After revision:  The reasons for the question being nontrivialare discussed , and a novel method is proposed . To some extent, the method is inspired by Turing`s test for AI, in that it involves a human challenger and the real and artificial entities, yet it is very different: our test is conditional, requiring from the artificial no more than is required from the original, and it employs a novel method of immersion that takes advantage of the availability of near-perfect reproduction methods for sight and sound.
