After nearly a century's development, virtual reality has won public attention and discussion in the early 1990s. Although this technology hasn't fully matured yet, its central idea has influenced the designs of many digital applications and has become an important feature of contemporary culture. From the early 1990s till today, there have been a series of Sci-fi films and televisions which explored the theme regarding virtual reality. A systematic examination of them would help us understand what kinds of popular hopes and fears about virtual reality have been disclosed. This study will draw upon the works of McLuhan, Rheingold, Heim, and Foucault to ponder on the relationships between simulation and reality, human and technology, and to reconsider the future of virtual reality.
