On the other hand, reduced spatial resolution was the primary limitation of this device. Lanman and Luebke (2013) indicated that the resolution is proportional to the ratio of the microlens focal length to the distance of the display from the eye. This means that a compact form factor, while desirable, results in a lower resolution. To have a higher resolution means you would have a bigger, bulkier display. Furthermore, they wrote that “practical applications will necessitate manufacturing larger microdisplays with smaller pixel pitches, enabling wide fields of view and high resolutions, respectively.” <ref name=”2”></ref>

The near-eye light field stereoscope prototype of 2015 also addresses the accommodation-convergence conflict that leads to motion sickness, resulting in a more natural and flexible experience. In this case, the gadget uses two layers of LCD separated by approximately 5 millimeters. These send an entire “4D” light field of images so the eye can set focus between objects more naturally <ref name=”11”> Pirzada, Usman (2015).

The resolution was also a limitation in this prototype. While the screen resolution was 1280x800, the HMD splits the screen into two halves, making the effective resolution decrease to 640x800 per eye. This is too low for a current setting, but it could be improved in the future since this is still in the prototype stage. Indeed, NVIDIA intends to bring this gadget into the market by 2018. While NVIDIA could be developing the new standard for HMDs, it could also mean that by the time the gadget is released to the market conventional VR makers may have solved the problems related to motion sickness in their own gadgets <ref name=”11”></ref>.
