Free software and / or Ubuntu have always had one very good thing that many proprietary software have never had: free development. And this is important for altruistic projects such as adapting the new technologies to the most disadvantaged agents. A good example of these words is in Orca, a program of Free software that without intention of earning money, has achieved that thanks to the efforts of a few, many blind people can enjoy the new technologies, although not as we would like to all, but in an autonomous way.
Orca It is a software that allows us to expand the desktop as well as it is a great screen reader so that the user can have an idea of the menu or object that is active without having to see it, just by ear. What's more Orca allows us to interact with braille devices, so at a point, if we have any Braille device, we can choose if we want Orca read us the screen, send it to Braille device or both.
Although Orca is created under a Free Software license, it is one of the programs that are integrated with the gnome desk, so it is not only a consolidated program but also thoroughly tested and documented. Requirements that make Orca a program more than necessary in public equipment and systems that meet the standards of adaptability.
Orca is in the Gnome Project
Being integrated within Gnome, Orca It is available for all Gnu / Linux systems, not just Ubuntu, so the installation is very easy to do. In the case of Ubuntu, Orca It is installed by default, if it happens that we do not have it, it may not come installed by default in some flavor, we just have to go to the console and write:
sudo apt-get install orca
And with this the installation will begin. The only problem that I see Orca is that when we review the documentation, I do not see any documentation adapted to the blind, until recently there was audio guides for installation and configuration of this program, but currently the links to these audio guides are down. So I take advantage of the space to ask, if someone has or knows the link to an audio guide, comment on it in the post. Thus, we can all benefit better from this software, some for being able to handle Ubuntu, others for being able to have more companions in this great community.
