Food and branding research groups have leveraged illusions to alter individuals perception of serving size, resulting in the individuals serving themselves smaller food portions. One method is using smaller plates or serving utensils, which causes individuals to serve smaller portions of food. This is due to a perception bias that causes individuals to perceive that there is more food on the plate due to the amount of surface area covered or that they have served more. By leveraging one of these illusions we built a persuasive technology that create the illusion that there is more food on a plate than there actually is, which could influence how much food users serve themselves.
