An interactive tool for the design of human free-walking trajectories

Presents an interactive tool dedicated to the design of walking trajectories for human figures. It uses a global human free-walking model built from experimental data on a wide range of normalized velocities. This tool is particularly efficient in that the higher level of the walking model works independently from the effective play of the low level joint trajectories by the figure. This independence is gained by means of a transfer function calibrating the figure's normalized velocity with respect to the theoretical normalized velocity. Two real-time display functionalities greatly ease the design of trajectories in complex environments. First, the current range of permitted velocities indicates the potentialities of the local dynamics of the walking behavior. Second, the set of step locations shown on the desired path allows precise placement
