2016 Poster Sessions : Tackling the Vergence-Accommodation conflict with Lightfields and Monovision

Student Name : Robert Konrad

Research Areas: Graphics/HCI
Authors: Robert Konrad, Vasanth Mohan, Fu-Chung Huang

Emerging virtual reality (VR) displays must overcome the prevalent issue of visual discomfort to provide high-quality and comfortable user experiences. In particular, the mis-match between vergence and accommodation cues inherent to most stereoscopic displays has been a long standing challenge. We evaluate several display modes that have the promise to mitigate visual discomfort caused by the vergence-accommodation conflict, and improve comfort as well as performance in VR environments. In particular, we explore monovision as an unconventional mode that accommodates each eye of the observer at different depths. While this technique is common practice in ophthalmology, we are the first to test its effectiveness for VR applications with a custom built focus-tunable display. We will also present the light field stereoscope first showed at SIGGRAPH 2015, which provides accurate focus cues for the user hence reducing the vergence-accommodation conflict.

Robert Konrad is a PhD student in the Stanford Computational Imaging group led by Professor Gordon Wetzstein. He is investigating using focus-tunable optics for the purpose of alleviating the vergence-accommodation conflict in near-eye displays.

Vasanth Mohan is currently a masters student in Electrical Engineering and finished his undergraduate degree in Computer Science in 2015 from Stanford. He is very passionate about virtual reality technologies and is excited about all of the challenges this new medium faces.
