This paper presents techniques that enable talker tracking for effective human-robot interaction. To track moving people in daily-life environments, localizing multiple moving sounds is necessary so that robots can locate talkers. However, the conventional method requires an array of microphones and impulse response data. Therefore, we propose a way to integrate a cross-power spectrum phase analysis...
In this paper, a single speaker tracking mechanism with particle filter is presented for a reliable interaction with robot. To have a smooth tracking result, we use not only audio data but also video data. For sound observation, we use Time Delay Of Arrival (TDOA) between two microphones, and in order to expect high reliability in the likelihood of localization, we apply variable sensitivity values...
The purpose of this study is to develop a violin playing robot that can produce expressive sounds by considering kansei, which is a Japanese word whose meaning resembles sensibility. The goal of this paper is to realize bowing by an anthropomorphic robot arm and to analyze the sounds it produces. First, we propose a model of information flow in musical instrument playing, which is a key concept of...
