Abstract

A “follow-me” utility runs on each of a plurality devices a person may typically use. This utility monitors applications running on a device and intelligently saves the state of tasks a user is performing. When the follow-me utility detects that the user has initialized another device having the follow-me utility and connectivity to the original device, the utility automatically and transparently creates an environment on the new device so that the user may continue the task at the same point as when he or she last performed the task on the original device. When the user continues a task or starts a new task, the follow-me utility automatically and transparently updates files and task states on any devices having the follow-me utility and connectivity. The follow-me utility may make intelligent task migration decisions based on conditions such as network bandwidth, security policy, location, and device capability.

Claims

1. A method for migrating a task between devices, the method comprising:

identifying a task currently executing on a first device;

saving task state information associated with the task on the first device;

responsive to a second device establishing a communicative coupling with the first device, automatically transferring the task state information to the second device; and

automatically initializing the task on the second device according to the task state information so that the task can resume execution at a point at which the task was transferred to the second device.

2. The method of claim 1, wherein the task state information comprises at least one of a document, cursor location, page being viewed, window location, window size, insert/overwrite mode, or selected text.

3. The method of claim 1, wherein a communicative coupling comprises a wired network connection, a wireless network connection, a wired direct connection, a universal serial bus connection, an Ethernet connection via a crossover cable, or a wireless direct connection.

4. The method of claim 1, wherein the communicative coupling comprises a communication session that includes a security measure to ensure that the task state information is not distributed to unauthorized devices.

5. The method of claim 1, wherein the task state information comprises a first document, the method further comprising:

responsive to a third device establishing a communicative coupling with the first device, automatically receiving a second document and associated task state information from the third device.

6. The method of claim 5, further comprising:

initializing the second document on the first device based on a device profile associated with the first device.

7. The method of claim 6, wherein the device profile comprises at least one of screen resolution, amount of memory, processor speed, application information, or security level.

8. The method of claim 6, wherein initializing the second document comprises:

identifying a first application in which the document was created on the third device;

determining that the first device does not have the first application;

identifying a second application on the first device that is compatible with the first document; and

opening the document using the second application.

9. The method of claim 6, wherein initializing the second document comprises:

identifying a first application in which the document was created on the third device;

determining that the first device does not have the first application; and

provisioning the first application from a provisioning service.

10. The method of claim 6, wherein initializing the second document comprises:

identifying a first application in which the document was created on the third device;

determining that the first device does not have the first application

identifying a second application that is compatible with the first document; and

determining that the first device does not have the second application; and

provisioning the second application from a provisioning service.

11. The method of claim 5, further comprising:

forwarding the second document and associated task state information to a fourth device without the third device and fourth device having a communicative coupling therebetween.

12. A system within a first device, comprising:

a processor in the first device; and

a memory in the first device, wherein the memory comprises instructions, which when executed by the processor, cause the processor to;

identify a task currently executing on the first device;

save task state information associated with the task on the first device; and

responsive to a second device establishing a communicative coupling with the first device, automatically transfer the task state information to the second device such that the second device automatically initializes the task on the second device according to the task state information so that the task can resume execution at a point at which the task was transferred to the second device.

13. The system of claim 12, wherein the task state information comprises at least one of a document, cursor location, page being viewed, window location, window size, insert overwrite mode, or selected text.

14. The system of claim 12, wherein a communicative coupling comprises a wired network connection, a wireless network connection, a wired direct connection, a universal serial bus connection, an Ethernet connection via a crossover cable, or a wireless direct connection.

15. The system of claim 12, wherein the communicative coupling comprises a communication session that includes a security measure to ensure that the task state information is not distributed to unauthorized devices.

16. The system of claim 12, wherein the task state information comprises a first document, wherein the instructions further cause the processor to:

responsive to a third device establishing a communicative coupling with the first device, automatically receive a second document and associated task state information from the third device.

17. The system of claim 16, wherein the instructions further cause the processor to:

initialize the second document on the first device based on a device profile associated with the first device.

18. A computer program product comprising a computer useable medium having a computer readable program, wherein the computer readable program, when executed on a computing device, causes the computing device to:

identify a task on the first device;

save task state information associated with the task on the first device; and

responsive to a second device establishing a communicative coupling with the first device, automatically transfer the task state information to the second device such that the second device automatically initializes the task on the second device according to the task state information so that the task can resume execution at a point at which the task was transferred to the second device.

19. The computer program product of claim 18, wherein the computer readable program comprises instructions that are stored in a computer readable storage medium in a data processing system, and wherein the instructions were downloaded over a network from a remote data processing system.

20. The computer program product of claim 18, wherein the computer readable program comprises instructions that are stored in a computer readable storage medium in a server data processing system, and wherein the instructions are downloaded over a network to a remote data processing system for use in a computer readable storage medium with the remote data processing system.
