Adaptive dynamic refocusing: toward solving discomfort in virtual reality

We present an approach for eliminating the vergence-accommodation conflict, a fundamental cause of discomfort in today's Virtual Reality. We replace traditional lenses in a head-mounted display with a focus-adjustable optical system which provides accommodation cues consistent with the true depth of an observed object. In addition, we take into account the eyeglasses prescription of the user to enable the use of Virtual Reality without eyeglasses. We integrate our system into a commercial headset and demonstrate that solving the vergence-accommodation is possible in a compact form factor without affecting the resolution.
