NJ5, we don't know if he is speaking about the size of the SDK or the actual run time size of the dlls.

And handling hidden body parts locations programmatically is no trivial task.

That's true, but the quote made me think it was the recognition software:

The result was a 50-megabyte software package that can recognise 31 different body parts in any video frame.

I maintain that calculating where the hand is from the arm's angle and length is trivial. High school maths, at most?

Oh, and 50 MB? If it occupies that in RAM, that's quite a lot, about 20% of RAM gone.

 

50MB is less than 10% of the 360's 512MB of RAM

Around half of the RAM is used for graphical memory (depending on the game, that's why I said "about").

 

Unlike the PS3, the memory on the 360 is integrated, so one can't say that half the RAM is used for graphical memory.  How much is used depends on how developers allocate it.  With the PS3, that would be true though, but it isn't so with the 360.
