Abstract: A computer that includes a processor and a memory, the memory including instructions executable by the processor to generate a current keyframe point cloud based on pairs of stereo images while a stereo camera travels through a scene determine a similar viewpoint query matrix and an opposing viewpoint query matrix based the current keyframe point cloud. A distance matrix and an opposing view distance matrix can be generated by comparing the similar viewpoint query matrix and the opposing viewpoint query matrix to reference matrices. A relative pose between a stereo camera and a reference can be determined to determine a location in the scene during travel of the stereo camera through the scene by performing sequence matching in the distance matrix and the opposing view distance matrix to determine a minimum sequence.

Abstract: Device context-based user interface techniques are described. In one or more embodiments, a context is determined for a device based on a configuration of hardware associated with the device. When the configuration of hardware associated with the device changes, the context of the device may also change. Based on the determined context of the device, a user interface configuration may be selected for display. For example, when the device is connected to a mouse or a keyboard a user interface configuration may be selected that facilitates interactions performed substantially with a mouse and keyboard. However, when a mouse and keyboard are not connected to the device, but touch functionality of the device is used, a user interface configuration may be selected that facilitates interactions performed substantially using the touch functionality. A user interface for an application may be configured using the selected user interface configuration.
