    Rendering Focus Cues in Head-Mounted Displays for Virtual and Augmented Reality Displays

    Abstract(s): 

    A head-mounted display (HMD), also known as head-worn display, is one of the key enabling technology for the emerging virtual reality (VR) and augmented reality applications. Among the many challenges of developing HMDs, minimizing visual discomfort is one of the key obstacles. One of the key contributing factors to visual discomfort is the lack of the ability to render proper focus cues in HMDs to stimulate natural eye accommodation responses, which leads to the well-known problem of vergence-accommodation conflict. In this colloquium address, I will review the various technical approaches toward enabling focus cues in HMDs, summarize our recent advancements in developing HMD technologies, especially our recent progress in head-mounted light field displays for rendering correct focus cues.

    Speaker Bio(s): 

    Hong Hua, Ph.D., is a Professor of Optical Sciences at the University of Arizona. Prior to joining the UA faculty in 2003, Dr. Hua was an Assistant Professor with the University of Hawaii at Manoa in 2003, was a Beckman Research Fellow at the Beckman Institute of University of Illinois at Urbana-Champaign between 1999 and 2002, and spent 10 months as a post-doc at the University of Central Florida. Dr. Hua received her Ph.D. degree in Optical Engineering from the Beijing Institute of Technology in China in 1999.  Dr. Hua’s current research focuses on optical technologies enabling advanced 3D displays, especially head-mounted display technologies for virtual reality and augmented reality applications, and microscopic and endoscopic imaging systems for medicine.  She is an SPIE Fellow and OSA senior member. Dr. Hua and her students shared several “Best Paper” awards in various IEEE, SPIE and SID conferences.
