As we know, human hand is an amazing instrument that can perform a multitude of functions, such as the power grasp and precision grasp of a vast array of objects, with ease and an absence of effort. Although expended great attempts by scientists and engineers, there is no artificial hand matching the amazing capacity of human hand. The origins of human hand remain unclear. It is too miraculous to let us think that human hand is the masterwork of Creator and indicates the mystery of nature. The further discussion about the Creator is indeed out of place in our article.
We have noticed the problems of the inaccurate measurement by CyberGlove. The primary neighboring influence of the reading occurs in the abduction/adduction sensors. The problem does not affect our work to a great extent. In our work, we only measure the abduction-adduction movement of thumb and the correlated relationship about abduction-adduction movement is also neglected because the measured joint angle is not the real angular value of CMC joint of thumb, which is a non-orthogonal and non-intersecting compound joint.
