    摘要： Systems and methods are provided herein for providing spatial audio cues for notifying a user of a user interface (“UI”) element in augmented reality (“AR”). This may be accomplished by a system determining a location and orientation of a device, and then determining an estimated augmented reality view using the location and orientation of the device. The system may then determine whether a UI element is within the augmented reality view. If the UI element is within the augmented reality view, the system can play an audio cue signaling a position of the UI element using audio spatialization. After hearing the audio cue, the user may then view the UI element in AR using the device.

    摘要： A power-over-Ethernet (PoE) powered multichannel streaming audio amplifier includes a plurality of Ethernet ports each configured to be coupled to an Ethernet cable and capable of receiving power and audio data transmitted over the Ethernet cables. Power supply circuitry connected to the Ethernet ports is configured to combine and manage the power received at the Ethernet ports. A microprocessor subsystem powered by the power supply circuitry is configured to receive and process the audio data to generate output audio signals. A digital audio amplifier powered by the power supply circuitry amplifies the output audio signals received from the microprocessor system. A plurality of audio outputs connected to the digital audio amplifier are each configured to be connected to a different one of a plurality of speaker devices to transmit the audio output signals amplified by the digital audio amplifier to the plurality of speaker devices.

    摘要： A media system and a method of using the media system to reproduce spatial audio based on head-to-torso orientation, are described. The method includes determining a head-to-source orientation and a head-to-torso orientation based on head orientation data generated by a head tracking device. Determining the head-to-torso orientation includes determining torso movements based on movements of the head. The torso can be determined to move when the head movements meet a head movement condition, such as a predetermined angle of movement or pattern of movement. A binaural audio filter that is based on a head-related transfer function corresponding to both the head-to-source orientation and the head-to-torso orientation is applied to an audio input signal to generate an audio output signal. The audio output signal is played to accurately recreate spatial audio having sounds emitted to the user by a sound source. Other aspects are also described and claimed.
