This log intends to provide an overview of the proposed solution, thereby fulfilling a gap in current market available devices. It addresses the main factors around which the usage of braille is dependent upon.

• The pre-installed accessibility options is a major help while using touch-screen based phones. However, feeding text still remains a challenge for those who haven't caught up with technology.
  
  Current Solutions:
  1) Text-over-voiceWith an accuracy of 86 percent [source] this is not a good option when it comes to keeping user experience personalized. Even if this solution is improved upon, listening to or typing private messages isn’t ideal in public places.
  2) Screen Typewriters Screen typewriters are difficult to use with 3rd party applications like WhatsApp. Other disadvantages like lack of non-visual cues are highlighted in the reference paper.mBrailler: Multimodal Braille Keyboard for Android
  3) Physical Keyboard
  a) Braille Penb) Human Ware [http://www.apple.com/accessibility/ios/braille-display.html ]While physical keyboards are better alternatives as to screen typewriters, the devices do not appreciate high typing speeds. These devices are originally meant for desktop/laptop applications and would be bulky to be carried and used with a Smartphone.
  
  Accessibility devices like those mentioned above cost upwards of hundreds of dollars, sometimes even thousands.
  
  
  Proposed Solution:Designing form factorThe proposed solution is a wireless Bluetooth device which sits on the back of a phone within the reach of fingers. While the fingers are used for key presses, the thumb holds the phone in place. The arrangement ensures quick access to Braille keypad, while keeping the experience personalised.
  
  The keypad has 6 key Braille input arranged in a standard Braille line, with delete, space and backspace ergonomically located below the keys. Since the pad is facing away from the user, the key’s numbered as mirror image.
  Advantages:

1)  EASY INTERFACE: The keypad uses BLE nano by Redbear Labs [http://redbearlab.com/blenano/] which acts as a Bluetooth HID device. Therefore, the keypad does not require any drivers or software to be installed onto the computer & can act as a direct replacement for a normal keyboard. This feature also makes it compatible with 3rd party applications.

2)  IMPROVED TYPING SPEED: The keyboard provides a tactile benefit of Braille typewriters. This will have a positive impact on words per minute (WPM) count.

3) PORTABLE: The keypad is sleek and can also easily fit in a pocket.
