  • Updating image in buffer via difference data
    Patent number: 8601184
    Abstract: Various embodiments related to a host computing device for rendering and sending image data to a peripheral device for display at the peripheral device. For example, one embodiment comprises a host computing device, the host computing device comprising a data storage subsystem and a logic subsystem. The host computing device further comprises instructions stored in the data storage subsystem and executable by the logic subsystem to output to the peripheral device a frame of image data representing a difference between a currently rendered image and an (N?1)-th previously rendered image, N being an integer and having a value of 3 or more.
    Type: Grant

  • Contextual control of dynamic input device
    Patent number: 8248373
    Abstract: A computing system includes one or more input-device user-interface runtime applications to dynamically display images on a dynamic input device. The one or more input-device user-interface runtime applications are executed in a currently active desktop. The computing system further includes a dominant application configured to execute in the currently active desktop. The dominant application is configured to specify an input-device user-interface runtime application corresponding to a current context of the dominant application. The specified input-device user-interface runtime application is configured to dynamically display virtual controls on the dynamic input device. The specified input-device user-interface runtime application is also configured to report activation of the virtual controls to the dominant application.
