User friendly system for the visually impaired in learning Al-Quran

This study presents a method to enable the visually impaired Muslim to learn and read the Al-Quran using Braille Display with software help. The system reads the database which contains all verses of Al-Quran and user will need to select the verse and ayah to read. Besides that, this system can be used in a class to teach visually impaired students to learn Al-Quran. Every word or character typed by the instructor in the main Braille Panel will be transmitted to the sub Braille Panel that is connected to the main Braille Panel. The selected verse of Al-Quran and ayah will also generate an index before being transmitted to the Braille Panel. The index will be transmitted to the Braille Display for people to touch and read the display. A user friendly Graphical User Interface (GUI) will be used to fulfill the ergonomics for the visually impaired user's physical capabilities. Several approaches are used to design and implement the interface for the visually impaired like speech or sound output and Braille display. The Braille codes can be displayed using the Braille panel. The design interface and structure of the system for the visually impaired users in learning Al-Quran is presented

BrlAPI: Simple, Portable, Concurrent, Application-level Control of Braille Terminals

Screen readers can drive braille devices for allowing visually impaired users to access computer environments, by providing them the same information as sighted users. But in some cases, this view is not easy to use on a braille device. In such cases, it would be much more useful to let applications provide their own braille feedback, specially adapted to visually impaired users. Such applications would then need the ability to output braille ; however, allowing both screen readers and applications access a wide panel of braille devices is not a trivial task. We present an abstraction layer that applications may use to communicate with braille devices. They do not need to deal with the specificities of each device, but can do so if necessary. We show how several applications can communicate with one braille device concurrently, with BrlAPI making sensible choices about which application eventually gets access to the device. The description of a widely used implementation of BrlAPI is included

The Electronic Braille Type Machine Basically of Microcontroller ATmega16

Now, caring for blind is too fews. The public information or the same kind in braille font is rarely to find. It cause made of braille font with manual methode needs a long time, beside that the creator must to learn the motif of braille font. There are the printer of braille font, but the price is tooexpensive. This fact be principle of made the electronic braille type machine basically of microcontroller ATmega16 for easy made the general people to comunicate with the blind. Start of process to made this instrument is stake out and connect of hardware and next process is made of software. This instrument use keyboard as input and two motor stepper aslo a solenoid as output. The preparation of software for directed in microcontroller ATmega16 use C language and software CodeVision AVR as compiler. Finishing process is to downloading the software to microcontroller ATmega 16. The hardware is succesfull made use minimum system microcontroller ATmega16, That joined with other instrument. The software of electronic braille type machine basically of microcontroller ATmega16 is succesfull made use CodeVision AVR in one main program. This instrument read the data from input keyboard that press, to move motor stepper and or solenoid so that can to bring outside motif braille font the suitable knot of keyboard that press at a sheet of paper.

A robust braille recognition system

Braille is the most effective means of written communication between visually-impaired and sighted people. This paper describes a new system that recognizes Braille characters in scanned Braille document pages. Unlike most other approaches, an inexpensive flatbed scanner is used and the system requires minimal interaction with the user. A unique feature of this system is the use of context at different levels (from the pre-processing of the image through to the post-processing of the recognition results) to enhance robustness and, consequently, recognition results. Braille dots composing characters are identified on both single and double-sided documents of average quality with over 99% accuracy, while Braille characters are also correctly recognised in over 99% of documents of average quality (in both single and double-sided documents)

Aiding the Visually Impaired: Developing an efficient Braille Printer

With the large number of partially or completely visually impaired persons in society, their integration as productive, educated and capable members of society is hampered heavily by a pervasively high level of braille illiteracy. This problem is further compounded by the fact that braille printers are prohibitively expensive - generally starting from two thousand US dollars, beyond the reach of the common man. Over the period of a year, the authors have tried to develop a Braille printer which attempts to overcome the problems inherent in commercial printers. The purpose of this paper, therefore, is to introduce two prototypes - the first with an emphasis of cost-effectiveness, and the second prototype, which is more experimental and aims to eliminate several demerits of Braille printing. The first prototype has been constructed at a cost significantly less than the existing commercial braille printers. Both the prototypes of the device have been constructed, which will be shown.Comment: 6 pages.

An Arabic Optical Braille Recognition System

Technology has shown great promise in providing access to textual information for visually impaired people. Optical Braille Recognition (OBR) allows people with visual impairments to read volumes of typewritten documents with the help of flatbed scanners and OBR software. This project looks at developing a system to recognize an image of embossed Arabic Braille and then convert it to text. It particularly aims to build fully functional Optical Arabic Braille Recognition system. It has two main tasks, first is to recognize printed Braille cells, and second is to convert them to regular text. Converting Braille to text is not simply a one to one mapping, because one cell may represent one symbol (alphabet letter, digit, or special character), two or more symbols, or part of a symbol. Moreover, multiple cells may represent a single symbol
