Computer networks simultaneously sharing images and data with individual scan and reset by a plurality of users - systems, methods & program products

摘要

A computer network including a server for receiving and sharing a presentation of foils with a plurality of user clients under the control of a presenter. Each user client has a terminal for displaying the foils; a browser for interacting with the server and a cache for storing the foils. Each foil is contained in a data structure, typically a HyperText Markup Language (HTML) page including a time line of past foils which enables a user through an interface to view each foil, scan over the time line to view any past foil and quickly reset the presentation to the current foil viewed on the network by the other user clients. Each user or viewer in scanning or browsing through the past foils does not interfere with other user clients viewing the presentation or to the presenter.
