A method, a system, and a device for navigating in a virtual reality scene, using body parts gesturing and posturing are provided herein. The method may include: projecting a synthetic 3D scene, into both eyes of a user, via a near eye display, so as to provide a virtual reality view to the user; identifying at least one gesture or posture carried out by at least one body part of said user; measuring at least one metric of a vector associated with the detected gesture or posture; applying a movement or action of said user in virtual reality environment, based on the measured metrics; and modifying the virtual reality view so as to reflect the movement or action of said user in the virtual reality environment.
