a design paradigm that allows users to move freely within a room-sized environment while partaking in a virtual reality (VR) experience

Through the use of kinetic locomotion mechanics (in the Perambulation category), the experiencer’s physical movements are mirrored within the virtual world and helps to contribute to a greater sense of immersion, with the body being directly engaged – a key contributor to creating a state of embodied presence.

The term room-scale is often used to differentiate between other types of virtual reality experiences e.g. a self-contained environment of a VR room or seated or standing VR, in which the user remains stationary.
