Abstract :
This paper presents a proposal for a novel evaluation method to extract personal preferences implicitly using near-infrared spectroscopy (NIRS), a new technique for measuring brain blood flows. Eight subjects were asked to evaluate food pictures of two kinds mentally and decide which they preferred. The NIRS signals were observed during their decision-making and the differences of the brain blood flows were analyzed based on personal preferences. Experimental results demonstrated the potential of NIRS methods to extract personal preferences implicitly.
