BlindShell 2 Baroque User Manual
BlindShell is a touchscreen phone for blind and visually impaired people. It is operated by simple gestures. Feedback is provided by the built-in synthetic voice, by vibration and by additional acoustic signals. BlindShell has been developed in close cooperation with the Czech Blind United (SONS). If you have any suggestions or other feedback regarding BlindShell, please do not hesitate to contact us at email@example.com. Your feedback is very valuable to us and helps us to improve BlindShell.
Setting up the phone
The structure of the phone
Congratulations! You are now holding your first BlindShell phone. Before you start using the phone, we would like to introduce you to the device. Hold your phone in such a way that it is perpendicular and the rear side with the physically distinguishable camera is pointing away from you and the camera is located at the upper end of the phone. BlindShell has two buttons which are located as follows:
- The long button on the left edge is the volume rocker. Pressing the upper end will increase the volume, and pressing the lower end will decrease it. In any text field, a long press on the volume button will start the dictation function.
- The small button on the right edge has three functions. It turns your phone on, it locks the screen and it acts the home button. Pressing the button for half a second from anywhere within BlindShell will take you back to the main menu.
On the upper edge of the phone, you'll find tow sockets. The one in the middle serves for charging the phone and also for connecting the data cable. The round one on the right side of the edge serves for connecting the headset.
Inserting the SIM card and the battery
All BlindShell phones are delivered with the phone itself, the charging cable, the power adapter and a headset. A SIM card is not provided with the phone. You need either a standard SIM card or a micro SIM card. Before you can turn the phone on, you need to insert the battery and the SIM card as follows:
- Hold your phone perpendicular with the rear side pointing towards you and the camera at the upper end.
- Hook your finger nail into the socket in the bottom part of the phone on the left side and pull the rear side away from the device until you hear a clicking sound. Move your finger around the phone through the little crack that has now appeared and remove the rear end completely.
- Put your phone face down on the table so that the sockets are located on the upper edge.
- In the upper third of the phone, you will find three card slots. The left slot is the standard SIM slot, the middle one is the micro SIM slot and the right slot is for a micro SD card which serves as an extension of your phone's memory. Remove the dummy SIM card from the slot which you are going to use, and replace it with your own SIM card. The standard size has a cut off corner on the upper left. The same applies for the micro SD card. The micro SIM card has a cut corner on the bottom right. In BlindShell you can use up to two SIM cards at once. Each SIM card can have assigned one of the following services: Outgoing Calls, Outgoing messages or Mobile data. Calls and messages can be received on both SIM cards at once. The setting of the SIM cards can be found in the Settings - Networks - SIM cards menu.
- Hold the battery perpendicularly and search the short edges for a slightly rough area. Turn the battery in such a way that the rough edge is located on the upper right edge. Now insert the battery until the upper edge touches the card slots. Press down on the protruding lower edge until it fully disappears into the phone.
- Now put the lid back on the phone so that the camera protrudes from the whole, and carefully press down along the edges of the phone until the lid clicks back into place.
Operating the phone
Before you start using the phone, take a few minutes to familiarize yourself with a small number of gestures that enable you to control BlindShell.
BlindShell is operated with just four gestures, so you will only need put in a little effort to be able to handle your phone.
The following gestures ensure full control over your phone:
- A one-finger tap is performed by tapping the screen once. It helps you to navigate through menus and lists. If you tap the left half of the screen, you will move backward, and if you tap on the right half of the screen, you will move forward.
- A one-finger holding gesture is performed by holding your finger on an item for about half a second. Depending on the context, the one finger holding gesture has the following functions:
- Select a list or menu item
- Accept an incoming call
- Confirm a dialogue or question
- Turn off the alarm
- A two-finger tapping gesture is performed by taping on the screen with two fingers. It will allow you to read the item in focus. In a menu, this will be the selected item, in a text field this will be the complete text. The following functions are performed with a two-finger tap:
- Read the item in focus
- Read of a complete text in a text field
- Read the contact name or the caller ID from an incoming call
- Play or pause the book reader
- A two-finger holding gesture can be described as an escape or negation gesture. Place two slightly splayed fingers on the screen for about half a second to perform the following:
- Go back one level
- Answer no to a question
- Decline an incoming call
- Escape from tasks (creating contacts, writing messages, etc.)
Access to status info
Slide one finger from the bottom to the top of the screen and you will receive back status info, e.g. time and date, cell coverage, etc.
Locking and unlocking the phone
Short press of the power button will either lock or unlock the phone, depending on the state in which the phone was before pressing the button.
Slide one finger from the top to the bottom of the phone and you will get quick help, explaining the most important BlindShell gestures.
End a call
A short press on the power button will end a call.
Resetting the phone
If your phone becomes unresponsive or malfunctions, you can reset the phone by holding the power button down for ten seconds.
When the phone is unlocked, pressing the power button for about half a second will always take you back to the main menu. If your phone is locked, pressing the power button for about half a second will wake it up.
Spelling the last utterance
If you perform the two finger tapping gesture twice in a quick succession, the last utterance will be spelled by characters instead of just read. The gesture can be used in keyboard as well when a precise control over input is needed, like with passwords.
To start your phone, press the power button for about half a second. You will get a vibration feedback for confirmation. You will hear a short melodyu when BlindShell has booted up. The phone is ready to use when the first menu item (call 1 of 9) is read back to you. If you are asked for your pin, please enter it. The keyboard has the alpha numeric design used by old phones. Underneath the numbers you will find an additional row with three keys. The function of the middle key will vary depending on the context. However, the left and right buttons always have the following functions:
- Delete, on the right
- Send, Save or Call, on the left
To enter your PIN, find the requested number and hold your finger on it. Tap the screen anywhere with another finger. When you remove both fingers from the screen, you will hear the written number and a typing noise as additional acoustic feedback. In addition, the numbers are read in groups of three. For example when you type 1, 2, 3, 4, each written number will be read back. However after typing 3, you will also hear 1, 2, 3. The function keys are used in the same fashion. Note: If it is necessary to delete everything that you have entered, find the delete key with one finger, hold it down and tap anywhere on the screen until you hear "delete all". When you remove both fingers from the screen, you will be prompted to confirm that you really want to delete all. Confirm this with the one-finger holding gesture.
After you have entered your pin and have selected Use, BlindShell is ready to use.
The virtual keyboard
The virtual keyboard handles the same way as the numeric keyboard that you operated to enter your PIN. However, the layout of the keyboard is different. On key two, for example you will find letters a, b, c and, of course, number 2. If you want to write the word hello, repeat the following steps for each letter:
- With one finger, find the G in the position of number 4.
- Hold your finger on the G and tap the screen anywhere twice with another finger. After the first tap, you will hear G, and after the second tap, you will hear h.
- Remove both fingers from the screen. A clicking sound confirms that the selected letter has been written. After you have repeated this procedure for each letter, the word hello will be read back to you after either a space or a punctuation. If you want to delete the last letter, hold Delete with one finger and tap the screen anywhere with another finger. Removing both fingers from the screen will delete the last letter that was written.
With the # key, you can switch between the numeric keys and the alpha numeric keys and manipulate capitalization. The first letter after any punctuation mark, except a comma, is automatically capitalized.
The QWERTY keyboard is an alternative way to write texts on BlindShell. Some people may find using QWERTY keyboard faster than the traditional one. You can select your prefered keyboard in Settings - Control - Keyboard - Keyboard style.
When you select the QWERTY keyboard, only keyboard screens used for entering the text will be affected, like the SMS or note writing keyboard. The dial screen or the screens for numeric input as well as screens for date and time input will continue using the traditional keyboard layout.
For ergonomic reasons, the QWERTY keyboard has a different orientation than most screens in BlindShell have - it's the screen oriented landscape. The longer side of the phone should be horizontal and the volume rocker should be pointing upwards.
The QWERTY keyboard layout has five rows and ten columns and is akin to the keyboard you might have encountered on a computer. The keyboard has three switchable modes (lowercase letters, uppercase letters and special characters).
The basic layout is the following:
- the topmost row contains numbers 1 to 0
- the second row contains letters only
- the third row contains mostly letters, the last key being reserved for a backspace
- the fourth row starts with the shift key and its last two keys of the row are reserved for arrow keys to navigate within the text
- the last row contains the special character key, spacebar, three punctuation keys and the okay button which submits the text and closes the keyboard
To use the QWERTY keyboard, drag one finger over the screen until you find the key you want to use. Release the key to type it.
In most cases, there will be no need to use the second finger.
There are two exceptions:
- the delete key can alternatively delete by word or delete all
- non-English versions use the second finger to enter accented versions of letters
To trigger the alternate characters or functions, tap your second finger on the screen like when using the classical keyboard. We recommend that you keepenough distance between the first and second finger - you can for example do the second taps with your other hand.
Since there are too many characters to fit on a single keyboard layout, the keyboard can be switched to different modes:
- the default mode is the lowercase mode, it contains lowercase letters and numbers
- the uppercase mode can be triggered by the shift key and contains a selection of most common special characters and punctuations as well as the capital letters
- the continuous uppercase mode can be triggered by the "special characters" key followed by the "shift" key
- the special characters mode contains the rest of punctuation and special characters
- the emoticon mode which contains a selection of smileys and emojis
Instead of a keyboard it is possible to input text via voice dictation. While using a keyboard press either of the volume buttons for about half a second to start this function. After being prompted and hearing the beep cue you can start dictating the text.
Dictate the text in short sentences or in a few words. After each dictated segment the phone will slightly vibrate. At this moment you can either continue in dictating more text or close the voice dictation by long pressing either of the volume buttons, or long pressing the screen. If you don't close the voice dictation function manually, it will be closed automatically after a few seconds.
To use the voice dictation you need to be connected to the Internet.
This feature enables you to control the phone by voice commands. To turn on the assistant, long press one of the volume buttons for a duration of at least 1 second (those are the buttons placed on the left edge of the phone).
Through this feature you will be able to open any application that is present in the phone by simply saying its name. For example to open the application Messages, you can turn on the voice assistant and utter “Open the messages application”, “Write a message”, “Open messages”, “Messages” and so on.
Full list of the applications currently supported by the voice assistant is following: Calls, Messages, E-mail, Weather, Alarm, Minute Timer, Calculator, Calendar, Notes, Internet Radio, Media Player, Books, Color indicator, Magnifying glass, Voice Recorder, Localization, Turning off the phone, Facebook, WhatsApp, Internet Browser and TapTapSee.

In this folder, you will find the following applications:
- Web Browser
- What's App
All applications have been tested with BlindShell and are considered to be usable. However, as all applications in this folder are third party applications, we don't guarantee full accessibility or functionality. There are two styles which can be used to control the Android applications: BlindShell gestures or Android TalkBack. You can switch between those styles in the menu Settings - Control.
The first control style is based on the control of the BlindShell phone itself. Text is input via BlindShell keyboard and following gestrues are used to control the applications:
- Short tap with one finger in the right side of the screen will move you to the next element on the screen
- Short tap with one finger in the left side of the screen will move you to the previous element on the screen
- Long press with one finger is used to select or confirm
- Long press with two fingers is used to go to the previous screen, to cancel a selection or leaving the keyboard
- Short tap with two fingers will read the last information or current selected element
- Swiping one finger from the top to the bottom of the screen will bring up a global context menu with other options (go to the top, go to the bottom, continuous reading, repeat last utterance, spell the last utterance)
- Swiping one finger from the bottom to the top of the screen will bring up a local context menu with other options (this function will be mostly used in the itnernet browser)
Voice call in WhatsApp and Facebook Messenger
Voice calls in WhatsApp and Messenger are supported. An incomming call can be accepted by a power button short press and rejected by the two finger long press gesture. A call that's in progress can be hung up by a power button short press or two finger long press gesture.
The second control style is a native screen reader of the Android OS - TalkBack. When you choose this control style a native Android keyboard will be used for text input as well. The TalkBack control style is described on the following support Google website: https://support.google.com/accessibility/android/answer/6283677?hl=en
In this folder, you will find the following helpers that might come in handy.
- Color Detection
- Illumination sensor
- Banknote recognition
- Text recognition
- Object tagging
- Open the application and wait until you hear that the application is prepared.
- Hold the camera a few centimeters from the scanned object and start the recognition process with the one-finger holding gesture. As color recognition is done with the help of the camera, note that several factors affect the result, e.g. ambient light, the angle of the camera, etc.
- The color will be read out as soon as the recognition process is finished.
- A two-finger tap will repeat the color.
The illumination sensor is located in the top left corner of the device.
- Open the application.
- The ambient light intensity is indicated by the rate of clicking.
- A higher rate of clicking indicates brighter environment, a lower rate indicates darker environment.
- A short tap with two fingers will produce the illumination level as a percentage and a verbal description of the intensity.
- Open the application.
- To change the standard currency, use the one-finger holding gesture to open the currency settings.
- Follow the prompted instructions to scan your bill. As soon as the bill is recognized, its value will be read back.
- During the recognition you might be promted to flip the banknote. In such case present the other side of the banknote to the camera.
When the magnifier application is in use, the phone will be continuously capturing the image from the rear camera and displaying a magnified version of this image on the phone screen.
- Open the magnifier application.
- You can adjust the magnification level with a single tap on the screen. Tapping on the top part of the screen will zoom out, tapping on the bottom part of the screne will zoom in.
- The one-finger holding gesture opens a sub menu offering the following choices:
- Pause picture
- Turn on/off the light
- Color inversion
- The magnifier has an auto-focusing function. When the image is being focused a high-pitched beep can be heard. You can also trigger the focus action manually by tapping on the device body or giving it a gentle shake.
For more convenience, we have designed a special phone holder to be used with this function. It can be purchased separately.
The Localization app will help you find the address of your current location. It can use both Wi-fi and Mobile data.
- Open the Localization app.
- The localization process starts immediately saying Loading and may last up to 30 seconds.
- If the process is successful the address will be read back to you.
- The accuracy depends on a quality of your connection.
- In case of an error the app will read Service not available.
- After running the application, hold the phone in landscape orientation and point it towards where you expect the text.
- Optimal distance from the object with text is about 15-20 centimeters, but it may vary depending on font size and other factors.
- The application will announce any text it finds aloud, this is called orientation mode and will help you find the text you are interested in. During this mode, you can tap the screen to restart reading - this is useful when you move the phone a lot and don't want to listen to text previously captured.
- If the application detects some text but has a problem reading it, the text may be upside down. You will be notified about this situation and you can react by rotating the object by 180 degrees.
- Perform a one finger holding gesture or press the volume button for a short time to capture current text for thorough recognition. If the internet is available, more precise on-line recognition engine will be used. In the thorough mode, you will be presented with a list and you can browse the text line by line, like any other list in BlindShell.
The object tagging function can help you tag and later identify objects that are otherwise hard to tell apart by touch - like bags or boxes with spices, cosmetic and household cleaning products, bottles, cans and so on. For this function you will need coded tags that can be purchased separately from your BlindShell distributors.
The tags are squares stickers about one inch by one inch. They have to be peeled of the sheet and stuck on the object you want to tag. The tags are to be read by the phone's back camera lense. Each tag is unique and when you tag an object, your phone will associate that tag with your spoken or written description. Later on, when you read the tag again, the description will be played back to you.
- Pick an object you want to tag.
- Peel one square tag off the sheet with tags and stick it to the object. If possible, avoid sticking the tag on rough or curved parts of objects.
- Open the tagging application and select the "add tag" option. Periodic tapping starts, informing you that the detection is running.
- Point the camera of your phone towards the tag on your object. The recommended distance is around 20 to 30 centimeters or inches. It may take some practice to get it right.
- After the tag is read, you will be asked if you want to record or write a description. If you choose to record, the recording will start after a beep and will automatically finish after five seconds. If you choose to type, a standard keyboard will appear and you will be able to input the description this way.
- Select the "read tags" option from the menu, the phone will start tapping periodically once the camera is ready for tag reading.
- Point your phone camera towards the tag like when tagging a new object
- Once the tag is read, the camera mode will be paused and the description will be read back to you
- Long press with one finger will return you to the camera mode for another tag. The description can be repeated with two fingers short tap.
The "list tags" option in the menu brings you to the list of your tagged objects. Here you can edit descriptions or delete a tag that is no longer in use.

- Reading when deleting characters with the available options Read next character or Read deleted character.
- You can turn off touch with second finger: If this option is activated, you don't need the second finger to confirm a typed letter. The letter will be written after one finger has been removed from the screen. This option requires that you find the letters while sliding one finger over the screen. The second finger is needed only to find the next letter on a key For example, you have to tap P three times to find R, but if you just want to write P, you slide over the keyboard until you find it. When you remove your finger, P will immediately be written.
- Set feedback options

In this section you can set up wi-fi, configure your SIM cards if you use two SIM cards at a time, or turn the mobile data on and off.
In this section you can enable or disable Wi-Fi, connect your phone to a Wi-Fi, or edit the list of known Wi-Fi networks.
- To connect to a network Wifi has to be enabled.
- Network list contains a list of all available networks. Select a network to connect to it.
- You will be prompted to enter a password if the network is password protected.
- You can also connect to a network using a WPS button on the network's router.
- If your network has hidden SSID, you can connect to it via the Connect to hidden network option.
- To remove a saved network from the list, go to the network list, select the respective network and choose forget network.
- Users can connect their phone to PC via a cable and create a plaintext file in the root folder of the storage.
- The name of this file is wifi.txt (case-insensitive) and it contains two lines.
- The first line of this file is the name of the network (case insensitive) and the second line is the password (case-sensitive).
- Every time an attempt to connect to an encrypted network is made from the BlindShell menu, BlindShell will check for presence and correct format of this file.
- If it's alright it will compare if the first line with the network name if it matches the network selected.
- If so, the password keyboard won't even be shown and the password from the file will be used instead.
The phone supports certain Bluetooth devices, namely audio devices (speakers, headphones, handsfree) and external QWERTY keyboards.
A new device has to be paired before it can be used for the first time.
Warning: If you connect an audio device, your audio output (including the synthetic voice) will be played through that audio device. If the device fails to function properly, you might end up without any useful feedback. In that case you can always disconnect a faulty audio device by raising the volume beyond the maximum level, i.e. pressing the volume button few times in a rapid succession.
The Bluetooth function is off by default. This helps to save energy of your battery. We recommend that you turn Bluetooth off if you don't use it. You can turn Bluetooth on and off using the first option in the menu.
- Enable the pairing mode on your device. Some devices are in the pairing mode by default when turned on and out of signal. Other devices have a special key or combination of keys that will trigger the pairing mode. This is device-specific and can be found in the manual of the device.
- Once your external device is in the pairing mode, select the "Scan for devices" option in the menu. The scan will take up to half a minute after which a list of nearby devices will be presented to you.
- A long press with one finger gesture on the selected device will trigger the pairing process. This will generally take few seconds.
- In some devices, usually keyboards, you may be asked to enter a verification code. If this happens, you need to type a code given by BlindShell on your external device and confirm it by the Enter key.
A newly paired device should be generally connected automatically. However, this is not the case with all devices. Sometimes it's also useful to be able to connect and disconnect devices at will, without pairing and unpairing them.
To connect or disconnect a device:
- Select the "Paired devices" menu item, allpaired devices will appear in this menu
- A long press with one finger on a device will open a menu where you can select an operation to do with your device (connect, disconnect, unpair)
- If you choose connect or disconnect, an attempt to connect or disconnect a device will be made. Once it succeeds, the device will assume it's function (the sound output will be redirected, the arrow keys on a keyboard will become available for menu navigation)
- If you choose to unpair a device, this device will become unavailable until you pair it again. Some devices may require this action before they can be connected to another phone.
- Before you can connect a paired device, you usually need to turn it on by a switch on the device. Some devices may turn themselves off after a period of inactivity.
- You can use numbers on your Bluetooth keyboard for faster menu navigation. If you press a number key while in a menu, BlindShell will jump to the corresponding item directly.
- There is a vast number of Bluetooth devices on the market. BlindShell cannot guarantee compatibility with every device available. Your BlindShell vendor might be able to give you an advice or offer you a tested model.
- Due to possible radio interference and due to nature of the Bluetooth protocol itself, there is no guarantee that a device will be found during the scan procedure. If you can't see or pair your device, make sure it's still in the pairing mode and then try the procedure again. If the problem prevails, make sure there is no strong source of interference in your area, like another Bluetooth device, a WiFi router or some other radio device in a close proximity.
- Mobile data can be turned on and off by selecting the item.
- You can activate or deactivate the request for PIN code at the phone startup in the PIN code menu. To change the PIN code you need to activate it first.
- If you enter the PIN code incorrectly three times in a row, your SIM card will be temporarily blocked and PUK code will be requested. If you enter the PUK code incorrectly ten times in a row, your SIM card will be blocked permanently.
- If you use two SIM cards, select the respective SIM card prior to changing, enabling, or disabling the PIN code.
- This option will be visible only when there are two SIM cards used in the phone.
- You can select preferred SIM card for outgoing calls, outgoing messages, or data transfers.
Google Account log-in
- By selecting this option you can login into an existing Google Account or create a new one.
- After logging in your newly added contacts will be automatically saved into your google account and you will have access to your Google contacts.
- Such contacts will be later available on other devices as well, when logged in with your Google account.
In this section, you can check BlindShell for updates and install selected updates. The update process is read back to the user, so no sighted assistance is necessary.
- Check for updates checks for the latest updates
- Install update guides you through the installation process.
- Throughout the update process the phone will be using different voice.
Time and date settings
- Time and date are automatically set from the network, when SIM card is inserted in the phone. However you can change the settings here.
- Chose the item you want to set: hour, minute, day, month, year, and enter the required information. Please note that each information item, except for the year, has to be entered in two digits. The year has to be entered in four digits.
- All information has to be saved before the next option can be set.
- When leaving the date or time settings, you have to choose whether you want to save or dismiss your settings.
If you want to turn off your phone, choose this option and confirm that you want to do so with another long press.
Among others, status information supplies information about:
- Date and time (long press is a shortcut to calendar)
- Information about WiFi (long press is a shortcut to WiFi settings)
- Signal strength and mobile data info
- Battery state
- Information about Bluetooth (long press is a shortcut to Bluetooth settings)
You can access the status menu either by selecting "Status information" the main menu or by sliding one finger from the bottom to the top of the screen. You always exit the status info menu with the escape gesture, i.e. with the two-finger holding gesture.
BlindShell comes with a built-in manual which you will find in the main menu. If you need more specific help, slide one finger from the top to the bottom of the screen when you need help and you will be offered more context-based help.
Tutorial is launched on the very first start of the phone. It will teach you everything you need to control the phone. It will finish after completion of all the tasks. In case of need it can be finished manually by pressing the power button for three times in a row. Tutorial can be restarted from the Manual menu of the phone.
In the favorite contacts menu, you will find important contacts that you have specified as favorites. Selecting one of these contacts offers the same options as you would get if you were to access them through the contacts list.
