"To researchers and technicians working with robots on a daily basis, it is most often obvious what is part of the staging and not, and thus it may be easy to forget that illusions like these are not explicit and the that the general public may actually be deceived. Should the disclosure of the illusion be the responsibility of roboticists? Or should the assumption be that human beings, on the basis of their experiences as an audience in film, theatre, music or video gaming, assume the audience is able to enjoy the experience without needing to know everything in advance about how the illusion is created? Therefore, we believe that a discussion of whether or not researchers should be more transparent in what kinds of machines they are presenting is necessary. How can researchers present interactive robots in an engaging way, without misleading the audience?"
