Abstract: A system may include an electronic device such as a head-mounted device and a handheld controller for controlling the electronic device. The handheld controller may have a housing with an elongated shaft extending between first and second tip portions. The handheld controller may have power receiving circuitry configured to receive power from a power source. The power source may be incorporated into an electronic device such as a wireless charging dock or stick, a battery case, or a head-mounted device. The power source may supply power through terminals that form ohmic contacts with mating terminals in the finger device or may transmit power wirelessly using capacitive coupling or inductive charging arrangements. Magnets may be used to hold and align the elongated shaft of the handheld controller on the power source.

Abstract: A display system includes a head-mounted display unit and a detachable speaker unit. The head-mounted display unit outputs visual content to a user and provides a visual pass-through of a real environment to the user. The detachable speaker unit is detachably coupleable to the head-mounted display unit for providing aural content to the user. At least one of the visual content or the aural content is changed according to a position of the detachable speaker unit relative to the head-mounted display unit.

Abstract: A method for self-calibrating a sound pickup process that uses a microphone array in a wearable device that also includes a loudspeaker, where the microphone array being in a physical arrangement with respect to the loudspeaker. The method obtains, for each of several microphones of the microphone array, one or more transfer functions that each represent a response of the microphone to sound from a position in an acoustic space. The method determines whether a physical arrangement of the microphone array with respect to the loudspeaker has changed and adjusts the transfer function, for at least one of the microphones of the several microphones, in response to determining that the current physical arrangement of the microphone array with respect to the loudspeaker has changed.

Abstract: Channels of audio data in a spatial audio object are associated with any one or more of a direction and a location of one or more recorded sounds, which channels are to be reproduced as spatial sound. A visualized spatial sound object represents a snapshot/thumbnail of the spatial sound. To preview the spatial sound (by experiencing its snapshot or thumbnail), a user manipulates the orientation of the visualized spatial sound object, and a weighted downmix of the channels is rendered for output as a spatial preview sound, e.g., a single output audio signal is provided to a spatial audio renderer; one or more of the channels that are oriented toward the user are emphasized in the preview sound, more than channels that are oriented away from the user. Other aspects are also described and claimed.

Abstract: In one implementation, a method includes: obtaining a first depth estimation characterizing a distance between the device and a surface in a real-world environment, wherein the first depth estimation is derived from image data including a representation of the surface; receiving, using the audio transceiver, an acoustic reflection of an acoustic wave, wherein the acoustic wave is transmitted in a known direction relative to the device; and determining a second depth estimation based on the acoustic reflection, wherein the second depth estimation characterizes the distance between the device and the surface in the real-world environment; and determining a confirmed depth estimation characterizing the distance between the device and the surface based on resolving any mismatch between the first depth estimation and the second depth estimation.

Abstract: A first device obtains, from the array, several audio signals and processes the audio signals to produce a speech signal and one or more ambient signals. The first device processes the ambient signals to produce a sound-object sonic descriptor that has metadata describing a sound object within an acoustic environment. The first device transmits, over a communication data link, the speech signal and the descriptor to a second electronic device that is configured to spatially reproduce the sound object using the descriptor mixed with the speech signal, to produce several mixed signals to drive several speakers.
