Writing the scrum report

As we have to write the scrum report of the assignment, I hope the following links would be helpful for you guys also. https://www.getzephyr.com/insights/best-way-do-agile-project-reporting

Novel Methodology for Kannada Braille to Speech Translation using Image Processing on FPGA

Kannada is another language used by Indians. A set if Indians scientist are researching to develop a Novel methodology for Kannada Braille to speech Translation using Image Processing on FPGA. Their main aim of this research is to convert Braille which is printed on a sheet of paper, to its equivalent Kannada script. The steps of the project work include procurement of RGB image of the Braille character, conversion of RGB image, Extraction of braille character using auto thresholding based on histogram, noise removal, counting of dots and then identification of Braille character based on unique grouping. For the image processing task, a Spartan 3e series of FPGA has used and the output is from both text and speech. The novel algorithm for this purpose has implemented using Verilog HDL language.

Braille self learning tutor with text to speech technology

Blind Aid: A Self-Learning Braille System is the only Braille system that is capable to enhance the Braille writing and reading skills of a visually impaired individual without the need of a teacher. The designed system works on the text-to-speech technology and is capable to read documents. There are different and also popular devices for visually impaired people such as Speech Assisted Learning (SAL), Book Sense Reader, Eye-Pal Reader series, Electronic Braille pad and etc. There are also some web browsers like Audio-haptic internet browser and associated tools specially designed for visually impaired people to help them in internet surfing. This proposed device is user friendly Braille writing and reading tutor with the capability of reading documents and works on text-to-speech technology which is the assistive technology for visually impaired individuals. Process of this system is, the input can be provided by either typing through the provided Braille keyboard, or inserting text ...

Touchpad for the Blind to read text documents

Another project based on Image processing techniques is the  Touchpad for the Blind to read text documents done by the scientists in India to provide visually impaired people to access any printed document or softcopies available on computer. Here, they have used and image sensor to take the image. Through image processing techniques, text has been extracted. To make the hardware device, they have used microcontrollers just as several other researchers have used. And also for the propagation of the Braille character, solenoid actuators are assembled. Another major factor highlighted in this research is that the assembling of the Braille dots has to be compact so as to meet the standards of the Braille when denoting the size of a Braille character.

A Literary Braille Language Translator to Spanish Text.

A set of scientists in Spain has thought of developing a Literary Braille Language Translator to Spanish Text. In this project, they have done in in a series of steps to get the final outcome. First the character recognition has been done to the Braille character image. Then the separation of information contained in each Braille cell were made in order to make the comparison with a database already established. After having done this comparison, the text contained in the image is exported using a graphical user interface as the next stage in the project. This has allowed the person to see the transcript in .txt format. In this project they have they have obtained the efficiency results in 22 images of text Braille, the total characters contain in each image and the errors found by observations to calculate the percentage of efficiency. click below to read the abstract. https://ieeexplore.ieee.org/document/7778514/

Sinhalese Braille

                                Sinhalese Braille                     Sinhalese Braille  is one of the Bharati braille   alphabets. While it largely conforms to the letter values of other Bharati alphabets, it diverges in the values of the letters assigned toward the end of those alphabets. Alphabet           although sinhalese braille adopt from bharati braille. several letters   t oward the end of the Bharati alphabet (in the row of 'extra' letters) have been reassigned in Sinhalese. sinhala alphabet compare with ISO and braille character shown as fig. 1 and fig. 2.                                                     fig. 1 sinhalese braille   ...

The Functional requirements related to the proposed system

The functional requirements for a system describe what the system should do. These requirements depend on the type of device being developed, the expected users of the device, and the general approach taken by the organization when writing requirements. When expressed as user requirements, functional requirements are usually described in an abstract way that can be understood by system users. However, more specific functional system requirements describe the device functions, its inputs and outputs, exceptions, etc., in detail. For example, here are examples of functional requirements for the reading device in Sinhala language for visually impaired people through the braille system,  These requirements have a specific order to the priority, but for easy of explaining following order may bit different from the correct order. [1] Turn on the Braille character display [21] Turn the device off When user select this option, Braille character display is turns on and resets di...

Malayalam text to braille system with OCR and SVM

        Era of technology, the knowledge resources are at the finger tips, it make lives easy  but in the society there are various kind of people including differently able people, visually impaired people .Considering about visually impaired people they have only two sources of knowledge, they are  audio and Braille script. Braille is a tactile writing system, Braille education remains important for developing reading skills among blind and visually impaired people. Visually impaired people can read computer screens and other electronic supports with refreshable braille displays and there are portable braille note takers and computer that prints with a braille embosser for their use. Each Braille character made up of six raised dots that arranged in rectangular blocks called cells. The number and the arrangement of these dots are different one character from another, since there are various braille alphabets vary from language to language. Translating nor...

summary of the research papers related to the project idea

When conducting the surveys on the literature reviews regarding our project idea, we found several researches conducted by scientists of foreign countries. Through this article I summarize some of the articles that our group members found out regarding the project idea.  They have used different methods when developing the device to translate braille characters to texts or vice versa. And also the main purpose of the development process is the cost effectiveness of the product which can be easily used by visually impaired people.  A survey has conducted by the scientists Mr. Vrushabh S. Dharme and Mrs. S. P. Karmore regarding the same issue identified related to visually impaired people, to produce an English text to Braille conversion system. They have found that in producing the Braille Display, the most efficient hardware parts are using microcontrollers instead of using FPGAs. The reason is the cost-effectiveness of microcontrollers rather than using FPGA for larg...

Conversion of Gujarati Text into Braille

Image
              Conversion of Gujarati Text into Braille       When we consider The Gujarati text into Braille conversion. As very less literature is found in Gujarati language for visually impaired people, if the research is carried out in this field, it will increase the amount of literature for them.       Gujarati is also one of In Indian languages, there is no notion of upper case and lower case. Sometimes, two or more characters are combined to form compound character. There are huge character sets (vowels and consonants) in the Indian Languages also.       There are over 50 million people worldwide who use Gujarati for writing and speaking. So they want to braille system for visually impaired people who practiced to use Gujarati language. A character is conjunct, if two half consonants are joined. So, characters in Gujarati can be the combination of consonant, vowels and diacritics. Gujarati...
