On Using Virtual Reality Tools to Study the Motion of a Human Hand Artificial Model

The human hand is a complex mechanism, very difficult to model and to mimic. There are many fields, which require the use of a hand model: computer games, VR simulations, human hand prostheses design, etc. Depending on the domain, the hand model will be more or less similar with the natural model, every time some approximations being necessary. This paper presents a human hand model intended to be used as basis to design an artificial hand able to assure the prehension function. The motion model was studied using VR tools to determine the trajectories and the angles for various activities.
