Flavor-Videos: Enhancing the Flavor Perception of Food while Eating with Videos

People are typically involved in diferent activities while eating, particularly when eating alone, such as watching television or playing games on their phones. Previous research in Human-Food Interaction (HFI) has primarily focused on studying people's motivation and analyzing of the media content watched while eating. However, their impact on human behavioral and cognitive processes, particularly favor perception and its attributes, remains underexplored. We present a user study to investigate the infuence of six types of videos, including mukbang - a new food video genre, on favor perceptions (taste sensations, liking, and emotions) while eating plain white rice. Our fndings revealed that participants perceived positive emotional changes and reported signifcant diferences in their augmented taste sensations (e.g., spicy and salty) with diferent food-based videos. Our fndings provided insights into using our approach to promote digital commensality and healthier eating (digital augmentation without altering the food), highlighting the scope for future research.
