Abstract: A system for detecting a sound to which a user is attending based on neural signals includes an audio signal collection unit to collect audio signals including two or more sounds from a surrounding environment around the user; a neural signal collection unit to collect the neural signals of the user; an attended sound detection unit to analyze correlations between the two or more sounds included in the audio signals and the neural signals of the user in real time and determine the sound to which the user is attending based on the correlations; a database unit to store a result of the detection; and an output unit to select and output the stored individual audio signal or output the result of detecting the attended sound in real time according to the presence or absence of the audio signal in the surrounding environment around the user.

Abstract: Embodiments are directed to a mobile robot control apparatus for compensating an input delay time, which includes: a user input receiving unit configured to receive a user input for moving a mobile robot from an input device; a waypoint map estimating unit configured to generate an estimated waypoint map in which a waypoint vector is defined for each grid, based on the received user input; an area target determining unit configured to calculate a movable path along which the mobile robot is movable from a current position, and to determine a moving path of the mobile robot based on the calculated movable path and the waypoint vector of the estimated waypoint map; and a driving unit configured to move the mobile robot along the determined moving path, and its control method.

Abstract: A sound source classification step according to an exemplary embodiment of the present disclosure includes the steps for detecting a sound stream for a preset period when a sound signal is generated, dividing the detected sound stream into a plurality of sound frames and extracting a sound source feature for each of the plurality of sound frames, and classifying each of the sound frames into one of pre-stored reference sound sources based on the extracted sound source feature, analyzing a correlation between the classified reference sound sources using the classification results, and classifying the sound stream using the analyzed correlation.
