Abstract

Systems and methods are described for using a mobile phone to control a computing device. In one implementation, a communication protocol stack is established that includes a wireless layer, such as a Bluetooth stack, a communication layer that multiplexes the wireless layer into virtual channels, and an application adaptation layer by which the mobile phone controls and previews content from each of multiple applications on the computing device. The communication protocol stack dynamically maps mobile phone keys to computer keyboard messages for controlling the applications on the computing device. A data packet structure is established for communications between the mobile phone and the computing device via the communication protocol stack.

Claims

1. A method, comprising:

establishing a communication protocol between a mobile phone and a computing device; and

controlling the computing device via the mobile phone using the communication protocol.

2. The method as recited in claim 1, wherein controlling the computing device includes controlling multiple applications on the computing device via a user interface of the mobile phone.

3. The method as recited in claim 1, wherein controlling the computing device includes browsing storage media, subdirectory structures, and individual files on the computing device via at least one user interface of the mobile phone.

4. The method as recited in claim 1, wherein controlling the computing device includes previewing image content of an application on the computing device via at least one user interface of the mobile phone.

5. The method as recited in claim 1, wherein establishing a communication protocol includes establishing a protocol stack, including:

establishing a physical layer, wherein the physical layer comprises a wireless link;

establishing a communication layer for communicating with multiple applications on the computing device via corresponding virtual channels of the communication layer; and

establishing an application adaptation layer to control the multiple applications via the virtual channels.

6. The method as recited in claim 5, wherein establishing a communication layer includes multiplexing the wireless link to create the multiple virtual channels.

7. The method as recited in claim 5, wherein the wireless link comprises a BLUETOOTH stack.

8. The method as recited in claim 5, wherein establishing the communication layer includes establishing a data packet structure for sending commands and acknowledgements between the mobile phone and the multiple applications on the computing device via the multiple virtual channels.

9. The method as recited in claim 5, wherein establishing a data packet structure includes establishing a packet structure that includes at least a virtual channel identifier field, a data type field, and a payload field, wherein the data type field informs at least one of the multiple applications in the computing device of a data type of data in the payload field.

10. The method as recited in claim 5, wherein establishing a communication layer includes, for each application on the computing device to be controlled by the mobile phone, dynamically mapping a user interface of the mobile phone to application control messages of the computing device.

11. The method as recited in claim 10, wherein the user interface of the mobile phone is selected from the group of user interfaces consisting of:

keypad keys, a switch, a touch pad, a touch screen, a stylus pen, a stylus pad, a command interface, a camera, a speech interface, a speech reorganizing module, a mouse, a selection wheel, navigation keys, and arrow keys.

12. The method as recited in claim 1, wherein controlling the computing device via the mobile phone includes controlling an application on the computing device, the application selected from the group of applications consisting of:

a graphics presentation application, a multimedia application, and a file browsing application.

13. The method as recite in claim 1, wherein controlling the computing device via the mobile phone includes previewing, on the mobile phone, slides of a graphics presentation program running on the computing device.

14. The method as recite in claim 1, wherein controlling the computing device via the mobile phone includes monitoring, on the mobile phone, a television channel of a multimedia application running on the computing device.

15. The method as recite in claim 1, wherein controlling the computing device via the mobile phone includes automatically authenticating a user of the mobile phone on the computing device via a phone number of the mobile phone.

16. The method as recited in claim 1, wherein controlling the computing device via the mobile phone includes managing digital rights of a content on the computing device using a telephone number of the mobile phone as permission to view the content.

17. A system, comprising:

a computing device;

a mobile phone communicatively coupled with the computing device;

a communication protocol stack in each of the computing device and the mobile phone, wherein the mobile phone controls each of multiple applications on the computing device via virtual channels of the communication protocol stack.

18. The system as recited in claim 17, wherein the communication protocol stack includes at least one communication layer and an application adaptation layer, the application adaptation layer including a variable number of application control modules, each application control module to control a behavior of an application on the computing device via one of the virtual channels of the communication layer.

19. The system as recited in claim 17, wherein the communication protocol stack includes a user interface mapping manager to create, for each application to be controlled on the computing device, a mapping between a user interface of the mobile phone and application control messages of the computing device.

20. A system, comprising:

means for communicating control data between a mobile phone and a computing device;

means for controlling each of multiple applications on the computing device via the control data from the mobile phone.
