So you say something like to achieve little variations of notes ("vibrato" alike) depending on the key/finger movement, isn't it? I think there is something like that in really expensive keyboards/controllers, but not sure.

three forms of aftertouch they mention don't seem to include my idea of
directional movement while holding the key down.
But an array of Trackpoints might be interesting as a control input, too.
