Some commonly used terminology and technology when talking about virtual reality:
Having an overlay of virtual elements over top a real world view. Not necessarily tracked to real world spacing (ie: the objects may appear in the same place no matter where you turn your head).
Google’s mobile platform for virtual reality. Compatible with most new smart phones. Typically sit down or look around experiences.
Google’s next level up from Google Cardboard in their development in virtual reality. The Daydream is a headset and is only compatible with certain mobile phones.
HMD (Head Mounted Display)

A higher end virtual reality headset by HTC that uses lighthouse technology for room scale tracking. Requires a virtual reality ready PC, usually alluding to a higher graphics card requirement.
The ability to fully believe that a person is in the virtual experience – usually accomplished with sound isolation, proper tracking and a well-developed application.
Currently one of the hurdles in virtual reality development – being able to move in a virtual space without making the user experience motion sickness, or making the movement believable.
Microsoft’s mixed reality device that uses a headband device with a display that creates virtual objects and displays in a user’s real world environment. Typically the elements are tracked to real world elements.
Similar to augmented reality where there are virtual elements in a real world view, but the virtual elements are more interactive or mapped with real world spacing and physical obstacles.
