Arm-Posture Creation Based on Iso-Comfort Regions

Abstract

Finding realistic arm postures for synthetic actors is a complex and important problem in the field of human motion research. But an achievable method for creating them has not yet been proposed. The problem of creating realistic arm posture can be solved in two main steps using the presented algorithm. First, hand posture is created based on a database which is formed using an octree data structure. Classifying the reachable space and forming a database seriously simplifies the creation of hand posture. Second, the posture of the rest of the arm is determined by using iso-comfort regions; a concept introduced by the authors. Obtained results prove the effectiveness of iso-comfort regions from the standpoint of realism.
