Abstract / Description: 

With the goal of registering dynamic synthetic imagery onto the real world, Ivan Sutherland envisioned a fundamental idea to combine digital displays with conventional optical components in a wearable fashion. Since then, various new advancements in the display engineering domain, and a broader understanding in the vision science domain have led us to computational displays for virtual reality and augmented reality applications. Today, such displays promise a more realistic and comfortable experience through techniques such as lightfield displays, holographic displays, always-in-focus displays, multiplane displays, and varifocal displays. In this talk, as an Nvidian, I will be presenting our new optical layouts for see-through computational near-eye displays that is simple, compact, varifocal, and provides a wide field of view with clear peripheral vision and large eyebox. Key to our efforts so far contain novel see-through rear-projection holographic screens, and deformable mirror membranes. We establish fundamental trade-offs between the quantitative parameters of resolution, field of view, and the form-factor of our designs; opening an intriguing avenue for future work on accommodation-supporting augmented reality display.


Kaan Akşit received his B.S. degree in electrical engineering from Istanbul Technical University, Turkey in 2007, his M.Sc. degree in electrical power engineering from RWTH Aachen University, Germany in 2010, and his Ph.D. degree in electrical engineering at Koç University, Turkey in 2014. In 2009, he joined Philips Research at Eindhoven, the Netherlands as an intern. In 2013, he joined Disney Research, Zurich, Switzerland as an intern. His past research include topics such as visible light communications, optical medical sensing, solar cars, and auto-stereoscopic displays. Since July 2014, he is working as a research scientist at Nvidia Corporation located at Santa Clara, USA, tackling the problems related to computational displays for virtual and augmented reality.
