Visually Manipulating Perceived Food Texture in Projection Mapping

Abstract

Perceived taste and flavor of food are greatly affected by visual information, and manipulating them in projection mapping (PM) has been explored. This paper focuses on another aspect of the gustatory sense‐food texture. We investigate whether perceived food textures can be modified by the perceptually deforming effect in PM. Through a user study, we found that the perceived softness of a pudding could be significantly increased by amplifying the apparent movement of the pudding. Interestingly, other gustatory perceptions unrelated to food textures were not affected. We believe that this result expands the potential of PM-based modulation of gustatory perceptions.
