Abstract: A head-mounted display (HMD) device to be worn by a user in a physical environment (PE) is controlled. A 3D virtual environment (VE) is modeled to include a virtual controllable object subject to virtual control input. Motion of the position, head, and hands of the user is monitored in the PE, and a physical surface in the PE is detected. A virtual user interface (vUI) is placed in the VE relative to a virtual perspective of the user. The vUI includes an information display and at least one virtual touch control to produce the virtual control input in response to virtual manipulation of the virtual touch control. The vUI's placement is determined to coincide with the physical surface in the PE relative to the position of the user in the PE.

Abstract: Various systems and methods for real-time cascaded object recognition are described herein. A system for real-time cascaded object recognition comprises a processor; and a memory, including instructions, which when executed on the processor, cause the processor to perform the operations comprising: accessing image data at the system, the image data of an environment around the system, the image data is captured by a camera system; determining a set of regions in the image data, the set of regions including candidate objects; transmitting a subset of the image data corresponding to the set of regions to a remote server, the remote server to analyze the subset of the image data and detect an object in the subset of the image data; and receiving at the system from the remote server, an indication of the object detected in the subset of the image data.

Abstract: Embodiments of systems and techniques for user interface (UI) control are disclosed herein. In some embodiments, a UI control system may determine locations of landmarks on a body of a user of a computing system, determine a pointer based at least in part on the landmark locations, and identify a UI element of an UI of the computing system based at least in part on the pointer. Other embodiments may be described and/or claimed.
