Without any surrounding reference points, they are indeed exactly the same. Reading individual single characters where vertical spacing is your only key, with no reference, or even with some, especially the single dot versions, could be troublesome. Also uncommon (except in programming - but I think of this as more a novel way to read prose than code) Also - standalone letters tend to be capitalized - and those have a reference bar above them... so it's not all bad. Still - good point. Learn braille,good idea. I'd go with learn ASL (sign?) as another suggestion too.... though this dotsie thing is definitely thought provoking (on the reading side - not the chording/typing side - that's pointless)
