Walking

Walking perception by walking observers.

People frequently analyze the actions of other people for the purpose of action coordination. To understand whether such self-relative action perception differs from other-relative action perception, the authors had observers either compare their own walking speed with that of a point-light walker or compare the walking speeds of 2 point-light walkers. In Experiment 1, observers walked, bicycle...

WALKING WALKing walking: Action Recognition from Action Echoes

Recognizing human actions represented by 3D trajectories of skeleton joints is a challenging machine learning task. In this paper, the 3D skeleton sequences are regarded as multivariate time series, and their dynamics and multiscale features are efficiently learned from action echo states. Specifically, first the skeleton data from the limbs and trunk are projected into five high dimensional no...

Walking indoors, walking outdoors: an fMRI study

An observation/execution matching system for walking has not been assessed yet. The present fMRI study was aimed at assessing whether, as for object-directed actions, an observation/execution matching system is active for walking and whether the spatial context of walking (open or narrow space) recruits different neural correlates. Two experimental conditions were employed. In the execution con...

Walking dynamics from walking steady state

1. Motivation. How do humans walk and run stably without falling down? How do humans walk without deviating too much from a roughly periodic steady motion, say, when walking on a treadmill? There are many hundred articles with mechanicsbased mathematical models of bipedal walking and running, that demonstrate stable periodic motion, either due to passive dynamics or due to active control. Such ...
