Large-print
Large-print (also large-type or large-font) refers to the formatting of a book or other text document in which the typeface (or font) are considerably larger than usual to accommodate people who have low vision. Frequently the medium is also increased in size to accommodate the larger text. Special-needs libraries and many public libraries will stock large-print versions of books, along with versions written in Braille. The font size for large print is typically at least 18 points in size, equivalent to 24px for a web CSS font size. Different sizes are made to suit different visual needs, with a common rule of thumb to be at least twice the minimum acuity size. Publishing standards The American National Association for Visually Handicapped (NAVH) provides the NAVH Seal of Approval to commercial publishers in the US, for books that meet their large print standards. (Lighthouse International acquired NAVH in 2010.) The standards call for: * Maximum limits on size, thickness, an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |

Tiresias (typeface)
Tiresias is a family of TrueType sans-serif typefaces that were designed with the aim of legibility by people with impaired vision at the Scientific Research Unit of Royal National Institute of Blind People in London. The font was originally designed for the RNIB by Chris Sharville of Laker Sharville Design Associates who was working with John Gill at the time. The family includes * Tiresias Infofont – for information labels, optimized for maximum legibility at a distance of 30–100 cm. * Tiresias Keyfont – for labeling the tops of keys of keyboards, PIN pads, appliances, remote controls (features exaggerated punctuation marks, no descender on the J) * Tiresias LPfont – for large-print publications. A wedge-serif design. * Tiresias PCfont – for raster displays * Tiresias Screenfont – for television subtitling and on-screen user interfaces * Tiresias Signfont – a more open spacing for use on signs In late 2007, all Tiresias fonts except Tiresias Screenfont were ...

Legibility
Legibility is the ease with which a reader can decode symbols. In addition to written language, it can also refer to behaviour or architecture, for example. From the perspective of communication research, it can be described as a measure of the permeability of a communication channel. A large number of known factors can affect legibility. In everyday language, legibility is commonly used as a synonym for readability. In graphic design, however, legibility is often distinguished from readability. Readability is the ease with which a reader can follow and understand words, sentences and paragraphs. While legibility usually refers to the visual clarity of individual symbols, readability is more about their arrangement or even the choice of words. Legibility is a component of readability. The legibility of text is most often examined by controlled deterioration of viewing conditions and determination of threshold detection. Not all writing benefits from optimizing for legibility.

Accessible Publishing
Accessible publishing is an approach to publishing and book design whereby books and other texts are made available in alternative formats designed to aid or replace the reading process. It is particularly relevant for people who are blind, visually impaired or otherwise print disabled. Alternative formats that have been developed to aid different people to read include varieties of larger fonts, specialised fonts for certain kinds of reading disabilities, braille, e-books, and automated audiobooks and DAISY digital talking books. Accessible publishing has been made easier through developments in technology such as print on demand (POD), e-book readers, the XML structured data format, the EPUB3 format and the Internet. Aim The aim of accessible publishing is to make reading easier for those who have difficulties doing so. This group includes people who are blind or who have low vision, people with learning disabilities, and people who are learning a second language. Access ...

Font Size
In typography, the point is the smallest unit of measure. It is used for measuring font size, leading, and other items on a printed page. The size of the point has varied throughout printing's history. Since the 18th century, the size of a point has been between 0.18 and 0.4 millimeters. Following the advent of desktop publishing in the 1980s and 1990s, digital printing has largely supplanted the letterpress printing and has established the DTP point (DeskTop Publishing point) as the ''de facto'' standard. The DTP point is defined as of an international inch () and, as with earlier American point sizes, is considered to be of a pica. In metal type, the point size of the font describes the height of the metal body on which the typeface's characters were cast. In digital type, letters of a font are designed around an imaginary space called an '' em square''. When a point size of a font is specified, the font is scaled so that its em square has a side length of that ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Verdana
Verdana is a humanist sans-serif typeface designed by Matthew Carter for Microsoft Corporation, with hand-hinting done by Thomas Rickner, then at Monotype. Demand for such a typeface was recognized by Virginia Howlett of Microsoft's typography group and commissioned by Steve Ballmer. The name "Verdana" is derived from "verdant" (green) and "Ana" (the name of Howlett's eldest daughter). Bearing similarities to humanist sans-serif typefaces such as Frutiger, Verdana was designed to be readable at small sizes on the low-resolution computer screens of the period. Like many designs of this type, Verdana has a large x-height (tall lower-case characters), with wider proportions and looser letter-spacing than on print-orientated designs like Helvetica. The counters and apertures are wide, to keep strokes clearly separate from one another, and similarly shaped letters are designed to appear clearly different to increase legibility for body text. The bold weight is thicker than would ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Typeface
A typeface (or font family) is the design of lettering that can include variations in size, weight (e.g. bold), slope (e.g. italic), width (e.g. condensed), and so on. Each of these variations of the typeface is a font. There are thousands of different typefaces in existence, with new ones being developed constantly. The art and craft of designing typefaces is called ''type design''. Designers of typefaces are called ''type designers'' and are often employed by ''type foundries''. In desktop publishing, type designers are sometimes also called ''font developers'' or ''font designers''. Every typeface is a collection of glyphs, each of which represents an individual letter, number, punctuation mark, or other symbol. The same glyph may be used for characters from different scripts, e.g. Roman uppercase A looks the same as Cyrillic uppercase А and Greek uppercase alpha. There are typefaces tailored for special applications, such as cartography, astrology or mathematics. Te ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Antique Olive
Antique Olive is a humanist sans-serif typeface ("antique" being equivalent to sans-serif in French typographic conventions). Along the lines of Gill Sans, it was designed in the early 1960s by French typographer Roger Excoffon, an art director and former consultant to the Marseilles based Fonderie Olive. In addition to a basic weight, ''Antique Olive'' was produced in medium, condensed, wide, bold, condensed bold, extra bold (known as ''Antique Olive Compact''), and ultra bold (known as ''Nord''). The key shapes, especially the letter O, resemble an olive, which is one of the characteristics which make Excoffon's typefaces unique. It was used in the Sesame Street ending credits from 1978-1983. Lewis Blackwell later commented on the design, "An attempt to offer a more refined sans serif than presented by Helvetica and Univers, but it was too characterful and too late to be widely adopted outside France." The face was later made available in cold type and digital versions are n ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Font
In metal typesetting, a font is a particular size, weight and style of a typeface. Each font is a matched set of type, with a piece (a " sort") for each glyph. A typeface consists of a range of such fonts that shared an overall design. In modern usage, with the advent of computer fonts, the term "font" has come to be used as a synonym for "typeface", although a typical typeface (or "font family") consists of a number of fonts. For instance, the typeface " Bauer Bodoni" (sample shown here) includes fonts "Roman" (or "Regular"), " Bold" and ''" Italic"''; each of these exists in a variety of sizes. The term "font" is correctly applied to any one of these alone but may be seen used loosely to refer to the whole typeface. When used in computers, each style is in a separate digital "font file". In both traditional typesetting and modern usage, the word "font" refers to the delivery mechanism of the typeface. In traditional typesetting, the font would be made from metal or wood t ...
