An information retrieval device displays portions of a dynamically modifiable document requested by a user. The information retrieval device has a controller connected to a display screen, input selector switches, such as buttons, and memory, such as non-volatile flash memory. One or more documents, such as a newspaper or magazine, is stored in the memory. A receiver, such as a pager, modem, or FM radio receiver, is connected to and dynamically updates the memory. When the device is turned on, a first portion of a document is displayed on a display screen. When the user wants to see a different portion of the document, or a different document altogether, she presses one of the buttons. Upon detection that a button was enabled, an action is performed that changes the display on the display screen. The action performed can vary in complexity: it may simply cause the next page of the document to be displayed, or may execute a nested hypertext link to cause related information contained in the same or a different document to update only a portion of the display screen. The document is stored in the memory in a manner that allows the display screen to be refreshed directly from the memory. When an updated portion of a document is received by the receiver, that portion of memorv is updated.

Selective user coupling for shared object oriented computer system

An object based computer system has viewers which may be directed around the object world of the system between semantic objects. The system includes a sequence object that has a path list specifying a path around a sequence of semantic objects of system. Each viewer can be linked to the sequence object to access the path list held by the latter, thereby enabling the viewer to follow the corresponding sequence of semantic objects, viewing each in turn.

Sequentially navigated object oriented computer system

An information retrieval device displays portions of a document requested by a user. The information retrieval device has a controller connected to a display screen, input selector switches, such as buttons, and non-volatile memory, such as a removable ROM. One or more documents, such as a book or magazine, is stored in the non-volatile memory. When the device is turned on, a first portion of a document is displayed on a display screen. When the user wants to see a different portion of the document, or a different document altogether, she presses one of the buttons. Upon detection that a button was enabled, an action is performed that changes the display on the display screen. The action performs can vary in complexity: it may simply cause the next page of the document to be displayed, or may execute a nested hypertext link to cause related information contained in the same or a different document to update only a portion of the display screen. The document is stored on the non-volatile memory in a manner that allows the display screen to be refreshed directly from the non-volatile memory.
