PROJECT TITLE :

Monitoring Dietary Behavior with a Smart Dining Tray

ABSTRACT:

In this text, the authors investigate a brand new source of data for dietary monitoring: pressure distribution on the surface beneath dining plates. Pressure sensing has been used to consider the burden of the eaten food. The core idea behind their work is that dynamic pressure data will conjointly be used to distinguish between numerous cutlery-related activities, like cutting, poking, stirring, or scooping. The authors show how to identify such individual actions in continuous datastreams, assign them to specific containers (main plate, salad bowl), count them (how many bites taken), and relate them to completely different abstract food classes. They contemplate two sensing modalities: (1) textile pressure-sensor matrix technology facilitating a "good tablecloth* pair of; that appears and feels sort of a commonplace tablecloth however provides detailed info on the spatial and temporal pressure; and (a pair of) commonplace force sensitive resistor (FSR) sensors placed underneath a rigid tray. They additionally present the results of a new, comprehensive study with 10 subjects, every of whom consumed a total of eight meals chosen from seventeen doable main dishes with six potential side dishes; results show an average accuracy of up to ninety four p.c. This article is part of a special issue on pervasive food.
