Curved Path Walking
Research on biped locomotion has focused on sagittal plane walking in which the stepping path is a straight line. Because a walking path is often curved in a three dimensional environment, a 3D locomotion subsystem is required to provide general walking animation. In building a 3D locomotion subsystem, we tried to utilize pre-existing straight path (2D) systems. The movement of the center of th...
متن کاملPath integration: effect of curved path complexity and sensory system on blindfolded walking.
Path integration refers to the ability to integrate continuous information of the direction and distance traveled by the system relative to the origin. Previous studies have investigated path integration through blindfolded walking along simple paths such as straight line and triangles. However, limited knowledge exists regarding the role of path complexity in path integration. Moreover, little...
متن کاملWhen Good Enough Is Best
In this issue of Neuron, Rinberg et al. show that mice use a speed-accuracy tradeoff in odor discrimination. Shorter sampling results in high performance for easy problems, and enforced longer sampling results in higher accuracy for difficult problems, but mice freely choose intermediate sampling durations and accuracy varies with difficulty. Reward value and task requirements may determine sam...
متن کاملWhen is vestibular information important during walking?
Locomotion relies on vision, somatosensory input, and vestibular information. Both vision and somatosensory signals have been shown to be phase dependently modulated during locomotion; however, the regulation of vestibular information has not been investigated in humans. By delivering galvanic vestibular stimulation (GVS) to subjects at either heel contact, mid-stance, or toe-off, it was possib...
متن کاملCurved walking in hemiparetic patients.
OBJECTIVE Curved walking requires complex adaptations, including shift of body weight to counteract the ensuing centrifugal force, and the production of strides of different length between legs. We hypothesized that gait capacities would be more stressed in hemiparetic patients than in healthy subjects when walking along curved, compared with straight, trajectories. METHODS Twenty chronic, st...
