  • Patent number: 11227558
    Abstract: Systems and methods to compensate for color fringe visual artifacts due at least in part to subpixel locations on an electronic display are provided. An electronic device may include subpixel layout compensation circuitry (SLCC) and an electronic display. The SLCC may receive first image data and an indication of spatial positions of subpixels that make up pixels of an electronic display. The SLCC may generate second image data based at least in part on the first image data and the indication of the spatial positions of the subpixels. The second image data may reduce or eliminate a color fringe artifact that would otherwise occur without compensation.

  • Patent number: 11175735
    Abstract: Systems and techniques are disclosed that provide application analytics data that combines gaze data and selection data. An application is configured with UI items that are grouped for analytics tracking and configured to track gazes and selections. When the application is used, the user's eye movements and pauses are monitored to identify when the user gazes upon a UI item. In one embodiment, based on determining that a gaze location is within a bounding box corresponding to a first UI item, the system determines that the gaze corresponded to the first UI item. The system also identifies subsequent selections of other UI items in the group. After a selection of a second UI item in the group is received, application analytics data is provided that identifies the gaze corresponding to the first UI item occurring prior to the selection of the second UI item.

  • Patent number: 11150758
    Abstract: A method includes obtaining sensor coordinates and pressure values corresponding to the sensor coordinates; mapping, using a first mapping method, a first set of the sensor coordinates to first display screen coordinates; determining that a first one of the pressure values is greater than or equal to a threshold pressure value; determining that a second one of the pressure values is less than the threshold pressure value, after determining that the first one of the pressure values is greater than or equal to the threshold pressure value; in response to the determining that the second one of the pressure values is less than the threshold pressure value, mapping, using a second mapping method, a second set of the sensor coordinates to second display screen coordinates; and outputting the first display screen coordinates and the second display screen coordinates. Accordingly, an operator can easily switch the mapping to the second method.
