Many researchers in the ergonomics field have been trying to understand how humans use their hands and which factors affect the hand-function capacity. In particular, the physical capacity of the hand has typically been evaluated by biomechanical methodologies. Biomechanical analysis of the human hand can be divided into anthropometry, kinematics, kinetics, and EMG [15].The application of biomechanical principles is important for preventing MSDs in order to improve working conditions and performance. In ergonomics, safety, and health, the hand is mainly evaluated to reduce the risk of MSDs. In product development, the hand is actively studied for the design of hand tools and cell phones. In rehabilitation, the hand is studied to evaluate the difference between patients and healthy individuals. Studying the hand is important for the development of hand-related simulations and robots in the digital manufacturing simulation and intelligence robot fields.
