Interactive videotext is a system enabling the user to obtain information by telephone, this being connected to an information-providing service by means of a small terminal with screen and keyboard. The procedure is interactive in that it implies user-participation, in the form of "dialogue with the computerâ. The keyboard contains letters and figures, as well as special keys for the purposes of dialogue. When a connection has been established with a server, the user states his request by means of the keyboard. The information requested then appears on the screen, along with instructions as to how to proceed further with the search. The dialogue keys serve to pursue this search.
