#MOVING MAN
Sus,
if you get Puppeteer by Schreiber Instruments you can import Biovision motion
files to the puppets – these are optically captured skeletal motions of actual
humans. Viewpoint sells a whole bunch of such motion files. If you are
well-heeled you could send your performers up to Biovision and have them go
through their performances which will then be turned into motion files for
import to Puppeteer. If they are not suitable you can always create your own
using Puppeteer's animation tools.
