Abstract

The present invention relates to a method and system for adapting communication between interactive input systems. A mobile device has 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. The mobile device is configured to retrieve a pairing uniform resource locator (URL) from an interactive device and convert the pairing URL into a network address. A connection is established to an interactive device located at the network address using the transceiver. The mobile device queries the interactive device for device information and authenticates with the interactive device. One or more content objects are retrieved from the interactive device. The mobile device optimizes the communication protocol through negotiation of a protocol level based in part on the device information.

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:
retrieve a pairing uniform resource locator (URL) from an interactive device;
convert the pairing URL into a network address;
establish a connection to the interactive device located at the network address using the transceiver;
query for device information of the interactive device over the connection;
authenticate the mobile device with the interactive device; and
receive at least one content object from the interactive device.

2 . The mobile device according to claim 1 wherein the computer-readable medium further comprises instructions to configure the processing structure to initiate an optimization of the communication protocol.

3 . The mobile device according to claim 2 wherein the optimization of the communication protocol comprises negotiation of a protocol level based in part on the device information.

4 . The mobile device according to claim 3 wherein the protocol level comprises a set of protocol rules.

5 . The mobile device according to claim 4 wherein at least one of the protocol rules comprises synchronizing a timer with a reference clock; the timer stored within the computer-readable medium and serviced by the processing structure.

6 . The mobile device according to claim 4 wherein the computer-readable medium further comprises instructions to read a unique identifier for the mobile device.

7 . The mobile device according to claim 6 wherein at least one of the protocol rules comprises negotiating an alias for the unique identifier.

8 . The mobile device according to claim 4 wherein at least one of the protocol rules comprises adjusting a resolution of a coordinate space.

9 . The mobile device according to claim 8 wherein the resolution comprises at least one of an absolute coordinate resolution, a relative coordinate resolution, or both the absolute and the relative coordinate resolution.

10 . The mobile device according to claim 8 wherein the coordinate space corresponds to a canvas size comprising a diagonal of less than about 7.5191 m for a 16:9 aspect ratio.

11 . The mobile device according to claim 9 wherein the absolute coordinate resolution is between about 0.005 mm/bit and about 0.1 mm/bit.

12 . The mobile device according to claim 9 wherein the relative coordinate resolution is between about 0.005 mm/bit and about 0.1 mm/bit.

13 . The mobile device according to claim 4 wherein the at least one content object comprises at least one of a digital ink object, a shape object, a curve object, a vector object, an audio object, an image object, a text object, or a video object.

14 . The mobile device according to claim 13 wherein at least one of the protocol rules comprises adjusting at least one digital ink attribute of the digital ink object.

15 . The mobile device according to claim 14 wherein the at least one digital ink attribute comprises a pointer resolution of 0.5 mm/bit.

16 . The mobile device according to claim 14 wherein the at least one digital ink attribute comprises a stroke colour.

17 . The mobile device according to claim 14 wherein the at least one digital ink attribute comprises a set of unique pointer identifiers.

18 . The mobile device according to claim 5 wherein each content object has a unique content object identifier.

19 . The mobile device according to claim 18 wherein each content object has a creation timestamp retrieved from the timer.

20 . The mobile device according to claim 1 wherein the computer-readable medium further comprises instructions to configure the processing structure to receive remote content objects from remote interactive devices.

21 . 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.

22 . The mobile device according to claim 1 further comprising an image sensor to capture an optically recognizable image.

23 . The mobile device according to claim 22 further comprising instructions to decode the optically recognizable image to retrieve the pairing uniform resource locator.

24 . The mobile device according to claim 1 further comprising a near field radio frequency reader to receive the pairing URL.

25 . A method of establishing a connection between a mobile device and an interactive device comprising:
retrieving a pairing uniform resource locator (URL) from the interactive device; converting, using a processing structure, the pairing URL into a network address; establishing the connection to the interactive device located at the network address using a transceiver; querying for device information of the interactive device over the connection; authenticating the mobile device with the interactive device; and receiving at least one content object from the interactive device.

26 . The method according to claim 25 further comprising initiating an optimization of a communication protocol by negotiating a protocol level based in part on the device information.

27 . The method according to claim 26 further comprising altering a set of protocol rules based on the protocol level.

28 . The method according to claim 27 wherein at least one of the protocol rules comprises synchronizing a timer with a reference clock.

29 . The method according to claim 27 further comprising retrieving by the processing structure a unique identifier for the mobile device.

30 . The method according to claim 27 further comprising adjusting a resolution of a coordinate space.

31 . The method according to claim 30 wherein the resolution comprises at least one of an absolute coordinate resolution, a relative coordinate resolution, or both the absolute and the relative coordinate resolution.

32 . The method according to claim 31 wherein the absolute coordinate resolution is between about 0.005 mm/bit and about 0.1 mm/bit.

33 . The method according to claim 31 wherein the relative coordinate resolution is between about 0.005 mm/bit and about 0.1 mm/bit.

34 . The method according to claim 25 wherein the at least one content object comprises at least one of digital ink object, a shape object, a curve object, a vector object, an audio object, an image object, a text object, or a video object.

35 . The method according to claim 34 further comprising adjusting at least one digital ink attribute of the digital ink object.

36 . The method according to claim 35 wherein the at least one digital ink attribute comprises a stroke colour.

37 . The method according to claim 35 wherein the at least one digital ink attribute comprises a set of unique pointer identifiers.

38 . The method according to claim 28 further comprising assigning at least a portion of the content objects with a unique content object identifier.

39 . The method according to claim 38 further comprising appending at least a portion of the
