Meal-time and duration monitoring using wearable sensors

The experiments were carried out on 14 healthy subjects wearing the proposed system. In each experiment session, the subjects were asked to have lunch, drink water, rest and talk. The subjects were asked to press a button for each swallow, and the whole experiment process was video recorded. The push button and video information were used as a ground truth for verification purposes. Through extensive experimentation in a semi-controlled setting, it was shown that the system is able to detect mealtime with high accuracy.
