Braille Technology
Braille technology is assistive technology which allows blind or visually impaired people to do common tasks such as writing, browsing the Internet, typing in Braille and printing in text, engaging in chat, downloading files, music, using electronic mail, burning music, and reading documents. It also allows blind or visually impaired students to complete all assignments in school as the rest of sighted classmates and allows them take courses online. It enables professionals to do their jobs and teachers to lecture using hardware and software applications. The advances of Braille technology are meaningful because blind people can access more texts, books and libraries and it also facilitates the printing of Braille texts. "Despite the Braille system's universal reach, the National Federation of the Blind estimates that only 10 percent of the vision-impaired are able to read Braille". Software Some of the software available currently: * Duxbury DBT, is a program that translate ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Assistive Technology
Assistive technology (AT) is a term for assistive, adaptive, and rehabilitative devices for Disability, people with disabilities and the elderly. Disabled people often have difficulty performing activities of daily living (ADLs) independently, or even with assistance. ADLs are self-care activities that include toileting, mobility (ambulation), eating, bathing, dressing, grooming, and personal device care. Assistive technology can ameliorate the effects of disabilities that limit the ability to perform ADLs. Assistive technology promotes greater independence by enabling people to perform tasks they were formerly unable to accomplish, or had great difficulty accomplishing, by providing enhancements to, or changing methods of interacting with, the technology needed to accomplish such tasks. For example, wheelchairs provide independent mobility for those who cannot walk, while assistive eating devices can enable people who cannot feed themselves to do so. Due to assistive technology, ...

Blindness
Visual impairment, also known as vision impairment, is a medical definition primarily measured based on an individual's better eye visual acuity; in the absence of treatment such as correctable eyewear, assistive devices, and medical treatment– visual impairment may cause the individual difficulties with normal daily tasks including reading and walking. Low vision is a functional definition of visual impairment that is chronic, uncorrectable with treatment or correctable lenses, and impacts daily living. As such low vision can be used as a disability metric and varies based on an individual's experience, environmental demands, accommodations, and access to services. The American Academy of Ophthalmology defines visual impairment as the best-corrected visual acuity of less than 20/40 in the better eye, and the World Health Organization defines it as a presenting acuity of less than 6/12 in the better eye. The term blindness is used for complete or nearly complete vision loss. In ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Braille
Braille (Pronounced: ) is a tactile writing system used by people who are visually impaired, including people who are blind, deafblind or who have low vision. It can be read either on embossed paper or by using refreshable braille displays that connect to computers and smartphone devices. Braille can be written using a slate and stylus, a braille writer, an electronic braille notetaker or with the use of a computer connected to a braille embosser. Braille is named after its creator, Louis Braille, a Frenchman who lost his sight as a result of a childhood accident. In 1824, at the age of fifteen, he developed the braille code based on the French alphabet as an improvement on night writing. He published his system, which subsequently included musical notation, in 1829. The second revision, published in 1837, was the first binary form of writing developed in the modern era. Braille characters are formed using a combination of six raised dots arranged in a 3 ×&n ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
National Federation Of The Blind
The National Federation of the Blind (NFB) is an organization of blind people in the United States. It is the oldest and largest organization led by blind people in the United States. Its national headquarters are in Baltimore, Maryland. Overview Anyone, blind or sighted, is permitted to join the NFB, but a majority of members in its local chapters, state affiliates, and nationwide divisions must be blind, as must its officers and board members at every level with exception of the National Organization of Parents of Blind Children. This structure is intended to ensure that the organization is run by blind people and reflects the collective views of its blind members, the NFB refers to itself as "the voice of the nation's blind." The philosophy of the organization is: The organization's former president, Kenneth Jernigan, said, "We who are blind are pretty much like you. We have our share of both geniuses and jerks, but most of us somewhere between, ordinary people living ordin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Braille Translator
A braille translator is a software program that translates a script into braille and sends it to a braille embosser, which produces a hard copy of the original print text. Only the ''script'' is transformed, not the ''language''. Description For the purposes of this article, the word "inkprint" means text prepared for reading by the eye, whether printed, displayed on a screen, or stored in a computer; "braille" means text prepared for reading by the finger, whether brailled, displayed on an electronic device, or stored in a computer. Braille translation software or embedded hardware converts inkprint into braille or braille into inkprint. Usually someone has inkprint in a word processor file or at an URL and wants braille. The braille could be sent to a braille embosser to produce physical braille or to an electronic notetaker. Another circumstance is that someone has braille in an electronic braille notetaker that they want to produced in inkprint to be shared with someone w ...

JAWS (screen Reader)
JAWS ("Job Access With Speech") is a computer screen reader program for Microsoft Windows that allows blind and visually impaired users to read the screen either with a text-to-speech output or by a refreshable Braille display. JAWS is produced by the Blind and Low Vision Group of Freedom Scientific. A May–June 2021 screen reader user survey by WebAIM, a web accessibility company, found JAWS to be the most popular screen reader worldwide; 53.7% of survey participants used it as a primary screen reader, while 70.0% of participants used it often. JAWS supports Windows 10 and Windows 11 along with all versions of Windows Server released since Windows Server 2016. There are two versions of the program: the ''Home'' edition for non-commercial use and the ''Professional'' edition for commercial environments. Before JAWS 16, the ''Home'' edition was called ''Standard'', and only worked on home Windows operating systems. A DOS version, sometimes also known as ''JDOS'', is f ...

Braille Display
A refreshable braille display or braille terminal is an electro-mechanical device for displaying braille characters, usually by means of round-tipped pins raised through holes in a flat surface. Visually impaired computer users who cannot use a standard computer monitor can use it to read text output. Deafblind computer users may also use refreshable braille displays. Speech synthesizers are also commonly used for the same task, and a blind user may switch between the two systems or use both at the same time depending on circumstances. Mechanical details The base of a refreshable braille display often integrates a pure braille keyboard. Similar to the Perkins Brailler, the input is performed by two sets of four keys on each side, while output is via a refreshable braille display consisting of a row of electro-mechanical character cells, each of which can raise or lower a combination of eight round-tipped pins. Other variants exist that use a conventional QWERTY keyboard for in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

NonVisual Desktop Access
NonVisual Desktop Access (NVDA) is a free and open-source, portable screen reader for Microsoft Windows. The project was started by Michael Curran in 2006. NVDA is programmed in Python. It currently works exclusively with accessibility APIs such as UI Automation, Microsoft Active Accessibility, IAccessible2 and the Java Access Bridge, rather than using specialized video drivers to "intercept" and interpret visual information. It is licensed under the GNU General Public License version 2. History Concerned by the high cost of commercial screen readers, In April 2006, Michael Curran began writing a Python-based screen reader with Microsoft SAPI as its speech engine. It provided support for Microsoft Windows 2000 onwards, and provided screen reading capabilities such as basic support for some third-party software and web browsing. Towards the end of 2006, Curran named his project Nonvisual Desktop Access (NVDA) and released version 0.5 the following year. Throughout 2008 and 20 ...

Open Source
Open source is source code that is made freely available for possible modification and redistribution. Products include permission to use the source code, design documents, or content of the product. The open-source model is a decentralized software development model that encourages open collaboration. A main principle of open-source software development is peer production, with products such as source code, blueprints, and documentation freely available to the public. The open-source movement in software began as a response to the limitations of proprietary code. The model is used for projects such as in open-source appropriate technology, and open-source drug discovery. Open source promotes universal access via an open-source or free license to a product's design or blueprint, and universal redistribution of that design or blueprint. Before the phrase ''open source'' became widely adopted, developers and producers have used a variety of other terms. ''Open source'' ga ...

Braille Embosser
A braille embosser is an impact printer that renders text as tactile braille cells. Using braille translation software, a document or digital text can be embossed with relative ease. This makes braille production efficient and cost-effective. Braille translation software may be free and open-sourced or paid. Blind users tend to call other printers "ink printers," to distinguish them from their braille counterparts. This is often the case regardless of the type of printer being discussed (e.g., thermal printers being called "ink printers" even though they use no ink). As with ink printers and presses, embossers range from those intended for consumers to those used by large publishers. The price of embossers increase with the volume of braille it produces . Types The fastest industrial braille embosser is probably the $92,000 Belgian-made NV Interpoint 55, first produced in 1991, which uses a separate air compressor to drive the embossing head and can output up to 800 brai ...
