Increasingly, people are replacing soft drinks with natural fruit juices, since soft drinks usually contain excessive sugar and little nutrition. This project introduces a multimodal digital taste control system ‘D’Licious Vessel’ and the respective prototypes. The goal is to provide a digital solution to health concerns regarding overuse of sugar in our daily drinks by decreasing the natural sourness. The system applies gentle electrical signals to a person’s tongue to trigger different taste sensations and improve the taste of drinks digitally without involving consumption of actual chemicals. We conducted user studies in a public setting to collect the experimental data and to find the system’s effectiveness in improving the taste of lemon juice. During the study, participants were provided with lemon juice and asked to compare the taste difference while drinking with different settings of the taste stimulation prototype. Their opinions for different prototype designs are recorded and discussed.

Working at CUTE Center at NUS since 2014 summer, I engaged in three programs for searching more about the Interactive Digital Media. I am conducting user study of Digital Taste. Digital Taste enables people to experience taste sensations digitally and arms to promote a healthier lifestyle by replacing the unnecessary amount of condiments in our daily consumption. I designed the bottle prototype with function as hydration. During our showcase at Singapore Art Science Museum, we conducted a larger user. We chose six fixed modes and combinations for testing the participants. From the overall user study results, we may conclude that the prototype can improve the drinking experience for some users.  Our challenge is how to customize people taste sensation and create a new design for making the simulation more natural.

“Not only do the thing right but also do the right thing” goes one of my favorite sayings. I have an industrial engineering background could inspire me to approach the design issue from a broader and more creative perspective. I believe that design should be integrated with the content of culture and therefore make people communicate with nature in multiple ways.
