EE Times (Issue 712, dtd 28 September,1992) has interesting article on
a Toshiba "glove" interface and algorithm.  The glove uses different
colored balls which are attached to the glove.  Movement of the glove
is monitored by an external video camera with an interface to a
Sparc-based workstation.  The workstation is equipped with 16 Motorola
68030 microprocessors, each of which tracks a ball and its movements.
The article cites that the breakthrough is in a new algorithm which
"quickly" calculates a set of simultaneous eqns.  to resolve movement
of the glove (balls).  The key is that the equations are calculated
using planes instead of points, therefore the algorithm can respond
more precisely to 3-D movements.

Has anyone heard of similar devices (e.g. alternates to the power
glove)?  It appears that this (the ball-TV-algorithm) method would be
easier to implement (given the algorithm) than a power glove
interface?  Any comments?
