Perceptual difference between the discomfort luminance level and the brightness of a head-mounted display (HMD)

A psychophysical experiment was conducted to compare the discomfort luminance level and brightness of a head-mounted display (HMD). The results showed that as size HMD stimulus increased, both decreased, but influence change more dramatic on than brightness. This study provide comfortable for HMDs, adaptation should be considered. However, it cannot predicted in terms
