3 Definitions and abbreviations
3.1 Definitions
For the purposes of the present document, the tems and definitions given in FTSI Eli 201 013 [i.41 and the following apply:
accessibility: extent to which products, systems, services. cnvironmcnts and facilities can be used by people from a
population with the widest range of characteristics and capabilities, to achieve a specified goal in a specified context of
use (from ISO 26X00 11.181)
NOTE 1: Context of use includes direct use or use supported by assistivc technologies.
NOTE 2: The context in which the IC!’ is used may affect its overall accessibility. This context could include other products and services with which the ICT may interact.
assistise technology: hardware or software added to or connected to a system that increases accessibility for an individual
NOTE I: Examples are Braille displays. screen readers, screen magnification software and eye tracking devices that are added to the ICT.
NOTE 2: Where ICT does not support directly connected assistivc technology, but which can bc operated by a system connected over a network or other remote connection, such a separate system (with any included assistive technology) can also be considered assistive technology.
audio description: additional audible narrative, interleaved with the dialogue, which describes the significant aspects of the visual content of audio-visual media that cannot be understood from the main soundtrack alone
NOTE: This is also variously described using tcnns such as “video description” or variants such as “descriptive narration”.
authoring tool: software that can be used to create or modify content
NOTE 1: An authoring tool may be used by a single user or multiple users working collaboratively.
NOTE 2: An authoring tool may be a single stand-alone application or be comprised of collections of applications.
NOTE 3: An authoring tool may produce content that is intended for further modification or for use by end-users.
caption: synchronized visual and/or text alternative for both speech and non-speech audio information needed to understand the media content (after WUAG 2.0 14])
NOTE: This is also variously described using terms such as “subtitles” or variants such as “subtitles for thc dcaf and hard-of-hearing”.
closed functionality: functionality that is limited by characteristics that prevent a user from attaching. installing or using assistivc tcchnology
content: information and sensory experience to be communicated to the user by means of software, including code or markup that defines the content’s structure. presentation. and interactions (after WCAG2ICT [i.261)
NOTE: Content occurs in three places: web pages. documents and software. When content occurs in a web page or a document, a user agent is needed in order to communicate the content’s intiwmation and SenSOry experience to the user. When content occurs in software, a separate user agent is not needed in order to communicate the content’s information and sensory experience to the user – the software itself performs that function.
context of use: users, tasks, equipment (hardware. sotlware and materials), and the physical and social environments in which a product is used (from ISO 9241-Il [i.lSj)
document: logically distinct assembly of content (such as a file, set of files, or streamed media) that functions as a
single entity rather than a collection, that is not part of software and that does not include its own user agent. (after
WCAG2ICT (i.26j)
NOTE I: A document always requires a user agent to present its content to the user.
NOTE 2: Letters, e-mail messages. spreadsheets, books. pictures, presentations. and movies are examples of documents.
NOTE 3: Software configuration and storage files such as databases and virus definitions, as well as computer instruction files such as source code, batch/script tiles, and firmware, are examples of files that function as part of software and thus are not examples of documents. If and where software retrieves “information and sensory experience to be communicated to the user” from such files, it is just another part of the content that occurs in software and is covered by WCAG2ICT like any other parts of the software. Where such filcs contain one or more embedded documents, the embedded documents remain documents under this definition.
NOTE 4: A collection of files zipped together into an archive, stored within a single virtual hard drive file, or stored in a single encrypted tile system file, do not constitute a single document when so collected together. The software that archivcs/cncrypts those files or manages the contents of the virtual hard drive does not function as a user agent for the indhidually collected files in that collection because that software is not providing a fully functioning presentation of that content.
NOTE 5: Anything that can present its own content without involving a user agent. such as a self-playing book, is not a document but is software.AS EN 301549 pdf download.
