Using a mobile device (smartphone, tablet) is a second option to watch a 360°-video. To navigate in the 360°-environment, the user can move the mobile device around. The navigation within the 360°-environment, will automatically adjust and thus correspond to the direction of the mobile device.

Also, one no longer receives external visual information as this headset completely encloses the eyes.

Within the VR headsets there is another distinction between:
