Find out how braille fonts are used on a computer.
On screen a braille font is used to indicate where braille dots or characters would appear in a document when later embossed. The fonts display as black filled dots simulating where the raised dots would be.
To enable braille dots to be viewed on a computer screen, an appropriate braille font needs to be installed. If you already have braille software on your computer, it may already have a braille font installed. To find out if you have a braille font installed, check if a braille font is listed in the font folder of your computer. If you don't have a braille font installed it will have to be downloaded separately.
For a braille font to be used effectively, it must be produced through braille translation software or by a professional braille transcriber, who understands the braille rules to convert the print text or proofread the final braille.
Beware of simply selecting print text on the computer and converting the print font to a braille font - this will not always produce correct braille, especially if you are producing contracted (Grade 2) braille or numbers.
There are many braille fonts which are available on the internet, some of which are free. Some fonts have been created for a specific purpose, however many are similar in design.
Simulated braille fonts show black filled dots where an embossed braille dot would be, along with a small shadow dot indicating where there is a missing dot. Simulated braille fonts cannot be used to create embossed braille, but are useful for displaying a braille font on screen in print and indicating where braille dots are placed.
Raised braille can be re-produced on swell paper, for example, to create labels to accompany tactile diagrams.
The black braille dots are ink printed onto the paper and raised by a heat fuser to create raised braille that can be felt tactually. Duxbury Systems Inc have created a swell braille font, which produces dots smaller than standard braille fonts, to account for the black dots swelling and become bigger when heated.
By using the swell braille font for tactile diagrams, the resulting dots are similar in size to standard embossed braille.
By using design software to create images, text can be converted to braille easily. As with a standard braille font, selecting and changing the font will not produce correct braille. It is possible to create the braille in a translation programme and copy and paste it into a design programme, and have a professional proofread the work.
