Abstract

A method for the display of standardized Internet pages (for example, in HTML or XML standard), generated for display on large-size screens, on a small display on hand-held devices (mini-computer, PDA or mobile radio device) is disclosed, in which the hand-held device can be provided with a mobile radio connection to the internet. A virtual large image memory is maintained in the device. Within the large virtual image the device display can be freely displaced as a readable image section. A zoom function permits an overview and coarse positioning of the detailed representation. The detailed representation can be continuously moved around within the virtual image in the form of a screen section by means of a pointer device (mouse pointer) by moving the mouse pointer to the display edge (and beyond). Switching can be performed at any time between the display modes.

Claims

1. A handheld device for displaying a standardized full image Internet page created for display on large-area displays using HTML or XML protocol, said handheld device comprising:

a display, said display being relatively small when compared to said large-area displays;

a first screen memory storing the full image Internet page as a large-format full image virtual screen;

a second screen memory used as a display buffer memory, the display buffer memory storing portions of contents of the large-format full image virtual screen being displayed on the display of the handheld device;

a positioning key tactile element arranged on a front of the handheld device for thumb control and for positioning a pointer device on the display of the handheld device to select an area which is to be enlarged or reduced, where said positioning key tactile element allows the pointer device to be freely positioned on the display of the handheld device such that by moving the pointer device to a display edge on the display of the handheld device, the portion of contents of the large-format full image virtual screen being displayed is continuously shifted and displayed; and

a zoom key tactile element arranged on a back of the handheld device for middle-finger control for enlarging or reducing the selected area either to a clearly readable enlarged format, or to a point where a desired level of enlargement has been achieved, wherein the two tactile elements are arranged ergonomically on the handheld device such that it is possible to control both keys with one hand without changing the respective grip position,

and wherein when displaying portions of contents of the large-format full image on the display, content for the display buffer memory is selectively obtained by performing a copy operation for copying the portions of the contents of the large-format full image virtual screen from the first memory to the display buffer memory or by use of mathematical or combinational logic functions including zoom functions;

or copying a current display area from the virtual screen to the display buffer memory is dispensed with and the display buffer'"'"'s memory positions are used within the virtual screen as a storage location vector for the display electronics.

2. A handheld device as recited in claim 1, wherein the positioning to select an area which is to be enlarged is performed using a stylus or finger on a touch-sensitive screen on the handheld device, using a tactile multicoordinate function.

3. A handheld device as recited in claim 1, wherein a user is capable of moving back and forth between the full image virtual screen and the image portion of the virtual larger image without losing image information through prior image reduction.
