Mixed reality (MR) is a term used to describe the merging of a real-world environment and a computer-generated one. Physical and virtual objects may co-exist in mixed reality environments and interact in real time. Mixed reality that incorporates haptics has sometimes been referred to as Visuo-haptic mixed reality. In a physics context, the term "interreality system" refers to a virtual reality system coupled with its real-world counterpart. A 2007 paper describes an interreality system comprising a real physical pendulum coupled to a pendulum that only exists in virtual reality. This system has two stable states of motion: a "Dual Reality" state in which the motion of the two pendula are uncorrelated, and a "Mixed Reality" state in which the pendula exhibit stable phase-locked motion, which is highly correlated. The use of the terms "mixed reality" and "interreality" is clearly defined in the context of physics and may be slightly different in other fields, however, it is generally seen as, "bridging the physical and virtual world". Applications Mixed reality has been used in applications across fields including design, education, entertainment, military training, healthcare, product content management, and human-in-the-loop operation of robots. Education Simulation-based learning includes VR and AR based training and interactive, experiential learning. There are many potential use cases for Mixed Reality in both educational settings and professional training settings. Notably in education, AR has been used to simulate historical battles, providing an unparalleled immersive experience for students and potentially enhanced learning experiences. In addition, AR has shown effectiveness in university education for health science and medical students within disciplines that benefit from 3D representations of models, such as physiology and anatomy. Entertainment From television shows to game consoles, mixed reality has many applications in the field of entertainment. The 2004 British game show Bamzooki called upon child contestants to create virtual "Zooks" and watch them compete in a variety of challenges. The show used mixed reality to bring the Zooks to life. The television show ran for one season, ending in 2010. The 2003 game show FightBox also called upon contestants to create competitive characters and used mixed reality to allow them to interact. Unlike Bamzoomi's generally non-violent challenges, the goal of FightBox was for new contestants to create the strongest fighter to win the competition. In 2009, researchers presented to the International Symposium on Mixed and Augmented Reality (ISMAR) their social product called "BlogWall," which consisted of a
