We propose a novel design of artificial robot ear for sound direction estimation using measured two outputs only. The spectral features in head-related transfer functions and in interaural transfer functions (ITFs) are distinctive in the voice frequency band. Thus, these features provide effective sound cues to estimate the sound direction using two measured ear outputs only without input information...
In this paper, the feasibility of multiple targets localization with a ultrasonic transmitter and only two ultrasonic sensors are tested and its results are given. For this purpose, an experimental hardware system and algorithm which models after bat's vocalization and auditory pathway are built. To mimic bat's behavior features, bat's chirp composed of single band/full band signal component and frequency...
Interaction between humans involves a plethora of sensory information, both in the form of explicit communication as well as more subtle unconsciously perceived signals. In order to enable natural human-robot interaction, robots will have to acquire the skills to detect and meaningfully integrate information from multiple modalities. In this article, we focus on sound localization in the context of...
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...
