The Raspberry PI microcomputer developed by the Charity Organization of the Raspberry PI Foundory is also the "Raspberry Part" after the launch of the world, whether it is a developer, or some DIY players, the microcomputer with only credit card size Holds a lot of interest. Indeed, this cheap and compact microcomputer contains a lot of possibilities.
In India, the visual impairment has nearly 8 million. In China, this figure is an amazing 17.3 million, accounting for 18% of the total number of blind people. Blind people not only experience more difficulties in life, but more obstacles in learning are much more than ordinary people. For example, there is a media report today. my country has a blind student to participate in the ordinary college entrance examination, which is helpless. It is more reality. It has experienced blind isolation education, and how easy it is integrated into ordinary college education.
Although there is a Braille Braille that is prepared for blind, Braille book costs will be higher, not to say that Braille displays, the Braille display of $ 4,000 prices cannot be accepted by the public. The blind people involved many aspects, and the efforts of the whole society, a team from India Bits Pilani University is working to solve one of the rings and is committed to providing the blind people with a Braille display, depending on the hardware foundation. Raspberry.
The Braille Braille Braille inventive in the Louis Braille is also a binary text, expressed text information by the projections (ON) and the following (OFF) in the dot matrix:
BITS Pilani University Computer Science Professional Student Sanskriti Dawle and Aman Srivastava realized that BRAILLE Braille Forms with Compact with Computer Principles It is easy to use a new Braille display with a barefriend display, but need 6 points Hardware design requirements are also not high. The development of speech recognition technology also makes the blind entry makes it easy, so they started this project called Project Mudra. The Braille display in the Project Mudra project has two modes. One is voice input, and the tactile text output, the second is the program input, the auditory tactile text output.
In the end, this team's research and development results are the following very simple devices, Dawler and Srivastav called Dicta-Teacher, and the entire architecture is primarily a Raspberry Piece, a Braille Ethics and some Python programs.
As can be seen from the appearance, it can achieve the function of the 4,000-dollar price of the Braille display, but this Dicta-Teacher cost-driven Dicta-Teacher cost is only $ 150, considering the higher Type B Raspberry Party on Jingdong. For only 299 yuan, I want to have been working hard by our Shenzhen manufacturers, the price of such equipment will be lower.
Because of the difficulty of education, in India, the illiterate rate of blind is very high, and the illiteracy rate in the United States is only 10%, and China's data is still unknown, but there is news that the special set of special isolation education systems, the final way, Most Chinese blind students are still massage, not cultural courses.
This situation is also one of the power of Sanskriti Dawle and Aman Srivastava to make cheap Braille Dicta-Teacher. They want to use Dicta-Teacher to improve the literacy rate of the blind people in India and developing countries, but this equipment will also help cultivate blind people. teacher. At present, they have been looking for non-profit partners, which will also become a reality of Project Mudra in prototypes, and ultimately achieve large-scale production.
