Info

Discussion• No synthetic human representatives, not ahuman figure poser; designs based onpopulation data and selected individuals• A population can be viewed in reference toa workstation layout allowing for rapidprototyping and accommodation ofanthropometric differences
Future Work• Allow view to switch from third-person view toassume a particular subject’s view (first-personmode)• Allow for the ability to save selected sceneelements and workstation configurations• Provide filtering based on demographic data• Add a joint-center model to facilitate posing of thelandmark and scan data
