Title: Building Immersive Virtual Worlds with Multifocal Displays

Abstract: The goal of 3D displays is to replicate all perceptual cues used by the human visual system. Even though most perceptual cues can be replicated by showing 2D images to our eyes, the accommodation cue, or the change of the focal length of our ocular lens, is very difficult to create with today's 3D displays. The inability to support the focusing of our eyes makes the virtual world inauthentic and often results in visual discomfort. In this talk, I will introduce multifocal display, which is a promising solution to create immersive virtual experiences. I will discuss the limitations of existing multifocal displays and demonstrate our solutions to these problems.
