Abstract

The invention relates generally to improving content input between interactive input systems in a collaborative session. A mobile device having a processing structure; a transceiver communicating with a network using a communication protocol; and a computer-readable medium having instructions configures the processing structure to: receive a content object from an interactive device; perform recognition on the content object; determine a command code from the recognized content object; and modify another content object based at least in part on the command code.

First claim

What is claimed is:

1 . A mobile device comprising:
a processing structure; a transceiver communicating with a network using a communication protocol; and a computer-readable medium comprising instructions to configure the processing structure to:
receive a content object from an interactive device;
perform recognition on the content object;
determine a command code from the recognized content object; and
modify another content object based at least in part on the command code.

2 . The mobile device according to claim 1 further comprising instructions to configure the processing structure to: receive at least one command code parameter; and modify the another content object based in part on the at least one command code parameter.

3 . The mobile device according to claim 1 further comprising instructions to configure the processing structure to: add the command code to a content object modifier list.

4 . The mobile device according to claim 3 further comprising instructions to configure the processing structure to: modify at least a portion of a plurality of content objects based on the content object modifier list.

5 . The mobile device according to claim 3 further comprising instructions to configure the processing structure to: identify erasure of the content object associated with the command code; and remove the erased command code from the content object modifier list.

6 . The mobile device according to claim 1 wherein the command code comprises adjusting at least one content object attribute.

7 . The mobile device according to claim 2 wherein the at least one content object attribute comprises a colour.

8 . The mobile device according to claim 1 wherein the command code comprises a manipulation command code selected from at least one of scaling, rotation, and translation.

9 . The mobile device according to claim 8 further comprising instructions to configure the processing structure to: select the another content object following the command code to be manipulated.

10 . The mobile device according to claim 9 wherein a relative gesture specifies a manipulation quantity.

11 . The mobile device according to claim 9 wherein the selected content object is selected by at least one of circling, tapping, underlining, and connecting to the command code.

12 . The mobile device according to claim 1 wherein the command code comprises adjusting a canvas size.

13 . The mobile device according to claim 1 further comprising instructions to configure the processing structure to: initialize a recognition engine in response to the command code.

14 . The mobile device according to claim 13 wherein the recognition engine is selected from at least one of a shape recognition engine, a concept mapping engine, a chemical structure recognition engine, and a handwriting recognition engine.

15 . The mobile device according to claim 2 wherein the command code parameter comprises a uniform resource locator to a remote content object.

16 . The mobile device according to claim 1 wherein the interactive device comprises at least one of a capture board, an interactive whiteboard, an interactive flat screen display, or an interactive table.

17 . A computer-implemented method comprising:
receiving, at a mobile device, a content object from an interactive device over a communication channel; performing recognition on the content object; determining a command code from the recognized content object; and modifying another content object based at least in part on the command code.

18 . The computer-implemented method according to claim 17 further comprising receiving at least one command code parameter from the interactive device; and modifying the another content object based in part on the at least one command code parameter.

19 . The computer-implemented method according to claim 17 further comprising adding the command code to a content object modifier list.

20 . The computer-implemented method to claim 19 further comprising modifying at least a portion of a plurality of content objects based on the command codes on the content object modifier list.

21 . The computer-implemented method according to claim 19 further comprising identifying erasure of the command code; and removing the erased command code from the content object modifier list.

22 . The computer-implemented method according to claim 17 wherein the command code comprises adjusting at least one content object attribute.

23 . The computer-implemented method according to claim 20 wherein the at least one content object attribute comprises a colour.

24 . The computer-implemented method according to claim 17 wherein the command code comprises a manipulation command code selected from at least one of scaling, rotation, and translation.

25 . The computer-implemented method according to claim 24 further comprising selecting the another content object following the command code to be manipulated.

26 . The computer-implemented method according to claim 25 wherein a relative gesture specifies a manipulation quantity.

27 . The computer-implemented method according to claim 25 wherein the selected content object is selected by at least one of circling, tapping, underlining, and connecting to the command code.

28 . The computer-implemented method according to claim 17 wherein the command code comprises adjusting a canvas size.

29 . The computer-implemented method according to claim 17 further comprising initializing a recognition engine in response to the command code.

30 . The computer-implemented method according to claim 29 wherein the recognition engine is selected from at least one of a shape recognition engine, a concept mapping engine, a chemical structure recognition engine, and a handwriting recognition engine.

31 . The computer-implemented method according to claim 20 wherein the command code parameter comprises a uniform resource locator to a remote content object.

32 . The computer-implemented method according to claim 17 wherein the interactive device comprises at least one of a capture board, an interactive whiteboard, an interactive flat screen display, or an interactive table.

33 . An interactive device comprising:
a processing structure; an interactive surface; a transceiver communicating with a network using a communication protocol; and a computer-readable medium comprising instructions to configure the processing structure to:
provide a command code to a mobile device; and
provide command code parameters to the mobile device.
