Recently, the film industry is showing interest in emerging technologies, such as Virtual Reality (VR). A milestone in this direction was the special award presented by the Academy of Motion Picture Arts and Sciences Board in 2017 to Carne y Arena directed by Alejandro G. Iñárritu. Carney Arena is a VR installation which was said to be opening “new doors of cinematic perception”. This follows on from the work of an increasing number of festivals (like Berlinale and the Venice Film Festival), filmmakers and researchers who are investigating the potential of using new interactive technologies in cinema.
Among the most recent innovations are new wireless Brain-Computer Interfaces, which are now available in the market as low-cost headsets. They are already used in computer games and the arts, but more recently they have been applied in interactive filmmaking as well. For example, Hollywood studios, like Universal and 20th Century Fox have released interactive versions of their films, where the spectator can control key moments of the plot with the use of a BCI headset.
