Study on Manipulating a Virtual Object in a Large Screen Close to the User by Visual Analysis of Small-Scale Movements of Forefinger, Hand and Face

摘要

In recent virtual reality systems, the virtual scenes tend to be displayed in a large screen. In such a system, virtual objects in the displayed virtual scene should be able to be manipulated by a human hand, but as the screen size or the size of the projected area gets larger, the manipulation range tends to get large, which is painful and inefficient for humans. In this thesis, we present a feasible solution to solve long distance hand motions by combining estimation of finger's and hand's pose and estimation of face direction.
