According to such results, if one were to modify the visual appearance of a food, it might be possible to eliminate, or at the very least to modify, children’s food dislikes based on the latter’s appearance. Similarly, those children presented with a visually-familiar fruit before a novel one show a greater willingness to try the novel fruit as compared to those children who were only exposed to the novel fruit 17. Those children who have been exposed to pictures of novel foods, or actual foods, typically exhibit a greater willingness to try them 8, 15, 16. Therefore, the appearance of novel food can potentially exert a significant influence over people’s food intake by helping to reduce food neophobia and hence possibly facilitating food acceptance. Crucially, neophobia has been shown to reduce the intake of fruits, vegetables, and meats in children 12– 14. Neophobia, or the “fear of something new”, is an adaptive trait that typically peaks between the ages of two and five years of age. Relevant here, visual exposure to a novel food has been shown to be a particularly effective means of introducing new foods to children 12, 13. Moreover, it may also be possible to improve the palatability of food, such as in the case of hospital foods 10, 11, or in those diet foods which intrinsically have little taste/flavour 12. If the visual appearance of food can be modified at will, we may be able to control people’s appetite. In fact, well before a food is consumed, its appearance properties help to set expectations concerning the taste, flavour, and palatability of the food which ultimately affect its acceptance and thereafter its consumption 9. Additionally, visual appearance cues can trigger the desire to eat 5– 8. The visual appearance of food and drink is also very important as far as assessing its freshness is concerned 2– 4. ![]() As Apicius, the Roman gourmand, once said “We eat first with our eyes” 1. Generally-speaking, our choice of which foods to purchase and/or consume is determined by visual cues (i.e., by what we see). The novel food modification method and system outlined here can therefore potentially be used to control the taste/flavour of different foods crossmodally by means of modifying their appearance properties (specifically the SD of the luminance distribution while keeping other aspects of image statistics constant), and can do so in real time, without the need for food markers. expected moistness, wateriness and deliciousness), but also the actual taste properties on sampling the food itself. Manipulating the SD of the luminance distribution affected not only the expected taste/flavour of the food (e.g. Participants looked at a piece of Baumkuchen (Experiment 1) or a spoonful of tomato ketchup (Experiment 2) having different luminance distributions and evaluated the taste on sampling the food. We investigated the effects of changing the luminance SD distribution of Baumkuchen (a German baked cake) and tomato ketchup on visual perception, flavour expectations, and the ensuing taste experience. Instead, the approach outlined here was used to change the SD of the luminance distribution of the food while keeping the chromaticity, the average luminance, and the skewness constant. Importantly, this form of dynamic image manipulation does not change the colour on the food (which has been studied extensively previously). We developed a novel AR system capable of modifying the luminance distribution of foods in real-time using dynamic image processing for simulating actual eating situations. We report two experiments designed to investigate how the standard deviation (SD) of the luminance distribution of food images influences the perceived visual texture and the taste/flavour experience by using the latest Augmented Reality (AR) technology. ![]() We’re not sure which is more disgusting: getting the girls to drink the semen or what it took to extract said semen in the first place.What we taste is affected by what we see, and that includes the colour, opacity, and shape of the food we consume. “What I ended up doing was vomiting in my glass, and just drank that. ![]() And it has a little hint of hay.” She explained that she and her sister had 15 minutes to down the beverages, and if they vomited, they would have to start over. ![]() Not to be denied their well-deserved glory, however, the twins took to a different set of airwaves and called in to Tampa radio’s The Cowhead Show to describe the process of guzzling the filth. NBC decided that having two young women consume mugs of urine and semen, both of which had been left out in the sun for hours, was just a tad too much for the average American’s sensibilities. Donkey SemenThough twins and Fear Factor contestants Brynne and Claire Odioso are now possibly the only two people on the planet who have downed mugs of donkey semen, the deplorable act in question never hit the airwaves.
