Natural Postural Adjustments for Physics-based Characters

This page presents the project Natural Postural Adjustments for Physics-based Characters.

Description

A wide class of human motions involve neither walking nor standing still like a statue. Postural adjustments can be found abundance in real motions, and often involves shifting the weight between feet or a small-scale repositioning of the feet. This can be in support of a secondary task, or simply part of the natural tendency to never fully stop moving. How can we simulate such motions? This project is about developing control strategies for such motions and comparing them side-by-side with real video footage of the similar motions that people perform. Simple in-place dancing, i.e, not ballroom dancing, waltzing, or salsa) is also within the scope of this project, as it involves body movement without large displacements of the feet.

Discussion

How do people take small steps? How do they "spin" on their heels and toes?
