Full-Dive Virtual Reality is a popular term used by futurists to describe a hypothetical future version of Virtual Reality that would be capable of emulating all human senses, and may be difficult for a user to differentiate from true reality. It differs from traditional Virtual Reality in that it is often depicted as stimulating the brain directly with technology such as electrode implants or magneticic fields to emulate senses, instead of using external hardware such as Virtual Reality Headsets, Omni Directional Treadmills, or Haptic Gloves. Most depictions of Full-Dive VR involve the user's body being immobile during use.

Locomotion Problem
A significant problem with emulating virtual environments with traditional methods (external hardware) is something called the Locomotion Problem, which refers to the difficulties related to movement through virtual environments in a convincing way. One common method of allowing the user to move through a virtual environment is through the use of a "joystick", where the user simply presses in the direction they wish to travel, without moving their actual legs. A common problem with joystick locomotion is that many users will experience motion sickness while their virtual body glides around, and their physical body stays at rest. . A popular solution for the motion sickness caused by joystick locomotion is an alternative form of locomotion called "teleportation", where the user simply points to the location they wish to travel and their virtual body is instantly moved to that location. Although both of these methods allow a user to move about in a virtual environment, neither involve the actual movement of the user's legs or body, and can be disappointing for users who desire more immersive experiences. To alleviate this, companies have designed external hardware such as Omni Directional Treadmills or wheeled "VR Boots" which translate a user's leg motion into movement instructions within the virtual environment, and allow a user to walk endlessly during a session. These external hardware solutions are often expensive and require a large floor space for setup, and are therefore impractical for the average user. All traditional locomotion methods that use external hardware are unable to cater to complex locomotive actions such as "climbing rocks", "rolling", etc, in a convincing manner. With a Full-Dive VR system, a user would not be constrained by any limit of external hardware. The user's body in the real world would be immobile, and they could attempt any complex body motion in the virtual environment since their brain signals would be sent directly to the VR system and would be ignored by their real body counterparts.
