TransFork

When people eat, the taste is very complex and be influenced easily by other senses. Such as visual, olfactory, and haptic, even past experiences, can affect the human perception, which in turn creates more taste possibilities. We present TransFork, an eating tool with olfactory feedback, which augments the tasting experience with video see-through head-mounted display. Additionally, we design a recipe via preliminary experiments to find out the taste conversion formula, which could enhance the flavor of foods and change the user perception to recognize the food. In this demonstration, we prepare a mini feast with bite-sized fruit, the participants use the TransFork to eat food A and smell the scent of food B stored at the aromatic box via airflow guiding. Before they deliver the food to their mouth, the head-mounted display augmented the color of food B on food A by the QR code on the aromatic box. With this augmented reality techniques and the recipe, the tasting experience could be augmented or enhanced, which is a potential approach and could be a playful used for eating.
