Visual Acuity in Virtual Space

Abstract

How detailed feature of virtual world could be seen by the actual user is an important performance of VR display system, such as Head Mounted Display (HMD). The average or standard user's eyesight in a virtual world could be regarded as a performance index of the VR display system in terms of resolution. This paper aims to show the way to obtain the theoretical value of eyesight from the specifications of components that form an VR display system. This is obtained by synthesizing the total performance of an VR display system's from those of components and by comparing that with standard user's contrast sensitivity function. Through the example estimations, the valid region of the equivalent eyesight from pixel pitch, a new simple conversion from blur size to eyesight were provided.
