Abstract: A system includes a computing device that includes a memory and a processor configured to execute instructions to perform a method that includes receiving multiple representations of one or more expressions of an object. Each representation includes position information attained from one or more images of the object. The method also includes producing an animation model from one or more groups of controls that respectively define each of the one or more expressions of the object as provided by the multiple representations. Each control of each group of controls has an adjustable value that defines the geometry of at least one shape of a portion of the respective expression of the object. Producing the animation model includes producing one or more corrective shapes if the animation model is incapable of accurately presenting the one or more expressions of the object as provided by the multiple representations.

The identification module determines tag information associated with the individual using the received identification signal and displays, to a user, the tag information overlayed on the image of the individual.

Abstract: An optical evaluation workstation evaluates quality metrics (e.g., optical contrast) of optical elements of a HMD. The workstation includes a test pattern, an optical element feed assembly, a light source, a camera and a control module. The light source backlights the test pattern with diffuse light. The optical element feed assembly receives an optical element of a HMD and places the optical element at a first distance from the test pattern corresponding to a distance between the optics block in the HMD and an exit pupil of the HMD. The camera images the test pattern through the optical element and the camera is positioned at a second distance from the test pattern corresponding to a distance between the exit pupil and an electronic display in the HMD. The control module generates a test report for presentation to a user based on the evaluation of the optical element.

Abstract: An optical see-through (OST) head-mounted display (HMD) uses a calibration matrix having a fixed sub-set of adjustable parameters within all its parameters. Initial values for the calibration matrix are based on a model head. A predefined set of incremental adjustment values is provided for each adjustable parameter. During calibration, the calibration matrix is cycled through its predefined incremental parameter changes, and a virtual object is projected for each incremental change. The resultant projected virtual object is aligned to a reference real object, and the projected virtual object having the best alignment is identified. The setting values of the calibration matrix that resulted in the best aligned virtual object are deemed the final calibration matrix to be used with the OST HMD.

Abstract: Source image content is adapted to a target display. Target image content associated with the target display is provided. A histogram is computed for the target image content. A prominent feature present in the target histogram is determined. A histogram is computed for the source image content. The source content histogram is manipulated to reflect the determined target histogram prominent feature(s). Adapted source image content is generated based on the manipulated source histograms(s). Another prominent feature present in the target histogram is determined. The source histogram is further manipulated to reflect the other prominent determined target histogram features. Further adapted source image content is generated based on the further manipulated source histogram if the adapted source image content has insufficient image quality and perceptual color characteristics.

Abstract: A subsystem configured to encode an RGBA8 data stream assembles sequences of four-byte groups from the data stream. The subsystem decorrelates the red and blue channels, and computes a difference between each four-byte group and an anchor value. The anchor is encoded at full value. The subsystem then assigns each group a five-bit header based on the number and location of non-zero bytes and on the data content of the non-zero bytes within the group. The subsystem favors zero valued bytes. Thus, when a group includes only zero valued bytes, the header is sufficient to encode the group; no data bits are necessary. Further, two successive groups of zero-valued bytes may be encoded as a single header with no data bits, achieving further data reduction. Finally, the subsystem concatenates all the headers with associated data to yield the source data stream compressed to some ratio, e.g. four-to-one.

Abstract: The invention relates to a method for masking an item among a plurality of items displayed on a touchscreen terminal, the method being such that it has, following an action (300) by a user, steps of display (301) of a masking symbol associated with an item at a first location; of detection (302) of contact with the screen on a non-masked item; of continuous movement (303) of the masking symbol on the item in correlation with movement of the contact detected on the screen and of masking of that portion of the item that is situated between the masking symbol and the first location; and of masking (304) of the whole of the item when the masking symbol is at a second location and the contact is no longer detected. The invention likewise relates to a device and a terminal that implement this method.

Abstract: One embodiment of the present invention sets forth a method for pre-computing Z-values using an IGPU and, subsequently, conveying these Z-values to a DGPU. The graphics driver partitions the display into rectangular M-by-N tiles of pixels. For each tile, the graphics driver generates a quad geometry that encompasses the corresponding pixels. For each image frame, the graphics driver configures the IGPU to generate and down-sample a Z-buffer, creating a coarse Z-texture that contains a Z-value for each tile. The graphics driver transfers the coarse Z-texture to the system memory and configures the DGPU to apply the coarse Z-texture to the quad geometries, thereby generating a coarse Z-buffer in which the M-by-N pixels included in each tile are assigned the Z-value for the particular tile. Among other things, this technique enables the IGPU to pre-compute Z-values for the DGPU without straining the system memory bandwidth or defeating the Z-buffer compression techniques used by the DGPU.

Abstract: Unlike the GPU's FlexRender, a browser engine can intercept rendering at a higher level in the software stack, and because of the simpler nature of the browser tiles that need to be rendered, a browser engine can instruct the GPU to perform composition via traditional tiled-rendering or via direct rendering, where an output of the GPU is written to slower system memory, rather than the faster GPU memory.

Abstract: A computing device outputs a chart matrix defined by associating a first data dimension with a row edge and a second data dimension with a column edge. Members of the first data dimension are displayed as row headers of the chart matrix, and members of the second data dimension are displayed as column headers of the chart matrix. The device outputs charts in matrix cells of the chart matrix defined by intersections of rows defined by the row edge and columns defined by the column edge. The computing device provides user options to perform a drill operation on a selected member displayed in the chart matrix. The computing device outputs, in response to the user input to perform the drill operation, a modified chart matrix displaying related members in at least one of the charts, wherein the related members are related by one hierarchical level from the selected member.
