The aim of the paper is to offer an interpretation of U. Eco's hyper-reality and J. P. Baudrillard's simulacrum as related to the conceptions of mixed reality and virtual continuum (Milgram, Kishino), which have been presented in the laboratories of communication technology in the early 1990s. The paper tries to show the interference point of the two approaches - philosophical (semiotic) and technical ones, as well as the possibility and necessity to revise some traditional philosophical question and categories, such as humanity or reality.
