Paper Abstract

We propose multimodal sensor and algorithm for automatic recognition of a food intake based on glycemic response. Embedding this sensor in a wearable device makes it possible to count number of meals at a given time and to generate personalized statistical pattern of eating habits. This pattern may have significant impact on both personal health care and big-data-driven social engineering. We use near-infrared diffuse reflectance spectroscopy, bioimpedance measurements, and binary classification for non-invasive continuous glucose trend measurements and Fourier transform based time frequency analysis of glycose trends for characterization of eating patterns and prediction of digestive system abnormalities. We tested the sensor in a series of experiments with the certain type of food and achieved 45% average accuracy of a food intake recognition with the random noise level being at 25%.
