Room-scale is a design paradigm for virtual reality experiences which allows users to freely walk around a play area, with their real-life motion reflected in the VR environment. Using 360 degree tracking equipment such as infrared sensors, the VR system monitors the user's movement in all directions, and translates this into the virtual world in real-time. This allows the player to perform tasks, such as walking across a room and picking up a key from a table, using natural movements. In contrast, a stationary VR experience might have the player navigate across the room using a joystick or other input device.
