Estimation of psychophysiological state during HDR contents viewing

Abstract

We experimentally estimated of psychophysiological state during high and standard dynamic ranges contents viewing on a 58-inch 4K TV. As the measurements items, subjectivity assessment, blinking rates, heart rate variability （the level of sympathetic nerve activity: LF/HF）, near-infrared spectroscopic (NIRS) topography were adopted. The results showed that the scores for “presence,” “impact,” “dynamic,” “feeling of depth,” and “high quality,” when viewing 4K-HDR video content were significantly higher than those for 4K-SDR content. Moreover, LF/HF, representing sympathetic nervous system activities, when viewing 4K-HDR video content, was significantly lower than those for 4K-SDR content.
