First off, I'm usually more of a lurker; not one to register and comment on forums, and so probably not well suited as an alpha tester. However in this case, I felt compelled to register and post before this topic gets backburnered and filed away due to lack of feedback.
I'm on a PC with a 23" monitor running 1920x1080 resolution and no vision problems, and I have some UI suggestions / requests within the scope of an alternate UI.
a) In fullscreen with 18/Terminus I find it OK, but the bright green on black background does get hard on the eyes after a while. Might it be possible to add support for menu & UI themes/color schemes? For example, I could read text on this forum's gray theme all day.
2) I would love to see a larger font & tile size in the future. Something closer to DCSS font & tile sizes would be amazing.
I realize you would lose some range of vision and it would affect some of the scanning parts, but i wonder if there isn't an alternative solution than just neutering their function to suit larger tiles.
- Maybe a toggle-able mini map?
- or when you hold a key to pan around the map it might zoom out while you're holding it?
- What about binding the numpad +/- keys to a zoom function, allowing you to zoom in/out at will. If something enters your vision outside of your zoom level, show an icon and the edge of the map window -- prompting you to zoom out and see what's there.
I made a couple mockups and uploaded them here:

Even if I move my taskbar to the side, i still lose enough of the screen that I can't see the inventory hotkeys on the bottom edge of the screen (t\m\i). It may be a minor annoyance but it is one nonetheless.
This might be solved by reducing the vertical tile count by a few (as you mentioned elsewhere as possible). Alternatively, an option for a borderless window? I'm not sure how that might affect anything.
To close, I think Cogmind is a fun and unique take on a unique genre, and some user experience improvements in the above areas could go a long way to broaden its appeal; not only for people with some visual impairment or a smaller screen, but also everyone else.
