There have been some discussions lately about pinky/ring finger combos, e.g. WAR, YOU.
I am thinking to add an additional factor to my layout analysis model to account for this.
Currently the model only considers same-finger bigams, so bigrams like YO or AR not recognised as being a bit more difficult. This is not purely related to thier positions on weaker fingers, because, for example AI is easier than AR, even though they are both pinky/ring combinations. The issue as I see it, is one of using pinky and ring in quick succession on the same hand.
However, I don't want to overcomplicate things, e.g. by considering trigrams or other long sequencies and trying to account of all sorts of possible easy/difficult combinations of fingers. Instead, I'd rather continue to rely on the base value score for each key, and then add on any penalties to reflect difficult bigrams.
Proposal could be as simple as: in addition to exising same-finger bigram penalties, introduce a new same-hand pinky-ring bigram penalty, say at 1.0.
I don't anticipate it would have a significant effect overall.
Any comments/suggestions before I implement?
