Abstract: A natural, flexible way for human beings to interact with computers is main goal to
human-computer interaction technology, which is remarkably developing. This goal requires
computers capture and understand humanʹs motion precisely, under this background, motion capture
technology was proposed. As future goal, computer users could send information, commands to
computers not only by clicking and typing, but also by gesture, facial expression and other body
expressions. To achieve this, motion capture technology is definitely indispensable. Currently existing
motion capture systems mostly work for 3D video, which have high costs. However, the improving
integration of MEMS sensor brings lower cost and more demands to motion capture systems. With
integrating existing technologies, this paper proposes a universal motion capture prototype, which
implements the complete process from data measuring, transmitting to motion simulating presence
based on inertial sensor nodes.
