Abstract: A method for calibrating a wearable device includes displaying an image with a plurality of pixels for each of three primary colors using the wearable device, and determining RGB and XYZ values for each of the plurality of pixels. The method includes selecting a subset of the plurality of pixels to form a group of grid points, and dividing the image into a group of tile regions, with each tile region including a grid point. Grid XYZ values are determined for each grid point, based on averaging XYZ values of all pixels in a corresponding tile region, and a grid RGB-to-XYZ conversion matrix is determined for each grid point. The method also includes determining a correction matrix for each grid point by multiplying an inverse of the grid RGB-to-XYZ conversion matrix for the grid with an sRGB-to-XYZ conversion matrix.

Abstract: Examples described herein relate to a software and hardware optimization that manages scenarios where a write operation to a register is less than an entirety of the register. A compiler detects instructions that make partial writes to the same register, groups such instructions, and provides hints to hardware of the partial write. The execution unit combines the output data for grouped instructions and updates the destination register as single write instead of multiple separate partial writes.

Abstract: A method of operating a tile-based graphics processor that can use one of plural different rendering tile sizes is disclosed. The tile-based graphics processor includes a rasteriser that can rasterise primitives in a hierarchical manner. A patch size at which to begin the hierarchical testing of primitives in the rasteriser is selected based on the rendering tile size that is to be used. This can reduce the overall number of tests performed to rasterise primitives without impacting the correct functioning of the hierarchical rasterisation process.

Abstract: A GPU is generally configured to detect changes in the rate of frame generation that can result from, for example, changes in the complexity of the frames being generated. In response to detecting the change in the rate of frame generation, the GPU identifies a corresponding change in the refresh rate that would be required to fully synchronize the refresh rate with the rate of frame generation. If the change in the refresh rate falls outside the boundaries of a specified or dynamically generated window, the GPU limits the change in refresh rate to the corresponding boundary.

The control unit is further configured to send signals to change a display state of the second indicator according to the second input and initiate an operation to be performed based on a combination of the first and second inputs.

Abstract: A graphics processing unit having multiple groups of processor cores for rendering graphics data for allocated tiles and outputting the processed data to regions of a memory resource. Scheduling logic allocates sets of tiles to the groups of processor cores to perform a first render, and at a time when at least one of the groups has not completed processing its allocated sets of one or more tiles as part of the first render, allocates at least one set of tiles for a second render to one of the other groups of processor cores for processing. Progress indication logic indicates progress of the first render, indicating regions of the memory resource for which processing for the first render has been completed. Progress check logic checks the progress indication in response to a request for access to a region of the memory resource as part of the second render and enables access that region of the resource in response to an indication that processing for the first render has been completed for that region.

Abstract: A method and system for objectively tracking and analyzing the social and emotional activity of a patient using an augmented reality computing device is provided. A patient is permitted to manually manipulate a target object in the physical world while viewing an augmented version showing a unique animated character representing either an abstract language, emotions, or social skills, depending on the module. The present system tracks and records the active face and the time spent on the active face, where the active face is the face upon which the patient's focus is automatically estimated, through calculation, to be trained upon. An observer views the session, the data recorded, and an automatically generated graphical representation of the data, which permits the observer to speak to patient regarding the character or scene rendered on the face which is determined to be the active face, helping the student engage in the session.

Abstract: Managing data for transportation is provided via storing data at a host device, where the data is processed and encapsulated into transport units having a maximum size. The data is divided and processed into processed portions of varying size. The processed portions are stored sequentially into an output buffer to form the transport units, with a potential start field space left between each processed portion. A set of processed portions stored in the output buffer is determined based on sizes of the processed portions, the set starting after a previous actual start field where the set has a size less than the maximum size and a potential start field space after a last of the processed portions in the set is replaced by an actual start field to define the set. Sets of processed portions delimited by actual start fields may then be output.

Abstract: A photo filter (e.g., artistic) light field effect system comprises an eyewear device that includes a frame, a temple connected to a lateral side of the frame, and a depth-capturing camera. Execution of programming by a processor configures the photo filter light field effect system to apply a photo filter selection to: (i) a left raw image or a left processed image to create a left photo filter image, and (ii) a right raw image or a right processed image to create a right photo filter image. The photo filter light field effect system generates, a photo filter light field effect image with an appearance of a spatial rotation or movement, by blending together the left photo filter image and the right photo filter image based on a left image disparity map and a right image disparity map.
