Abstract

We will discuss the characteristics of the Head Mounted Display (HMD) using Holographic Optical Element (HOE) in this paper. We have already proposed that using the HOE we could realize the see-through HMD, that is to say the binocular stereoscopic display. This time we evaluate the influence on the human vision system regarding the optical characteristics of the HOE. The HMD using HOE we proposed so far is the Maxwellian View which is the direct projection on the human retina. When we see something by Maxwellian View, we don't need the focusing of the crystalline lens (ocular accommodation) because the depth field is extremely wide. Therefore our binocular crystalline lens will focus at the vergence point when the Maxwellian View is used on the binocular retina. And we can solve the dissociation of accommodation and convergence which is the basic problem of the conventional HMD. We have made the prototype of HOE which can provide the Maxwellian View on our retina and we have proved that our HOE could separate the binocular images onto left and right eye. In this report, we will introduce the Maxwellian View will change the ocular accommodation optionally according to the convergence when we see the real objects and the virtual objects at the same time. We proved that the HOE which provided the Maxwellian View could solve the dissociation of accommodation and convergence.
