bReader is my final year project which helps blind persons to read from anywhere. It is an embedded application and consists of java and Arduino code.
First of all you can get the overview of project by the given presentation:
The devices related to Braille are very expensive and the blind persons usually cannot afford. Technology has made available other aids for blind people, including talking calculators, speech-time compressors, computer terminals with speech output, Braille printers, paperless Braille computer terminals. But these devices are very costly to purchase.
Braille is a system of touch reading and writing for blind persons in which raised dots represent the letters of the alphabet. Braille is read by moving the hands from left to right along each line. Both hands are usually involved in reading process and reading is generally done by the index finger. The average reading speed is 125 words per minute. There are two levels in Braille language.
- Level 1
- Level 2
In level 1, Blind persons read the text character by character. In level 2, there are short hands in Braille language. We worked on level 1 Braille language.
Following figure shows the Braille language:
Blind persons first learn from the sixer like a Lego game. Figure shows the sixer for blinds:
First, the blind person learns to write on four liner as given below:
Then they move to the slate. They put the paper inside the slate and write with stylus as shown in figure:
The bReader is designed to help the visually impaired persons to read books. Books which are available for a blind person are expensive, so our embedded application gives assess to every blind person to read books easily and gain knowledge. Our application will facilitate the blind persons to read any text with the help of sound and braille device which will get as per given scanned text. If our application embedded on pen then it will be cheap relatively compared to present solutions and every person can buy it.
bReader has following features:
- Blind can click the picture
- Application scans the picture
- Extract text from picture
- Embossed the text character by character on braille device
- Give audio of the text
