Juriev D.V. On the description of a class of physical interactive information systems (53K, AmSTeX) ABSTRACT. The paper is devoted to problems of mathematical physics of the kinematical description of a certain class of physical interactive information systems, which admit an extraction of the interacting active and passive agents. Applications of such systems as well as of artificial or integrated (semi-artificial) interactive information systems to various aspects (presumably, interface and driver ones) of the "information high-way" are discussed.
