Dynamic strategies of human postural control

The two goals pursued in this study were to identify controllable dynamic characteristics of human posture and to approach the description of these characteristics by means of computer graphics. The notion that virtual time-to-contact, which specifies the spatio-temporal proximity of the pressure center to the stability boundary is one of the controllable parameters for postural dynamics, was examined while subjects performed a variety of upright postural movements where the speed, instructions and the base of support dimensions were experimentally manipulated. The rational for the new concept of virtual time-to-contact as well as a method for its computation and visualization with respect to two-dimensional stability boundary were elaborated.
