Focus depth cues, a wide field of view, and ever-higher resolutions all present major hardware design challenges for near-eye displays. Optimizing a design to overcome one of these challenges typically leads to a trade-off in the others. We tackle this problem by introducing an all-in-one solution – a new wide field of view gaze-tracked near-eye display for augmented reality applications. The key component of our solution is the use of a single see-through, varifocal, deformable membrane mirror for each eye 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 which is determined by the gaze tracker. The benefits of using the membranes include wide field of view (100° diagonal) and fast depth switching (from 20 cm to infinity within 20 ms). Our subjective experiment verifies the prototype and demonstrates its potential benefits for near-eye see-through displays.

| After working in VFX and animation for 5 years on such films as Maleficent and Wreck-It Ralph, David set out to make the next Augmented Reality display by returning to school and getting a PhD from UNC-Chapel Hill.  Now in his 3rd year of grad school, he is still pursuing that quest while wrangling his 2 sons with help from his lovely wife. Outside the lab he enjoys triathlon, tabletop games and the occasional fantasy novel.
