(A) The eMagin z800 3D head-mounted display (HMD); head-tracking enables immersive viewing of each scene through the turning of one’s head to look around and 3D presentation allows for depth perception.

Though screenshots are 2D, the actual scenes were presented in stereographic 3D through the HMD shown in A; each illustration represents only a portion of the entire scene, as each could be viewed immersively by turning one’s head or body to look left, right, up or down.
