    Foveation and (de)focus are two important visual factors in designing near eye displays. Foveation can reduce computational load by lowering display details towards the visual periphery, while focal cues can reduce vergence-accommodation conflict thereby lessening visual discomfort in using near eye displays. We performed two psychophysical experiments to investigate the relationship between foveation and focus cues. The first study measured blur discrimination sensitivity as a function of visual eccentricity, where we found discrimination thresholds significantly lower than previously reported. The second study measured depth discrimination threshold where we found a clear dependency on visual eccentricity. We discuss the study results and suggest further investigation.

    Accommodative depth cues, a wide field of view, and ever-higher resolutions present major design challenges for near-eye displays. Optimizing a design to overcome one of them typically leads to a trade-off in the others. We tackle this problem by introducing an all-in-one solution - a novel display for augmented reality. The key components of our solution are two see-through, varifocal deformable membrane mirrors reflecting a display. They are controlled by airtight cavities and change the effective focal power to present a virtual image at a target depth plane. The benefits of the membranes include a wide field of view and fast depth switching.
