Abstract: In device having at least one microphone and one or more speakers, environmental sound may be recorded using the microphone, classified and mixed with source media sound to produce a mixed sound depending on the classification. The mixed sound may then be played over the one or more speakers.

Abstract: To derive three dimensional (3D) position and orientation of a 3-axis (or more) magnetometer/accelerometer device (such as may be implemented in VR or AR headset or computer game controller) without line of sight constraints, a spinning magnetic field is used to discriminate and remove the external (Earth's) magnetic field from the spinning magnetic field. This reduces the problem to finding the distance to the source of the magnetic field using a calibration table (or formula), finding two angles describing the deviation of the magnetic sensor from the axis of rotation of the spinning magnetic field and the phase around this axis, and from these values deriving the orientation of the sensor.

Abstract: Plural individual sensor assemblies are engaged with respective parts of a person's body. Each assembly may include accelerometers, magnetometers, and gyroscopes. Sensor data is fused together to get the orientation at each body location. To simplify, the body is assumed to consist of rigid bars of known length connected with ball joints so that once the relative orientations of all bars are given by the respective assemblies, body pose can be computed. Then the body pose is translated as a virtual body into a virtual world either by a ray cast method that anchors a foot of the virtual body to the ground assuming infinite gravity and infinite friction and then translating the other body parts to make the ground contact point fixed, or by implementing an approximate dynamics physics engine on the virtual body. The technique may be used in VR location-based entertainment and for motion capture.

Abstract: An audio converter system is provided. The system comprises an audio input configured to receive a source audio, an audio output configured to couple to a hybrid speaker comprising at least two nondirectional speakers and a directional speaker, and a processor configured to generate an output audio for the hybrid speaker based on the source audio by: identifying a specific sound in the source audio, isolating the specific sound from the source audio, generating a directional speaker output for the directional speaker of the hybrid speaker based on the specific sound, and generating at least two channels of nondirectional speaker output for the at least two nondirectional speakers of the hybrid speaker.

Abstract: In an audio headset having one or more far-field microphones mounted to the headset; and one or more speakers mounted to the headset environmental sound may be recorded using the one or more far-field microphones, classified and mixed with source media sound to produce a mixed sound depending on the classification. The mixed sound may then be played over the one or more speakers.

Abstract: Environmental sound is recorded using one or more microphones. A source of the recorded environmental sound is classified. The recorded environmental sound is weighted based on the classification of the source and the source media sound using a weighting mode to determine whether to mix the recorded environmental. The recorded environmental sound is mixed with source media sound to produce a mixed sound based on the determination. The mixed sound is played over one or more speakers.
