Re: On Braille and Linux

Smart phones use touchscreen braille input to make typing faster. 
Devin Prater. This attempts to bring this to Linux smart phones and such like that. I'd work on getting Orca working on it first before working on a text input method, but that's just me lol.

AIUI, you mean using a touch screen or touch pad to type Braille? I'm
not aware of anything like that.

There are various ways to do that. If your output is really keypresses
you can emulate a keyboard thanks to Linux' uinput. If your output is
rather text, you can use atspi's atspi_generate_keyboard_event. You can
also rather implement an ibus module.

I'd say start with determining what the user needs are precisely, before
looking at the technical details.
