Hi All,
I want to capture all keyboard input, in order to detect chords that
are pressed. This is for a project, where I hope to be able to
develop a Braille input method for Mac OS X.
One method of doing this would be to monitor both the keydown and
keyup events. Keep track of the keydown events, then when a key is
released, map the keys that were pressed to their braille equivalents,
then ignore the remaining key up events, then wait for key down
events, and repeat as necessary.
You will of course need to have some way of distinguishing between
grade 1 and grade 2 input though, since you'd obviously want to map
those inputs separately. Perhaps have a toggle mode, and if you plan
to support nemeth, or the new proposed standard for the uniform
braille code, you'd of course need yet another input mapping.
Simple enough on the surface, but as always, the devil is in the
details.
