One of the most interesting research lines about avatars is the design and the implementation of a synthetic behaviour able to drive avatar's actions according to an adaptive interaction paradigm. This aspect, indeed, is of fundamental importance to many advanced applications involving avatars and humans. This study presents a novel framework exploiting augmented reality to visualize a synthetic 3D virtual guide inside an exhibit or a public gallery, to assist visitors wearing a Head Mounted Display during their visit and providing them with both visual and informative enhancements not available in a standard tour. The Human-avatar interaction is approached through a model based on timed automata to address the conversational issues and to improve the quality of interaction by means of an effective synchronization. A usability study conducted on an application of this research to the ''avatar assisted tour'' of a roman villa, confirms the efficacy of the approach.
