Hand skin deformation is a significant role in the virtual ergonomic assessment of handheld products. In this paper, a nonlinear elasticity model is used to simulate the skin contact deformation, and quasi volume preserving property of skin is considered for more realistic simulation. An efficient contact solving method is developed for simulating the physical contact with product surfaces. The hand surface skin is partitioned anatomically into different regions for being able to specify different physical properties in them and for efficient simulation for the ergonomic assessment of grasp ability. The realistic contact deformation effect was efficiently realized, and was experimentally verified. The verification results show that the proposed skin deformable model is effective, in the acceptable range for virtual ergonomic assessment.
