Abstract

A method for the display of standardised 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 thus 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 method for displaying standardized Internet pages, which have been created for display on large-area screens (for example using HTML or XML protocol), on small displays on handheld terminals (handheld devices HD, such as mobile radios or PDAs), characterized in that the handheld device (HD) manages a relatively large screen display, going beyond the display resources of the handheld device (HD), both electronically (display memory) and in tactile form, within which screen display a respective clearly readable portion of the full image can be selected by the user by means of tactile or voice control and can be displayed on the unit'"'"'s small display as an image portion of a virtual larger image.

2. The method as claimed in claim 1, characterized in that the handheld device (HD) has two screen memories, with a smaller screen memory being used as a buffer store for the display (display buffer DB) and a larger screen memory being used to hold the large-format (virtual) full image (virtual screen VS), the content of the display buffer (DB) being ascertained by means of a copy function from the virtual screen (VS) or by means of mathematical or combinational logic functions (zoom function).

3. The method as claimed in claim 2, characterized in that when displaying portions without reducing the displayed content, copying the current display area from virtual screen (VS) to the display buffer (DB) is dispensed with if, by way of replacement, the display buffer'"'"'s memory positions are used within the virtual screen (VS) as a storage location vector for the display electronics.

4. The method as claimed in at least one of claims 1-3, characterized in that a pointer device (mouse pointer or the like) is positioned as a selection criterion for the center of an area which is to be enlarged on the reduced displayed content of the VS (the Internet page) using a stylus or finger on a touch-sensitive screen on the handheld device (HD display), using a tactile multicoordinate function or using voice input, after which there is subsequent enlargement to a readable enlarged format, or optionally the continuous enlargement by releasing the positioning function, by voice input or by additional pressing of keys.

5. The method as claimed in at least one of claims 1-4, characterized in that switching to and fro and repeated positioning and selection within the reduced displayed content can be combined as desired.

6. The method as claimed in at least one of claims 1-5, characterized in that optional, preferably continuous shifting of the portioned displayed content on the screen on the handheld device (HD display) within the virtual screen (VS) can be effected by virtue of the pointer device being moved to a page margin on the screen of the handheld device (HD display). Instead of further shifting beyond the margin, the portion window is shifted to the same degree within the virtual larger image.

7. The method as claimed in at least one of claims 1-6, characterized in that a preferred form of the display control is provided by means of two tactile elements, where a positioning key (3.5) allows the pointer device to be freely positioned on the screen of the handheld device (HD display) while a zoom key (3.4) is used to enlarge or reduce the selected areas, where the two control elements are preferably arranged ergonomically on the housing such that it is possible to control both keys without changing the respective grip position. This is possible, by way of example, as a result of the positioning key being arranged on the front for the purpose of thumb control and the zoom key being arranged on the back for middle-finger control.

8. The method as claimed in at least one of claims 1-7, characterized in that the tactile elements for the display control are engaged repeatedly, if required, for other functions of the unit, which are provided by means of software.
