Substitutional Reality HMD System Makes Reality and Fiction Indistinguishable

“The Riken Brain Science Institute is developing a substitutional reality (SR) system that makes reality and fiction indistinguishable.
The subject wears a head-mounted display (HMD), inside of which he views footage projected inside the HMD. The footage inside the HDM is of reality in real time. By switching the projected footage to something previously recorded in the location where the subject is located, the system can create the illusion that past footage is the reality occurring before his eyes. “
