Yes it's amazing how long these ideas have been around. I remember Open

a good job of demo'ing the concept with concrete examples, although I
particularly like his point about supporting "ideas". Maybe this area is
getting reborn for the touchy-feely tablet age :-)

Possibly combined with code to detect context (eg, what is selected)
bring up an appropriate manipulator and trigger post-change actions,
avoiding actual typing where possible. The time-series feature of the
game demo looks more tricky. Guess it's a case of carefully picking your
battles since, as some people are quick to point out, this type of
interaction might not be practical in some cases.
