Abstract

A portable device that allows accessing the Internet and World Wide Web wirelessly through a cellular telephone. A host computer, which may also be a Web server, translates and compresses into bitmap or raster images the information received from the Internet. The compressed images are sent to the portable device for decompression and display. The portable device accepts pointing and clicking to links to other pages. Commands entered by the user at the portable device are sent to the host computer for execution via a virtual browser to generate a new page, which is then rasterized, compressed and sent to the portable device. Alternatively, a user may perform clicking and scrolling with respect to the image on the device to cause the actual execution in the virtual browser. The user may access a virtual desktop through the palm top device to create and modify documents.

Claims

1. A host to serve a remote device, the host comprising:

means for generating, at the host, a first image of a virtual desktop to indicate a state of the virtual desktop, the virtual desktop representing a graphical desktop environment for controlling the host;

means for sending the first image in a compressed image format to the remote device;

means for receiving a first message from the remote device, the first message indicating user input received with respect to the first image;

means for applying the user input to the virtual desktop at a location corresponding to a location at which the user input is received with respect to the first image at the remote device;

means for generating, at the host, a second image of the virtual desktop, the second image indicating a state of the virtual desktop after the user input is applied to the virtual desktop; and

means for sending the second image of the virtual desktop to the remote device.

2. A host as in claim 1, wherein the user input comprises a click on a point on the first image;

and, to generate the second image, the host applies a click to the virtual desktop at a point that corresponds to the point on the first image.

3. A host as in claim 2, further comprising:

means for sending, to the remote device, a second message from the host, the second message instructing the remote device to prompt for text input;

wherein the click applied to the virtual desktop allows text input at a location on the virtual desktop.

4. A host as in claim 1, wherein the user input comprises a double-click on a point on the first image;

and, to generate the second image, the host applies a double-click to the virtual desktop at a point that corresponds to the point on the first image.

5. A host as in claim 1, wherein the user input comprises a drag-and-drop on the first image;

and, the host applies a drag-and-drop to the virtual desktop at locations that correspond to locations where the drag-and-drop on the first image is received at the remote device.

6. A host as in claim 1, wherein the virtual desktop comprises a virtual web browser;

and, the virtual web browser renders web pages requested by the remote device at the host into images.

7. A host as in claim 1 further comprising:

means for dividing the first image into a plurality of sections;

wherein the plurality of sections are sent to the remote device in a sequence according to a display priority in the compressed image format.

8. A host as in claim 1, wherein the first image is sent from the host to the remote device through a wireless telecommunication link.

9. A host as in claim 1, wherein a size of the first image is different from a size of a display of the remote device.

10. A host as in claim 9, wherein the first image is larger than the display of the remote device.

11. A method to serve a remote device, the method comprising:

generating, at a host, a first image of a virtual desktop to indicate a state of the virtual desktop, the virtual desktop representing a graphical desktop environment for controlling the host;

sending the first image in a compressed image format to the remote device;

receiving a first message from the remote device, the first message indicating user input received with respect to the first image;

applying the user input to the virtual desktop at a location corresponding to a location at which the user input is received with respect to the first image at the remote device;

generating, at the host, a second image of the virtual desktop, the second image indicating a state of the virtual desktop after the user input is applied to the virtual desktop; and

sending the second image of the virtual desktop to the remote device.

12. A method as in claim 11, wherein the user input comprises a click on a point on the first image;

and, to generate the second image, the host applies a click to the virtual desktop at a point that corresponds to the point on the first image.

13. A method as in claim 12, further comprising:

sending, to the remote device, a second message from the host, the second message instructing the remote device to prompt for text input;

wherein the click applied to the virtual desktop allows text input at a location on the virtual desktop.

14. A method as in claim 11, wherein the user input comprises a double-click on a point on the first image;

and, to generate the second image, the host applies a double-click to the virtual desktop at a point that corresponds to the point on the first image.

15. A method as in claim 11, wherein the user input comprises a drag-and-drop on the first image;

and, the host applies a drag-and-drop to the virtual desktop at locations that correspond to locations where the drag-and-drop on the first image is received at the remote device.

16. A method as in claim 11, wherein the virtual desktop comprises a virtual web browser;

and, the virtual web browser renders web pages requested by the remote device at the host into images.

17. A method as in claim 11 further comprising:

dividing the first image into a plurality of sections;

wherein the plurality of sections are sent to the remote device in a sequence according to a display priority in the compressed image format.

18. A method as in claim 11, wherein the first image is sent from the host to the remote device through a wireless telecommunication link.

19. A method as in claim 11, wherein a size of the first image is different from a size of a display area of the remote device.

20. A method as in claim 19, wherein the first image is larger than the display area of the remote device.

21. A machine readable medium containing executable computer program instructions which when executed by a data processing system cause said system to perform a method to serve a remote device, the method comprising:

generating, at a host, a first image of a virtual desktop to indicate a state of the virtual desktop, the virtual desktop representing a graphical desktop environment for controlling the host;

sending the first image in a compressed image format to the remote device;

receiving a first message from the remote device, the first message indicating user input received with respect to the first image;

applying the user input to the virtual desktop at a location corresponding to a location at which the user input is received with respect to the first image at the remote device;

generating, at the host, a second image of the virtual desktop, the second image indicating a state of the virtual desktop after the user input is applied to the virtual desktop; and

sending the second image of the virtual desktop to the remote device.

22. A medium as in claim 21, wherein the user input comprises a click on a point on the first image;
