Abstract

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

Walking

Walking (also known as ambulation) is one of the main gaits of terrestrial locomotion among legged animals. Walking is typically slower than running and other gaits. Walking is defined by an 'inverted pendulum' gait in which the body vaults over the stiff limb or limbs with each step. This applies regardless of the usable number of limbs—even arthropods, with six, eight, or more limbs, walk. In humans, walking has health benefits including improved mental health and reduced risk of cardiovascular disease and death.

Motor coordination

In physiology, motor coordination is the orchestrated movement of multiple body parts as required to accomplish intended actions, like walking. This coordination is achieved by adjusting kinematic and kinetic parameters associated with each body part involved in the intended movement. The modifications of these parameters typically relies on sensory feedback from one or more sensory modalities (see multisensory integration), such as proprioception and vision.

Degrees of freedom problem

In neuroscience and motor control , the degrees of freedom problem or motor equivalence problem states that there are multiple ways for humans or animals to perform a movement in order to achieve the same goal. In other words, under normal circumstances, no simple one-to-one correspondence exists between a motor problem (or task) and a motor solution to the problem.
