For accessibility assistance, which of the following programs is an on-screen keyboard?
A
xkb
B
atkb
C
GOK
Correta
D
xOSK
Explicação Oficial / Explicações da Comunidade
The correct program is GOK (GNOME On-screen Keyboard). GOK is a dynamic on-screen keyboard designed for users with physical disabilities who cannot use a standard keyboard. It provides word completion, scanning, and other assistive features.
How it Works
GOK integrates with the GNOME desktop environment and the AT-SPI (Assistive Technology Service Provider Interface) to allow users to input text by clicking keys displayed on the screen. It supports multiple input methods, including direct selection, scanning, and switch access.
Why the Correct Value is Right
- GOK is specifically developed as an on-screen keyboard for accessibility. It is part of the GNOME Accessibility Project and is widely used in Linux distributions.
Why the Incorrect Values are Wrong
- xkb is the X Keyboard Extension, which manages keyboard layouts and key mappings. It is not an on-screen keyboard but a low-level configuration tool for physical keyboards.
- atkb is not a standard Linux accessibility program. It may be confused with ATK (Accessibility Toolkit), which is a library for accessibility support, not an on-screen keyboard.
- xOSK is not a standard program. While "OSK" stands for On-Screen Keyboard, xOSK is not a recognized package in major Linux distributions. The correct on-screen keyboard in X11 environments is often
xvkbdoronboard, not xOSK.
