The avatars available in Santos are all based on scans from actual humans (not estimated from a database). If he is able to provide the stature for each avatar, you could quickly evaluate how each avatar fits into the percentiles of relevant databases (i.e., NHANES, ANSUR II, etc.).
Whatever the original subject’s anthropometry and morphology were at the time of the body scan is what was used to create the Santos avatar. We do provide the ability to adjust anthropometry of any targeted avatar. If you select one of our avatars from the library, it is as if you’ve selected an actual person off the street. This approach was taken because of a report done by the Air Force Research Lab in the early 2000’s that argued that since there are no people who have the measurements of a 50th percentile male (for example), it is better to use actual case studies for design purposes. All of our funding partners agreed with this, and that is the approach we have always taken.
