Recent work in Automated Dietary Monitoring (ADM) has shown promising results in eating detection by tracking jawbone movements with a proximity sensor mounted on a necklace. A significant challenge with this approach, however, is that motion artifacts introduced by natural body movements cause the necklace to move freely and the sensor to become misaligned. In this paper, we propose a different but related approach: we developed a small wireless inertial sensing platform and perform eating detection by mounting the sensor directly on the underside of the jawbone.

In this work, two algorithms are proposed for passive assessment of pulmonary condition: one for detection of obstructive pulmonary disease and the other for estimation of the pulmonary function in terms of FEV_1/FVC ratio, which is an established clinical metric. This work presents a meaningful milestone towards the passive assessment of pulmonary functions from spontaneous speech collected from a mobile phone.

We propose an approach that leverages off-the-shelf activity tracker to detect drinking events. Here, we also apply an adaptive windowing approach in the analysis to capture the wide distribution of drinking durations.

FlashBite is a wearable necklace that continuously tracks the jaw motion using an infrared proximity sensor. In this paper, we talk about the application of FlashBite for dietary monitoring.
