1. Introduction

Braille Me is a sleek, portable and lightweight smart braille display. It is a competent

device specially designed for Visually impaired students and professionals.

With its revolutionary Braille cell technology, Braille Me is highly compact and cost-

effective. At Innovision, we understand the challenges faced daily by students and

professionals, and keeping their recommendations in mind, we have built Braille Me.

Image of Braille Me in isometric view

Braille Me is a compact smart braille display with the following capabilities:

• A line of 20 braille cells with pins that arrange into the required pattern to accurately

represent any six-dot braille code, in any language.

• Capable of reading the contents of files on an SD card for Stand-Alone mode.

• Remote connectivity to PCs and mobile devices for use with a screen reader

• Simple editing functions

It operates in 2 ways –Standalone reader mode and remote mode.

Standalone reader mode:

In this mode, Braille Me displays the content of files stored on an SD card. It does not do

any translation or interpretation. You prepare the files ahead of time on your computer,

then store them on SD card. For example, if you want to read in UEB, prepare the UEB

transcribed title on your computer and then store it on the card. To facilitate this

conversion, Innovision provides a simple software –Braille Me translator.

Remote mode:

You can connect the device to a computer/smartphone/tablet using either Bluetooth

or USB. Once connected, you can navigate, read and edit the content present on the

connected device through Braille Me seamlessly. You can also read books on your

smartphone from Kindle, iBooks, Bookshare, etc.

1.1 Features of Braille Me

Six - dot 20 braille cells with paper like feel

6 key perkins keypad

Removable battery lasting for 10 hours on continuous usage

Upto 32 GB storage through captive SD card

Support for 40+ languages

Remote connectivity to PCs and Smartphones through Bluetooth and USB

Notepad with several editing and navigation functions

1.2 Document conventions

For consistency and clarity, this documentation uses the following conventions.

Braille keys are indicated by number. For example, if the documentation reads Dot 1,

then it means it implies the button corresponding to Dot 1. If multiple braille keys are

required, the documentation indicates those keys by showing the numbers separated

by a space like this: Dots 1 5.

When modifier keys are used, the documentation separates the modifiers from the rest

of the keys with a plus (+) sign like this: Space + Dot 1. Recall that modifiers, like the Shift

key on a regular QWERTY keyboard, are keys you hold down while pressing another key.

This modifies the effect of the pressed key.

When any key combination is pressed, note that the command is executed only when

all the keys are released, i.e., If a user presses space + dot 2 3 to execute a particular

command then until all the keys - space, dot 2 and dot 3 are released the command

will remain on the waiting list and as soon as they are released the command will be

executed. On a braille keyboard, Space is often used as a modifier to alter the effect

of the input keys.

In the descriptions of each Menu option, this documentation indicates the default

setting. Messages, menu items or errors displayed on the braille display are denoted

within quotation marks.

There are 2 types of messages in the software –notifications and errors denoted in the

document using quotation marks.

Errors occur when there is a difference in the expected user input or any of the internal

systems have failed.

Notifications are messages which are intended to inform of any changes to the system.

1.3 Inside the box

Braille Me comes with peripheral devices which are to be used along with Braille Me.

The box contains the following items:

Braille Me

Printed User guide

Braille User guide

Standard –A to Micro-B USB cable

AC charger

SD card pre inserted in your Braille Me

2. Orientation

Orientation to the positioning of buttons, keys, cells, and slots is essential for

understanding how the device operates and how you input and receive information on

the device.

To begin exploration of Braille Me, place the device on a flat surface in front of you with

the row of braille cells farther away from you and the sloping edge nearer to you. This is

the proper operational orientation.

Image of braille Me in top view

Henceforth the guide will refer to this orientation to indicate the position of keys and

slots.

On the right face of the device, you would find a circular button closest to you. This is a

toggle button to power On/Off Braille Me. Going forward on the right face we will find

two ports –A DC jack and a USB slot.

Drawing of the right face of Braille Me

The DC jack is used to insert the power cord from the charger and is positioned just

beside the power button. The USB slot is farthest from you and is used to connect to PCs

via a Standard-A to Micro-B USB cable.

Moving on to the top face, you will find a braille display of 20 cells farthest away from

you. The texture of the braille display area is smoother compared to the body, and it will

have many holes for braille pins. It is accompanied by 20 cursor routing buttons below

each cell.

On both the sides of the braille display, we have a couple of keys used for navigation.

On the right side we have the panning keys named RightUp and RightDown and on the

left side the next item button named LeftDown and previous item button named

LeftUp.

As we move towards the lower section from the braille display we have a Perkins style

keypad which has 6 keys ergonomically arranged representing the six dots of braille.

Dots 3 2 1 on the left and Dots 4 5 6 on the right. It is accompanied by a space bar

which is located in the below these 6 keys in the middle.

Drawing of top face of braille Me

On the right side of the space bar we have the enter key and on the left side back key.

This concludes our top face. On the left face there is a slot for inserting an SD card.

When you receive the device, it would already have a 4GB SD card inserted.

The SD card slot is a standard slot with spring feedback. The SD card is inserted with the

card connector fingers facing upward. To release the card, press in and remove your

finger to allow the card to pop out.

On the bottom of the device a battery compartment is present which is secured with a

set of 4 screws.

3. Powering the device

This section explains how to charge and how to turn on & off the device. Refer to

subsequent section for additional support. BrailleMe has two modes: a Stand-Alone

mode and a Remote mode. In the Stand-Alone mode, the device is a book reader that

uses an SD card as the reading media. In the Remote mode, the device works like other

braille displays and needs to be connected to a computer/smartphone/tablet and a

screen reader. This section explains how to charge, turn the device on and off, insert

the SD card, and enter and exit the menus. Refer to the following sections for additional

support.

3.1. Powering On/Off

To turn on the device just press the power button for 1 sec and instantly the device will

boot and you would hear an audio notification –a short beep. Along with this beep,

the braille display will get activated, and all dots will toggle up and down. Post this

toggling the braille display will show “menu.” As soon as “menu” is displayed, you can

start your work. This entire process should take less than four secs.

There are two ways of shutting down the device. One way is to long press the power

button for three secs and the second is by using the shutdown menu item in the menu.

While using the power button to turn off a double beep is given and in the case of

shutdown menu item a long beep is given. After the beeps all the dots will move down.

3.2. Charging

When you receive Braille Me, it may already have some charge; however, we

recommend charging it fully before or during first use. You can use the device and

charge it at the same time, so this does not hinder your reading time.

When the battery in the Braille Me gets to 15% and 7%, you will receive a notification

indicating that battery is low. At 2% charge, the battery shuts down without notification.

During shutting down Braille Me give a long beep, and all the braille dots will move

down.

To charge the device, use the AC adapter provided. Insert the power cord into the AC

adapter and the circular DC jack into the device. Make sure the AC plug is firmly held

in the slot. If the device is powered on, you could check the charging status under

battery level in the menu. Also, when in power ON state when the charging is complete

a notification will appear indicating battery level full. If the charger is not right or

damaged, the device will notify with the message “invalid charger”. Please use only

the charger supplied with the device. If the device is powered off, no charging

indication will be displayed.

Please note USB charging is not supported and any attempts to do so might damage

the device.

If you have charged the device for 1 or more hours, and it doesn't turn on, contact

Customer Care at +91-8291406811 or customercare@innovisiontech.co.

4. Menu system

An informative yet straightforward menu system is implemented which will help you

explore all the functions and settings. At a time only one menu item is displayed. To use

the device, Braille Me has a set of universal commands which work throughout the

menu system and in its different applications.

Action

Universal command

To go inside/ select a menu item

Enter key

To go 1 step back in the menu hierarchy

Back key

Navigate to the next/ previous menu item

LeftUp/ LeftDown

To Pan left to right

RightUp/ RightDown

Apart from the above-listed commands, you may also need to use the cursor routing

functions to edit names and messages.

Before we go forward let’s understand a few concepts:

4.1. Panning Keys

The Panning keys are keys found on the right side of the braille display. These keys

control how you read the content in a single line of text. A line might have more than 20

letters hence all the letters cannot be to read at once on the 20 cell braille display. So,

to read the contents of the line beyond the 20 characters; you will require moving back

and forth using the panning keys. To read the subsequent 20 characters (panning
