Tails et le bureau GNOME incluent des technologies d'assistance pour aider les personnes avec divers handicaps et ayant des besoins spécifiques et pour interagir avec des périphériques d'assistance courants.

Accessibility menu

You can activate several assistive technologies, like a screen reader or large text, from the accessibility menu in the top bar, the accessiblity menu icon that looks like a person.

Accessibility menu with the following options, all disabled
by default: High Contrast, Zoom, Large Text, Screen Reader, Screen Keyboard,
Visual Alters, Sticky Keys, Slow Keys, Bounce Keys, and Mouse Keys

These technologies are documented in more details in GNOME Help: Accessibility.

Screen keyboard

If you prefer a pointing device over the keyboard, turn on the Screen Keyboard from the accessibility menu (accessiblity menu).

You can also use the screen keyboard to protect against hardware keyloggers by avoiding to use the actual keyboard.

If a keylogger has been physically installed on the computer, your passwords, personal information, and other data typed on the keyboard could be stored and accessed by someone else, even if you are using Tails.

For an example, see KeeLog: KeyGrabber forensic keylogger getting started.

Keyloggers are more likely on public computers, in internet cafés or libraries, and on desktop computers, where a device is easier to hide.

Reducing risks when using untrusted computers

The screen keyboard doesn't work in a Root Terminal. (#18061)

Instead, open a Terminal and execute the following command to log in as root:

sudo -i

The screen keyboard doesn't work in Kleopatra, Electrum, and KeePassXC. (#19695)

Instead, you can use the screen keyboard in the Text Editor first, then cut and paste into one of these applications.
