Abstract

An approach is provided for automatically calculating and delivering proportional pointer locations during transition between multiple visual display devices (e.g., in regard to their characteristics, which may be heterogeneous, homogenous, or a mixture thereof). Specifically, the approaches described herein provide a solution for finding proportional locations of a pointer'"'"'s on-screen graphic as the pointer is being transitioned/moved between multiple display devices (e.g., controlled by a single computer or controller).

Claims

1. A computer-implemented method for proportional transition between multiple display devices, comprising:

determining an initial position of a pixel corresponding to a location of a pointer graphic on a first display device;

calculating a corresponding position of the pixel on a second display device as the pointer graphic is moved from the first display device to the second display device, wherein the corresponding position is calculated based on a proportion of a set of dimensions of the first display device to a set of dimensions of the second display device;

placing the pointer graphic at the corresponding position when the pointer graphic has been moved to the second display device, and

calculating, in response to a change in the location of the pointer graphic on the first display device, a new corresponding position of the pointer graphic on the second display device based on a distance between the initial position and a new position on the first display device and the proportion.

2. The computer-implemented method of claim 1, the initial position of the pixel being along a border of the first display device, and the corresponding position of the pixel being along a border of the second display device.

3. The computer-implemented method of claim 2, further comprising determining a percentage along the border of the first display from an endpoint of the border of the first display, the calculating comprising applying the percentage to the border of the second display device to calculate the corresponding position.

4. The computer-implemented method of claim 3, the calculating comprising an interpolation between the border of the first display device and the border of the second display device.

5. The computer-implemented method of claim 1, the first display device and the second display device being operated from a common computer or a common controller.

6. The computer-implemented method of claim 1, the first display device and the second display device having different sizes, orientations, or aspect ratios.

7. A system for proportional transition between multiple display devices, comprising:

a bus;

a processor coupled to the bus; and

a memory medium coupled to or accessed via the bus, the memory medium comprising instructions to;

determine an initial position of a pixel corresponding to a location of a pointer graphic on a first display device;

calculate a corresponding position of the pixel on a second display device as the pointer graphic is moved from the first display device to the second display device, wherein the corresponding position is calculated based on a proportion of a set of dimensions of the first display device to a set of dimensions of the second display device;

place the pointer graphic at the corresponding position when the pointer graphic has been moved to the second display device, and

calculate, in response to a change in the location of the pointer graphic on the first display device, a new corresponding position of the pointer graphic on the second display device based on a distance between the initial position and a new position on the first display device and the proportion.

8. The system of claim 7, the initial position of the pixel being along a border of the first display device, and the corresponding position of the pixel being along a border of the second display device.

9. The system of claim 8, the memory medium further comprising instructions to determine a percentage along the border of the first display from an endpoint of the border of the first display, the calculation comprising applying the percentage to the border of the second display device to calculate the corresponding position.

10. The system of claim 9, the calculation comprising an interpolation between the border of the first display device and the border of the second display device.

11. The system of claim 7, the first display device and the second display device being operated from a common computer or a common controller.

12. The system of claim 7, the first display device and the second display device having at least one of the following:

different sizes, orientations, or aspect ratios.

13. A computer program product for proportional transition between multiple display devices, the computer program product comprising a computer readable storage media, and program instructions stored on the computer readable storage media, to:

determine an initial position of a pixel corresponding to a location of a pointer graphic on a first display device;

calculate a corresponding position of the pixel on a second display device as the pointer graphic is moved from the first display device to the second display device, wherein the corresponding position is calculated based on a proportion of a set of dimensions of the first display device to a set of dimensions of the second display device;

place the pointer graphic at the corresponding position when the pointer graphic has been moved to the second display device, and

calculate, in response to a change in the location of the pointer graphic on the first display device, a new corresponding position of the pointer graphic on the second display device based on a distance between the initial position and a new position on the first display device and the proportion.

14. The computer program product of claim 13, the initial position of the pixel being along a border of the first display device, and the corresponding position of the pixel being along a border of the second display device.

15. The computer program product of claim 14, further comprising program instructions stored on the computer readable storage media to determine a percentage along the border of the first display from an endpoint of the border of the first display, the calculation comprising applying the percentage to the border of the second display device to calculate the corresponding position.

16. The computer program product of claim 15, the calculation comprising an interpolation between the border of the first display device and the border of the second display device.

17. The computer program product of claim 13, the first display device and the second display device being operated from a common computer or a common controller.

18. The system of claim 13, the first display device and the second display device having at least one of the following:

different sizes, orientations, or aspect ratios.
