Abstract

This invention is a device and system for monitoring a person'"'"'s food consumption comprising: a wearable sensor that automatically collects data to detect eating events; a smart food utensil, probe, or dish that collects data concerning the chemical composition of food which the person is prompted to use when an eating event is detected; and a data analysis component that analyzes chemical composition data to estimate the types and amounts of foods, ingredients, nutrients, and/or calories consumed by the person. In an example, the wearable sensor can be part of a smart watch or smart bracelet. In an example, the smart food utensil, probe, or dish can be a smart spoon with a chemical composition sensor. The integrated operation of the wearable sensor and the smart food utensil, probe, or dish disclosed in this invention offers accurate measurement of food consumption with low intrusion into the person'"'"'s privacy.

Claims

1. A device for monitoring food consumption comprising:

a wearable device that is configured to be worn on a person'"'"'s wrist, hand, finger, arm, neck, and/or head;

a wearable sensor that is part of the wearable device;

wherein this wearable sensor automatically collects primary data that is used to detect an eating event; and

wherein the wearable sensor is an impedance sensor which automatically collects data concerning electromagnetic energy emitted transmitted through the person'"'"'s body or a spectroscopic sensor which automatically collects data concerning light energy reflected from the person'"'"'s body or absorbed by the person'"'"'s body;

a hand-held portable food probe that is a removable part of the wearable device;

wherein the food probe when removed from the wearable device is in optical communication with food, wherein this food probe collects secondary data that is used to analyze the chemical composition of food;

wherein the person is prompted to collect secondary data when (a) an eating event is detected based on primary data and (b) secondary data concerning the eating event has not yet been collected; and

wherein secondary data is collected from one or more spectroscopy sensors that are part of, or attached to, the food probe; and

a data analysis component, wherein this component analyzes data collected by the food probe to estimate the types of foods, ingredients, nutrients, and/or calories that are consumed by the person.

2. The device in claim 1 wherein the wearable sensor is worn on a person'"'"'s wrist, hand, finger, or arm.

3. The device in claim 1 wherein the wearable sensor is part of an electronically-functional wrist band or smart watch.

4. The device in claim 1 wherein the person is prompted to use the food probe when data collected by the wearable sensor indicates a probable eating event and the person does not start using the food probe for this probable eating event before a selected length of time after the start of the probable eating event.

5. The device in claim 1 wherein the person is prompted to use the food probe when data collected by the wearable sensor indicates a probable eating event and the person does not start using the food probe for this probable eating event before a selected quantity of eating-related actions occurs during the probable eating event.

6. The device in claim 1 wherein the person is prompted to use the food probe when data collected by the wearable sensor indicates a probable eating event and the person does not use the food probe throughout the entire probable eating event.
