Abstract: A system for tracking a position and an orientation of an external device such as a smart watch or a handheld controller relative to a head mounted display (HMD) device is provided. A combination of active markers and passive markers on the external device may be detected by a point tracking camera of the HMD to collect position data for the external device relative to the HMD. Acceleration and/or orientation data of the external device relative to the HMD may be collected from an inertial measurement unit(s) (IMU(s)) of the external device and/or the HMD. The fusion of the position data with the data collected by the IMU(s) may allow for tracking of the external device relative to the HMD.

Abstract: A vehicle mounted imaging system tracks and resolves image using an object image regions of interest at a higher resolution than that which can be provided by typical wide-angle optics. The imaging system includes an object identification camera, a sampling camera, and one or more computing devices. The one or more computing devices obtain a full-frame image from the object identification camera and identify at least one region of interest within the full frame image. The one or more computing devices then configure the sampling camera to capture images of a sampling area containing the region of interest, wherein the sampling area consists of some, but not all, of a field of view of the sampling camera. Using a super-image resolution technique, the one or more computing devices create a high-resolution image of the region of interest from a plurality of images captured by the sampling camera.
