Proceedings ArticleDOI
Robot audition for dynamic environments
TL;DR: This paper addresses robot audition for dynamic environments, where speakers and/or a robot is moving within a dynamically-changing acoustic environment, and develops new techniques for a robot to listen to several things simultaneously using its own ears even in dynamic environments; MUltiple SIgnal Classification based on Generalized Eigen-Value Decomposition, GEVD-MUSIC, and HRLE.

TL;DR: A sound processing device includes a separation unit configured to separate at least a music signal and a speech signal from a recorded audio signal, a noise suppression unit, a music feature value estimation unit, speech recognition unit, and a noise processing confidence calculation unit as mentioned in this paper.
Proceedings ArticleDOI
Remote heart rate variability for emotional state monitoring
TL;DR: The method is based on a remote photoplethysmography (rPPG) algorithm that estimates remote Heart Rate Variability (rHRV) using a simple camera and shows that there is a strong correlation between the rHRV feature and different emotional states.
Proceedings ArticleDOI
SoundCraft: Enabling Spatial Interactions on Smartwatches using Hand Generated Acoustics
TL;DR: The algorithm, which is described, adopts from the MUltiple SIgnal Classification (MUSIC) technique, that enables robust localization and classification of the acoustics when the microphones are required to be placed at close proximity is described.

Sound source-separating device and sound source -separating method
TL;DR: A sound source-separating device as discussed by the authors includes a sound-collecting part, an imaging part, a sound signal-evaluating part, and a selection part that selects whether to estimate a sound source direction based on the first sound signal or the first image signal.
