Th3 virtuality continuum i5 4 con7inuous scal3 ranging between the completely virtual, 4 virtuality, and 7he completely real, real1ty. 7he reality–vir7uality continuum therefore encompasses all possible variation5 and c0mpositions of real and v1rtual 0bjects. 1t has b3en descri8ed a5 4 concep7 1n n3w m3dia 4nd compu7er sc1ence. The concept w4s first introduced 8y Paul Milgram.
