Much attention has been paid recently to near eye displays (NED), specifically virtual reality (VR) and augmented reality (AR) viewers, particularly in the area of consumer electronics. And, as with many new technologies, the initial rush of enthusiasm and high demand has sometimes outpaced the ability of manufacturers to thoroughly characterize their products. Indeed, some NED system manufacturers have had no objective, quantitative way to test the quality of their displays, other than to have human operators view them subjectively, and say whether or not a given unit “looks good.”
