Method and apparatus for monitoring medication adherence

1. A method for positioning a medication relative to a user in a field of view of an image acquisition camera by providing automatic guidance to the user on how to position the medication, the method comprising the steps of:

displaying on a display an image of the user in the field of view of the image acquisition camera;

presenting a location target on the display indicative of a desired position relative to a portion of a body of the user in the field of view of the image acquisition apparatus;

acquiring an image of a medication within the field of view of the image acquisition camera by the image acquisition camera;

presenting the medication image on the display indicative of a current position of the medication relative to the position of the user;

following movement of the medication in the field of view of the image acquisition camera by relative movement of the medication image on the display; and

confirming interaction between the medication and the desired location of the portion of a body of the user when the location target and medication image are determined to be coextensive on the display.

2. The method of claim 1 , wherein if the current position of the user is too far from the image acquisition camera, an image of the user is displayed on the display in a small size.

3. The method of claim 2 , further comprising the step of providing a head tracing indicating a proper size that the image of the user should be.

4. The method of claim 3 , wherein an indicator is provided when the user is properly positioned, and the image of the user is coincident with the head tracing.

5. The method of claim 4 , wherein the indicator comprises a change in color.

6. The method of claim 3 , wherein the display further displays an indication if the user moves out of the field of view of the image acquisition camera and is therefore no longer displayed on the display.

7. The method of claim 1 , wherein the display further displays an indication if the medication moves out of the field of view of the image acquisition camera and is therefore no longer displayed on the display.

8. The method of claim 7 , wherein the indication instructs the user to keep the medication in the field of view.

9. The method of claim 1 , wherein the indication instructs the user to keep the medication in the field of view.

10. A method for positioning a pill to be ingested by a user in a field of view of an image acquisition camera, comprising the steps of:

displaying on a display an image of the user in the field of view of the image acquisition camera;

presenting a location target on the display indicative of a desired position of the mouth of the user in the field of view of the image acquisition camera;

presenting a pill image on the display indicative of a current position of a pill to be ingested by the user relative to the position of the mouth of the user;

following a movement of the pill in the field of view of the image acquisition camera by relative movement of the pill image on the display; and

confirming interaction between the pill and mouth of the user when the location target and pill image are determined to be coextensive on the display.

11. The method of claim 10 , wherein if the current position of the pill relative to the desired location of the mouth of the user is laterally incorrect, the user is instructed in which direction to move the pill within the field of view of the image acquisition camera.

12. The method of claim 11 , further comprising the step of indicating if the pill leaves the field of view of the image acquisition camera.

13. The method of claim 11 , wherein the instruction directs the user to move the pill in the direction of the target so that the pill image moves in the direction of the location target on the display.

14. A system for tracking positioning of a medication to be administered, comprising:

an image acquisition apparatus for acquiring an image of a patient within a field of view of the image acquisition apparatus, and for acquiring an image of a medication to be administered within the field of view of the image acquisition apparatus;

a processor for determining a position of a desired location of a portion of a body part of the patient to which the medication is to be administered in a field of view of the image acquisition apparatus, and determining a current position of the medication to be administered to the patient in the field of view of the image acquisition apparatus; and

a display for displaying a location target at a desired location of the portion of the body part of the patient in the acquired image of the patient to receive the medication, and a medication image indicative of a current position of the medication in the acquired image of the medication and relative to the location target,

wherein the processor tracks movement of the medication, and the display displays movement of the medication image in accordance with the tracked movement of the medication, and

wherein the processor confirms interaction between the medication and the portion of the body part of the patient to which the medication is to be administered when the location target and the medication image are determined to be coextensive on the display.

15. The system of claim 14 , wherein the image acquisition apparatus acquires a plurality of images of the patient and of the medication to track movement thereof.

16. The system of claim 15 , wherein interaction between the pill and mouth of the user is confirmed when the location target and pill image are determined to be coextensive in one or more of the plurality of images.

17. The system of claim 14 , wherein provision of the indicated movement improves the ability of the user to properly administer the medication.

18. The system of claim 14 , wherein the display further displays an indication if the medication to be administered moves out of the field of view of the image acquisition apparatus and is therefore no longer displayed on the display.

19. The system of claim 18 , wherein the indication includes the use of a color displayed on the display.
