Wearable Device and System for Nutritional Intake Monitoring and Management
This invention is a wearable device which helps a person to track their food intake as part of a system for nutritional intake monitoring and management. This invention can be embodied in a smart watch and/or wrist band with a camera, a display and/or camera viewfinder, a spectroscopic sensor, and an eating detector. The eating detector can be an accelerometer, a gyroscope, a magnetometer, a microphone, or an EMG sensor. The camera and/or the spectroscopic sensor can be automatically activated when the person eats food, but otherwise remain off to help maintain privacy.
1 . A wearable device for tracking food intake comprising:
a band worn on a person's wrist and/or arm;
a camera on the band, wherein the camera records food images, wherein the food images are analyzed to identify food types and quantities;
a primary display on the band, wherein the primary display is centered on a first location on the circumference of the band, wherein the camera is centered on a second location on the circumference of the band, wherein the second location is between 60 to 110 degrees around the band circumference away from the first location in a first direction, and wherein the first direction can be clockwise;
a camera viewfinder on the band, wherein the camera viewfinder displays the food images recorded by the camera, wherein the camera viewfinder is centered on a third location on the circumference of the band, and wherein the third location is between 70 and 110 degrees around the band circumference away from the first location in a second direction which is opposite the first direction, and wherein the second direction can be counter-clockwise;
a spectroscopic sensor on the band, wherein the spectroscopic sensor further comprises a light emitter and a light receiver, wherein the light emitter emits light rays toward food, wherein the light receiver receives the light rays after the rays have been reflected by the food, and wherein the light rays reflected by the food are analyzed to identify food types and/or composition; and
an eating detector on the band which collects data which is analyzed to detect when the person is eating, wherein the eating detector further comprises one or more components selected from the group consisting of: an accelerometer, a gyroscope, a magnetometer, a microphone, and an EMG sensor.
2 . A wearable device for tracking food intake comprising:
a band worn on a person's wrist and/or arm;
a camera on the band, wherein the camera records food images, wherein the food images are analyzed to identify food types and quantities;
a primary display on the band, wherein the primary display displays food images recorded by the camera, wherein the primary display is centered on a first location on the circumference of the band, wherein the camera is centered on a second location on the circumference of the band, and wherein the second location is between 160 to 200 degrees around the band circumference away from the first location;
a spectroscopic sensor on the band, wherein the spectroscopic sensor further comprises a light emitter and a light receiver, wherein the light emitter emits light rays toward food, wherein the light receiver receives the light rays after the rays have been reflected by the food, and wherein the light rays reflected by the food are analyzed to identify food types and/or composition; and
an eating detector on the band which collects data which is analyzed to detect when the person is eating, wherein the eating detector further comprises one or more components selected from the group consisting of: an accelerometer, a gyroscope, a magnetometer, a microphone, and an EMG sensor.
3 . A wearable device for tracking food intake comprising:
a band worn on a person's wrist and/or arm;
a primary housing on the band;
a flip-up display which flips, pivots, rotates, tilts, and/or pops up from the primary housing;
a camera on the band, wherein the camera records food images, wherein the food images are analyzed to identify food types and quantities, wherein the flip-up display serves as a viewfinder for the camera, wherein the primary housing is centered on a first location on the circumference of the band, wherein the camera is centered on a second location on the circumference of the band, and wherein the second location is between 70 and 110 degrees around the band circumference away from the first location;
a spectroscopic sensor on the band, wherein the spectroscopic sensor further comprises a light emitter and a light receiver, wherein the light emitter emits light rays toward the food, wherein the light receiver receives the light rays after the rays have been reflected by the food, and wherein the light rays reflected by the food are analyzed to identify food types and/or composition; and
an eating detector on the band which collects data which is analyzed to detect when the person is eating, wherein the eating detector further comprises one or more components selected from the group consisting of: an accelerometer, a gyroscope, a magnetometer, a microphone, and an EMG sensor.
