Abstract

The invention discloses a portable device that allows the user to access the Internet and World Wide Web. The portable device includes a modem that connects to a cellular telephone, thus the portable device connects wirelessly to the Internet. A host computer that may also be a Web server, is connected to the Internet and comprises various software programs to translate and compress into bit map or raster images the information received from the Internet. The compressed image is sent the portable device and the device is capable of decompressing the compressed image. Thus, the user views a bit map image of a Web page. The portable device further comprises methods of pointing and clicking on text and images which represent links to other pages. All commands that the user enters into the portable device are sent to the host computer, which performs the commands via a virtual browser, and sends the information back to the portable device.

Claims

1. A method to display a document, the method comprising:

sending a request for a remote document from a device to a remote server, the remote document having first displayable information in a non-image

receiving at the device a first compressed section of an image from the remote server, the image being rendered from the entire remote document in response to the request, a portion of the image being rendered from the first displayable information;

decompressing the first compressed section to generate a first decompressed section of the image;

displaying at least a portion of the first decompressed section at a location of a display area of the device; and

automatically receiving at the device a second compressed section of the image from the remote server, the second compressed section corresponding to a second section of the image, the second section of the image being outside the display area of the device when the portion of the first decompressed section is displayed at the location of the display area of the device.

2. A method as in claim 1 wherein the first displayable information comprises at least one of:

a) text;

b) text box;

c) Java; and

d) HTML.

3. A method as in claim 1 wherein the device decompresses compressed sections of the images according to a display priority.

4. A method as in claim 1 further comprising:

receiving location information from the remote server, the location information specifying in the image at least one location at which a user input can be accepted for an operation at the remote server with respect to the remote document; and

communicating the location information to a user of the device.

5. A method as in claim 4 wherein the at least one location comprises a location of one of:

a) a link to a document; and

b) a text box.

6. A method as in claim 8 wherein said communicating comprises:

determining whether or not a cursor is displayed on the device at a location on the image at which a user input can be accepted for an operation at the remote server with respect to the remote document; and

displaying a feedback in response to a determination that the cursor is displayed on the device at a location on the image at which a user input can be accepted for an operation at the remote server with respect to the remote document.

7. A method as in claim 6 wherein said displaying the feedback comprises:

changing a shape of the cursor.

8. A method as in claim 1 further comprising:

scrolling at exclusive control of the device to display the image.

9. A method as in claim 1 wherein the image is black and white, reduced from the remote document.

10. 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 display a document, the method comprising:

sending a request for a remote document from a device to a remote server, the remote document having first displayable information in a non-image format;

receiving at the device a first compressed section of an image from the remote server, the image being rendered from the entire remote document in response to the request, a portion of the image being rendered from the first displayable information;

decompressing the first compressed section to generate a first decompressed section of the image;

displaying at least a portion of the first decompressed section at a location of a display area of the device; and

automatically receiving at the device a second compressed section of the image from the remote server, the second compressed section corresponding to a second section of the image, the second section of the image being outside the display area of the device when the portion of the first decompressed section is displayed at the location of the display area of the device.

11. A medium as in claim 10 wherein the first displayable information comprises at least one of:

a) text;

b) text box;

c) Java; and

d) HTML.

12. A medium as in claim 10 wherein the device decompresses compressed sections of the images according to a display priority.

13. A medium as in claim 10 wherein the method further comprises:

receiving location information from the remote server, the location information specifying in the image at least one location at which a user input can be accepted for an operation at the remote server with respect to the remote document; and

communicating the location information to a user of the device.

14. A medium as in claim 13 wherein the at least one location comprises a location of one of:

a) a link to a document; and

b) a text box.

15. A medium as in claim 13 wherein said communicating comprises:

determining whether or not a cursor is displayed on the device at a location on the image at which a user input can be accepted for an operation at the remote server with respect to the remote document; and

displaying a feedback in response to a determination that the cursor is displayed on the device at a location on the image at which a user input can be

accepted for an operation at the remote server with respect to the remote document.

16. A medium as in claim 15 wherein said displaying the feedback comprises:

changing a shape of the cursor.

17. A medium as in claim 10 wherein the method further comprises:

scrolling at exclusive control of the device to display the image.

18. A medium as in claim 10 wherein the image is black and white, reduced from the remote document.

19. A device to display a document, the device comprising:

means for sending a request for a remote document from a device to a remote server, the remote document having first displayable information in a non-image format;

means for receiving at the device a first compressed section of an image from the remote server, the image being rendered from the entire remote document in response to the request, a portion of the image being rendered from the first displayable information;

means for decompressing the first compressed section to generate a first decompressed section of the image;

means for displaying at least a portion of the first decompressed section at a location of a display area of the device; and

means for automatically receiving at the device a second compressed section of the image from the remote server, the second compressed section corresponding to a second section of the image, the second section of the image being outside the display area of the device when the portion of the first decompressed section is displayed at the location of the display area of the device.

20. A device as in claim 19 wherein the first displayable information comprises at least one of:

a) text;

b) text box;

c) Java; and

d) HTML.

21. A device as in claim 19 wherein the device decompresses compressed sections of the images according to a display priority.

22. A device as in claim 19 further comprising:

means for receiving location information from the remote server, the location information specifying in the image at least one location at which a user input can be accepted for an operation at the remote server with respect to the remote document; and

means for communicating the location information to a user of the device.

23. A device as in claim 22 wherein the at least one location comprises a location of one of:

a) a link to a document; and

b) a text box.

24. A device as in claim 22 wherein said means for communicating comprises:

means for determining whether or not a cursor is displayed on the device at a location on the image at which a user input can be accepted for an operation at the remote server with respect to the remote document; and

means for displaying a feedback in response to a determination that the cursor is displayed on the device at a location on the image at which a user input can be accepted for an operation at the remote server with respect to the remote document.
