Evaluating Arm Movement Imitation
In this paper, we present a metric for assessing the quality of arm movement imitation. We develop a joint-rotational-angle-based segmentation and comparison algorithm that rates pairwise similarity of arm movement trajectories on a scale of 1− 10. We describe an empirical study designed to validate the algorithm we developed, by comparing it to human evaluation of imitation. The results provid...
متن کاملEvaluation Metrics and Results of Human Arm Movement Imitation
We present a psychophysical study of human arm movement imitation, and an approach to analyzing the resulting data, which is general enough to be applied to human or humanoid movement analysis. We describe a joint-space based segmentation and comparison algorithm that allows us to evaluate the performance of 11 different subjects performing a series of arm movement imitation tasks. The results ...
متن کاملEvaluating Classifiers to Detect Arm Movement Intention from EEG Signals
This paper presents a methodology to detect the intention to make a reaching movement with the arm in healthy subjects before the movement actually starts. This is done by measuring brain activity through electroencephalographic (EEG) signals that are registered by electrodes placed over the scalp. The preparation and performance of an arm movement generate a phenomenon called event-related des...
متن کاملRobotic movement elicits automatic imitation.
Recent behavioural and neuroimaging studies have found that observation of human movement, but not of robotic movement, gives rise to visuomotor priming. This implies that the 'mirror neuron' or 'action observation-execution matching' system in the premotor and parietal cortices is entirely unresponsive to robotic movement. The present study investigated this hypothesis using an 'automatic imit...
متن کاملThe power of movement: evidence for context-independent movement imitation.
Recent studies have shown that individuals often imitate the behavior of others. In these studies, the observed and imitated behaviors were always identical. The present research goes one step further and disentangles the imitation of movements from their behavioral contexts. On the basis of theories that the perception of behavior refers to the same mental representations as the execution, we ...
