1. For use with a host computer having a plurality of user interface objects corresponding to a plurality of user interfaces and an intelligent terminal capable of interacting with objects as well as creating and storing objects, said host computer and said intelligent terminal being interconnected over a telecommunications network in an on-line mode for data transmission therebetween and in an off-line mode wherein no data is transmitted therebetween, a method of processing and transmitting data corresponding to one of the plurality of user interface objects between the host computer and the intelligent computer, the method comprising the steps of:

  • determining whether the one of the plurality of user interface objects is stored in the intelligent computer;

    if the one of the plurality of user interface objects is not stored in the intelligent computer, generating interface data representing the one of the plurality of user interface objects, the interface data providing full user interface utilities;

    transmitting said interface data over the telecommunications network in the on-line mode to the intelligent terminal;

    storing said interface data in the intelligent terminal;

    modifying the interface data in real time with user manipulated commands and actions by utilizing the intelligent Terminal in the off-line mode to obtain transitory interface data and modified interface data, the transitory interface data representing user manipulations not requiring intervention from said host computer, and the modified interface data representing user manipulations resulting in an alteration of the user interface and requiring intervention from said host computer;

    filtering said modified interface data from said transitory interface data in real time through the use of gating commands; and

    transmitting only the modified interface data upon a first occurrence of the modified interface data from the intelligent terminal to the host computer over the telecommunications network.
