IPC: G06F13/00
Filed: 1996-02-28
Abstract: Information "feeds" received from multiple information sources are aggregated, re-formatted and stored in a personalized real time information display system. When the display system receives a request from a user having a personal computer or other similar display device, the system is arranged to respond with information needed to display a screen saver that includes personalized, up to date information, such as traffic, weather and sports, that is of interest to that particular user. Each user has a personalized user profile indicating (a) the categories or types of information that the user desires to receive, such as sports information, weather, investment advisories, and son on, and (b) parameters that specify, for that user, the exact information desired to be received in each category.  If the user's personal computer display has remained inactive for a predetermined period of time, the screen saver is activated, causing the personal computer to access the service node, and after interchange of prestored user identification and password data, retrieve information, obtained by the system from a variety of sources, based on the user's individual profile. The retrieved information is displayed on the screen without interrupting the screen saver function, and the displayed personalized data is thereafter updated in the same manner, at user-specified time intervals.
