a form of non-verbal communication through the body – typically the hands or head – that, when tracked by a motion sensing camera attached to a computer, can be interpreted as movement and mirrored in virtual reality

Using gestures in virtual reality empowers the experiencer with the ability to physically influence the experience e.g. a swing of the arm could be mirrored through an avatar in the virtual world as part of a boxing game.

Gestures that are directly reflected in the virtual world also help to enforce a sense of agency, as well as contributing directly to active presence and embodied presence.
