    Abstract: A method includes determining, at a first time, a representation of a first head rotation of a head mounted display (HMD) using a first inertial sensor sample stream and rendering, at an application processor, a texture based on the first head rotation. The method further includes determining, at a second time subsequent to the first time, a representation of a second head rotation of the HMD using a second inertial sensor sample stream having a higher sampling rate than the first inertial sensor sample stream, and generating, at a compositor, a rotated representation of the texture based on a difference between the first head rotation and the second head rotation.

    Abstract: A method includes sequentially outputting from an imaging sensor each pixel row of a set of pixel rows of an image captured by the imaging sensor. The method further includes displaying, at a display device, a pixel row representative of a first pixel row of the captured image prior to a second pixel row of the captured image being output by the imaging sensor. An apparatus includes an imaging sensor having a first lens that imparts a first type of spatial distortion, a display device coupled to the imaging sensor, the display to display imagery captured by the imaging sensor with the first spatial distortion, and an eyepiece lens aligned with the display, the eyepiece lens imparting a second type of spatial distortion that compensates for the first type of spatial distortion.

    Abstract: Systems and methods for generating or enhancing representations of an interior space using data collected by a device, such as a mobile device, capable of simultaneous localization and mapping. An electronic device, such as a mobile device, can be configured to collect data using a variety of sensors as the device is carried or transported through a space. The collected data can be processed and analyzed to generate geometry data providing a three-dimensional representation of the space and objects in the space in near real time as the device is carried through the space. The geometry data can be used for a variety of purposes, including generating and/or enhancing models and other representations of an interior space, and/or assisting with navigation through the interior space.
