Tails e il desktop GNOME includono tecnologie di assistenza per aiutare utenti con disabilità di vario tipo e necessità specifiche, e per interagire con comuni dispositivi di assistenza.

Accessibility menu

You can activate several assistive technologies, like a screen reader or large text, from the accessibility menu in the top bar, the 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 ().

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

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)
