Abstract

A system and method for positioning a pill to be ingested by a user in a field of view of an image acquisition camera. The method includes the steps of determining a desired location of the mouth of a user in a field of view of an image acquisition camera, determining a current position of a pill to be ingested by the user in the field of view of the image acquisition apparatus, and indicating on a display a movement to be made by the user to move the pill towards mouth of the user.

Claims

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 a user within a field of view of an image acquisition camera;

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

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;

indicating on the display a movement to be made by the user to move the current position of the medication relative to the image acquisition camera so as to move the medication image on the display towards the location target on the display;

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 step of indicating comprises a change in color.

6. The method of claim 1, wherein the desired location of the user is adjusted in accordance with one or more environmental factors.

7. The method of claim 1, wherein if the current position of the medication relative to the desired location of the user is laterally incorrect, the user is shown on the display an indication of desired movement of the medication image towards the location target, indicative of a direction in which to move the medication within the field of view of the image acquisition camera.

8. The method of claim 7, further comprising the step of providing a head tracing indicating a desired proper location of the image of the user.

9. The method of claim 8, wherein the indicator directs the user to move in the direction of the head tracing.

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 a user within a field of view of an 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 relative to the position of the mouth of the user;

indicating a movement to be made by the user to move the pill relative to the image acquisition camera so as to move the pill image on the display towards the location target on the display;

following movement of the pill in the field of view of the image acquisition camera by relative movement of the pill indicator 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 shown a directional indicator on the display indicative of a direction in which to move the pill within the field of view of the image acquisition camera.

12. The method of claim 11, wherein the directional indicator displayed on the display 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.

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

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 the 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, a medication image indicative of a current position of the medication in the acquired image of the medication and relative to the location target, and for indicating a desired movement of the medication to move the medication image towards the location target on the display so that the medication is moved towards the portion of the body part of the patient to which the medication is to be administered;

wherein the processor tracks movement of the medication, and the display displays movement of the medication indicator 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 provision of the indicated movement improves the ability of a user to properly administer the medication.

16. 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.

17. The system of claim 16, wherein the indication includes the use of a color displayed on the display.

18. 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.

19. The system of claim 18, 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.
