14. Utility

The utility menu provides several special functions for use with the Braille Sense.  The utility menu has the following items:

 Calculator, (where you can do simple math equations as well as scientific calculations), set date and time, (where you can set the Braille Sense internal clock), check date and time, (where you can check the date and time), check power status, (where you can check the remaining battery power), setup Internet, (where you can adjust your Internet settings), terminal for screen reader, (which allows you to connect the Braille Sense to your PC for use as a Braille display, external speaker, as well as many other useful functions).  To access the menu items, press space-1 or space-4 in the program menu, and press enter on the utility menu.  Or, you can press u (dots 1-3-6) in the program menu to open the utility menu.  The utility menu has several submenus under each of the menu items.   The following sections will discuss each of these menu options and their functions in greater detail.

14.1 Calculator 

Using the calculator on the Braille Sense you can do simple math equations as well as complex scientific calculations.  The results and formulas will be displayed in Braille, and spoken by the Braille Sense.  While using the calculator, you can refer to the help menu by pressing space-h (dots 1-2-5).  The help menu is very useful as you can quickly access hot key information for the various programs on the Braille Sense.

When you want to use the calculator you can press c (dots 1-4) from within the utility menu.  When using the calculator on the Braille Sense, you need to type using computer Braille when calculating or inserting your formulas.  You can initialize your calculation line by pressing backspace-c (dots 1-4).  If you insert numbers or a function into a result, the result will disappear; and if you put in operators, you can get to the next step.  In addition, you can keep your result in the calculators memory, and you can recall it when you need the result.  You can use the function and operators via the calculator menu or you can use the hot keys depending on which method works best for you.
All of these functions are explained in greater detail below.

14.1.1 General Functions

General functions is a dialog box that contains the basic operator list, a confirm button, and a cancel button.  In the dialog box, you can navigate through the items with tab (space-4-5) and shift-tab (space-1-2).  In the operator list, you can navigate the operators using space-1 or space-4.  Or, in the list, you can press the first letter of the operator that you want to go to.  In the calculator, you can open the menu by pressing space-m (dots 1-3-4) or F2, and press enter on general functions.  Or, you can press g (dots 1-2-4-5) in the menu to access general functions.  After starting the calculation, 0 will be displayed in computer Braille.  On the calculation line, you can access the general functions by pressing enter-g (dots 1-2-4-5).  If the dialog box pops up first, you will be placed on the operator list.  Once in the list, you can select what you want, and press enter on it to run the operator since the default is set to the confirm button in the dialog.  In the dialog box, you can cancel the operator selection by pressing enter on cancel, space-z (dots 1-3-5-6), or space-e (dots 1-5).  You can use hot keys of the operators for convenient access.  
The hot keys of the operators are as follows:

Plus:  dots 3-4-6
Minus:  dots 3-6
Division:  dots 3-4
Multiplication:  dots 1-6
Percent:  dots 1-4-6
Power:  Backspace-4-5
Square Root:  Enter-q (dots 1-2-3-4-5)
Decimal point:  dots 4-6
Left parenthesis:  dots 1-2-3-5-6
Right parenthesis:  dots 2-3-4-5-6
PI:  Enter-p (dots 1-2-3-4)
Exponential function:  Enter-e (dots 1-5)
If you want to enter in negative numbers, you should type in minus (dots 3-6) and the number together in parentheses.  For example, you should type in minus 2 in the following manner:  (-2).  

For the percent operation, you can get the result when you put in the numbers first and the percent sign (%) just after typing in the numbers.  Immediately after you have typed in the percent sign (%), the number that you have typed in will be converted into a percent value.  For example, 90 + 20% equals 90 + 18.  You will see the number 18 on pressing the % sign since 18 is 20% of 90.   So, you get 108 for your answer.

14.1.2 Variable Calculators

The variable calculators will keep your resulting answers and calculations in the memory.  The variable calculators menu has four submenu items:  recall item, delete all saved items, save item, and statistics functions.  You can move between these items by pressing space-4 or space-1 repeatedly, and then press enter on the desired feature.  To access these menu items, press space-m (dots 1-3-4) to call up the menu, and press enter on variable calculators.  Or, you can press v (dots 1-2-3-6) when you are in the menu.

14.1.2.1 Recall Items

Recall items is a dialog box, that has the following items list, delete, display detail, a confirm button, and a cancel button.  You can navigate through each of these items by pressing tab (space-4-5) or shift-tab (space-1-2).  You can access recall items by pressing r (dots 1-2-3-5) in the variable calculators menu.  Otherwise, you can access the dialog box by pressing backspace-r (dots 1-2-3-5) in the calculation line.  The item list displays an item name: the result value, and you can move in the item name list by pressing space-1 or space-4.  You can insert the items result into your calculation if you press enter on the item name.  You can also copy each item in the item list.  Press the space key to select an item in the item list.  Then, press enter-i (dots 2-4) to copy the selected items to the clipboard.  The display detail shows the item name and its result with the default set to no.  If you want to review the detailed information, press space to switch to yes.  Then, it will display "item name: the formula = its result value" in Braille.  Delete is used to get rid of your registered item.  If you want to delete an item, first, you should select the item that you want to be deleted, and then press enter on delete.  You can find the deleted item in item list by pressing tab (space-4-5).  Or, you can press space-d (dots 1-4-5) on what you want to delete in the item name list.  If you want to delete all of the items, you can select all of them by pressing enter-a (dot 1), and press space-d (dots 1-4-5).  If you only want to delete some of them, you can select the items by pressing space, and press space-d (dots 1-4-5) on the selected items.  

14.1.2.2 Delete All Saved Items

When you use this function, you can delete all of the saved items that are stored in the recall items.  To activate it, you can call up the menu by pressing space-m (dots 1-3-4) or press F2.  Then, use the up and down arrows to get to the variable calculators menu, and press enter.  Next, use the up and down arrows to go to delete all saved items, and press enter.

14.13 Backup/Restore Option

Backup/restore option setting is a program where you can backup/restore the option settings for each program in the Braille Sense all at once. This program can be found in the utility menu. You can run this program by pressing k (dots 1-3) in the utility menu. If you run this program, a dialog box will be opened. This dialog box contains: program option check box list, select all button, backup button, restore button, and cancel button. You can move between the check boxes in the program option list, by pressing space-1 or space-4.  You can move between these controls by pressing tab (space-4-5) or shift-tab (space-1-2).  The program option check box list contains option settings, file manager option, word processor option, address manager option, schedule manager option, media player option, web browser option, e-mail option, messenger option, and database manager option. 

In this list, you move to the program option and check it by pressing space. If you want to uncheck it you can do so by pressing space again. After you select all the options you want to backup or restore, press enter on the backup or restore button. If you want to select all of the programs in the list, press enter on the select all button. If you press enter on backup or restore button, the dialog box will be closed. The backed up options will be saved to the flashdisk/database/option folder as files with the same names as each program. 

If you press a backup button, it lets you see a list in which you can select a path where to store a backup file. It shows up flashdisk as default values. Here you move to disk or folder where you want to store a file, by using navigation key in a file manager program. And you select a folder or disk by pressing space, press enter, it turns up that a backup file is stored in selected folder. Each one of these options has its own backup file. This means that when you backup each of the 5 options, it will generate 5 backup files. If you need to store a backup file in a root of disk, refer to this way. When it comes out a name of disk, you press enter after selecting a disk by pressing space. If you press a restore button, it lets you see a list in which you can select a path where to restore a backup file. A way how to move or select a folder or disk is the same as backup. If you select a folder that is not back upped, you can be seen a message which tells that there is no backup option file.

If you cold reset your Braille Sense, or its battery is fully discharged, the main option settings and settings for each program will be lost, and initialized to the default values. If you backup options using this program right before you cold reset, you can restore the option settings you set previously. 

14.14 Upgrade Braille sense OS

If you activate this function, you can update the Braille Sense either through an Internet connection or from a disk that contains the upgrade file.  If you decide to upgrade using an Internet connection, you must first complete the setup Internet function.  If you update the Braille Sense, all of the settings will be returned to their default status.  Data in the flashdisk will be protected.
