To achieve ultra-realistic communications (URC), a three-dimensional (3D) sound field recording and reproducing system using spatial sound features is promising. It utilizes sound source positions and original source signals as features. On the other hand, sound source orientations (such as speaker's orientation) have been neglected, though they are necessary for high-performance URC. In this paper,...
This paper proposes real-time sound source orientation estimation based on orientation-extended amplitude beamforming (OE-ABF). To recognize a sound source orientation (such as face orientation) is an important function for a robot who can achieve natural human-robot interaction because the function is required to distinguish the human target from a robot or another person. We developed a sound source...
According to increase in the number of sensors, the target system could be effectively controlled such as monitor and maintenance. Additionally, transparent causality among sensor signals should be importantly prerequisite for realizing that kind of solution. However, it is very hard to acquire the cause-effect structure among huge number of sensors. In this article, cause-effect structure acquisition...
In order to realize heart rate monitoring on a bed, there are mainly two types of approaches similar to other signal processing applications: frequency domain analysis and time-series domain analysis. In frequency domain analysis, FFT is widely used to extract heart rate from obtained signals. Since FFT assumes constant frequency, it cannot be used for extracting microscopic variability of heart rate...
In a factory setting, the zero-breakdown concept of manufacturing processes has been eagerly anticipated. In this article, the notion of machine health management technology is introduced in response to this requirement. The technology employs a cyclical and evolutional problem-solving approach using cause-effect structures. This paper will utilize an automatic acquisition method by using sensing...
The main achievement in future analysis is to acquire causality, transparency and accuracy utilizing human-machine collaboration. We propose a process of close interaction between humans and machines for system modeling, which is backed up by a method to combine human expert knowledge with the performance of information criteria. This approach not only promises the best accuracy but also interdisciplinary...
