The Effect of a High-Resolution 4K Tablet on Physiological and Psychological State While Viewing Various Types of Content
We experimentally investigated the effects of using a high-resolution 4K tablet on physiological and psychological states while viewing various types of content. The results showed the scores for “precise–coarse,” “feeling of invigoration–no feeling of invigoration” and “enjoyable–boring” when viewing 4K scenic content to be significantly higher than those for 2K scenic content. Moreover, NIRS values, an index of nervous system activity, during viewing tests of 4K scenic content, were significantly higher for 4K content than for 2K content.
