6. The method of claim 1 , wherein packaging the updated screen data further includes,

retrieving current screen data associated with the screen currently being rendered at the client device from a local buffer at the client;

intercepting, by the client device, the updated screen data transmitted by the host computer service to the display device;

retrieving, at the client device, data related to the transition graphics for the desired gesture; and

packaging the updated screen data with the current screen data and the transition graphics data related to the desired gesture to generate the packaged screen data, the packaged screen data returned to the display device for rendering, wherein the transition graphics data provides a transition from the current screen data to the updated screen data when rendered at the display device.

7. A processor-implemented method for enabling locally generated gestures and transition graphics to interact with virtualized host computer service, comprising:

receiving a selection command at a display device of a client device, wherein the selection command involves a user interaction with the display device and is issued to request an update to current screen data rendered at the display device;

transmitting the selection command to the host computer service for processing;

receiving updated screen data, by the client device from the host computer service, for the screen data rendered at the display device, after the selection command is transmitted;

receiving a desired gesture to be rendered with the updated screen data from the host computer service, wherein the desired gesture corresponds to the updated screen data transmitted by the host computer service device and dictates adjustment to be made at the display device during rendering of the updated screen data, and wherein the transmitted selection command is mapped to the desired gesture in a mapping table available to the host computer service;

identifying transition graphics based on the selection command and to be included so as to provide a screen transition effect for the desired gesture when rendering updated screen data;

packaging, at the client device responsive to receiving the updated screen data, the updated screen data received from the host computer service with transition graphics generated at the client device for the desired gesture received from the host computer service to generated packaged screen data, the transition graphics embedded between a currently rendered screen data and updated screen data so as to provide the screen transition effect that generates a visual response between the currently rendered screen data and the updated screen data; and

returning the packaged screen data to the display device for rendering, in response to the selection command, the packaged screen data rendering desired gesture related data as transitions, using transition graphics generated at the client device for the desired gesture, during the rendering of the updated screen data.

8. The method of claim 7 , wherein the updated screen data is received as frame buffer data.

9. The method of claim 7 , further comprising:

querying the mapping table using the selection command received from the client device; and

selecting the desired gesture mapped to the selection command from the mapping table, the desired gesture identifying data related to the transition graphics to be included during rendering of the screen update.

10. The method of claim 7 , wherein packaging the updated screen data further includes,

intercepting, by the client device, the updated screen data transmitted by the host computer service to the display device;

retrieving, at the client device, data related to the transition graphics for the desired gesture; and

packaging the updated screen data with the transition graphics data related to the desired gesture to generate the packaged screen data, wherein the transition graphics data provides a transition during rendering of the updated screen data at the client device.

11. The method of claim 10 , further includes,

retrieving current screen data related to the screen currently being rendered at the client device from a local buffer at the client; and

integrating the current screen data with the packaged updated screen data, the integration providing the desired transition during rendering of the updated screen data at the display device.

12. A system for enabling locally generated gestures and transition graphics to interact with virtualized host computer service, comprising:

a client device having a display device for rendering screen data, the client device executing a client-side application, the client-side application configured to,

interpret a control command obtained from the display device to identify a desired gesture associated with the control command, wherein the control command involves a user interaction with the display device, is mapped to the desired gesture in a mapping table, and controls screen data rendered at the display device;

identify transition graphics based on the control command and to be included so as to provide a screen transition effect for the desired gesture when rendering updated screen data;
