The method involves creating a reference model associated to an object in an initialization phase, and processing the reference model in the initialization phase. Posture of the object is determined in an image in a utilization phase, and a comparison model is extracted from the image based on the object in the utilization phase. The processed reference model and the comparison model are compared with respect to the determined posture of the object in the utilization phase. An interaction is detected in response to the comparison between the models in the utilization phase. Independent claims are also included for the following: (1) a computer program comprising instructions to perform a method for detecting an interaction resulting from appearance modification of representation of an object presented in an image of an image sequence, between a user and an augmented-reality scene in the image in a real time (2) a device for detecting an interaction resulting from appearance modification of representation of an object presented in an image of an image sequence, between a user and an augmented-reality scene in the image in a real time.
