Tiresias fonts: Difference between revisions

Revision as of 15:27, 8 October 2009

A GPL family of sans-serif fonts with the goal of improving legibility on information labels.

Description

Tiresias is a family of realist sans-serif typefaces that were designed for best legibility by people with impaired vision at the Scientific Research Unit of Royal National Institute of the Blind in London. The research basis of Tiresias Screenfont’s legibility claims have been called into question.

Tiresias is the font used in subtitles for digital terrestrial television (DVB-T) in the UK and the Sky Digital satellite service (DVB-S) targeting the UK and Ireland.

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)
Tiresias LPfont – for large-print publications
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 released under the GNU General Public License version 3.[1]

+  — Add as many lines as necessary in the preceding table. Be careful not to mix faces with different characteristics on the same line (for example if a font bundle includes a serif font with a regular and bold face, and a sans-serif font with regular, bold, italic and bold-italic faces, use two different lines).
+  — Use ✘s to indicate a common feature is present.

+◆ Requester and packager: list there the elements you know of that will impact packaging activity, such as licensing that needs clarifying, an upstream that uses a specific non-english language to communicate, broken or incomplete build scripts, etc.
+◆ Packager: take care of those items and remove them from the page once they've been dealt with.
