The microlens arrays mounted in front of the displays are used to convert pixels to individual light rays, generating a light field in front of the eye. It allows the viewer to focus at multiple depths and create a field of view of approximately 70 degrees. Users who experimented the prototype during the conference confirmed both aspects. Furthermore, they reported that despite being situated close to the eye, the prototype still provided some sharp images. Nevertheless, the proximity caused some pixel loss due to a decreased spacial resolution. Another interesting aspect of this prototype is that adjustments can be made, at the level of software, to take into account the user’s glasses or contacts prescription. The software is powered by NVIDIA GPUs and OpenGL <ref name=”5”></ref><ref name=”9”></ref>.

NVIDIA, in collaboration with Stanford Computational Imaging, presented a new near-eye display technology that supports focus cues (accommodation and retinal blur) and high image resolution during SIGGRPAH’s 2015 conference (Figure 3). The prototype was based on Wheatstone’s original stereoscope, augmented with modern factored light field synthesis via stacked liquid crystal panels.<ref name=”8”>The Light Field Stereoscope | SIGGRAPH 2015.

A light field is presented to each eye, providing a more natural viewing experience than conventional NEDs. The required field of view is very small (the size of the pupil), and it produces correct or nearly-correct focus cues. These cues are important for diminishing visual discomfort and contributing to comfortable, long-term immersive experiences. The developers of the [[light field stereoscope]] had the main goal of providing a practical, inexpensive display technology that supports focus cues in a wearable form factor <ref name=”7”></ref><ref name=”8”></ref>.
