Publication number: 20240105156Abstract: The disclosed computer-implemented method may include applying, via a sound reproduction system, sound cancellation that reduces an amplitude of various sound signals. The method further includes identifying, among the sound signals, an external sound whose amplitude is to be reduced by the sound cancellation. The method then includes analyzing the identified external sound to determine whether the identified external sound is to be made audible to a user and, upon determining that the external sound is to be made audible to the user, the method includes modifying the sound cancellation so that the identified external sound is made audible to the user. Various other methods, systems, and computer-readable media are also disclosed.Type: ApplicationFiled: December 6, 2023Publication date: March 28, 2024Inventors: Andrew Lovitt, Antonio John Miller, Philip Robinson, Scott Phillip Selfon

Publication number: 20240036814Abstract: This disclosure describes embodiments of methods, non-transitory computer-readable media, and systems for detecting that a physical space includes a physical object corresponding to an analogous virtual object from an augmented reality experience and rendering (or otherwise modifying) the augment reality experience to integrate the physical object as part of the experience. In particular, the disclosed systems can determine that a physical object within a physical environment corresponds to an analogous virtual object of an augmented reality experience. Based on this correspondence, the disclosed systems can modify one or more of the virtual graphics, sound, or other features corresponding to the augmented reality experience to represent the virtual object using the physical object. For example, the disclosed systems can modify acoustic features of a sound for the augmented reality experience to simulate the sound originating from (or being affected by) the physical object.Type: ApplicationFiled: September 11, 2023Publication date: February 1, 2024Inventor: Andrew Lovitt

Publication number: 20230232178Abstract: A communication system provides audio content to one or more client devices capable of playing spatialized audio content. For example, the communication system receives audio content from a client device and transmits the audio content to other client devices to be played for users. The communication system dynamically modifies audio content transmitted to different client devices based on a payload including audio parameters (e.g., local area acoustic properties, an audiogram for a user, a head related transfer function for a user, etc.) received from a client device.Type: ApplicationFiled: January 19, 2022Publication date: July 20, 2023Inventors: Andrew Lovitt, Nils Thomas Fritiof Lunner, Vladimir Tourbabin, Jacob Ryan Donley

Publication number: 20230217201Abstract: An audio system of a client device applies transformations to audio received over a computer network. The transformations (e.g., HRTFs) effect changes in apparent source positions of the received audio, or of segments thereof. Such transformations may be used to achieve “animation” of audio, in which the source positions of the audio or audio segments appear to change over time (e.g., circling around the listener). Additionally, segmentation of audio into distinct semantic audio segments, and application of separate transformations for each audio segment, can be used to intuitively differentiate the different audio segments by causing them to sound as if they emanated from different positions around the listener.Type: ApplicationFiled: January 3, 2022Publication date: July 6, 2023Inventors: Andrew Lovitt, Scott Phillip Selfon

Publication number: 20230196765Abstract: A client device of a user (e.g., a headset) provides a software-based user interface, not relying solely on physical buttons built into the client device itself. The client device's user interface system can render the user interface using graphical, virtual user interface elements that take the place of physical buttons, reducing device manufacturing costs, improving user interface reliability, and allowing greater user interface flexibility. Information on user movements can then be obtained using a separate wearable device, and the client device can use such information to determine whether the user's movements indicate interactions with the virtual user interface elements, taking appropriate actions if so. The client device's user interface system can also render the user interface using sounds made to appear to emanate from particular locations. Subsequent user movements can then be analyzed to determine whether they indicate the particular locations corresponding to the sound-based elements.Type: ApplicationFiled: December 21, 2021Publication date: June 22, 2023Inventors: Andrew Lovitt, Sebastian Sztuk

Patent number: 11644894Abstract: A method comprising determining a set of position parameters for an inertial measurement unit (IMU) on a headset worn by a user. The set of position parameters includes at least a first yaw measurement and a first roll measurement. The set describes a pointing vector. The method further comprises calculating a drift correction component that describes a rate of correction. The drift correction component is based at least in part on the set of position parameters. The method further comprises applying the drift correction component to one or more subsequent yaw measurements for the IMU. The drift correction component forces an estimated nominal position vector to the pointing vector at the rate of correction.Type: GrantFiled: June 22, 2022Date of Patent: May 9, 2023Assignee: Meta Platforms Technologies, LLCInventors: William Owen Brimijoin, II, Andrew Lovitt

Patent number: 11616580Abstract: A system receives audio data in a frequency range of 20 Hz-20 kHz. The received audio data is encoded by the system into ultrasonic data in frequencies that are greater than 20 kHz, and transmitted into a local area that is proximal to the transmitting device, i.e., within the transmission range of the transmitting device. An ultrasonic communication device that is located in the transmission range of the transmitting device may receive the ultrasonic data. The received ultrasonic data is decoded by the ultrasonic communication system in the receiving device into audio data in a frequency range of 20 Hz-20 kHz, and subsequently presented to a user of the receiving ultrasonic communication device.Type: GrantFiled: May 9, 2022Date of Patent: March 28, 2023Assignee: Meta Platforms Technologies, LLCInventors: Peter Harty Dodds, Morteza Khaleghimeybodi, Philip Robinson, Scott Phillips Porter, William Owen Brimijoin, II, Andrew Lovitt

Patent number: 11563855Abstract: A system controls the audio focus for a user in a virtual conference call. The system retrieves sound parameters associated with participants in the virtual conference call with the user from a user profile of the user. The sound parameters define volume adjustments to be applied to audio data received from the participants for generating an audio mix customized to the user. The system receives the audio data from client devices of the participants, and for each of the participants, adjusts the audio data of the participant using the associated sound parameter of the participant. The system adds the adjusted audio data of the participants to the audio mix for the user and provides the audio mix to a client device of the user.Type: GrantFiled: May 14, 2021Date of Patent: January 24, 2023Assignee: Meta Platforms Technologies, LLCInventors: Igor D.
