Abstract

Illustrative embodiments disclose setting refresh rates for different portions of a shared screen in a sharing session. A processor sets an initial refresh rate for the sharing session. The processor selects a portion of the shared screen. The processor selects a refresh rate for the selected portion of the shared screen that is different from the initial refresh rate for the sharing session. The processor refreshes the selected portion based on the selected refresh rate and a portion not selected based on the initial refresh rate.

Claims

1. A computer-implemented method to set refresh rates for different portions of a shared screen in a sharing session, comprising:

setting, by a processor, an initial refresh rate for the sharing session, wherein the sharing session is between a display device that displays the shared screen and a remote client device that displays the shared screen;

selecting, by the processor, a portion of the shared screen;

selecting, by the processor, a refresh rate for the selected portion of the shared screen that is different from the initial refresh rate for the sharing session, wherein the selected refresh rate is a real number for how often the selected portion of the shared screen is refreshed each second, and wherein the selected refresh rate is selected from one of a first range including a high refresh rate, a medium refresh rate, and a low refresh rate, and wherein the low refresh rate is approximately 0.1 Hz, the high refresh rate is approximately 2 Hz, and the medium refresh rate is one of approximately 0.5 Hz and approximately 0.9Hz; and

refreshing, by the processor, the selected portion based on the selected refresh rate and a portion not selected based on the initial refresh rate.

2. The computer-implemented method of claim 1, wherein the selected portion comprises an area surrounding a pointer on the screen, wherein the area moves as the pointer moves on the screen.

3. The computer-implemented method of claim 2, wherein the area surrounding the pointer on the screen is a circle having a radius around a location of the pointer.

4. The computer-implemented method of claim 1, further comprising:

displaying, by the processor, an input on the shared screen for selecting the refresh rate.

5. The computer-implemented method of claim 1, wherein the selected portion comprises a first window and further comprising:

selecting, by the processor, a refresh rate that is high for a second window receiving an input from a pointer; and

updating, by the processor, the refresh rate for the first window to a refresh rate that is lower.

6. The computer-implemented method of claim 1, wherein the selected portion comprises a window and further comprising:

selecting, by the processor, a high priority rate for a window that is currently in use, wherein the window is currently selected and on top of any other window.

7. The computer-implemented method of claim 1, further comprising:

receiving, by the processor, an input from a pointer in the portion; and

selecting, by the processor, the portion receiving the input from the pointer.

8. The computer-implemented method of claim 1, further comprising:

receiving, by the processor, an input from a pointer in a set of portions indicating a location of the pointer;

tracking, by the processor, the location of the pointer in the set of portions over an interval of time;

determining, by the processor, the location of the pointer in each portion of the set of portions over the interval of time; and

selecting, by the processor, the portion of the set of portions where the pointer is located most frequently.

9. The computer-implemented method of claim 8, further comprising:

selecting, by the processor, a highest refresh rate for the portion of the set of portions where the pointer is located most frequently and a lowest refresh rate for a portion of the set of portions where the pointer is located least frequently.

10. The computer-implemented method of claim 1, wherein the refresh rate selected for the portions not selected is based on a type of application running in each portion.

11. The computer-implemented method of claim 1, wherein the first range further comprises a set of second ranges, each second range comprising a set of values for the high refresh rate, the medium refresh rate, and the low refresh rate respectively.
