Wearable food consumption monitor
This invention is a wearable system for monitoring a person's food consumption comprising a motion sensor worn on a person's wrist, a camera worn on the person's ear or housed in the person's eyewear, and a data processor which analyzes data from the motion sensor. The camera is automatically triggered to take pictures of food when analysis of data from the motion sensor indicates that the person is eating.
1. A wearable system for monitoring a person's food consumption comprising:
a motion sensor which is configured to be worn on a person's wrist;
an ear-mounted device, wherein the ear-mounted device further comprises a loop which is configured to span from the person's right ear to the person's left ear;
a first camera on the ear-mounted device, wherein the first camera is located on the right side of the person's head;
a second camera on the ear-mounted device, wherein the second camera is located on the left side of the person's head; and
a data processor which analyzes data from the motion sensor, wherein the first camera and the second camera are automatically triggered to record images of food when analysis of data from the motion sensor indicates that the person is eating, and wherein images from first camera and images from the second camera are used to create a three-dimensional model of food.
2. The system in claim 1 wherein the motion sensor is an accelerometer.
3. The system in claim 1 wherein the motion sensor is housed in a wrist watch.
4. The system in claim 1 wherein the motion sensor is housed in a wrist band.
5. The system in claim 1 wherein indication that the person is eating is based on analysis of the acceleration, inclination, twisting, and/or rolling of the person's hand, wrist, and or arm.
6. The system in claim 1 wherein the picture images of food are analyzed to monitor the person's food consumption.
7. A wearable system for monitoring a person's food consumption comprising:
an ear-mounted device, wherein the ear-mounted device further comprises a loop which is configured to span from the person's right ear to the person's left ear;
a microphone on the ear-mounted device;
a first camera on the ear-mounted device, wherein the first camera is located on the right side of the person's head;
a second camera on the ear-mounted device, wherein the second camera is located on the left side of the person's head; and
a data processor which analyzes data from the microphone, wherein the first camera and the second camera are automatically triggered to record images of food when analysis of data from the microphone indicates that the person is eating, and wherein images from first camera and images from the second camera are used to create a three-dimensional model of food.
