼⠃" parenthesis (3 - 1) / (2 + 1) = 2 / 3: "⠐⠣⠼⠉⠐⠤⠼⠁⠐⠜ ⠐⠌ ⠐⠣⠼⠃⠐⠖⠼⠁⠐⠜" (3 - 1) (2 + 1) = 6 : "⠐⠣⠼⠉⠐⠤⠼⠁⠐⠜ ⠐⠣⠼⠃⠐⠖⠼⠁⠐⠜" trigonometric cos(pi/2) = 0 : "⠉⠕⠎ ⠐⠣ ⠘⠏⠐⠌⠼⠃ ⠐⠜" exponent 3^2 = 9 : "⠼⠉⠔⠼⠃" 3^2 + 1 = 10 : "⠼⠉⠔⠼⠃⠐⠖⠼⠁" 2^10 = 1024 : "⠼⠃⠔⠼⠁⠚" others functions 2 * ln(e) = 2 : "⠼⠃ ⠐⠦ ⠇⠝⠐⠣⠑⠐⠜" SQRT 9 = 3 : "⠩⠼⠊⠬" SQRT<9+1> = 3.16 : "⠩⠼⠊⠐⠖⠼⠁⠬" CUBEROOT<8> = 2 : "⠩⠔⠼⠉⠼⠓⠬" cos(pi/2) = 0 : "⠉⠕⠎ ⠐⠣ ⠘⠏⠌⠼⠃ ⠐⠜": pi : "⠘⠏" parameters 3^2 = 27 : "⠼⠉⠔⠼⠉": r+1 = 28 : "⠗ ⠐⠖ ⠼⠁" x = 2 : "⠭ ⠐⠶ ⠼⠃" y = 4 : "⠽ ⠐⠶ ⠼⠙" x^y = 16 : "⠭⠔⠽” 2x = 4 : "⠼⠃⠭" statistics sum(2.5,3) = 11 / 2 : "⠎⠥⠍⠐⠣ ⠼⠃⠲⠑ ⠠ ⠼⠉ ⠐⠜" max(3,4) = 4 : "⠍⠁⠭⠐⠣ ⠼⠉ ⠠ ⠼⠙ ⠐⠜" min(2,6) = 2 : "⠍⠊⠝⠐⠣ ⠼⠃ ⠠ ⠼⠋ ⠐⠜" nbr(1;3;5;7) = 4 : "⠝⠃⠐⠣ ⠼⠁ ⠠ ⠼⠉ ⠠ ⠼⠑ ⠠ ⠼⠛ ⠐⠜" ave(7;13) = 10 : "⠁⠧⠑⠐⠣ ⠼⠛ ⠠ ⠼⠁⠉ ⠐⠜" med(1;3;5;7) = 4 : "⠍⠑⠙⠐⠣ ⠼⠁ ⠠ ⠼⠉ ⠠ ⠼⠑ ⠠ ⠼⠛ ⠐⠜" med(1;2;3;5;7) = 3 :"⠍⠑⠙⠐⠣ ⠼⠁ ⠠ ⠼⠃ ⠠ ⠼⠉ ⠠ ⠼⠑ ⠠ ⠼⠛ ⠐⠜" qua1(1;2;3;5;7) = 2 : "⠟⠥⠁⠁⠐⠣ ⠼⠁ ⠠ ⠼⠃ ⠠ ⠼⠉ ⠠ ⠼⠑ ⠠ ⠼⠛ ⠐⠜" var(2;5) = 2.25 : "⠧⠁⠗⠐⠣ ⠼⠃ ⠠ ⠼⠑ ⠐⠜" dev(2;6) = 2 : "⠙⠑⠧ ⠐⠣ ⠼⠃ ⠠ ⠼⠋ ⠐⠜" comb(96;6) = 927048304 : "⠉⠕⠍⠃ ⠐⠣ ⠼⠊⠋ ⠠ ⠼⠋ ⠐⠜" arr(49;6) = 10068347520 : "⠁⠗⠗ ⠐⠣ ⠼⠙⠊ ⠠ ⠼⠋ ⠐⠜" repetition : sum(2->3;3->6) = 24 : "⠎⠥⠍⠐⠣⠼⠃⠐⠤⠈⠜⠼⠉⠠⠼⠉⠐⠤⠈⠜⠼⠋⠐⠜" ________________ Math computer braille language Generality Spaces are not significant. The uppercase character will be converted to lowercase before analysis. Numbers may be typed as 10 exponents. Example, 2000 is 2e3 and 0.02 is 2e-2. Any character not a command will be detected as a variable then 2a will be detected as 2 times the “a” variable if the variable was defined in the previous paragraph. You may type a=2 2a You have 4 after calculation. The result of the calculation is stored in the “r” variable. so you may chained the calculations using this variable. If the variable has more than 1 character you must use the block label {}. Exemple toto variable is written {toto} For statistical functions you must use the parenthesis block and the semicolon to separate each value. Example : (12; {titi}=(3 - 1) (2 + 1); 45; 1+2; 55) blocks ( ) parenthesis [] bracket {} variable label constants pi 3.14... e 2.7... operator + addition - subtraction * multiplication / division % modulo ^ exponent = affectation one argument functions ln natural logarithm log logarithm base 10 sqrt square root deg degree conversion rad radian conversion ! factorial sin sine cos cosine tan tangent cot cotangent asin arc sine acos arc cosine atan arc tangent acot arc cotangent sh ou sinh hyperbolic sine ch ou cosh hyperbolic cosine th ou tanh hyperbolic tangent coth hyperbolic cotangent ash ou asinh hyperbolic arcsine ach ou acosh hyperbolic arccosine ath ou atanh hyperbolic arctangent acoth hyperbolic arccotangente Note : For exponent on a function you may either use cos^2(45) or cos(45)^2 Several arguments functions nroot nth root nbr number of element max maximum min minimum sum sum ave average qua1 quartile 1 qua2, med quartile 2 or median qua3 quartile 3 var Variance dev Deviation comb Combinaison arr Arrangement ________________ ________________ APPENDIX - USB braille keyboard When the device is connected via USB, the characters and functions of the braille keyboard can be sent in different ways : * USB-HID : The characters and functions are produced the same way as the usual USB keyboard. They can be independent of the operating system or the screenreader used. * Driver: The characters and functions are being sent to the screenreader’s driver. They are definitely dependent on the screenreader used. The screenreader or the software communication of b.note can be used to turn an operating mode into another. However, it is possible to acknowledge the operating system you are in or change it manually in the menu. ________________ APPENDIX - Unimanual braille keyboard The braille keyboard has different operating modes that you can select in the menu Applications settings keyboard>braille. Standard : Anytime you take your fingers off the braille keyboard, the braille combination displayed is the last one typed. However, it is possible to change a combination before releasing the keyboard by changing the pressed keys and waiting a moment before taking your fingers off the full combination. Unimanual 1 : You type the braille dots by several successive or combined presses on the keys, then approve this number of presses with the braille key A. If the A braille key is part of the braille combination, it will have to be typed in combination with another dot, then re-press to approve the combination. Unimanual 2 : It is a faster operating mode as the approval of the code is automatic. The braille display is divided in 2 parts, one part 1,2,3,7,9 and the other part 4,5,6,8,A. You only need to type the first part of the braille combination in one or several presses, then you type just once the second part, and the braille combination will be generated. For braille combinations that only have dots in one part, you need to press the A braille key to approve. Unimanual 3 : This operating mode enables to enter the braille combination using half of the left keyboard part (dots 1,2,3,7). After typing this combination, the second half is typed as follows 1-4, 2-5, 3-6, 7-8, 9-A. The “A” and “9” keys typed with one half, are taken into account as they are. The “9” or “A” keys are used to produce Correction or Space but also to approve the braille combinations that do not have the other half. The “4” key alone permits the typing of the braille combinations that do not have the first half. Unimanual 4 : This operating mode is the same as the previous one but using dots 4,5,6,8,A. In order to type the first half of the combination, we will use the following combination 4-1, 5-2, 6-3, 8-7 and A-9. The braille key 1 will permit the typing of the braille combinations without the first half. APPENDIX - Functions of the routing cursor keys Multiple keyboard actions are possible on routing cursor keys: * Light click (first contact) * Stronger click (second contact) * 2 successive light clicks (double click first contact) * 2 successive stronger clicks (double click second contact) * Click on 2 adjacent routing cursor keys A different function can be assigned to each of these actions. By default, the functions will be as follow : Actions Functions by default Light click on the first routing cursor keys Moving back the braille display Light click on any routing cursor keys Moving forward the braille display Strong click Action at the current position 2 successive light clicks Same function as double click with the mouse. In a text it can select a word for example 2 successive strong clicks Same function as double click with the mouse. In a text it can select a word for example Click on 2 adjacent routing cursor keys Contextual Menu (for screen readers) ________________ APPENDIX - Bluetooth pairing The bluetooth pairing of a device with b.note is quite simple : This bluetooth pairing must be done only once. The device saves a list of paired peripherals. Pairing with a PC * Start b.note and select “bluetooth-applications” in the main menu. * Activate Bluetooth of the PC you want to pair. Then launch a search for a peripheral. b.note must appear under the name “Esys-bnote-xxxxx”. * Launch the pairing by approving the device on the PCl. A serial port is open (COMn on a PC), this port will be used by the screenreader. * Then you can make your b.note invisible if you want. Pairing with a tablet or an Android smartphone * Start b.note and select “bluetooth-applications” in the main menu. * Activate Bluetooth on the tablet, to do so, go to Settings>Connection of the device and select Bluetooth. * In the list of available devices, you must see b.note appear under the name “Esys-bnote-xxxxx”. You must press to launch the pairing. * “Esys-bnote-xxxxx” goes to the list of devices associated. * Then you can make your b.note invisible if you want. Pairing with an Apple tablet or smartphone * Start b.note and select “bluetooth-applications” in the main menu. * on your Apple product go to parameters / accessibility / voice over / braille * In the list of available devices, you must see b.note appear under the name “Esys-bnote-xxxxx”.

APPENDIX - Bluetooth file transfer Transfer from PC to b.note * Check if your b.note is visible in Bluetooth (menu settings>bluetooth in the file explorer of b.note). * Open the Windows files explorer on your PC. * Open the contextual menu on the selected file (right click on the mouse) and select “Send to > Bluetooth peripheral”. You can also select a group of files. * Pick Esys-bnote in the list of proposed devices then click Next. Once received, the file is located in a directory named “bluetooth” on b.note. This location is dedicated to receiving files, so it is necessary to move the files received in a directory of your choice in order to open the file with the editor. It is recommended to keep the directory “My documents/bluetooth” empty because if there is a file in this directory with the same name, it will lead to transfer failure. Note: Sending the file is also accessible with Windows by pressing the Bluetooth icon on the notification bar (systray). After picking the Bluetooth peripheral, the files will have to be selected to be sent. Transfer from b.note to PC ● Go to the file explorer of b.note ● Select the file you want to transfer. It is also possible to select several files for a grouped mailing. ● Select the function of the menu File>Send to. ● Pick the computer’s name that needs to receive the file (from the list of peripherals). ● A dialogue box indicates you need to turn the PC into files inbox mode. On the PC, click on the Bluetooth icon from the notification bar and pick “Receive a file”. Then click Ok on b.note device to launch the transfer. Once the transfer is done, a dialogue box “Save as” opens on the PC, it allows you to choose the directory where you want the received file to be saved.

10 dots braille functions * These combinations are used to generate all keys of a PC keyboard, other than the characters. They are also called bramigraphs. Graph means that the braille dots used to generate any keyboard action, usually have a graphical logic to have a better understanding. Examples : * The “Home” function, that is used to go to the beginning of the line in the editing zone, or at the beginning of a list, can be done by using combination b123A, (dots 1 2 3 at the same time as Space button). Its symmetrical function, end, that is used to go to the end of a line in the editing zone, or at the end of a list, can be done by using symmetrical braille dots, using space as b456A (dots 4 5 6 at the same time as Space button). * The 4 arrow keys can also be generated with 10 dots braille functions. Even though they can be used with the right keypad, it is more convenient to generate them this way with successive shortcuts. You can notice that the 4 arrow keys always use the A key (space), combined with one of the 4 dots of the letter “w” in braille (b2456). The up arrow key will use the top dot of “w”, so you will type b4A ; the down arrow key will use the left dot of “w”, you will type b2A ; and the right arrow key will be b5A. * The functions from F1 to F12 will be generated when using the first 12 letters of the alphabet in combination with braille key 9, for example b19 for F1 up to b1239 for F12.
