Abstract

How can we measure ‘ reality ’ ? Though spatial and temporal resolution of display, accuracy of modeling and size of display correlate with reality, they do not fully account reality. I introduce perceptual constancy and brain-information decoding as methods to measure reality perceived by observers. On perceptual constancy, I show an experiment of lightness perception in virtual-reality environment with manipulating depth cues, and discuss the relationship between perceptual constancy and reality. On brain-information decoding, I show an experiment of estimating heading direction with eye-movement from fMRI brain imaging, and propose how to measure reality utilizing brain information.
