- Hi all!
-
- I've worked with a DataGlove for some time now (a base model: 10
- sensors), and I'd like to know if anyone else who has worked with it
- has come up with a good solution of a problem I found.
-
- I'd like to have a good wire-frame model of the hand (but the same
- problem should apply to solid modeled ones). By wire frame HERE I mean
- that each finger is just a serie of 3 segments, not "strips".
-
- The problem I found is the THUMB: since the DataGlove can't detect all
- movements of the first joint of the thumb (i.e. the one which links
- the finger and the hand), without additional sensors, I was wondering
- around WHICH axis the thumb should twist about: it surely isn't one of
- the coordinate ones (X,Y,Z), and I've come out with a strange one,
- empirically (sp?) found with trial and error. But it still doesn't
- satisfy me. Infact if I make an OK posture, touching thumb and index,
- the on-screen hand doesn't do the same, having always some
- mis-alignment (sp?) between the two fingers. It surely depends on the
- fact that I LOCKED the thumb movement on the WRONG plane.
-
- Has someone else found a better solution? Reply directly to me, and
- I'll summarize if there's enough interest.
-
- Thanks very much and HAPPY NEW YEAR to all the Net!
