| IN this section, we list our
major technical contributions in the various areas. In many cases, we feel that
these result have become possible only because of our multi-disciplinary approach to
research. A. Large
degree of freedom accurate modeling of the human musculoskeletal system. Using the
Denavit-Hartneberg method, typically used in the field of robotics, we have been able to
develop a spophisticated model of the human body.
B. Real-time environment. Unlike the
current state of the technology, Santos lives in a real-time environment. You ask him to
do something, and he does it right away...no waiting...no manipulation of the
mannequin...this, we believe, is a revolutionary way of interaction with the digital
avatars.
C. Dynamics without integration.
Indeed, to calculate motion profiles for every joint of a large chain (such as the case
for the human body), an integrator is typically required. Expensive dynamic packages
do exist but are limited to a small number of degrees-of-freedom. Our true
multi-disciplinary results have yielded a novel method for doing dynamics without the use
of integrators, but rather using optimization techniques. This is a significant
contribution on its own, one that will have a significant impact on all fields where
forward dynamics is needed.
D. Modeling and simulation of clothing
E. Modeling and simulation of muscle fatigue
using differential equations to predict how much Calcium influx is going into the muscles,
and as a result, how much the muscle gets fatigued.
F. A NURBS-FEM real-time method for
calculating muscle deformations and stress.
G. A stable Haptic algorithm for use with
many virtual reality haptic devices and systems. |
