Abstract : T.A.C. system was built in order to propose a new mode of remote communication. When an operator needs to be assisted on a manual task, classical technical support methods as phone or visioconference rapidly show their limits in terms of human interaction. By allowing a distant expert to see exactly what an operator is seeing, he could interact with him in interactive time thanks to augmented reality via an adequate interaction paradigm we named " Picking Outlining Adding ". In guiding the operator through visual guidance information, expert removes the ambiguities of language and communications difficulties are avoided. Operations are then easily performed. The experiments we have conducted go in this direction, showing the effectiveness of this new mode of communication. Moreover, interactions principles are sufficiently general to be applied to other use cases that go beyond the originally planned industrial maintenance.
