Development of Calorie Tracking Algorithm for Children and Comparison with Commercialized Product †

In this study, we developed an appropriate calorie tracking algorithm for children and compared it with the current commercial product. The results of the developed algorithm showed 94.2% accuracy in the classification of intermittent activities: sitting down, standing up, turning around and jumping; and 92.9% accuracy in the classification of continuous activities: walking, running, stair climbing, and jumping rope. This comparison shows that the developed algorithm outperforms the commercialized one and shows it is suitable for actual use of children. This study provides new activity monitor algorithm for children’s self-management.
