This paper argues that current research on telepresence is dicotomized between works aiming at establishing consistent shared spaces and those supporting a sense of shared presence. The paper concludes that the integration of these two spaces is important: the smoothness of transitions. There are different cases and we should adapt technology to support this variety.
