Abstract
The present invention relates to a device that can be used in individual weight control protocols that is capable of detecting in real time information with regard to number of bites taken, time between bites, and so forth. The weight control device can detect bites through motion detection via a sensor worn on the wrist or hand of a user. The device can include notification capabilities that can alert a user as to excessive eating speed, excessive amounts of food intake, and the like so as to provide immediate feedback for purposes of weight control.
Claims36
A device for determining that a bite of food has been taken by a subject, the device comprising:
- a sensor that monitors a positive roll velocity and a negative roll velocity of a hand, arm, wrist, or any combination thereof of a subject;
- and
- an electronic processor for receiving raw data concerning the positive roll velocity and the negative roll velocity of the hand, arm, wrist, or any combination thereof of the subject from the sensor, the electronic processor carrying out data manipulation to form processed data, the processed data including determination that the positive roll velocity exceeds a threshold positive roll velocity and the negative roll velocity exceeds a threshold negative roll velocity and that a pause of between about 0.5 seconds and about 10 seconds exists between the positive roll velocity and the negative roll velocity to determine that a bite of food has been taken by the subject.
A device for determining that a bite of food has been taken by a subject, the device comprising:
- a sensor that monitors at least a positive roll motion and a negative roll motion of a hand, arm, wrist, or any combination thereof of a subject;
- and
- an electronic processor for receiving raw data concerning at least the positive roll motion and the negative roll motion of the hand, arm, wrist, or any combination thereof of the subject from the sensor, the electronic processor carrying out data manipulation on the raw data to form processed data, the processed data including determination that a bite of food has been taken by the subject.
A method for determining that a bite of food has been taken by a subject, the method comprising:
- sensing raw data concerning positive roll velocity and negative roll velocity of a hand, arm, wrist, or any combination thereof of a subject;
- electronically processing the raw data with a processor to develop processed data, the processed data comprising a pattern of motion, the pattern of motion including
- (a) a positive roll of the hand, arm, wrist, or any combination thereof of a subject that is determined when the positive roll velocity exceeds a threshold positive roll velocity,
- (b) a negative roll of the hand, arm, wrist, or any combination thereof of a subject that is determined when the negative roll velocity exceeds a threshold negative roll velocity;
- and
- (c) a pause of between about 0.5 seconds and about 10 seconds between (a) and (b), wherein upon recognition by the processor of the pattern of motion, the processor registers that a bite of food has been taken by the subject.
