Abstract

The present disclosure relates to methods and systems for establishing ground truth in human state detection. In one embodiment, the disclosure teaches recording physiological data over a continuous duration of at least a threshold duration that is sufficient for capturing representation of the target state in bio signals used for detection. The recorded data is segmented into shorter analysis windows, as a step toward continuous state detection, each window less than the threshold duration, and labeled with a ground truth indicative of the target state. The windows and labels are stored in non-transitory memory, for later use in training, testing, and validating one or more state prediction models. The method enhances the accuracy of state detection models by providing a more representative ground truth through prolonged recordings, which capture the variable manifestations of human states in physiological processes.

Abstract

Disclosed herein are methods and systems for real-time detection of psychophysiological states from eye movement data. The methods involve capturing eye gaze vectors and eyelid openness levels over time using a user-facing camera. A sequence of discrete eye behaviors, including saccades, fixations, blinks, and long closures, is determined from the eye gaze vectors and eyelid openness levels. The sequence of discrete eye behaviors is transformed into a machine readable representation using a sliding time window. A mathematical or machine learning model then maps the machine readable representation of eye behaviors to one or more psychophysiological states. This approach provides a computationally efficient mechanism for predicting psychophysiological states by compressing gaze data into a continuous, numerical representation of eye behavioral events correlated with human psychophysiological states, including drowsiness, cognitive load, stress, and others.

Abstract

An apparatus and method for decreasing noise caused by electromagnetic influence in a headphone are provided, in which a metal plate and a magnetic plate are placed between the electrical loop and the speaker inside the headphone, where the metal plate can be located between the electrical loop and the magnetic plate. When a loop current flowing in the electrical loop varies, an eddy current may be generated on the metal plate with its direction opposing to that of the loop current in the electrical loop. Therefore, the magnetic field generated from the eddy current may actively cancel out the influenced magnetic field brought by the varying loop current.

A waveguide has an opening in the lateral direction, x, and an exit opening in a forward direction, y. The forward direction, y, is generally perpendicular to the lateral direction, x. The waveguide is mounted to the loudspeaker driver so that the opening aligns with a radiating surface of the loudspeaker driver and the exit opening extends along the lateral non-contact surface of the headrest exteriorly to the headrest. The opening is vertically oriented on the lateral non-contact surface of the headrest so that a central axis of radiation of the waveguide is directed toward the forward direction, y. The loudspeaker has an acoustic lens above the loudspeaker driver.

Abstract

In various embodiments, a computer-implemented method for audio processing based on a head pose of a user comprises acquiring one or more images of a user, processing the one or more images to identify a plurality of face landmarks representing locations on a head of the user, selecting, from the plurality of face landmarks and based on an estimated head pose of the user, a set of one or more landmark pairs, determine, based on the set of landmark pairs, three-dimensional positions of ears of the user; and processing one or more audio signals to generate one or more processed audio signals based on the three-dimensional positions of the ears.

Abstract

Techniques for image scaling based on emotion detection are described. In some embodiments, the techniques include acquiring one or more images of a user, processing the one more images to generate emotion-specific three-dimensional (3D) positions of ears of the user based on a 3D head geometry and an emotion of the user, where the emotion is identified based on the one or more images of the user, and processing one or more audio signals to generate one or more processed audio signals based on the three-dimensional positions of the ears. Further embodiments include systems and non-transitory computer-readable media that perform the steps of the method.

Abstract

Described herein are methods and systems for a vehicle system which provide inbuilt road noise cancellation in the vehicle. In one or more embodiments, a method for road noise cancellation comprises using a head-tracking device to monitor an occupant ear position, capturing airborne noise using a feedforward microphone and a headrest microphone of a zone in which the occupant ear is positioned, updating acoustic path information according to the occupant ear position(s) and speaker position(s) within the zone, generating a noise cancellation signal using sampling rate greater than 2 kHz, and outputting the noise cancellation signal via a headrest speaker located near the zone in which the occupant ear is positioned to at least partially reduce a road noise sound level in the zone.

Abstract

Disclosed are techniques for ambient sound generation. Some aspects of ambient sound generation involve determining target ambient sound information based on ambient sound design reference information, determining ambient sound generation information based on the target ambient sound information, where the ambient sound generation information identifies one or more subordinate ambient sounds and one or more feature parameters corresponding to the one or more subordinate ambient sounds, and generating a target ambient sound based on the ambient sound generation information.
