Actually we are here at the EEE dept working on a 'Dataglove', And I
have defined the differents movment possible with our Finguers
(including the Thumb ) and the Wrist. But I didnt find any literature
in the same topic except book of anatomy and human physiology, does
anybody work on the 'Glove'. So we can check if my work is correct.

Movments I defined:

For all the finguer (except the Thumb):
Flexion through the 3 articulations
rotation through the 1st articulation
The thumb :
Flexion through the 3 articulation
Rotation in 2 planes
Wrist :
Flexion
Rotation through two planes


I have defined also three kind of Control points in MyHand
The ControlPoints (we need their coordinates )
The Flexion points (For hand gesture)
The reotation/flexion points ( For hand gesture)
and the HotPoints  ( For Hand interfacing with Virtuals Objects)

Here's MyHand:



                            1    2
        @-------------------*----0----0---#
        |                   |
        |                   *-------0-----0---#
        *        #          |
        |                   *-------0------0---#
        |                   |
        *-------------------*------0-----0---#
         \
          0
            \               (The structure of MyHand)
                0            @ ControlPoint only
                  \          * Flexion and rotation
                    #        0 Flexion only
                             # HotPoints



(is'n it nice ?? )

   So does anybody work on this topic as we may share what we know
   I forgot to tell you that the goal is to drive it with an
interface we're building it here at the EEE dept of the Sheffield
University.
Before, should you notice that LLittlePt1 is located at 1 and
LLittlePt2 is located as 2, and the following is a bout a flexion.

    The other goal is to try to use the electrical signals from the
muscules (when they are activated) drive the hand (this is a second
experience for a long term work ) . Says for example if the muscle in
the section LLittlePt1-LLittlePt2 is activated, that's means we have
to apply to all the finguer at the point LLittlePt1 a rotation (says
about 5 degree each time (we've to train our hand to this kind of
things), do you see where I am going??? .

So, all comments and help is welcome.

Virtualy,
Bens.

I will send later another e-mail about an application to
Architecture,  I've call Project ICARUS (Interface for Computer
aided ARchitectural design Using virtual Spacework)
Which is my project here at the School of architectural studies of
the University of Sheffield

ps: For more info, just send me your e-mail address.
