    Abstract: In various embodiments, methods and systems for determining a forward direction for augmented reality (AR)/virtual reality (VR) are provided. A sideways vector and an up vector are measured by an AR/VR device. A cross product of the sideways vector and the up vector is calculated to obtain a forward vector. An indication from a user of the AR/VR device is received to perform an action in a forward direction and the action in the forward direction is performed in a direction of the forward vector. For example, a user can move in an AR/VR environment in the forward direction or a user interface can be provided in the AR/VR environment in the forward direction.

    Abstract: Changes in image exposure setting may be compensated by creating a table of aggregate differences between corresponding pixels in two images and applying the table of aggregate differences to a portion of one of the two images. The images may be in any color space for visible light, or images not of visible light, such as infrared or depth images. In various configurations, the differences may be aggregated by averaging the differences for pixels of a certain value in one of the two images.

    Abstract: Examples are disclosed herein that relate to processing three-dimensional user input. One example provides a method of processing user input in a three-dimensional coordinate system, comprising receiving a user input of an origin reset for the three-dimensional coordinate system, responsive to receiving the user input of the origin reset, resetting an origin of the three-dimensional coordinate system, receiving three-dimensional user input in the three-dimensional coordinate system, while the origin remains set, measuring at least one three-dimensional displacement of the three-dimensional user input relative to the origin, and causing movement of a user interface element displayed in a user interface, the movement based on the at least one measured three-dimensional displacement.
