              <br>
              That sounds good. So have I got it correctly?<br>
              <br>
              I need not expect major changes to my content. At least
              basic navigation and interactivity is ensured by existing
              X3D nodes like "NavigationInfo", "Viewpoint",
              "ProxiSensor", "TouchSensor", "PlaneSensor" and so on.<br>
            </div>
          </blockquote>
          <p><br>
          </p>
          <p>There is nothing in X3D that allows or requires HMD-like
            navigation. That would need to be an extension provided by
            the viewing application. Also note that TouchSensor and
            PlaneSensor are pointing-device sensors. For this to work
            (correctly) there must be something that functions as a
            pointing device (e.g., mouse, wand, etc.) and the software
            needs to recognize it. <br>

          <p>In most cases you will need to do scripting when
            interacting with various sensor nodes. You usually want to
            do someone far more complex than can be done by sending
            events to various nodes. Protyping is frequently done for
