Natal plots 48 different points on a person's body, such as hands, feet and elbows, to create a wire-frame virtual manikin that mimics a person's movements.

do we know where those 48 points are located?  A lot of people talked up the possibilities of natal however, everyone seems to igore the part that natal doesn't track every part of your body (as least as far as information provided to the 360 is concerned).  I'd like to know how well natal tracks your hands,...will it track your individual fingers (22 points by my count) or just the hand location (2 points, left and right)?

Just curious, where did you hear the bolded?

I had not heard anything like that, but quite the opposite, that it DOES track every part of your body (via the wireframe mapping of specific points).

I think you are confused at what I meant.  It does track everypart of your body as far as head to toe is concerned...that doesn't mean it tracks every part of your body.  there are 38 joints in your fingers alone - since we know that your body is reduced to a wireframe of 48 points is a pretty safe assumption that natal will not track all 38 finger joints. 

it is basically a resolution issue, when you reduce a humans image down to just 48 points a lot of the finer details are lost which in turn limits what you can do with natal.  I remember someone getting all excited for a dragon ball (?!? or some other franchise i couldn't care less about) where a bunch of magic spells are cast by making specific hand guestures.  this person was all excited about a natal game that would allow for 1:1 capture of those hand guestures to cast their respective spells.  I don't think that is possible with the level of resolution this 1st gen natal will be able to caputure.

I actually count 30 joints in my fingers and maybe 34 if you count the wrist. But lets assume that 38 is the number in the fingers. So we need 2 for wrists, 2 for elbows, 2 for shoulders, 1 for neck(maybe actually the chin) 2 for knees, 2 for ankles, and 2 for the waist movement. So we're at 51 total. Not too far off, really.
