Blind and visually impaired people (VIP) face many challenges in writing as they usually use traditional tools such as Slate and Stylus or expensive typewriters as Perkins Brailler, often causing accessibility and affordability issues. This article introduces a novel portable, cost-effective device that helps VIP how to write by utilizing a deep-learning model to detect a Braille cell. Using deep learning instead of electrical circuits can reduce costs and enable a mobile app to act as a virtual teacher for blind users. The app could suggest sentences for the user to write and check their work

The Braille system has been used by the visually impaired for reading and writing. Due to limited availability of the Braille text books an efficient usage of the books becomes a necessity. This paper proposes a method to convert a scanned Braille document to text which can be read out to many through the computer. The Braille documents are pre-processed to enhance the dots and reduce the noise. The Braille cells are segmented and the dots from each cell is extracted and converted in to a number sequence. These are mapped to the appropriate alphabets of the language. The Braille cell has a sta

A cost-effective and portable Braille printer with low noise is designed in this study. To reach this goal, the compressive printing concept is used and the Braille typesetting, the signal transmission interface module, the signal control module, and the Braille printing cell are designed and integrated. To increase the portability, the Braille printer is designed to use A4 size paper and each page can print at most twenty-four rows and twenty-seven Braille characters in each row. The typesetting of the printing page is designed to contain twenty-seven side-by-side Braille printing cells and e

Braille is the language used by visually impaired persons. Braille language comprises of collection of Braille cells which are embossed on a metal plate. Maintaining these bulky metal plates and distributing them to other parts of the world is a challenging task. This paper proposes a new technique of translating the Braille Cells embossed on plate to a natural language English character which can be easily distributed over network to make it globally accessible. Initially Braille documents are scanned, and preprocessing techniques like adaptive histogram and Laplacian filters are applied to a

Braille Display is a device which helps the visually impaired to read a text file in Braille format and as well receive an audio output of the text file. It gives an option to the user whether to receive output in terms of braille or audio. Braille is a tactile writing language of raised dots using which blinds and visually impaired people read and write through touch. The pattern of raised dots can be read with the fingers by blinds. The number and arrangement of these dots forms alphabets, numbers and special characters. The braille output in Braille display is observed in Braille text poppe

Braille codes are letters that are known by blind people to be able to obtain information through books including the Qur'an. The availability of media to learn to read the Qur'an in Braille code for blind people is very limited. In addition, the availability of teachers of the Koran for the blind is very limited because not many people can see normally who understands the Qur'anic letters in Braille code, so it is necessary to design and implement an Iqra Electronic Braille device to facilitate the reading process. the Qur'an in Braille code for blind people.

Les aspects statique et dynamique du comportement du bistable ont été analysés de manière détaillée. Le modèle cinématique exploité est le modèle Elastica extensible. La partie statique a été consacrée à l'étude des diagrammes de bifurcation pour trois types d'actionnements : force ponctuelle, éléments piézoélectriques et forces de Laplace. Pour chacune de ces technologies, une procédure d'optimisation a été mise en œuvre. À la fin de la partie st

Braille, recently, has come to be written for the instructions of the elevators and the public place for blind people. However, only about 10% of people who are blind can read Braille. This paper describes a Braille reader system using a cellular phone embedded camera for people who are blind. The system extracts images of Braille dots from a photo taken by the phone camera according to Braille dot features using image-processing methods. The Braille dot features are the size and shape of areas extracted in the photo. Then, the system detects Braille cells by grouping the extracted images of d

Many existing refreshable Braille display technologies are costly or lack robust performance. A process has been developed to fabricate consistent and reliable pneumatic balloon actuators at low material cost, using a novel manufacturing process. This technique has been adapted for use in refreshable Braille displays that feature low power consumption, ease of manufacture and small form factor. A prototype refreshable cell, conforming to American Braille standards, was developed and tested. The cell was fabricated from molded PDMS to form balloon actuators with a spin-coated silicone film, and
