First Claim
Patent Images
1. A wearable device for food identification and quantification comprising:
- a camera which takes pictures of nearby food, wherein these food pictures are analyzed in order to identify the types and quantities of food;
a light-emitting member which projects a light-based fiducial marker on, or in proximity to, the nearby food as an aid in estimating food size;
a spectroscopic optical sensor, wherein this spectroscopic optical sensor collects data concerning light that is reflected from, or has passed through, the nearby food and wherein this data is analyzed to identify the types of food, the types of ingredients in the food, and/or the types of nutrients in the food;
an attachment mechanism, wherein this attachment mechanism is configured to hold the camera, the light-emitting member, and the spectroscopic optical sensor in close proximity to the surface of a person'"'"'s body; and
an image-analyzing member which analyzes the food pictures.

Abstract
This invention is a wearable spectroscopic device, such as a spectroscopic finger ring, for compositional analysis of food or other environmental objects. This device can project light as a fiducial marker to better estimate object size. This device can include a laser pointer which is directed toward an object to guide spectroscopic analysis of the object. Advantages over hand-held spectroscopic sensors include: convenience; subtlety of use; activation based on monitoring of body motion and/or hand gestures; and continuous proximity to hand-held food during eating.
