Project BrailleScript

• Advisor Dr. Mayer Goldberg
• Team Semyon Medvedik
• Ivan Golman
• Ruslan Sergienko

2
Project Goals

• Create Braille Transcription Platform, that
• Provides advanced text editor functionality
• Requires no expert knowledge in Braille
• Provides Math Transcription Module
• Supports future developed Modules integration
• Is Free of Charge (GPL)

3
System Requirements Overview

• Plain/Braille text typing and editing required
  for the production of regular Braille documents.
• Advanced text formatting required for the
  production of fine formatted (e.g. Science/Music
  related) Braille documents.
• In Braille entry mode the system will emulate a
  standard Braille keyboard, allowing for input of
  special Braille codes that are not available from
  the standard QWERTY or native-language keyboard.

4
System Requirements Overview (cont.)

• Intuitive and user-friendly Graphical User
  Interface for domain-specific Braille (such as
  mathematics and music), that will require neither
  advanced computer skills nor esoteric Braille
  training.
• Insertion of scientific formulae via installed
  Math transcription module.
• The platform will be designed to allow for
  additional domain-specific functionality to be
  added via external modules/plugins, including,
  e.g. a graphical interface for editing
  mathematics and support for the Braille standard
  for music.

Testing Overview

• For the system components with the highest risk
  of failure the test scripts will be written and
  automated testing technique will be used.
• Functional requirements concerning text editing,
  text formatting and data management will be
  tested as follows
• Generating random user input sequence in the form
  of consequence calls to appropriate methods
• text selection
• text insertion
• text deletion
• changing fonts and styles
• caret position change

17
Testing Overview (cont.)

• Generating a test script which will initialize
  the System and run the input sequence provided
  over the System.
• During the System initialization a new
  BrailleDocument object will be created and all
  input sequence will be run on it.
• During the input sequence run all System messages
  and errors will be logged.
• After the input sequence finish updated
  BrailleDocument object under test will be
  converted to proprietary format and saved on
  disk.
• Saved file will be loaded and new BrailleDocument
  object will be created.
• Two BrailleDocument objects will be compared.

18
Testing Overview (cont.)

• Functional requirements concerning Downloads and
  Installation Management will be tested as
  follows
• Test script will be written which will initialize
  the System and perform the following operations,
  logging all System messages and errors.
• Establish connection with Project repository
  Server using IP address provided by System
  Configuration Management Component.
• Establish connection with Project repository
  Server using IP address provided by System
  Configuration Management Component.
• Downloads selected module(s) to System Modules
  Repository
• Installs (Register) downloaded module(s) into
  System.
• Updates System Configuration.
• Loads one of downloaded modules as Current Active
  module.
