The hyperhuman controller !
From the strictly physical point of view the dimensionality of
control possible for human beings could easily exceed 40 degrees
of freedom (Pressing 1990)
If we only consider articulations, one could easily count 3
degrees of freedom for each hand and foot, 3 additional ones
for each hand finger, 8 more for arms (elbows+shoulders) and
legs, 2 for the head, plus at least 1 more for breath pressure,
which gives a total of 53! [(3x4) + (3x10) + 8 + 2 + 1 = 53].
And that without taking into account other possible
physiological controllable parameters such as muscle tension
(e.g. Tanaka 2000), face expression (e.g. Lyons et al. 2003),
eye-tracking (e.g. Hornof & Sato 2004), or the absolute position
of the whole body in space (3 more parameters)
But this is much more than any human can handle!
