Smart Glasses and Wearable Systems for Measuring Food Consumption
This invention is a wearable device or system for measuring food consumption using multiple sensors which are incorporated into smart glasses, a smart watch (or wrist band), or both. These sensors include one or more cameras on the smart glasses, on the smart watch, or both which record food images when eating is detected by a motion sensor, an EMG sensor, and/or a microphone. The smart watch (or wrist band) can also include a spectroscopic sensor to analyze the molecular and/or nutritional composition of food.
1 . Smart eyewear for measuring food consumption comprising:
an eyewear frame worn by a person;
a camera on the eyewear frame which records food images when activated; and
a chewing sensor on the eyewear frame which detects when the person eats, wherein the camera is activated to record food images when data from the chewing sensor indicates that the person is eating.
2 . A smart watch or wrist band for measuring food consumption comprising:
a smart watch or wrist band worn by a person;
a motion sensor on the smart watch or wrist band;
a camera on the smart watch or wrist band, wherein the camera is activated to record food images when data from the motion sensor indicates that the person is eating; and
a spectroscopic sensor on the smart watch or wrist band which analyzes the molecular and/or nutritional composition of food.
3 . A wearable system for measuring food consumption comprising:
an eyewear frame worn by a person;
a chewing sensor on the eyewear frame which detects when the person eats;
a smart watch or wrist band worn by the person;
a motion sensor on the smart watch or wrist band;
a first camera on the eyewear frame which records food images when activated, wherein the first camera is activated to record food images when data from the chewing sensor and data from the motion sensor indicate that the person is eating; and
a second camera on the smart watch or wrist band which records food images when activated, wherein the second camera is activated to record food images when data from the chewing sensor and data from the motion sensor indicate that the person is eating.
