Abstract

In general, the invention relates to a method for updating content on devices. The method includes detecting a local modification on a device, wherein the local modification is associated with a portion of a locally stored copy of a virtual canvas, wherein the portion of the locally stored copy of the virtual canvas is displayed on the device at a device-scale level, converting the local modification to a second local modification by scaling the local modification from the device-scale level to a system-scale level, updating, using the second local modification, the locally stored copy of the virtual canvas, generating a first update message comprising the second local modification, and transmitting the first update message to a workspace management system.

Claims

1. A method for updating content on devices, comprising:

detecting a local modification on a device, wherein the local modification is associated with a portion of a locally stored copy of a virtual canvas, wherein the portion of the locally stored copy of the virtual canvas is displayed on the device at a devicescale level;

converting the local modification to a second local modification by scaling the local modification from the device-scale level to a system-scale level;

updating, using the second local modification, the locally stored copy of the virtual canvas;

generating a first update message comprising the second local modification;

transmitting the first update message to a workspace management system;

receiving, from the workspace management system, a second update message comprising

a remote modification at the system-scale level;

updating, using the remote modification, the locally stored copy of the virtual canvas;

making a first determination that at least a portion of the remote modification is associated with the portion of the locally stored copy of the virtual canvas that is displayed on the device;

obtaining, based on the first determination, viewport information associated with the device, wherein the viewport information specifies at least the device-scale level;

converting, using the viewport information, at least the portion of the remote modification to a second remote modification by scaling at least the portion of the remote modification from the system-scale level to the device-scale level; and

displaying at least the second modification on the device.

2. The method of claim 1, wherein the device is one of a plurality of devices in the workspace.

3. The method of claim 2, wherein a source of the remote modification is a second device of the plurality of devices in the workspace.

4. The method of claim 1, wherein the device is one of a plurality of devices concurrently accessing the virtual canvas.

5. The method of claim 4, wherein a source of the remote modification is a second device of the plurality of devices.

6. The method of claim 1, wherein the system-scale level is greater than the device-scale level.

7. The method of claim 1, wherein the system-scale level is different than the device-scale level.

8. The method of claim 1, wherein updating the locally stored copy of the virtual canvas comprises storing an incremental update on the device, wherein the incremental update comprises the second local modification.

9. The method of claim 1, wherein the device is an e-flipchart apparatus.

10. The method of claim 1, wherein the workspace management system comprises a system copy of the virtual canvas.

11. A non-transitory computer readable medium comprising instructions, which when executed by a processor, performs a method, the method comprising:

detecting a local modification on a device, wherein the local modification is associated with a portion of a locally stored copy of a virtual canvas, wherein the portion of the locally stored copy of the virtual canvas is displayed on the device at a device-scale level;

converting the local modification to a second local modification by scaling the local modification from the device-scale level to a system-scale level;

updating, using the second local modification, the locally stored copy of the virtual canvas;

generating a first update message comprising the second local modification;

transmitting the first update message to a workspace management system;

receiving, from the workspace management system, a second update message comprising

a remote modification at the system-scale level;

updating, using the remote modification, the locally stored copy of the virtual canvas;

making a first determination that at least a portion of the remote modification is associated with the portion of the locally stored copy of the virtual canvas that is displayed on the device;

obtaining, based on the first determination, viewport information associated with the device, wherein the viewport information specifies at least the device-scale level;

converting, using the viewport information, at least the portion of the remote modification to a second remote modification by scaling at least the portion of the remote modification from the system-scale level to the device-scale level; and

displaying at least the second modification on the device.

12. The non-transitory computer readable medium of claim 11, wherein the device is one of a plurality of devices in the workspace.

13. The non-transitory computer readable medium of claim 12, wherein a source of the remote modification is a second device of the plurality of devices in the workspace.

14. The non-transitory computer readable medium of claim 11, wherein the device is one of a plurality of devices concurrently accessing the virtual canvas.

15. The non-transitory computer readable medium of claim 14, wherein a source of the remote modification is a second device of the plurality of devices.

16. The non-transitory computer readable medium of claim 11, wherein the system-scale level is greater than the device-scale level.

17. The non-transitory computer readable medium of claim 11, wherein the system-scale level is different than the device-scale level.

18. The non-transitory computer readable medium of claim 11, wherein updating the locally stored copy of the virtual canvas comprises storing an incremental update on the device, wherein the incremental update comprises the second local modification.

19. The non-transitory computer readable medium of claim 11, wherein the device is an e-flipchart apparatus.

20. The non-transitory computer readable medium of claim 11, wherein the workspace management system comprises a system copy of the virtual canvas.
