摘要： Camera compensation methods and systems that compensate for misalignment of sensors/camera in stereoscopic camera systems. The compensation includes identifying a pitch angle offset between a first camera and a second camera, determining misalignment of the first and second cameras from the identified pitch angle offset, determining a relative compensation delay responsive to the determined misalignment, introducing the relative compensation delay to image streams produced by the cameras, and producing a stereoscopic image on a display from the first and second image streams with the introduced delay.

摘要： Systems and methods for determining a location of a wearable electronic device are disclosed. In some aspects, the device includes a position acquisition device and an accelerometer. A hardware processor included in the device may be configured to generally maintain the position acquisition device in a low power state to save power. When a video or image is captured, it may tag the video or image with first location information. Given the inoperative position acquisition device, a current location may not be known. In some aspects, in response to a need for location information, measurements from an accelerometer may be stored. The position acquisition device may also be transitioned to an operative state, and after some time delay, a second location determined. In some aspects, the location of the capture may then be obtained based on the acceleration measurements and the second location.

摘要： Eyewear including a frame having a first side and a second side, a first temple extending from the first side of the frame, a second temple extending from the second side of the frame, electronic components, a first system on a chip (SoC) adjacent the first side of the frame coupled to a first set of the electronic components, and a second system on a chip adjacent the second side, the second SoC coupled to the first SoC and to a second set of the plurality of electronic components. Processing workloads are balanced between the first SoC and the second SoC by performing a first set of operations with the first SoC and performing a second set of operations with the second SoC.

摘要： Example systems, devices, media, and methods are described for efficiently processing an audio track of a virtual object with a head-related transfer function (HRTF). Audio tracks are processed by determining a current position (direction and optionally distance) of the virtual object with respect to the head of a user, identifying a current audio zone from predefined audio zones responsive to the determined current position where each of the audio zones has a corresponding left predefined filter and a corresponding right predefined filter, applying the left and the right predefined filters corresponding to the current audio zone to the audio track to produce a left audio signal and a right audio signal, and presenting the left audio signal with a first speaker and the right audio signal with a second speaker.
