An exemplary eye tracking system for a NED device includes sensors that are directed toward and angularly offset from a user's eyes in a manner that causes circular features (e.g., irises and/or pupils) of the user's eyes to appear elliptical within sensor planes of the individual sensors.

The eye tracking systems and methods disclosed herein exploit these principles to track movements of the user's eyes with a higher degree of accuracy than conventional eye tracking systems.

Abstract: One embodiment of the present invention includes a parallel processing unit (PPU) that performs pixel shading at variable granularities. For effects that vary at a low frequency across a pixel block, a coarse shading unit performs the associated shading operations on a subset of the pixels in the pixel block. By contrast, for effects that vary at a high frequency across the pixel block, fine shading units perform the associated shading operations on each pixel in the pixel block. Because the PPU implements coarse shading units and fine shading units, the PPU may tune the shading rate per-effect based on the frequency of variation across each pixel group. By contrast, conventional PPUs typically compute all effects per-pixel, performing redundant shading operations for low frequency effects. Consequently, to produce similar image quality, the PPU consumes less power and increases the rendering frame rate compared to a conventional PPU.

In implementations, systems can refine initial predictive information to reflect an observed condition based on comparison of the observed with an analysis of sets of collected observed information.

First and second spatial mapping data is accessed, where both the first and second spatial mapping data overlap in that they both, at least partially, describe the same portion of an environment three-dimensionally. A determination is made as to whether the second spatial mapping data is to augment the first spatial mapping data. If so, then the second spatial mapping data is used to augment the first spatial mapping data. Otherwise, the second spatial mapping data is not used to augment the first spatial mapping data. These determinations may be based, at least in part, on determined quality levels of the first and second spatial mapping data.

Abstract: A content manipulation application provides a graphical interface for editing graphical content. The graphical interface includes first and second control elements for performing first and second manipulations of the graphical content. If the first control element is selected, the content management application switches the graphical interface to a trackpad mode. The trackpad mode disables the second control element and thereby prevents the second control element from performing the second manipulation. While the graphical interface is in the trackpad mode, the content management application receives an input in an input area that lacks the first control element and performs the first manipulation of the graphical content responsive to receiving the input. Subsequent to the first manipulation being performed, the graphical interface is switched out of the trackpad mode, thereby enabling the second control element to perform the second manipulation.

Abstract: A computer-implemented technique is described herein for generating a digital representation of real-world surfaces in an environment. The technique involves receiving sensor data captured by one or more depth-sensing devices. The technique then provides a low-detail (LD) representation of surfaces in the physical environment based on the sensor data; that LD representation describes one or more planes in the physical environment. The technique then generates a high-detail (HD) representation of the surfaces based on the sensor data and the LD representation. Finally, the technique provides an output result based on the LD representation and/or the HD representation. According to one illustrative aspect, the technique produces the HD representation such that it is non-duplicative of information that is already present in the LD representation. The technique performs this task by identifying and excluding HD information that is already adequately represented by the LD representation.
