DEVICE AND METHOD FOR MONITORING FOOD INTAKE
First Claim
1. A device for monitoring food intake by a user to whom the device is attached, the device comprising:
- at least one camera to acquire a series of images of at least a partial view of a manipulable limb of the user;
a processor configured to apply a probabilistic model to determine based on the series of images if a motion of the limb corresponds to at least one predetermined gesture that is indicative of taking a bite, and to update a recorded sequence of events when the motion is determined to correspond to said at least one predetermined gesture; and
a signaling unit that is operable by the processor to produce a signal that is sensible by the user, wherein the signal is indicative of the updating of the sequence of events.

Abstract
A device for monitoring food intake by a user to whom the device is attached includes at least one camera to acquire a series of images of at least a partial view of a manipulable limb of the user. A processor is configured to apply a probabilistic model to determine based on the series of images if a motion of the limb corresponds to at least one predetermined gesture that is indicative of taking a bite. A recorded sequence of events is updated when the motion is determined to correspond to a predetermined gesture. A signaling unit is operable by the processor to produce a signal that is sensible by the user, the signal being indicative of the updating of the sequence of events.

13. A method for monitoring food intake by a user, the method comprising:
-
acquiring using a camera that is attached to the user a series of images of a manipulable limb of the user; analyzing the acquired images, using a processor, to identify a motion of the limb; applying by the processor a probabilistic model to calculate a probability that the identified motion corresponds to at least one predetermined gesture that is indicative of taking a bite; using the probability by the processor to determine if the identified motion is indicative of taking a bite during a time segment; and when the identified motion is determined by the processor to be indicative of taking a bite, updating a sequence of events and generating a signal. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20)
