This paper presents a collision-free task planning method for dual manipulators by introducing shadow space modeling concept. The shadow space is defined as a subset of working space that is occupied by the robot's movement. The collision can be detected and prevented by computing the intersection of two manipulators' shadow spaces. Then a novel genetic algorithm with mutual exclusive chromosomes...
An affective classification technology plays a key role in the affective human and computer interaction. This paper presents an affective classification method based on the Bayes classifier and the supervisory learning. We newly define a weighted-log-posterior function for the Bayes classifier, instead of the posterior function or the likelihood function that is used in the ordinary Bayes classifier...
This paper presents the initial studies of spectral analysis of the electroencephalogram signals for emotion recognition. Two-dimensional emotion model of valence and arousal is used to represent emotion, which is advantageous in quantifying the emotion. Ninety photographs, categorized into high valence-high arousal, medium valence-low arousal, and low valence-high arousal groups, were chosen from...
