This allows the eye's lens to naturally focus at different depths within the reproduced volume. | Research using [[lenslet array]]s, parallax barriers, holographic optical elements, super-multi-view displays. | Potentially provides true continuous focus cues without eye-tracking. Challenges include extremely high resolution and bandwidth requirements, computational complexity, limited field of view, and tradeoffs between spatial and angular resolution. | ||

| Aims to fully reconstruct the wavefront of light from the virtual scene using diffraction patterns generated by [[Spatial light modulator|spatial light modulators]]. | Research by Microsoft Research, VividQ, Light Field Lab. | Theoretically the ultimate solution, providing all depth cues including accommodation correctly. Challenges include high computational cost ("speckle" noise), limited field of view, and hardware complexity for real-time, high-quality HMDs. | | Aims to fully reconstruct the wavefront of light from the virtual scene using diffraction patterns generated by [[Spatial light modulator|spatial light modulators]]. | Research by Microsoft Research, [[VividQ]], Light Field Lab. | Theoretically the ultimate solution, providing all depth cues including accommodation correctly.
