<title>ATK</title>

<p>La accesibilidad es el proceso de asegurarse de que su aplicación se puede usar por personas con alguna o varias discapacidades. Las discapacidades pueden ser de muchos tipos: visuales, movimientos descoordinados, impedimentos auditivos, impedimentos cognitivos y del lenguaje y desordenes de apoplejías. Muchas personas tienen algún tipo de discapacidad y hacer su aplicación accesible permitirá que más gente pueda usarla de forma efectiva.</p>

<p>GNOME provides support for accessibility devices using the ATK framework,
which stands for Accessibility Tool Kit.  This framework defines a set of
interfaces to which graphical interface components adhere.  This allows, for
instance, screen readers to read the text of an interface and interact with its
controls.  ATK support is built into GTK and the rest of the GNOME platform,
so any application using GTK will have reasonable accessibility support for
free.</p>

<p>ATK solves the problem of plugging many different kinds of widgets (text
entries, text areas, buttons, menus) with many different types of accessibility
technologies (screen readers, braille displays, sip-and-puff control devices).
Instead of writing N×M interfaces, from each widget to each accessibility
device, one just has to expose a widget through ATK's interfaces.
Accessibility devices will in turn use these interfaces to query accessible
widgets.  For example, an aural screen reader and a braille display will both
use a standard "get the text contents" interface in ATK for all widgets with
textual information.</p>

<p>Nonetheless, you should be aware of accessibility issues when
developing your applications.  Although GTK interfaces provide
reasonable accessibility by default, you can often improve how well
your program behaves with accessibility tools by providing additional
information to ATK.  If you develop custom widgets, you should ensure
that they expose their properties to ATK.  You should also avoid using
sound, graphics, or color as the sole means of conveying information
to the user; have redundant ways of providing this information instead of
relying on the user being able to perceive a particular medium.</p>

<p>El escritorio GNOME posee cierto número de herramientas de accesibilidad que permiten a los usuarios con discapacidades usar plenamente el escritorio y sus aplicaciones. Las aplicaciones que implementan completamente ATK serán capaces de trabajar con las herramientas de accesibilidad.Entre estas se incluyen un lector de pantalla, un magnificador de pantalla, un teclado en pantalla y <app>Dasher</app>, una innovadora herramienta de predicción de entrada de texto.</p>
