“…All these improvements can make the skin deformation more smooth (see Figure 8(h)). Zhou and Zhao [55] presented a skin deformation algorithm for creating 3D characters or virtual human models. The algorithm can be applied to rigid deformation, joint-dependent localized deformation, skeleton driven deformation, crosscontour deformation, and free-form deformation (FFD).…”

This paper surveys the modeling methods for deformable human body and motion analysis in the recent 30 years. First, elementary knowledge of human expression and modeling is introduced. Then, typical human modeling technologies, including 2D model, 3D surface model, and geometry-based, physics-based, and anatomy-based approaches, and model-based motion analysis are summarized. Characteristics of these technologies are analyzed. The technology accumulation in the field is outlined for an overview.

“…Human skin exhibits elasticity and undergoes deformation when subjected to various motion postures. Existing studies on skin deformation primarily rely on the utilization of 3D human models 10 – 13 , 2D planar segmentation measurement techniques 14 – 18 , and 3D scanning methods for landmark measurements 19 , 20 . The human hand comprises 8 wrist bones, 5 metacarpals, 14 finger bones, numerous muscles, and well-developed nerves 21 , which possesses an exceptionally high degree of freedom compared to other body parts, making it challenging to construct a 3D model for computing skin deformation.…”

To investigate the influence of different grasping postures on the hand’s skin deformation, a handheld 3D EVA SCANNER was used to obtain 3D models of 111 women in five postures, including a straight posture and grasping cylinders with various diameters (4/6/8/10 cm). Skin relaxation strain ratio ($${\lambda }_{p}$$ λ p ) and surface area skin relaxation strain ratio ($${\lambda }_{m}$$ λ m ) were used as measures of skin deformation between two landmarks and multiple landmarks, respectively. The effects of grasping posture on skin deformation in different directions were analyzed. The results revealed significant variations in skin deformation among different grasping postures, except for the width of middle finger metacarpal and the length of middle finger’s proximal phalanx. The $${\lambda }_{p}$$ λ p increased with decreasing grasping object diameter, ranging from 5 to 18% on the coronal axis, and from 4 to 20% on the vertical axis. The overall variation of $${\lambda }_{m}$$ λ m ranged from 5 to 37.5%, following the same trend as $${\lambda }_{p}$$ λ p except for the surface area of tiger’s mouth, which exhibited a maximum difference of 10.9% with significant differences. These findings have potential applications in improving the design of hand equipment and understanding hand movement characteristics.
