Abstract: A method is provided for tracking at least one use of at least one piece of multimedia content on a terminal connected to a communication network. The piece of content is transmitted to the terminal in the form of at least one description file generated according to a predetermined description format. The method includes using the piece of content by a user of the terminal, including activation of at least one interaction element; implementing at least one instruction followed by the use associated with the activated interaction element; executing the use tracking instruction controlling storage of at least one piece of information concerning the activation of the interaction element, or use tracking information; and transmitting by the terminal the piece of use tracking information to a tracking terminal in charge of processing the use tracking information.

Abstract: The invention relates to a method of decoding at least one image of a physical object as an action executable by a mobile terminal. According to the invention, such a method comprises the following steps: establishment of a bidirectional communication between said terminal and a translation server, said establishment step comprising the following substeps: capture of said image or images of said physical object by said terminal; transmission, from said terminal to said translation server, of said image or images captured; reception, by said terminal, of at least one item of information representative of an action executable by said terminal, termed the action information, and corresponding to a decoding, by said translation server, of said image or images transmitted.
