Abstract

As the era of virtual reality (VR) and augmented reality (AR) dawns, displays are being confronted with a new set of challenges. Unlike the requirements for conventional displays, VR/AR asks displays for the level of performance such that the viewer can believe what s/he sees is real in every sense. The new requirements include not only the well-known properties for displays (frame rate, resolution, field of view, and bit depth) but also properties which had been rather unimportant but will be critical (system latency and pixel persistence). Accurate spatial representation is crucial in VR/AR, which adds more requirements such as stereoscopic views, realistic focal cues, and precise spatial registration of the images. On top of all these requirements, fast cooperation between displays and other devices (eye and head tracker, sound system, etc.) is vital for ultimate realism. Meeting all these requirements is very hard despite the remarkable advance of modern technology. Understanding human perception is the key to solving this problem or to finding the best available solution. In this talk, I will present an overview of the requirements of displays for VR/AR with the related properties of human perception. I will also introduce several attempts that overcame the technical challenges by exploiting the properties of human perception.
