First Claim
Patent Images
1. A wearable device for identifying food consumption comprising:
- a wearable camera that is configured to be;
part of eyewear;
worn on, in, or around an ear;
part of a necklace or pendant;
or worn on a collar; and
a data processor which uses gesture recognition to analyze the pictures taken by the camera in order to identify when the person is eating—
wherein selected eating gestures are recognized by tracking the configuration and movement of one or more objects selected from the group consisting of;
the person'"'"'s thumb comprising a distal segment and a proximal segment;
the person'"'"'s index finger comprising a distal segment, a middle segment, and a proximal segment;
a portion of food; and
a food-transporting object selected from the group consisting of a fork, spoon, chop stick, drinking glass, beverage can, cup, mug, and bowl.

Abstract
This invention comprises devices and methods which use a wearable camera and gesture recognition in order to identify when a person is eating. Eating-related gestures are recognized by tracking the configuration and movement of a person'"'"'s thumb, a person'"'"'s index finger, a portion of food, and/or a food-transporting object (such as a fork, spoon, chop stick, drinking glass, beverage can, cup, mug, or bowl). These devices and methods can help people to better manage their food consumption, energy balance, and weight.

20. A wearable device for identifying food consumption comprising:
-
a wearable camera that is configured to be;
part of eyewear;
worn on, in, or around an ear;
part of a necklace or pendant;
or worn on a collar; anda data processor which uses gesture recognition to analyze pictures taken by the camera in order to identify when the person is eating—
(a) wherein eating gestures are recognized by creating a virtual model, as seen from the perspective of a virtual camera, comprising one or more objects selected from the group consisting of;
a virtual thumb comprising a distal segment and a proximal segment;
a virtual index finger comprising a distal segment, a middle segment, and a proximal segment;
a virtual portion of food; and
a virtual food-transporting object selected from the group consisting of a virtual fork, spoon, chop stick, drinking glass, beverage can, cup, mug, and bowl; and
(b) wherein the configurations and movements of one or more objects selected from the group consisting of;
the virtual thumb, the virtual index finger, the virtual portion of food, and the virtual food-transporting object as seen from the virtual camera represent, respectively, the configurations and movements of one or more objects selected from the group consisting of;
the person'"'"'s actual thumb, the person'"'"'s actual index finger, an actual portion of food, and an actual food-transporting object as seen from the perspective of the actual wearable camera.
