A reader for displaying an electronic document stored in a predetermined format and allowing articles of the document to be read in the direction of their content information flow. The reader includes a selector to select an article of the document to be read. A displayer displays a first portion of the article in a manner which promotes comfortable viewing, and a navigator permits the display of the next and remaining sequential portions of the article in content flow (or reverse content flow) order. Preferably, the displayer pans and zooms, as necessary, to position the article portion in an article viewing window. A method for viewing electronic documents on a digital computer includes the steps of storing in the memory of the digital computer an electronic document, selecting an article to be displayed on an output device of the digital computer in an article view, displaying at least a portion of the article in the article viewing mode on the output device, and using an input device of the digital computer to cause a display of additional portions of the article to be displayed on the output device in the article viewing mode. These additional portions of the article are determined, at least in part, by predefined article sections and section links of the document so that the thread of the article can be followed in forward and reverse directions.
A base station manager for use in a cellular telephone system includes fonts having different sizes. The base station manager detects a change in a size of a widget, measures the size of the size-changed widget, measures the size of the fonts associated with the size-changed widget, compares the size of the fonts with the size of the size-changed widget and reads pre-stored fonts corresponding to the size-changed widget, and changes the font size of the size-changed widget into the size of the pre-stored fonts. In this manner, the base station manager of the invention may readily change the font size according to the variation of the widget size, without incurring additional expenses.
Aspects of the present invention provide a system and method for scrolling or dragging information on a display. A panning tool is provided that may scroll information, such as a web page, on a display in tandem with movement of a cursor. If interactive elements are present on the page or document, an interactive element may be activated as desired. Scrolling may be accomplished with the panning tool either on non-interactive elements or interactive elements that are not required to be activated. Furthermore, inertia of movement of the information on a display is optimized and autoscrolling is provided in which a page or document may be scrolled without dragging.
In a system which permits different components of a document to be linked, a unique token is associated with a change to data in the source of a link. The token is passed with a command to update linked data. Each destination object keeps track of the token associated with the last change made to its linked data. When a new command to update linked data arrives at the destination object, the token for that update is compared with the token for the previous update. If the tokens are the same, an alert is presented to the user to indicate that either the change has been propagated around a cycle, or more than one update path exists between the source object and the destination object. In response, the user can elect to prevent the change from being carried out in the destination object, in which case the cycle is broken. Alternatively, the user can elect to let the update continue, for example in those situations in which multiple update paths are desirable.
An edit command delegation (ECD) utility that provides a user with the ability to edit an electronic file in a creator application program while the electronic file is open in a separate viewing application program operable only for viewing the electronic file. In response to a user input to edit the electronic file, the ECD utility opens the electronic file and reads an application identification tag contained within the content of the electronic file. The application identification tag identifies a creator application program, which was used to create the electronic file and is operable for editing the content data of the electronic file. Once the ECD utility reads the application identification tag, the ECD launches the creator application program. The ECD utility then causes the creator application program to open the electronic file. Once the electronic file is open, the content data is displayed in a window controlled by the creator application program to allow the user to edit the content data.
The invention relates to a method and arrangement for reading hypertext pages especially on mobile phone display screens. A device is provided with a program which "understands" some basic rules of written language such as punctuation, conjunctives connecting parts of sentences, and the direction of reading. A low-resolution display (300) is divided into a navigation pane (320) and read pane (330). The selected hypertext page is decoded, and an overall view thereof, preprocessed in a predetermined manner, is brought into the navigation pane. A length of text cut off according to the said rules is brought at a time into the read pane from the area indicated by a cursor (310). The text is so short that it is easily readable as far as the size of the characters is concerned. The device has predefined key functions to move forward or backward in the text one step at a time or by skipping text passages if desired. The words displayed at a time on the display constitute a factual entity or at least belong to the same factual entity, whereby the reading of the text on the hypertext page is easy despite the limitations of the display. The invention may also be used for data searching in a relatively large mass of information.
