Re: [orca-list] Magnifier



You are correct. It is really too bad, since it is a fairly basic and important feature for a magnifier to have and given the large number of persons with low vision around the world.

In fact, I am considering adding this feature to the list of items we would fund if my next proposal is successful with foundations.

The latest third-party estimate of the total number of Gnome users around the world is over 14 million. If we make the fairly safe assumption that the number of actual and potential users of Gnome that have low vision is similar to the number observed in the general population (based on a 2011 WHO study), we quickly find that this feature can help a potential population of about 504 thousand persons.

Assuming that this improvement on Gnome will cost 5 thousand Dollars or less to implement, the cost of helping 504,000 users with magnification is less than one cent per person. What foundation would say no to that return on investment, assuming they understand how FOSS works.

BTW, if anybody wants to suggest foundations for me to get in touch with, please do. I can be reached at fernando botelho f123 org

    Hi,

    The problem with magnification with the free systems I know about, is
    that they do not do cursor tracking. For this reason F123 funded
    improvements to the eZoom plugin for Compiz Fusion.

    Thanks to Alejandro Leiva, the developer with whom we have been working
    on this initiative, there is an improved version available for testing.

    We are hopeful it will soon be available for use at the upstream
    version
    of eZoom, but for those who know how to use GIT repositories etc, here
    is the info:

    Alejandro's GIT repository can be found at:
    https://github.com/gloob/compiz-accessibility-plugin

    You can also find Alejandro's version of eZoom at this URL:
    https://github.com/gloob/gloob-Ezoom-fork

    To give Alejandro feedback, please contact him at this e-mail address:
    gloob litio org

    Please note that Gnome 3 does not use Compiz Fusion, and for that
    reason
    cannot use this plugin. It should be fine for Gnome Fallback and Unity
    3D, but I have personally not tried it yet, since I am blind.

    Best wishes,

    Fernando
