MR is the predominantly virtual spaces where real world objects or people are dynamically integrated into virtual worlds to produce new environments and visualizations where physical and digital objects co-exist and interact in real time.
There are two ways Mixed Reality can be used. The first is more traditional, it involves a desktop set up in which learners explore a virtual environment using computer, keyboard, mouse, or some other input device, for example a wireless controller: this is properly defined as Virtual Reality.

The second is what today we use to identify as actual MR: it is the fully immersive experience that requires students to wear an HMD (head mounted display) and motion controller, through which they can interact with an environment produced by a mix of real and virtual worlds, where physical and digital objects co-exist.
