“…Additionally, several studies estimated the interests of content involving human behavior [ 19 , 20 ] and personalized saliency (and its prediction) using gaze data [ 21 , 22 , 23 ]. Furthermore, the analysis of behavior, gaze data, and brain activity contribute to the solutions to several tasks, such as brain decoding [ 24 , 25 , 26 , 27 ] and certain applications [ 28 , 29 , 30 , 31 , 32 ]. Onuma et al [ 31 , 32 ] showed that human brain activity calculated from functional near-infrared spectroscopy (fNIRS) is related to the taste of food [ 31 ].…”
