What is the Ubuntu accessibility for blind people?

  • 772

Are there specific configurations and packages that could help blind people to use Ubuntu?

Blind people do use computers, and Ubuntu should be accessible to everyone.

It would be interesting to have the testimony of a totally or partially blind person who uses Ubuntu sharing their experience.

(Using Ubuntu 16.04, but I'm open to other Linux distributions)

16.04

    "It's easy to think that an operating system is easy to use, but we often forget that the same OS needs to work for people who can't have the same experience as the rest of us."

    Ubuntu is one of the most used operating systems, and it stands to reason that it's also being used by all kinds of people. This is why Canonical needs to have a much better accessibility support, and they are now working towards this end. Read more..

    Here are some examples of Ubuntu and Linux community as a whole supporting people with Visual problems.

    Options in Default Ubuntu.

    Gnome-orca is installed by default on Ubuntu. The Shortcut to turn on/off this feature is by pressing Alt + Super + S. Or you can manually activate in Settings --> Universal Access --> Seeing. There you should see couple of useful settings like High Contrast, Large text, etc..

  2. The "Seeing" tab under the "Universal Access" program has settings to help the vision impaired.

    Full blindness is going to be difficult with Ubuntu, but it is possible to use it, primarily with the Screen Reader function.

    For partial blindness, settings like High Contrast and Large Text can also help in addition to the Screen Reader.

    There are more functions and settings in the different tabs in the Universal Access program that can help as well.

  3. Alt+Super+S turns orca on, but sometimes, on weird configuration, it is'nt working, in this case, ctrl+alt+t then sudo apt install orca. If orca crashes, it happens some times, open terminal and type the following command. orca -replace I hope this helps!
