Abstract

Systems and methods for measuring calorie input are described. A calorie measure may be maintained. At least one image of a food item may be captured. The at least one image of the food item may be transmitted to a server. A calories consumed value may be received from the server. The calories consumed value may be determined based at least in part on the at least one image of the food item. The calorie measure may be updated based on the received calories consumed value.

Claims

1. A computer-implemented method for measuring calorie input, comprising:

maintaining a calorie measure;

capturing multiple images of a field of view at a periodic timing interval;

analyzing each image from the multiple images to identify whether an image of the field of view includes a food item;

automatically capturing at least one pre-consumption image and at least one post-consumption image of the food item based at least in part on detecting the food item in the image of the field of view;

transmitting the at least one pre-consumption image and the at least one post-consumption image of the food item to a server;

receiving, from the server, a calories consumed value, wherein the calories consumed value is determined based at least in part on the at least one pre-consumption image and the at least one post-consumption image of the food item;

determining a consumption pattern based at least in part on a list of foods identified from the multiple images and a consumption time associated with food on the list of foods;

displaying a suggestion based at least in part on the determined consumption pattern; and

updating the calorie measure based on the received calories consumed value.

2. The method of claim 1, further comprising:

displaying the calorie measure on a display, wherein displaying the calorie measure comprises displaying the updated calorie measure.

3. The method of claim 2, wherein displaying the calorie measure comprises persistently displaying the calorie measure.

4. The method of claim 2, wherein the display comprises a heads-up display (HUD).

5. The method of claim 1, further comprising:

receiving, from the server, an identifier associated with the food item, wherein the food item is identified based at least in part on the pre-consumption image of the food item.

6. The method of claim 5, further comprising:

receiving, from the server, portion information for the identified food item, the portion information determined based at least in part on the pre-consumption image of the food item.

7. The method of claim 6, further comprising:

receiving, from the server, calorie information for the food item, wherein the calorie information is based at least in part on the identified food and the determined portion information.

8. The method of claim 7, further comprising:

displaying the calorie information for the food item on a display.

9. The method of claim 7, further comprising:

transmitting at least one of the calorie information to a device or the calorie measure to the device; and

receiving feedback from the device based at least in part on the transmitted calorie information or the transmitted calorie measure.

10. The method of claim 1, further comprising:

receiving, from the server, a consumption event summary, wherein the consumption event summary comprises a list of foods consumed based at least in part on the food identified from the multiple images, the calories consumed value for each of item of food in the list of foods, a timestamp associated with a consumption period, and a duration of the consumption period.

11. A computing device configured for measuring calorie input, comprising:

a processor;

memory in electronic communication with the processor;

instructions stored in the memory, the instructions being executable by the processor to;

maintain a calorie measure;

capture multiple images of a field of view at a periodic timing interval;

analyze each image from the multiple images to identify whether an image of the field of view includes a food item;

automatically capture at least one pre-consumption image and at least one post-consumption image of the food item based at least in part on detecting the food item in the image of the field of view;

transmit the at least one pre-consumption image and the at least one post-consumption image of the food item to a server;

receive, from the server, a calories consumed value, wherein the calories consumed value is determined based at least in part on the at least one pre-consumption image and the at least one post-consumption image of the food item;

determine a consumption pattern based at least in part on a list of foods identified from the multiple images and a consumption time associated with food on the list of foods;

display a suggestion based at least in part on the determined consumption pattern; and

update the calorie measure based on the received calories consumed value.

12. The computing device of claim 11, wherein the instructions are executable by the processor to:

display the calorie measure on a display, wherein displaying the calorie measure comprises displaying the updated calorie measure.

13. The computing device of claim 12, wherein the instructions to display the calorie measure comprise instructions executable by the processor to persistently display the calorie measure.

14. The computing device of claim 12, wherein the display comprises a heads-up display (HUD).

15. The computing device of claim 11, wherein the instructions are executable the by the processor to:

receive, from the server, an identifier associated with the food item, wherein the food item is identified based at least in part on the pre-consumption image of the food item.

16. The computing device of claim 15, wherein the instructions are executable by the processor to:

receive, from the server, portion information for the identified food item, the portion information determined based at least in part on the pre-consumption image of the food item; and

receive, from the server, calorie information for the food item, wherein the calorie information is based at least in part on the identified food and the determined portion information.

17. The computing device of claim 16, wherein the instructions are executable by the processor to:

display the calorie information for the food item on the display.

18. A computer-program product to measure calorie input, the computer-program product comprising a non-transitory computer-readable medium having instructions thereon, the instructions being executable by a processor to:

maintain a calorie measure;

capture multiple images of a field of view at a periodic timing interval;

analyze each image from the multiple images to identify whether an image of the field of view includes a food item;

automatically capture at least one pre-consumption image and at least one post-consumption image of the food item based at least in part on detecting the food item in the image of the field of view;

transmit the at least one pre-consumption image and the at least one post-consumption image of the food item to a server;

receive, from the server, a calories consumed value, wherein the calories consumed value is determined based at least in part on the at least one pre-consumption image and the at least one post-consumption image of the food item;

determine a consumption pattern based at least in part on a list of foods identified from the multiple images and a consumption time associated with food on the list of foods;

display a suggestion based at least in part on the determined consumption pattern; and

update the calorie measure based on the received calories consumed value.
