Abstract

Systems, methods, and computer-readable media are disclosed for dynamic nutrition tracking with utensils. Example methods may include receiving an image of a first food item positioned at a first location and a second food item positioned at a second location, the image comprising location metadata, determining, based at least in part on the image and the location metadata, a first set of coordinates corresponding to a first perimeter of the first location of the first food item, and determining a second set of coordinates corresponding to a second perimeter of the second location of the second food item. Example methods may include determining that a utensil performed a gesture associated with a food consumption event, determining that an origination point of the food consumption utensil at a start of the gesture was within the first perimeter, and identifying a weight measurement of a food portion on the utensil.

Claims

1. A method comprising:

receiving, by one or more computer processors coupled to at least one memory, a first input indicative of an initiation of a food consumption event;

triggering a load cell configured to detect a first weight measurement of a food portion on a food consumption utensil;

triggering, after a predetermined length of time, the load cell to detect a second weight measurement;

determining that a difference between the first weight measurement and the second weight measurement meets or exceeds a food consumption interruption threshold; and

discarding the first weight measurement and the second weight measurement based at least in part on the food consumption interruption threshold.

2. The method of claim 1, further comprising:

triggering, upon determining that the difference meets the food consumption interruption threshold, the load cell to detect a third weight measurement;

determining that the third weight measurement is greater than the second weight measurement;

determining that the food consumption event is complete; and

using the third weight measurement to determine nutritional information of the food consumption event.

3. The method of claim 2, further comprising:

identifying a food item associated with the food portion; and

identifying nutritional information associated with the food item;

wherein the nutritional information of the food consumption event is based at least in part on the nutritional information associated with the food item and the third weight measurement.

4. The method of claim 2, wherein the first weight measurement is greater than the second weight measurement and the third weight measurement is greater than the second weight measurement.

5. The method of claim 1, further comprising:

triggering the load cell to detect a third weight measurement;

determining that the third weight measurement is greater than the second weight measurement;

determining an elapsed time between the third weight measurement and the second weight measurement is less than a minimum food consumption time interval; and

using the third weight measurement to determine nutritional information of the food consumption event.

6. The method of claim 1, wherein the second weight measurement is greater than zero and the first weight measurement is greater than the second weight measurement.

7. A method comprising:

determining, by one or more computer processors coupled to at least one memory, initiation of a food consumption event;

determining a first timestamp at the initiation of the food consumption event;

determining that the food consumption event is complete at a second timestamp;

determining, at a first periodic time interval after the first timestamp, a first weight measurement of a food portion to be consumed;

determining, at a second periodic time interval after the first periodic time interval, a second weight measurement of the food portion to be consumed; and

determining an average weight measurement based at least in part on the first weight measurement and the second weight measurement.

8. The method of claim 7, further comprising:

determining a nutritional content of the food portion based at least in part on the average weight measurement.

9. The method of claim 8, further comprising generating a food item recommendation based at least in part on the nutritional content.

10. The method of claim 7, wherein determining that the food consumption event is complete comprises determining a third weight measurement of the food portion is equal to approximately zero.

11. The method of claim 7, wherein determining that the food portion has been consumed comprises determining that a predetermined length of time has elapsed from the first timestamp.

12. The method of claim 7, wherein determining initiation of a food consumption event comprises:

detecting a motion gesture;

comparing the motion gesture to a set of stored motion gestures;

determining that the motion gesture is within a predefined tolerance of one of the set of stored motion gestures; and

determining that the motion gesture corresponds to a food consumption event.

13. A device comprising:

at least one memory that stores computer-executable instructions;

at least one processor configured to access the at least one memory and execute the computer-executable instructions to;

receive a first input indicative of an initiation of a food consumption event;

trigger a weight measurement device configured to detect a first weight measurement of a food portion on a food consumption utensil;

trigger, after a predetermined length of time, the weight measurement device to detect a second weight measurement;

determine that a difference between the first weight measurement and the second weight measurement meets or exceeds a food consumption interruption threshold; and

discard the first weight measurement and the second weight measurement based at least in part on the food consumption interruption threshold.

14. The device of claim 13, wherein the at least one processor is further configured to access the at least one memory and execute the computer-executable instructions to:

trigger, after determining that the difference meets the food consumption interruption threshold, the weight measurement device to detect a third weight measurement;

determine that the third weight measurement is greater than the second weight measurement;

determine that the food consumption event is complete; and

use the third weight measurement to determine nutritional information of the food consumption event.

15. The device of claim 14, wherein the at least one processor is further configured to access the at least one memory and execute the computer-executable instructions to:

identify a food item associated with the food portion; and

identify nutritional information associated with the food item;

wherein the nutritional information of the food consumption event is based at least in part on the nutritional information associated with the food item and the third weight measurement.

16. The device of claim 14, wherein the first weight measurement is greater than the second weight measurement and the third weight measurement is greater than the second weight measurement.

17. The device of claim 13, wherein the at least one processor is further configured to access the at least one memory and execute the computer-executable instructions to:

trigger the weight measurement device to detect a third weight measurement;

determine that the third weight measurement is greater than the second weight measurement;

determine an elapsed time between the third weight measurement and the second weight measurement is less than a minimum food consumption time interval; and

use the third weight measurement to determine nutritional information of the food consumption event.

18. The device of claim 13, wherein the second weight measurement is greater than zero and the first weight measurement is greater than the second weight measurement.
