During locomotion, a top-down organization has been previously demonstrated with the head as a stabilized platform and gaze anticipating the horizontal direction of the trajectory. However, the quantitative assessment of the anticipatory sequence from gaze to trajectory and body segments has not been documented. The present paper provides a detailed(More)
In order to self-organize symbols from observed motion patterns, it is necessary to temporally segment the continuous motion pattern flows into meaningful chunks. For reusability of the acquired information, repeatedly observed patterns are important, which means that segmentation, memorization, recognition and abstraction depend on each other. From this(More)
The emotional component of human walking patterns can be characterized by a limited set of kinematic cues [8]. Here, we tested whether artificial synthesis of emotional gaits based on these cues can facilitate emotion perception in human observers. To this purpose, we recorded neutral gaits and artificially modified the walking speed, the upper-body posture(More)
As one of several characteristics of hemiplegic patients after stroke, compensatory gait caused by affected limb is often seen. The purpose of this research is to apply a symmetry-based controller of a wearable type lower limb robot, Hybrid Assistive Limb (HAL) to hemiplegic patients with compensatory gait, and to investigate improvement of gait symmetry.(More)
Recent litterature suggested a top-down organization of locomotion, with the head being the stable frame of reference and the gaze anticipating the future direction. The present paper provides detailed investigation into the spatial and temporal relationship among the gaze and each body segment during locomotion on a complex trajectory without visual cues(More)
In this research we introduce a wearable sensory system for motion intention estimation and control of exoskeleton robot. The system comprises wearable inertial motion sensors and shoe-embedded force sensors. The system utilizes an instrumented cane as a part of the interface between the user and the robot. The cane reflects the motion of upper limbs, and(More)
We quantitatively measured the smiles of a child with autism spectrum disorder (ASD-C) using a wearable interface device during animal-assisted activities (AAA) for 7 months, and compared the results with a control of the same age. The participant was a 10-year-old boy with ASD, and a normal healthy boy of the same age was the control. They voluntarily(More)
CONTEXT The hybrid assistive limb (HAL) is a wearable robot suit that assists in voluntary control of knee and hip joint motion by detecting bioelectric signals on the surface of the skin with high sensitivity. HAL has been reported to be effective for functional recovery in motor impairments. However, few reports have revealed the utility of HAL for(More)
In associative neural networks with nonmonotonic activation functions which store hierarchically correlated patterns, bifurcations of attractors take place depending on the parameter of nonmonotonicity. With hierarchically correlated storage patterns, attractors are the stored patterns when the nonmonotonicity is large, and new emergent patterns at around(More)
Several methods have been investigated and realized for operation of exoskeleton robots for assistance of human gait. These systems perform motion intention estimation using the bioelectrical signals of muscle activation, body gestures and kinesiological information, or a mixed combination in a hybrid system. For motion intention estimation of the lower(More)
