Behavior tracking technology (e.g., step count and food intake) is becoming increasingly popular due to its potential to improve the users' behaviors. With this trend, researchers are exploring new tools to help individuals achieve mindful eating. Thus far, we have explored a variety of ways to design novel interactive techniques to regulate eating habits by increased mindfulness. We systematically reviewed existing digital interventions and persuasive technology for improving the way one eats. Further, based on this review, we generated a design framework for designers of eating intervention technologies. The developed framework was validated through a parallel analysis, and tested in a design brainstorming session. Based on this framework, a smart utensil prototype was developed to detect excessively rapid eating behavior. This smart utensil or a smart fork is a prototype designed to detect eating movements, and estimate the weight of each bite. As a result, our smart fork can recognize when a user is eating too quickly or too slowly. As a next step, we plan to explore novel feedback mechanisms for fast eaters in real life setting.
