Description

PORTABLE HIGH SPEED INTERNET ACCESS DEVICE AND WEB SITE

Prior Art

The background of the present invention includes US Patent # 5925103, Internet Access Device, which describes an improved Internet access system, vastly different from the present invention. Other prior art would include palm top computers and hand-held computers that have limited processing power due to design restrictions. Thus, these computers are much slower for accessing the Internet and World Wide Web.

The present invention enhances the server's processing speed, data transfer and retrieval to and from the portable devices, with the aid of specialized embedded software in the server. The result is a cost effective Internet access solution.

Summary

It is an object of the present invention to disclose a portable device that can access the Internet and World Wide Web, at extremely low costs. It is another object of the present invention to provide fast access to the Internet such that refreshing pages is quick and efficient.

The principal embodiment of the present invention discloses a portable device that comprises a modem that connects to a cellular telephone. Thus, the device has a wireless connection to the Internet. A host computer, which may also be a Web server connects directly to the Internet. The host computer comprises multiple software programs, for example a Browser Translator, which translates HTML images into black and white bit map or raster images. The compressed bit map or raster images are sent to the portable device, and the device decompresses the images. Thus, the user views a bit map image of a Web page. A Web site is available to the user to modify the parameters ofHhe virtual browser. By logging onto the Web site, the user may select which changes are to be implemented. The changes are sent to the server, and the virtual Web browser is modified.

The portable device comprises methods for pointing and clicking on text and images representing links to other Web pages. Clicking events are sent to the host computer that performs the commands via a virtual browser. The host computer then sends the required information to the portable device as a compressed image. The portable device decompresses the image and the user views a new page.

DETAILED DESCRIPTION OF THE PRESENT INVENTION

The principal embodiment of the present invention aims to provide a device that allows a user to access the Internet or the World Wide Web (WWW), which device is similar to a palm top computer. It is a further aim of the present invention, to reduce the cost of the device. It is a further aim of the present invention, is to increase the speed of refreshing the screen when the user clicks on a link and commands another page to be displayed.

Currently, existing palm top devices such as the Palm Pilot VII and Windows CE type devices contain an operating system, and within the operating system a mini- browser to interpret information received from the WWW or Internet and then display this information on the screen. This requires a powerful microprocessor.

The principal embodiment of the present invention is disclosed in Figure 1. A host computer 1 is depicted that is connected to the Internet and may also be a Web server. Running in the host computer, is a Web server program 2. When a remote user 3 requests to view a Web page (or electronic message etc.) the Web server software receives HTML, JAVA, etc. information and transmits this information to another software, the Browser Translator 4. This software translates the information, (i.e. the entire image comprising graphics and text) received in the form of HTML, Java, etc. (information may be gathered from different sources) and translates it to a black and white bit map or raster image. In another embodiment, the software translates the information into a raster or color image. The image 5, as shown in Figure 2, contains the information that would normally be displayed on a single Web page. The translation program therefore, also acts as a virtual browser 6. As can be seen in Figure 2, the image 5 to be displayed in a browser window 6 is usually larger than the displayable area of the browser window 6. The image 5 is further divided into sections 7, 8, 9, and 10, as shown in Figure 3. The image is divided after the bitmap or raster is created. The reason for the division (as will be explained later) is for the purpose of display priority on the user's display. The image 5 is then sent to another program 11 running on the host computer 1 (Fig. 1), which compresses the image using a loss-less compression method. The compression method may be group 3 or group 4, or another method.

The programs 4 and 11 can have multiple instances running simultaneously on the host server for the purpose of connecting to multiple users. The compressed image, after being processed by program 11, is sent to the user, using a protocol in which information may be broken down into packets.

The information is received by a palm top device 12 that has the ability to display a monochrome image, in its display window 13. The information is decompressed and displayed in the order of priority such that part of image 7, which substantially or completely covers the displayable area 13 (Fig. 2), of the palm device is decompressed and displayed first and then sequentially the portions 8, 9, 10 of the image are decompressed and stored in an internal memory of the palm top device to be displayed later when the user scrolls up, down, or sideways to these parts of the image.

A CPU resident in the palm top device therefore has the ability to decompress a bit map or raster image that may be larger than the size of the display and allow the user to traverse this bit map or raster image. The primary method of traversing the image is through conventional scroll bars positioned at the sides of the image.

The resident CPU on the palm top device has no ability to determine which parts part or parts of the image, that is being displayed, represent links to other Web pages etc. Thus, the translator program 4 (Fig. 1) translates the image in the virtual browser 6 such that the words that represent links on the page 5 (Fig. 2) are translated to be slightly bolder. The user may therefore consider text that is bold to be links. The palm top device provides the user with a pointing device. This pointing device may be a touch screen or tracking ball, etc. The palm top device also allows the user to click on specified areas. As soon as the user clicks on part of an image, the shape of the pointer changes from an arrow to an hourglass. A message is sent to the host computer, transmitting the location of the clicked down event. A program 14 interprets the message and provides a virtual click down in the virtual browser created in the translator program 4. If the user has pressed in an area of the image that does not represent a link or text box, a message is dispatched to the palm top device which immediately changes the hourglass shape of the pointer back to an arrow (in the case of a touch screen, from an hour glass to nothing). Further to this, if the user has clicked on a part of the image which represents a link, a new Web page is extracted from the Internet or WWW, translated by translator program 4 (Fig 1) into a bit map or raster, and compressed by compression program 11 and dispatched to the palm top device where a new page is displayed. Furthermore, the image 5 is continuously being updated and translated and sent to the palm top device where it is continuously being refreshed. This occurs once every few seconds.

When the user clicks in a text box or in a box in the display area into which letters or numbers must be input, the cursor first changes into an hourglass, and a message is sent to the host server. The host server recognizes that the click down event has occurred in the text box, and sends a message back to the palm top device to inform the palm top device to pop-up a keyboard on part of the screen. The user then types, using the pointer, the letters or words to be entered into the text box and presses "enter" or "go". The keyboard then disappears and the cursor changes back to an hourglass shape (in another embodiment, the keyboard could be replaced with a real keyboard or with an area that recognizes users' handwriting). The information typed into the text box is transmitted in a message to the host computer. The host computer enters the information into a text box in the virtual browser.

The user sees, after a short pause, as the image is refreshed on the palm top device, that the words, or letters or numbers have been entered into the text box. Further to this, the host computer may also break up the image such t at the portion that has been changed, i.e. the text box area, is sent first. A Web site is disclosed where the user is able to adjust the parameters of the virtual browser and consequently, change how the browser is viewed on the device. Parameters that may be changed include font, font size and the size of the window, of the virtual browser.

The reason why the user may want to change the size of the virtual browser window is because the browser or Web sites may display information differently for different sizes of the virtual browser window. Usually, the user wants the virtual browser window to be the same size as the device so that the browser or a Web site may display image optimally for that display area.

A Web site is disclosed that would allow the user to enter information about the display characteristics of the virtual browser. This Web site then sends a message to a software in the host computer that changes the display characteristics of the virtual browser. Another to accomplish these tasks would be during the set-up time or another time, a program resident on the device may allow the user to enter information that can be transferred to a program on the host computer to modify the may the information is viewed by the user.

In another embodiment of the present invention, images are only refreshed when an event occurs such as a mouse down event on a link or in a text box.

In a further embodiment only those portions of the image that changes may be transmitted from the host computer to the palm top device. Other images in the virtual browser that are continuously changing, such as banner advertisements, may be the only other images sent to the palm top computer as they change.

In the principal embodiment, the palm top device also contains a modem, which can be linked to the user's mobile telephone 15 and information that is communicated between the palm top device and the host computer is sent and received wirelessly through the mobile telephone. Furthermore, the palm top device only contains enough rftemory to store^he current displayable page. When the user presses a back or forward button, a message is sent to the host server, and the host server sends the reference page. The back and forward buttons etc. may be hard wired into the palm top device, or may be part of the display area.

Further to this, part of the image representing buttons (and other things) on the virtual browser may be sent as part of the compressed image and buttons such as forward and back may be treated the same way as links are handled as previously , described.

In another embodiment, the palm top device comprises a modem that permits the device to connect to a cellular telephone 15 in digital format.

In another embodiment, the connection to the cellular telephone 15 is made through an analog modem connected to an ear jack of the cellular telephone.

In yet another embodiment of the present invention, the modem is replaced by an analog modem that has the capability to be connected to a landline providing a standard 56kbps-type connection.

Further embodiments may provide connections through ISDN, cable modems etc.

In a further embodiment, the palm top device may contain a large screen to be used in a fashion similar to a home Internet appliance.

In a further embodiment, the image transferred between the host computer and the remote device (previously the palm top device) may be a color image and the compression method used may be of a Jpeg or other compression methods used for color images. A gray scale image may also be used to reduce bandwidth or display costs.

In a further embodiment, the device includes no screen, but only outputs to be hooked to a television screen or external monitor for display. The remote device in the principal embodiment only has the ability to decompress the image it receives; display the image it receives; allow the user to scroll through the image; provide the user with a pointing device to point and click on the image; send messages providing location of click down event; provide the user with a method to input letters and numbers; send a message containing these letters and numbers.

The principal embodiment contains no other structured or intelligent information about the image.
