Effectiveness of Kansei model in Healthy Eating Habits Support System

We verify the performance of the Kansei model in the Healthy Eating Habits Support System (HEHSS). In a previous study, we reported HEHSS, which considers user taste and health. In HEHSS, an NPD Kansei model expresses user taste. The model expresses P (Positive: like) taste, N (Negative: dislike) taste, and D (Don´t care: neutral) taste for all items that make up recipes. The model then evaluates recipes on behalf of the user. To consider user taste, the NPD Kansei model must express user taste appropriately. However, in our previous study, we did not confirm the effectiveness of expressing user taste with the NPD Kansei model. Here, we verify the effectiveness of the model by performing an evaluation experiment using real users. The experimental results show that the NPD Kansei model is effective for expressing user taste.
